AB  - Rhenium complexes merit particular attention in the area of metallodrug design due to rhenium’s broad spectrum of oxidation states and consequently, the possibility to design compounds of a great structural diversity. Thus, the synthesis, chemical characterization and antitumor activity in vitro of the three Re(V) complexes is described. Novel compounds were obtained via reaction of [ReOCl3(PPh3)2] with corresponding ligands (pyridine-2-carboxylic acid, 3-methylpyridine-2-carboxylic acid and 6-methylpyridine-2-carboxylic acid) in acetonitrile at 78 °C for 3h. The complexes were fully characterized using NMR, IR, MS and elemental analysis. Their octahedral geometry with bidentate NO ligand was confirmed by X-ray diffraction analysis. Antiproliferative effect was determined by MTT assay and only the complex with pyridine-2-carboxylic acid (1) showed dose-dependent cytotoxic potential, particularly toward triple-negative breast adenocarcinoma cells MDA-MB-231 with IC50 68.90 ± 1.73 µM and pancreatic adenocarcinoma cells PANC-1 with IC50 69.8 ± 2.3 µM. Drug combination studies in PANC-1 cells with 1 and Verapamil hydrochloride (VRP) showed slight arrest of cell cycle in the S phase and also it increase its antiproliferative potential to IC50 51.4 ± 2.8 μM. Part of the research included a depletion of the glutathione (GSH) level by L-buthionine-sulfoximine (L-BSO) at sub-toxic concentrations (100 μM) in PANC-1 cells which caused an increase of activity of 1 to the IC50 57.67 ± 6.51 μM.

AB  - Ruthenium complexes are of significant interest in the treatment of malignancies. Ru(II)
complexes with N-alkylphenothiazines (chlorpromazine, trifluoperazine, and thioridazine)
were used in the study of possible apoptosis pathways in K562 cells.
Spectrophotometrically extracellular LDH was quantified and immunochemical expression
of COX-2, t-JNK, p-JNK and -actin after SDS electrophoresis was determined. The
Ru(II) complex with trifluoperazine at a concentration of 10 μM reduced t-JNK
expression, inhibited COX-2 by about 42%, significantly increased the amount of
extracellular LDH compared to the untreated K562 cells and thus confirmed apoptosis.

AB  - Two non-steroidal antiinflammatory drugs indomethacin and mefenamic acid were coordinated to Ru(II)-arenes to afford four new complexes. The cytotoxic activities of the ligands and ruthenium complexes were tested in three human cancer cell lines (K562, A549, MDA-MB-231) and non-tumour human fetal lung fibroblast cells (MRC-5) by MTT assay. Cytotoxicity studies revealed that indomethacin Ru(II)-arene complexes 1 and 3 displayed good cytotoxicity and apparent cytoselective profiles. The IC50 values obtained in leukemia K562 cells were comparable to those of cisplatin (10.3 mu M (CDDP), 11.9 mu M (1) and 13.2 mu M (3)). Flow cytometric analysis of 1 and 3 in triple-negative breast cancer MDA-MB-231 cells revealed an interesting mechanism of action. At IC50 concentrations, 1 and 3 arrested cell cycle progression in S phase and caused rapid accumulation of cells in sub-G1 phase (up to 48%), while Annexin V-FITC/PI staining showed simultaneous occurrence of apoptotic and necrotic cell populations at approximately similar levels of 20%. Measurement of reactive oxygen species (ROS) production by DCFH-DA staining confirmed the potential of 1 and 3 to increase ROS even more than cisplatin. The interaction of the complexes with serum albumins showed their potential ability to bind tightly and reversibly to albumins. The affinity of the complexes to calf-thymus DNA was investigated by UV-vis spectroscopy, viscosity measurements and fluorescence emission spectroscopy for competitive studies of the complexes with ethidium bromide, revealing that their interaction probably occurs via intercalation. Taken together, the results strongly suggest the potential of complexes 1 and 3 to alter cell cycle progression and cause DNA-damage by means of direct DNA-binding or indirectly by ROS production.

