AB  - Fourteen donepezil-like acetylcholinesterase (AChE) inhibitors from our library were
analyzed using reversed-phase thin-layer chromatography to assess their lipophilicity
and blood–brain barrier permeability. Compounds possessed N-benzylpiperidine and
N,N-diarylpiperazine moieties connected via a short carboxamide or amine linker.
Retention parameters RM
0, b, and C0 were considered as the measures of lipophilicity.
Besides, logD of the investigated compounds was determined chromatographically
using standard compounds with known logPow and logD values at pH 11. Experimentally
obtained lipophilicity parameters correlated well with in silico generated results,
and the effect of the nature of the linker between two pharmacophores and
substituents on the arylpiperazine part of the molecule was observed. As a result of
drug-likeness analysis, both Lipinski's rule of five and Veber's rule parameters were
determined, suggesting that examined compounds could be potential candidates for
further drug development. Principal component analysis was performed to obtain an
insight into a grouping of compounds based on calculated structural descriptors,
experimentally obtained values of lipophilicity, and AChE inhibitory activity.

AB  - Considering that acetylcholinesterase (AChE) inhibition is the most important mode of action expected of a potential drug used for the treatment of symptoms of Alzheimer’s disease (AD), our previous pilot study of 4-aminoquinolines as potential human cholinesterase inhibitors was extended to twenty-two new structurally distinct 4-aminoquinolines bearing an adamantane moiety. Inhibition studies revealed that all of the compounds were very potent inhibitors of AChE and butyrylcholinesterase (BChE), with inhibition constants (Ki) ranging between 0.075 and 25 µM. The tested compounds exhibited a modest selectivity between the two cholinesterases; the most selective for BChE was compound 14, which displayed a 10 times higher preference, while compound 19 was a 5.8 times more potent inhibitor of AChE. Most of the compounds were estimated to be able to cross the blood–brain barrier (BBB) by passive transport. Evaluation of druglikeness singled out fourteen compounds with possible oral route of administration. The tested compounds displayed modest but generally higher antioxidant activity than the structurally similar AD drug tacrine. Compound 19 showed the highest reducing power, comparable to those of standard antioxidants. Considering their simple structure, high inhibition of AChE and BChE, and ability to cross the BBB, 4-aminoquinoline-based adamantanes show promise as structural scaffolds for further design of novel central nervous system drugs. Among them, two compounds stand out: compound 5 as the most potent inhibitor of both cholinesterases with a Ki constant in low nano molar range and the potential to cross the BBB, and compound 8, which met all our requirements, including high cholinesterase inhibition, good oral bioavailability, and antioxidative effect. The QSAR model revealed that AChE and BChE inhibition was mainly influenced by the ring and topological descriptors MCD, Nnum, RP, and RSIpw3, which defined the shape, conformational flexibility, and surface properties of the molecules

AB  - Lipophilicity and ionization constant of sixteen fentanyl analogues were investigated by reversed-phase thin-
layer chromatography (RP-TLC). Fourteen compounds have nitrogen containing groups at C-3 position of the
piperidine ring and two compounds are 3-carbomethoxy derivatives of fentanyl. Among them, five are diaste-
reomeric cis/trans couples and six novel trans diastereomers. In addition, the lipophilicity and ionization constant
of fentanyl were also determined by the same method, as a reference. The physicochemical property, lip-
ophilicity, expressed as retention indices RM
0 , b, and C0, as well as PC1, was determined and correlated with in
silico values. Ionization constants were determined on the basis of the relationships between analyte’s retention
expressed as RF and mobile phase pH. Calculated structural descriptors together with the retention indices, were
subjected to the principal component analysis – PCA and hierarchical cluster analysis – HCA, in order to provide
basic insights into the similarities among the studied compounds. The blood – brain barrier (BBB) permeation
was investigated in the function of experimentally obtained values of lipophilicity, polar surface area and mo-
lecular weight. In general, results of the present research corroborate well with previously determined anti-
nociceptive activities of the investigated compounds, pointing out that besides the cis/trans isomerism, another
set of important parameters should be taken into account when designing new derivatives of C-3 substituted
fentanyl, especially lipophilicity, voluminosity and HBD/A character of the substituents. Accordingly, RP-TLC
can be considered as a valuable asset in the ligand-based drug design

