AB  - Heterocyclic pharmacophores such as thiazole and quinoline rings have a significant role in medicinal chemistry. They are considered privileged structures since they constitute several Food and Drug Administration (FDA)-approved drugs for cancer treatment. Herein, we report the synthesis, in silico evaluation of the ADMET profiles, and in vitro investigation of the anticancer activity of a series of novel thiazolyl-hydrazones based on the 8-quinoline (1a–c), 2-quinoline (2a–c), and 8-hydroxy-2-quinolyl moiety (3a–c). The panel of several human cancer cell lines and the nontumorigenic human embryonic kidney cell line HEK-293 were used to evaluate the compound-mediated in vitro anticancer activities, leading to [2-(2-(quinolyl-8-ol-2-ylmethylene)hydrazinyl)]-4-(4-methoxyphenyl)-1,3-thiazole (3c) as the most promising compound. The study revealed that 3c blocks the cell-cycle progression of a human colon cancer cell line (HCT-116) in the S phase and induces DNA double-strand breaks. Also, our findings demonstrate that 3c accumulates in lysosomes, ultimately leading to the cell death of the hepatocellular carcinoma cell line (Hep-G2) and HCT-116 cells, by the mechanism of autophagy inhibition.

AB  - The binding of ubiquitous serum ligands (free fatty acids) to human serum albumin (HSA)
or its glycation can affect thiol group reactivity, thus influencing its antioxidant activity. The effects
of stearic acid (SA) and glucose binding on HSA structural changes and thiol group content and
reactivity were monitored by fluoroscopy and the Ellman method during a 14-day incubation in
molar ratios to HSA that mimic pathophysiological conditions. Upon incubation with 5 mM glucose,
HSA glycation was the same as HSA without it, in three different HSA:SA molar ratios (HSA:SA-
1:1-2-4). The protective effect of SA on the antioxidant property of HSA under different glucose
regimes (5-10-20 mM) was significantly affected by molar ratios of HSA:SA. Thiol reactivity was fully
restored with 5–20 mM glucose at a 1:1 HSA:SA ratio, while the highest thiol content recovery was in
pathological glucose regimes at a 1:1 HSA:SA ratio. The SA affinity for HSA increased significantly
(1.5- and 1.3-fold, p < 0.01) with 5 and 10 mM glucose compared to the control. These results deepen
the knowledge about the possible regulation of the antioxidant role of HSA in diabetes and other
pathophysiological conditions and enable the design of future HSA-drug studies which, in turn, is
important for clinicians when designing information-based treatments.

AB  - This study aimed to purify, characterise and stabilise the natural food colourant, R-phycocyanin (R-PC), from the red algae Porphyra spp. (Nori). We purified R-PC from dried Nori flakes with a high purity ratio (A618/A280 ≥ 3.4) in native form (α-helix content 53%). SAXS measurements revealed that R-PC is trimeric ((αβ)3) in solution. The thermal denaturation of α-helix revealed one transition (Tm at 52 °C), while the pH stability study showed R-PC is stable in the pH range 4–8. The thermal treatment of R-PC at 60 °C has detrimental and irreversible effects on R-PC colour and antioxidant capacity (22 % of residual capacity). However, immobilisation of R-PC within calcium alginate beads completely preserves R-PC colour and mainly retains its antioxidant ability (78 % of residual capacity). Results give new insights into the stability of R-PC and preservation of its purple colour and bioactivity by encapsulation in calcium alginate beads.

AB  - This study investigates the impact of Porphyra sp. extracts on HT29 cell line growth and viability at reduced serum conditions. The concentration-dependent effects of phycobiliproteins (PBPs) on cell proliferation were examined over various time intervals. Lower concentrations of PBPs (20 μg/mL) demonstrated an increase in HT29 cell viability after 48 hours and 5 days of cultivation at reduced serum concentration (final serum concentration was in the range from 5 to 8%). This suggests a potential positive influence on cell proliferation, likely due to their antioxidant properties. Conversely, higher concentrations of PBPs exhibited inhibitory effects on cell growth, possibly due to cytotoxicity at elevated levels. Remarkably, when HT29 cells were cultured solely in algal extract without fetal calf serum (FCS), complete growth inhibition was observed after 72
hours. This finding underscores the insufficient nutrient and growth factor provision of PBPs alone for sustaining cell viability. Morphological differences observed in cells cultured with 70 μg/mL of PBPs indicated potential alterations in cellular morphology. Notably, 70 μg/mL of PBPs in RPMI medium with 5% FCS displayed growth inhibition compared to the control (5% FCS). Furthermore, we assessed HT29 cell adaptability to changes in FCS concentration and PBP supplementation. Cells incubated under varying FCS and PBP conditions were subcultured into RPMI medium with lower FCS concentration and PBPs from Porphyra. The viability of cells following subculturing indicated sustained adaptability to reduced FCS levels. Overall, this study provides valuable insights into the concentration-dependent effects of PBPs from Porphyra extracts
on HT29 cell growth and viability. The findings underscore the potential benefits of PBPs at lower concentrations for cell proliferation at reduced serum conditions and reveal the adaptability of HT29 cells to changing culture conditions.

AB  - Common to all biological systems and living organisms are molecular interactions, which
may lead to specific physiological events. Most often, a cascade of events occurs, establishing an equilibrium between possibly competing and/or synergistic processes. Biochemical pathways that sustain life depend on multiple intrinsic and extrinsic factors contributing to aging and/or diseases. This article deals with food antioxidants and human proteins from the circulation, their interaction, their effect on the structure, properties, and function of antioxidant-bound proteins, and the possible impact of complex formation on antioxidants. An overview of studies examining interactions between individual antioxidant compounds and major blood proteins is presented with findings. Investigating antioxidant/protein interactions at the level of the human organism and determining antioxidant distribution between proteins and involvement in the particular physiological role is a very complex and challenging task. However, by knowing the role of a particular protein in certain pathology or aging, and the effect exerted by a particular antioxidant bound to it, it is possible to recommend specific food intake or resistance to it to improve the condition or slow down the process.

abstract = "Common to all biological systems and living organisms are molecular interactions, which
may lead to specific physiological events. Most often, a cascade of events occurs, establishing an equilibrium between possibly competing and/or synergistic processes. Biochemical pathways that sustain life depend on multiple intrinsic and extrinsic factors contributing to aging and/or diseases. This article deals with food antioxidants and human proteins from the circulation, their interaction, their effect on the structure, properties, and function of antioxidant-bound proteins, and the possible impact of complex formation on antioxidants. An overview of studies examining interactions between individual antioxidant compounds and major blood proteins is presented with findings. Investigating antioxidant/protein interactions at the level of the human organism and determining antioxidant distribution between proteins and involvement in the particular physiological role is a very complex and challenging task. However, by knowing the role of a particular protein in certain pathology or aging, and the effect exerted by a particular antioxidant bound to it, it is possible to recommend specific food intake or resistance to it to improve the condition or slow down the process.",

AB  - The biological activity of six structurally similar tetradentate Schiff base copper(II) complexes, namely [Cu(ethylenediamine-bis-acetylacetonate)] (CuAA) and five derivatives where two methyl groups are replaced by phenyl, (CuPP), CF3 (CuTT) or by mixed groups CH3/CF3 (CuAT), Ph/CF3 (CuPT), and Ph/CH3 (CuAP) has been investigated. The set of antioxidant assays was performed, and the results were expressed as IC50 and EC50 values. The series of complexes showed interesting bioactivity and were investigated for the determination of antioxidant, antifungal, antimicrobial, and cytotoxic activity. A significant antioxidant behavior was exhibited by complex CuAA, greater than Trolox in the Oxygen Radical Absorbance Capacity (ORAC) assay. Antibacterial assay over Gram-positive and Gram-negative pathogenic bacterial strains and some fungal pathogens were studied. Antiproliferative activity of complexes in two human tumor cell lines, breast adenocarcinoma MCF-7, colon adenocarcinoma LS-174, and normal fibroblast cells-MRC-5, examined the effect on cell cycle progression. The significant cytotoxic potential, comparable to cisplatin cytotoxicity, was determined in human breast cancer cell line-MCF-7 with IC50 values being 17.53–31.40 μM and human colon cancer cell line-LS-174 with IC50 values being 15.22–23.92 μM. All tested compounds showed nearly twice more selectivity toward cancer cell lines than normal cells. The interactions of complexes with human serum albumin (HSA), the most prominent protein in plasma, were investigated using spectroscopic fluorescence techniques. The complexes bind to human serum albumin at multiple sites (n = 0.2–1.9), displaying a moderate binding constant Ka = 4.1–12.4 × 104 M−1. The molecular docking experiment effectively showed complex binding to HSA and DNA molecular fragments.