AB  - Apple production generates large amounts of apple pomace including seeds, leading to high transportation costs, public health hazards and undesirable odor. A new reuse strategy of this kind of waste could solve environmental issues and/or create unconventional sources of health beneficial products. In total, seeds from 75 apple cultivars grown in Norway (both domestic and international) have been analyzed for the first time for oil content and fatty acid profile together with tocopherols and carotenoids quantification in defatted seeds. Seeds from cultivar Håkonseple had the highest oil content (22.10%), with linoleic, oleic acid, and palmitic acid as the most abundant fatty acids. The levels of β-carotene and lycopene carotenoids and α-tocopherol were the highest in defatted seeds of the cultivar Sureple Grøn. Principal component analysis separated cultivars according to the total oil content. The Norwegian apple cultivars Håkonseple, Kviteple, Tolleivseple, Vinterrosenstrips, and Tokheimseple are recommended for obtaining vegetable oil due to their high oil contents, while cultivar Sureple Grøn can be separated due to its high levels of β-carotene, lycopene and total tocopherols.

AB  - Growing antibiotic resistance creates a need to find new antimicrobial agents characterized by
diverse chemical structures and pharmaceutical activity. The higher plants synthesize many specialized
metabolites as a part of their normal metabolic activity and have been extensively used for
centuries in treatment of different diseases. They have a wide activity range depending on the
species, topography and climate, and may have different categories of active principles. In contrast
to conventional antimicrobial techniques, planar chromatography in combination with biological
detection can be an appropriate method of choice for fast, simple, and low-cost screening of plant
extract for successful detection of antimicrobial agents which can be good candidates for lead
compounds. To date, all bioautography steps such as chromatographic separation, detection with
bacteria cells, incubation, and visualization of bioactive bands were improved and optimized. This
review gives an overview of bioautography procedure from extraction to structure elucidation of
antimicrobial compounds from plants.

AB  - Pseudomonas aeruginosa is a leading cause of nosocomial infections that are becoming increasingly difficult to treat due to the occurrence of antibiotic resistant strains. Since P. aeruginosa virulence is controlled through quorum sensing, small molecule treatments inhibiting quorum sensing signaling pathways provide a promising therapeutic option. Consequently, we synthesized a series of N-octaneamino-4-aminoquinoline derivatives to optimize this chemotype’s antivirulence activity against P. aeruginosa via inhibition of pyocyanin production. The most potent derivative, which possesses a benzofuran substituent, provided effective inhibition of pyocyanin production (IC50 = 12 μM), biofilm formation (BFIC50 = 50 μM), and motility. Experimentally, the compound’s activity is achieved through competitive inhibition of PqsR, and structure–activity data were rationalized using molecular docking studies.

abstract = "Pseudomonas aeruginosa is a leading cause of nosocomial infections that are becoming increasingly difficult to treat due to the occurrence of antibiotic resistant strains. Since P. aeruginosa virulence is controlled through quorum sensing, small molecule treatments inhibiting quorum sensing signaling pathways provide a promising therapeutic option. Consequently, we synthesized a series of N-octaneamino-4-aminoquinoline derivatives to optimize this chemotype’s antivirulence activity against P. aeruginosa via inhibition of pyocyanin production. The most potent derivative, which possesses a benzofuran substituent, provided effective inhibition of pyocyanin production (IC50 = 12 μM), biofilm formation (BFIC50 = 50 μM), and motility. Experimentally, the compound’s activity is achieved through competitive inhibition of PqsR, and structure–activity data were rationalized using molecular docking studies.",

AB  - The inhibitory activities of selected cyclic urea and carbamate derivatives (1-13) toward alpha-glucosidase (alpha-Gls) in in vitro assay were examined in this study. All examined compounds showed higher inhibitory activity (IC50) against alpha-Gls compared to standard antidiabetic drug acarbose. The most potent was benzyl (3,4,5-trimethoxyphenyl) carbamate (12) with IC50 = 49.85 +/- 0.10 mu M. In vitro cytotoxicity of the investigated compounds was tested on three human cancer cell lines HeLa, A549 and MDA-MB-453 using MTT assay. The best antitumour activity was achieved with compound 2 (trans-5-phenethyl-1-phenylhexahydro-1H-imidazo[4,5-c] pyridin-2(3H)-one) against MDA-MB-453 human breast cancer cell line (IC50 = 83.41 +/- 1.60 mu M). Cyclic ureas and carbamates showed promising anti-alpha-glucosidase activity and should be further tested as potential antidiabetic drugs. The PLS model of preliminary QSAR study indicated that, in planing the future synthesis of more potent compounds, the newly designed should have the substituents capable of polar interactions with receptor sites in various positions, while avoiding the increase of their lipophilicity.