AB  - Purple R-phycocyanin is a protein from red algae with the potential for application in the food industry (colorant) and wastewater treatment (binding of heavy metals). Analytical grade R-phycocyanin was purified from the buffered extract of dried Nori flakes (Porphyra spp.) by combining ammonium sulfate precipitation, hydroxyapatite, and DEAE-Sepharose column chromatography. The multimeric protein had absorption maxima characteristic for phycoerythrobilin (at 580 nm) and phycocyanobilin (at 640 nm) chromophores, high α- helical content, and melting temperature of 52°C. The secondary R-PC structure was stable under a wide range of pH values (3–9). R-phycocyanin immobilized in calcium alginate beads showed increased thermal stability and preserved antioxidant activity.

AB  - Cultured meat requires less land and water and is less polluting, but still costly. The critical challenge in cultivated meat science is identifying and developing bovine serum albumin alternatives as the key component in cell media. Phycobiliproteins (PBPs) from micro- and macroalgae are promising candidates for albumin replacement due to their high abundance and well-known excellent antioxidative and metal-binding activities of covalently attached tetrapyrrole chromophores. Considering the importance of fatty acids (FA) binding by albumin for cell cultivation, the additional prerequisites for developing PBPs as albumin replacement components is their validation for the ability to bind FA. This study aims to examine the ability of C-phycocyanin (C-PC), the major PBP of microalgae Arthrospira platensis, to bind seven fatty acids (stearic, palmitic, oleic, elaidic, linoleic, linolenic and docosahexaenoic acid). For this purpose, we employed various optical spectroscopy techniques (fluorescence, CD, and VIS absorption spectroscopy). The protein fluorescence quenching approach demonstrated FA binding affinities ranging from 0.42 to 2.4 x 105 M−1, with the ability of FA to bind at different sites on C-PC. Fatty acid binding induces substantial changes in the VIS absorption spectra of C-PC, indicating the FA are attached in the vicinity of C-PC chromophores. On the other hand, CD spectroscopy did not show significant effects of FA binding on C-PC secondary structure content. Overall, this study revealed C-PC's significant potential in binding FA, the critical prerequisite to replacing albumin for developing animal-free cell media for meat cultivation.

AB  - Porphyra  sp.(Nori),  red  algae,  is  a  highly  nutritious  superfood  due  to  its  abundance  of  vitamins, minerals,    antioxidants,    and    proteins,    including    R-phycocyanin    (R-PC),    a    purple-coloured phycobiliprotein. However, the limited stability of R-PC poses a challenge to itsapplication in the food industry. This study aimed to purify, characterize, and stabilize R-PC for use as a natural colourant in the  food,  cosmetic,  and  pharmaceutical  industries.  Highly  pure  R-PC  was  obtained  from  Nori  flakes, and its trimeric ((αβ)3) structure was determined using SAXS measurements. Far-UV CD spectroscopy revealed the dominant secondary structure to be α-helix, and R-PC was stable in the pH range of 4 to 8. However, thermal treatment at 60 °C had detrimental and irreversible effects on the R-PC's colour and antioxidant   capacity   (22%   residual   capacity).   Encapsulation   within   the   calcium   alginate   beads preserved  its purple colour and retained its  antioxidant capacity (78% residual capacity). Our findings demonstrate  the  potential  of  R-PC  as a  replacement  for  toxic  synthetic  dyes  and  highlight  the importance of stabilizing R-PC through encapsulation for its bioactivity and colour preservation.

AB  - C-phycocyanin (C-PC), a blue, light-harvesting protein from Arthrospira platensis, is known for industrial application as a food colourant. However, thermal treatment has detrimental effects on C-PC colour due to sensitivity to high temperatures; therefore, its application in the food industry is limited. Hence, stabilisation of the C-PC structure by adding small, food-derived molecules (e.g. sugars) or applying an alternative approach to thermal treatment, such as high-pressure (HP), may allow broader use of this protein. We aimed to study HP and thermal stability of C-PC in the presence of selected sugars (glucose, fructose and sucrose). Ex-situ absorption spectroscopy showed that 18% of glucose, sucrose and fructose solutions, upon incubation at 65℃, exhibit higher colour preservation (91.4, 52.9 and 52.5%, respectively) in comparison to the control (46.9%). HP treatment of C-PC at 450 MPa in 18% solutions of glucose, sucrose and fructose showed 90.1, 93.2 and 74.2% of residual absorbance, respectively, while the HP treatment of control gives 82.3% of residual absorbance. In situ thermal fluorescence measurements revealed that free C-PC has a melting point (Tm) of 55.4°C. In comparison, glucose and sucrose increase Tm of C-PC to 64.4 and 61.4°C, respectively, while fructose does not significantly influence C-PC melting point. In situ HP fluorescence study confirms the stabilisation effects of sugars: the transition pressure (P1/2) of C-PC (230 MPa) is substantially increased in the presence of glucose (277 MPa), sucrose (304 MPa) and fructose (273 MPa). These results showed that HP treatment has significantly less detrimental effects on C-PC colour stability than thermal treatment, and the overall stability of C-PC is substantially increased in the presence of sugars. In contrast, the sugar type determines the stabilisation effect's extent. Consequently, HP treatment of C-PC-containing food could provide an alternative to thermal processing to avoid losing its vivid blue colour.

We aimed to study HP and thermal stability of C-PC in the presence of selected sugars (glucose, fructose and sucrose). Ex-situ absorption spectroscopy showed that 18% of glucose, sucrose and fructose solutions, upon incubation at 65℃, exhibit higher colour preservation (91.4, 52.9 and 52.5%, respectively) in comparison to the control (46.9%). HP treatment of C-PC at 450 MPa in 18% solutions of glucose, sucrose and fructose showed 90.1, 93.2 and 74.2% of residual absorbance, respectively, while the HP treatment of control gives 82.3% of residual absorbance. In situ thermal fluorescence measurements revealed that free C-PC has a melting point (Tm) of 55.4°C. In comparison, glucose and sucrose increase Tm of C-PC to 64.4 and 61.4°C, respectively, while fructose does not significantly influence C-PC melting point. In situ HP fluorescence study confirms the stabilisation effects of sugars: the transition pressure (P1/2) of C-PC (230 MPa) is substantially increased in the presence of glucose (277 MPa), sucrose (304 MPa) and fructose (273 MPa). These results showed that HP treatment has significantly less detrimental effects on C-PC colour stability than thermal treatment, and the overall stability of C-PC is substantially increased in the presence of sugars. In contrast, the sugar type determines the stabilisation effect's extent. Consequently, HP treatment of C-PC-containing food could provide an alternative to thermal processing to avoid losing its vivid blue colour.",

AB  - The Zn(II) complexes [Zn(HLSe2)2](NO3)2∙CH3OH (2-NO3-Se) and [Zn(HLSe3)2](NO3)2·DMF (3-NO3-Se) with selenazolyl-hydrazone ligands 4-(4-methoxyphenyl)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3-selenazole (HLSe2) and 4-(4-methylphenyl)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3-selenazole (HLSe3) have been synthesized and characterized using singe crystal X-ray diffraction analysis. Antiproliferative activities of 2-NO3-Se and 3-NO3-Se, the corresponding ligands and sulphur isosteres of the complexes and the ligands were determined on non-malignant HTR-8/SVneo extravillous trophoblast cell line and malignant JEG-3 and JAr choriocarcinoma cell lines. All Zn complexes exhibited cytotoxic effect, comparable to that of a reference metal-based drug, cisplatin. The antioxidant activity of all compounds was determined in three antioxidant assays: ORAC (Oxygen Radical Absorbance Capacity), ABTS [(2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt] and CERAC [Ce(IV)-based reducing capacity]. As a result of synergy between Zn(II) and selenazolyl-hydrazone ligands, the complexes 2-NO3-Se and 3-NO3-Se appeared to be more active than Trolox, which is not the case for their sulfur counterparts. In-silico calculations of ADME properties pointed that the compounds possess some of desirable Lipinski rule principles. Applied algorithms did not report the compounds as potential PAINS or covalent inhibitors, although due to high molecular weight none of the compounds represent a potential lead compound. Toxicity prediction of the compounds is performed using machine learning models. The complexation of the ligands most likely reduces their toxicity or reduces their negative metabolic effects.