AB  - Antibiotic resistance has become a serious global threat to public health; therefore, improved strategies and structurally novel antimicrobials are urgently needed to combat infectious diseases. Here we report a new type of highly potent 4-aminoquinoline derivatives as quorum sensing inhibitors in Serratia marcescens and Pseudomonas aeruginosa, exhibiting weak bactericidal activities (minimum inhibitory concentration (MIC)  gt  400 mu M). Through detailed structure-activity study, we have identified 7-Cl and 7-CF3 substituted N-dodecylamino-4-aminoquinolines (5 and 10) as biofilm formation inhibitors with 50% biofilm inhibition at 69 mu M and 63 mu M in S. marcescens and P. aeruginosa, respectively. These two compounds, 5 and 10, are the first quinoline derivatives with anti-biofilm formation activity reported in S. marcescens. Quantitative structure-activity relationship (QSAR) analysis identified structural descriptors such as Wiener indices, hyper-distance-path index (HDPI), mean topological charge (MTC), topological charge index (TCI), and log D(o/w)exp as the most influential in biofilm inhibition in this bacterial species. Derivative 10 is one of the most potent quinoline type inhibitors of pyocyanin production described so far (IC50 = 2.5 mu M). While we have demonstrated that 5 and 10 act as Pseudomonas quinolone system (PQS) antagonists, the mechanism of inhibition of S. marcescens biofilm formation with these compounds remains open since signaling similar to P. aeruginosa PQS system has not yet been described in Serratia and activity of these compounds on acylhomoserine lactone (AHL) signaling has not been detected. Our data show that 7-Cl and 7-CF3 substituted N-dodecylamino-4-aminoquinolines present the promising scaffolds for developing antivirulence and anti-biofilm formation agents against multidrug-resistant bacterial species.

AB  - Lipophilicity is one of the essential properties influencing drug absorption, excretion and metabolism. It is used for screening viable drug candidates. Chromatographic behavior of thiepino[3,2-c: 6,7-c'] dipyridine and 16 benzothiepino[3,2-c] pyridine derivatives as potential antifungal drugs was studied using thin-layer chromatography under typical reversed-phase conditions and two microemulsion chromatographic systems. Seventeen chromatographic and nine in silico lipophilicity measures were estimated. They were compared by classical multivariate approaches: principal component analysis, hierarchical cluster analysis, and ranked and grouped by the non-parametricmethod-Sum of ranking differences. Two computational and two chromatographic descriptors from the typical reversed-phase conditions using acetone/ water mixtures emerged as the best candidates for lipophilicity estimation. The principal component scores related to typical reversed-phase conditions using dioxane/ water were ranked as statistically insignificant ( the worst). Microemulsion systems were positioned in between, performing worse than in silico estimates. Thiepine derivatives were ranked and grouped by sum of ranking differences, fusing multiple lipophilicity measures. In multicriteria maximization ranking, the compound substituted by phenyl group at position 8 was selected as the most lipophilic one. It is also the most active against Candida albicans. The ranking confirmed that introduction of phenyl core is essential for increasing the lipophilicity of the studied compounds.

AB  - A series of novel guanylhydrazones were designed, synthesized and characterized. All the compounds were screened for their antibacterial and antifungal activity. Compounds 26 and 27 showed excellent antibacterial activities against Staphylococcus aureus ATCC 25923 and Micrococcus luteus ATCC 379 with minimal inhibitory concentrations of 4 ae g mL(-1), and good antifungal activity against Candida parapsilosis ATCC 22019.

AB  - Lipophilicity is one of the essential properties influencing drug absorption, excretion and metabolism. It is used for screening viable drug candidates. Chromatographic behavior of thiepino[3,2-c: 6,7-c'] dipyridine and 16 benzothiepino[3,2-c] pyridine derivatives as potential antifungal drugs was studied using thin-layer chromatography under typical reversed-phase conditions and two microemulsion chromatographic systems. Seventeen chromatographic and nine in silico lipophilicity measures were estimated. They were compared by classical multivariate approaches: principal component analysis, hierarchical cluster analysis, and ranked and grouped by the non-parametricmethod-Sum of ranking differences. Two computational and two chromatographic descriptors from the typical reversed-phase conditions using acetone/ water mixtures emerged as the best candidates for lipophilicity estimation. The principal component scores related to typical reversed-phase conditions using dioxane/ water were ranked as statistically insignificant ( the worst). Microemulsion systems were positioned in between, performing worse than in silico estimates. Thiepine derivatives were ranked and grouped by sum of ranking differences, fusing multiple lipophilicity measures. In multicriteria maximization ranking, the compound substituted by phenyl group at position 8 was selected as the most lipophilic one. It is also the most active against Candida albicans. The ranking confirmed that introduction of phenyl core is essential for increasing the lipophilicity of the studied compounds.