AB  - Interest in Cd complexes has been growing in recent years. Cd complexes are considered a potential solution in the search for novel antibiotics that can fight antimicrobial resistance. In addition, Cd complexes draw attention to material chemistry. The main objective of this work was to prepare the first Cd(II) complexes with anionic forms of pyridine-based thiazolyl hydrazone (THs) ligands HLS2 [(E)-4-(4-methoxyphenyl)-2-(2-[pyridine-2-ylmethylene]hydrazinyl)thiazole] and HLS3 [(E)-2-(2-[pyridine-2-ylmethylene]hydrazinyl)-4-(p-tolyl)thiazole] and perform their structural and spectroscopic characterization, as well as stability in solution and upon heating. Studies related to their biological activities and possible electrochromic applications are also being conducted. Complexes [Cd(HLS2)2] (1) and [Cd(HLS3)2] (2) have been characterized by a single-crystal X-ray diffraction and computational analysis of intermolecular interactions responsible for their solid-state structures was performed. Thermal stability of 1 and 2 in the solid-state was analyzed by TGA/MS, where as their solution stability was determined by the spectrophotometric titration method. Electrochemical and in situ UV–Vis spectroelectrochemical analyses of 1 and 2 were carried out to determine redox mechanisms and the influence of the substituents and electrolytes on their redox responses. The antioxidant capacity of both complexes was tested in antioxidant assays, while their antimicrobial activity was tested against five Gram-positive and four Gram-negative bacteria, as well as against three fungi. The obtained results indicate their potent antioxidant capacity. The antimicrobial activity of investigated compounds on almost all tested bacterial strains was stronger than that of the standard antibiotic erythromycin. The results of docking studies indicate that the minor groove DNA is the possible biological target of 1 and 2.

AB  - In the present work, the α,β-double bond of the aroylacrylic acid phenylamides was suitably modified to optimize the toxicity–antiproliferative activity ratio of the resulting compounds 1–5. The phenylamides were modified by Michael's addition of suitably chosen piperidine-containing fragments: 1-amino-N-benzylpiperidine (a1), 4-benzylpiperidine (a2), and N,N-dimethyl-N-[2-(1-piperazinyl)-ethyl]amine (a3). The compounds exerted micromolar activity toward three cancer cell lines, A549, LoVo, and Skov-3, causing apoptotic cell death. It was shown that the nature of the cyclic amine moiety at position C2 of the compounds is probably the primary determinant of anticancer activity toward tested cell lines and the acute toxicity toward brine shrimp (Artemia salina). The majority of compounds revealed the ability to vigorously induce mitochondrial superoxide anion generation in all treated cell lines, which together with cell cycle arrest at the S phase and activation of intrinsic caspase cascade, indicates the possibility that apoptosis was triggered due to irreparable chromosomal damage by acute oxidative stress. Two derivatives also exerted significant antibacterial activity with one order of magnitude higher potency than chloramphenicol in most of the investigated bacterial strains. Also, the drug-like properties for all compounds were estimated by available software tools.

The phenylamides were modified by Michael's addition of suitably chosen piperidine-containing fragments: 1-amino-N-benzylpiperidine (a1), 4-benzylpiperidine (a2), and N,N-dimethyl-N-[2-(1-piperazinyl)-ethyl]amine (a3). The compounds exerted micromolar activity toward three cancer cell lines, A549, LoVo, and Skov-3, causing apoptotic cell death. It was shown that the nature of the cyclic amine moiety at position C2 of the compounds is probably the primary determinant of anticancer activity toward tested cell lines and the acute toxicity toward brine shrimp (Artemia salina). The majority of compounds revealed the ability to vigorously induce mitochondrial superoxide anion generation in all treated cell lines, which together with cell cycle arrest at the S phase and activation of intrinsic caspase cascade, indicates the possibility that apoptosis was triggered due to irreparable chromosomal damage by acute oxidative stress. Two derivatives also exerted significant antibacterial activity with one order of magnitude higher potency than chloramphenicol in most of the investigated bacterial strains. Also, the drug-like properties for all compounds were estimated by available software tools.",

AB  - The emergence of the coronavirus SARS-CoV-2 has attracted attention of the whole scientific community. The SARS-CoV-2 spike (S) protein plays the most important role in viral attachment to host receptor angiotensin-converting enzyme 2 (ACE2), via the receptor-binding domain (RBD), fusion and entry into the host, and it serves as a target for the development of antibodies, entry inhibitors and vaccines. It has been demonstrated that phycocyanobilin (PCB), a bioactive open-chain tetrapyrrole chromophore of phycocyanin (PC), chromoprotein derived from the cyanobacterium Arthrospira platensis, can bind a plethora of different proteins, both in a noncovalent and covalent manner. This study aimed to investigate interactions of PCB with S protein and RBD respectively. Electrophoretic techniques, fluorescence spectroscopy, and inhibition of S–PCB and RBD–PCB covalent adduct formation using iodoacetamide and N-ethylmaleimide, were employed to examine interactions of PCB with S protein and RBD, while the effects of PCB binding on RBD structure were studied by CD spectroscopy. SDS-PAGE with Zn2+ staining has revealed that PCB covalently binds to both S protein and RBD, via free cysteine residues. Binding constants determined by the fluorescence quenching method were: 2.1×107 M–1 for PCB and S protein and 8.4×104 M–1 for PCB and RBD. Far-UV circular dichroism spectra showed that the binding of PCB influences RBD structure by decreasing the disordered structure content. Due to moderately strong noncovalent interactions of PCB with S protein and RBD, as well as covalent adducts formation, it may exert one of its many bioactive effects via impact on S protein binding to ACE2 receptor.

AB  - To minimize the impact of artificial food colouring (e.g., in drinks) on health, chemical dyes are increasingly replaced by natural 
ones. C-phycocyanin (C-PC), hexameric light-harvesting phycobiliprotein from cyanobacteria Artrhorspira platensis, has been 
proposed as an alternative. The intensive blue colour of C-PC arises from phycocyanobilin (PCB), the covalently attached 
tetrapyrrole chromophores. The presence of PCB chromophores gives C-PC a broad range of bioactive effects (antioxidant, 
anticancer, and immunomodulatory ones), substantially increasing their potential for applications in the food industry. However, 
C-PC issensitive to temperature, and its colour significantly diminishes by thermal treatment, limiting its use in the food industry. 
Hence, improving C-PC stability is the major challenge for successful application in food and beverage colouring. It is well 
known that binding small, high-affinity ligands significantly improve protein stability. Therefore, selecting food-derived ligands 
(such as vitamins, polyphenols, sugars, etc.) with the ability to bind C-PC firmly could be a promising strategy to increase the
C-PC stability and preserve its colour, which should increase its application potential in the food industry.
The main aim of this study is to characterize the binding of selected food-derived ligands (including quercetin, coenzyme Q10, 
gallic acid, vanillic acid, vanillin, resveratrol, glucose, fructose, sucrose, vitamin K, menthol, and dihydrolipoic acid) to C-PC 
by standard spectroscopic methods (UV/VIS absorption spectroscopy, spectrofluorimetry, and CD spectroscopy). Quercetin has
the strongest binding affinity to C-PC (Ka~3.7x105 M-1
), and its effects on C-PC structure and stability have been further 
investigated. CD spectroscopy revealed that quercetin induces stabilization of the protein secondary structure under simulated 
physiological conditions, while the conformation of the PCB chromophore is altered upon quercetin binding. Furthermore, 
quercetin binding increases the thermal stability of C-PC. 
Overall, our study revealed the ability of high-affinity, food-derived ligands to increase the stability of C-PC, which may enhance 
its application potential in the food industry.

AB  - Phycocyanobilin (PCB) is an open-chain tetrapyrrole chromophore of phycocyanin (PC), chromoprotein derived from the cyanobacterium Arthrospira platensis. Our group has previously demonstrated the potential of PCB to covalently modify free cysteine residue of proteins using food protein β-lactoglobulin as a model protein. Relying on the proven ability of PCB to be attached to sulfhydryl groups of proteins, we propose a new method for covalent attachment of PCB to potentially any protein. We used Traut’s reagent (TR, 2-iminothiolane) to introduce free sulfhydryl groups in the model protein, bovine serum albumin (BSA), by modifying its lysine residues. All tested molar ratios of TR per mole of protein successfully modified BSA. A higher degree of modification by TR induced more profound alterations of BSA structure, as evidenced by near-UV and far-UV circular dichroism spectroscopy. At the same time, minor changes in BSA oligomerization and aggregation profile occurred with increasing TR molar ratio. PCB was covalently attached to introduced sulfhydryl groups at pH 9 at 20–fold molar ratio of PCB per mole of protein. An increase in the molar ratio of TR per mole of BSA leads to amplification of fluorescent signal of PCB-modified BSA, most significantly observed starting from 50-fold and higher TR ratios. Using BSA as a model protein, a 50-fold molar excess of TR seems to be the optimal choice for balancing a satisfactory signal amplification level and the negative effect on protein structure. BSA covalently modified with PCB has higher antioxidative activity than free BSA. The proposed method thus serves as a proof of concept for labeling virtually any protein with PCB as means of either functionalization through covalent attachment of bioactive PCB or obtaining fluorescent probes for application in fluorescence-based techniques.