AB  - Antibiotic resistance has become a serious global threat to public health; therefore, improved strategies and structurally novel antimicrobials are urgently needed to combat infectious diseases. Here we report a new type of highly potent 4-aminoquinoline derivatives as quorum sensing inhibitors in Serratia marcescens and Pseudomonas aeruginosa, exhibiting weak bactericidal activities (minimum inhibitory concentration (MIC)  gt  400 mu M). Through detailed structure-activity study, we have identified 7-Cl and 7-CF3 substituted N-dodecylamino-4-aminoquinolines (5 and 10) as biofilm formation inhibitors with 50% biofilm inhibition at 69 mu M and 63 mu M in S. marcescens and P. aeruginosa, respectively. These two compounds, 5 and 10, are the first quinoline derivatives with anti-biofilm formation activity reported in S. marcescens. Quantitative structure-activity relationship (QSAR) analysis identified structural descriptors such as Wiener indices, hyper-distance-path index (HDPI), mean topological charge (MTC), topological charge index (TCI), and log D(o/w)exp as the most influential in biofilm inhibition in this bacterial species. Derivative 10 is one of the most potent quinoline type inhibitors of pyocyanin production described so far (IC50 = 2.5 mu M). While we have demonstrated that 5 and 10 act as Pseudomonas quinolone system (PQS) antagonists, the mechanism of inhibition of S. marcescens biofilm formation with these compounds remains open since signaling similar to P. aeruginosa PQS system has not yet been described in Serratia and activity of these compounds on acylhomoserine lactone (AHL) signaling has not been detected. Our data show that 7-Cl and 7-CF3 substituted N-dodecylamino-4-aminoquinolines present the promising scaffolds for developing antivirulence and anti-biofilm formation agents against multidrug-resistant bacterial species.

AB  - A novel series of thiepine derivatives were synthesized and evaluated as potential antimicrobials. All the synthesized compounds were evaluated for their antimicrobial activities in vitro against the fungi Candida albicans (ATCC 10231), C.parapsilosis (clinical isolate), Gram-negative bacterium Pseudomonas aeruginosa (ATCC 44752), and Gram-positive bacterium Staphylococcus aureus (ATCC 25923). Synthesized compounds showed higher antifungal activity than antibacterial activity, indicating that they could be used as selective antimicrobials. Selected thiepines efficiently inhibited Candida hyphae formation, a trait necessary for their pathogenicity. Thiepine 8-phenyl[1]benzothiepino[3,2-c]pyridine (16) efficiently killed Candida albicans at 15.6g/mL and showed no embryotoxicity at 75g/mL. Derivative 8-[4-(4,5-dihydro-1H-imidazol-2-yl)phenyl][1]benzothiepino[3,2-c]pyridine (23) caused significant hemolysis and in vitro DNA interaction. The position of the phenyl ring was essential for the antifungal activity, while the electronic effects of the substituents did not significantly influence activity. Results obtained from in vivo embryotoxicity on zebrafish (Danio rerio) encourage further structure optimizations.

AB  - The chromatographic behaviour of series of 4-amino-7-chloroquinoline (4,7-ACQ) based compounds was studied by reversed-phase thin-layer chromatography (RPTLC) with binary mobile phases containing water and the organic modifiers, DMSO or acetone. The lipophilicity of the studied compounds was determined by extrapolation of retention parameters R-M to pure water content in mobile phase. In order to obtain some basic insight into the chromatographic behaviour and structural features of investigated compounds, PCA was performed on both chromatographic data (R-M values) and calculated 2D and 3D structural descriptors. Both QSRR and QSAR models were built by means of the partial least squares (PLS) statistical method. It was found that descriptors which encode hydrophobic (dispersive) interactions have positive influence on retention, while influence of descriptors encoding polar interactions was negative. According to the obtained PLS model for inhibition of botulinum neurotoxin serotype A light chain, hydrophobic interactions influence positively on the mechanism of action of the investigated 4,7-ACQ while polar interactions are less favoured. Contrary, the results of PLS modelling of activity against Plasmodium falciparum strains (W2, D6 and TM91C235) indicate that higher polarity of 4,7-ACQ contribute to their higher antimalarial activity.