abstract = "Phycocyanobilin (PCB) is an open-chain tetrapyrrole chromophore of phycocyanin (PC), chromoprotein derived from the cyanobacterium Arthrospira platensis. Our group has previously demonstrated the potential of PCB to covalently modify free cysteine residue of proteins using food protein β-lactoglobulin as a model protein. Relying on the proven ability of PCB to be attached to sulfhydryl groups of proteins, we propose a new method for covalent attachment of PCB to potentially any protein. We used Traut’s reagent (TR, 2-iminothiolane) to introduce free sulfhydryl groups in the model protein, bovine serum albumin (BSA), by modifying its lysine residues. All tested molar ratios of TR per mole of protein successfully modified BSA. A higher degree of modification by TR induced more profound alterations of BSA structure, as evidenced by near-UV and far-UV circular dichroism spectroscopy. At the same time, minor changes in BSA oligomerization and aggregation profile occurred with increasing TR molar ratio. PCB was covalently attached to introduced sulfhydryl groups at pH 9 at 20–fold molar ratio of PCB per mole of protein. An increase in the molar ratio of TR per mole of BSA leads to amplification of fluorescent signal of PCB-modified BSA, most significantly observed starting from 50-fold and higher TR ratios. Using BSA as a model protein, a 50-fold molar excess of TR seems to be the optimal choice for balancing a satisfactory signal amplification level and the negative effect on protein structure.

AB  - C-phycocyanin (C-PC), the major protein of cyanobacteria Arthrospira platensis, is a blue
pigment that primarily transfers energy during photosynthesis.It has diverse
biotechnological applications since it can be used in nutraceutical, cosmetics,
pharmaceutical industries, and biomedical research.Its intensive blue colour and strong
antioxidant activity give C-PC significant potential to replace synthetic colourants in the
food industry. However, thermal treatment of food has detrimental effects on C-PC colour
due to sensitivity to higher temperatures; therefore,the application of this natural colourant
in food and other products is limited. Hence, improving C-PC stability is the major
challenge for successful application in food and beverages colouring. In the light of this,we
aim to investigate the thermal stability of C-PC in the presence of selected sugars (glucose,
fructose and sucrose), commonly used in the food industry. Ex-situabsorption
spectrophotometryshowed that 18% solution (w/v) of glucose, sucrose and fructose at pH
7,upon incubation at 65℃, exhibit 91.4, 52.9 and 52.5% of colour preservation,
respectively.In situ fluorescence measurements revealed that free C-PC has a melting point
of 55.4°C, while the presence of glucose and sucrose increases the melting point of C-PC
to 64.4 and 61.4°C, respectively. On the other hand, fructose does not significantly
influence the C-PC melting point. These results show that the thermal stability ofthe CPCsolution is substantially increased in the presence of sugars, while the type of sugar
significantly determines the extent of the stabilisation effect. Overall, our study provides
the strategy for enhancing the application potential of C-PC as natural food colourant,
providing a food product with vivid blue colour and substantial antioxidant activities.

AB  - Phycobiliproteins are major photosynthetic accessory pigments in cyanobacteria and red
algae. Their vivid colours arise from covalently attached tetrapyrrole chromophores. The
exciting characteristic of tetrapyrrole chromophores is the ability to bind metal ions. Heavy
metals are among the most abundant and most dangerous environmental pollutants, and
their removal from the environment is a crucial challenge. Therefore, utilizing PBPs-metal
binding properties could be helpful in heavy metal detection and/or removal. The main aim
of this study is to characterize the binding of selected heavy metal ions (Hg2+, Pb2+, Cd2+)
to R-phycocyanin (R-PC) isolated and purified from red algae Porphyra spp.The protein
fluorescence quenching approach revealed the strong binding affinity of R-PC to Hg2+
(Kd~0.1 μM), while protein binding to Pb2+ and Cd2+ is lower (Kd~3 μM) but still in the
high to moderate range. Circular dichroism spectroscopy demonstrated the ability of Hg2+,
Pb2+ and Cd2+ to slightly -helical content) in
R-PC. Our results indicatethat R-PC could beexploited as a potential biosensor for heavy
metal ions detection (especially Hg2+) in aquatic systems as well as in their removal from
the environment (e.g. waste-water management).