AB  - Phenothiazines are a large group of heterocyclic, aromatic molecules with nitrogen and sulphur between two benzene rings. Their derivatives, N-alkylphenothiazines have substituent on heterocyclic nitrogen atom which gives them different properties. Also, a series of these molecules have substitution on carbon atom at place 2 of phenothiazine benzene ring. Alkylphenothiazines contain aminoalkyl substituent and their alkyl, acyl and sulphonil derivatives, as well as monocyclic and bicyclic heterocycles attached at thiazine nitrogen atom or directly linked to benzene ring. The N-alkylphenothiazines have been known as antipsychotic drugs, but they also possess antibacterial, antifungal, anticancer activity, and ability to react with macromolecules and to coordinate to the metals. Metal complexes with N-alkylphenothiazines are biological active compounds with different antimicrobial activities and cytotoxic effect against tumor cell lines. The large field of application of N-alkylphenothiazines is very attractive in terms of synthesis of new related derivatives, metal complexes, studying their properties and applications. This article presents a review of the literature and a contemporary view at N-alkylphenothiazines - their synthesis and application, as well as their metal complexes which have promising biological effects.

AB  - The purpose of the present study was to investigate and compare the effects of two ruthenium complexes with trifl uoperazine on acethylcholinesterase enzyme activity and lactate dehydrogenase levels in vivo under physiological conditions in rats blood. Complexes 1 and 2 showed positive effects on acethylcholinesterase at all doses and did not disturb its normal activity. Total LDH activity was inhibited in the presence of both complexes, but Ru(II) complexes showed different effects on the activity of LDH isoenzymes. The activities of LDH1 and LDH2 isoenzymes were decreased in all applied doses of the complex 2, while the activity of LDH2 reduced using complex 1 in the same doses. Results of the present study suggest the neuro-and cardio protective potential of oral administration of complexes 1 and 2, as non-toxic compounds under physiological conditions. These protective effects are the result of their potent antioxidant activity.
AB  - Cilj ovog rada je da se ispitaju i uporede efekti dva kompleksa rutenijuma sa trifluoperazinom na aktivnost enzima acetilholinesteraze i laktat-dehidrogenase in vivo pod fiziološkim uslovima u krvi pacova. Kompleksi 1 i 2 pokazali su pozitivan efekat na aktivnost acetiholinesteraze u svim primenjenim dozama. Ukupna aktivnost LDH je inhibirana u prisustvu oba kompleksa, ali kompleksi Ru(II) pokazuju različite rezultate na izoenzimske oblike ovog enzima. Aktivnosti izoenzima LDH1 i LDH2 su smanjene u svim primenjenim dozama kompleksa 2, dok kompleks 1 smanjuje aktivnost samo izoenzima LDH2 u tim istim koncentracijama. Rezultati prikazanog istraživanja ukazuju na neuro - i kardio zaštitni potencijal oralne primene kompleksa 1 i 2, kao netoksičnih jedinjenja pod fiziološkim uslovima, indukovano preko njihovog snažnog antioksidativnog efekta.

AB  - Two new platinum(IV) complexes (1, trifluoperazinehydrochloride-aquapentachloridoplatinate(IV) and 2, chlorpromazine-chlorpromazinehydrochloridepentachloridoplatinate(IV)) were synthesized in the reaction of K-2[PtCl6] with trifluoperazine dihydrochloride (TF center dot 2HCl) or chlorpromazine hydrochloride (CP center dot HCl). The complexes were characterized by elemental analysis, molar conductivity measurement, and spectral (IR, H-1, C-13, 2D H-1-C-13 heteronuclear correlation spectra, Pt-195 NMR, and MS) methods. Outer-coordination sphere was proposed for 1; while in 2, the ligand was coordinated to the metal. The complexes exhibit antibacterial effect on strains of Bacillus subtilis, Bacillus cereus, Bacillus pumilus, and methicillin-resistant Staphylococci as Gram-positive bacteria and an Escherichia coli as Gram-negative bacteria, as well as the reference strains.

AB  - Three new ruthenium(II) complexes 1-3 containing N-alkylphenothiazine molecules were synthesized by reaction of [RuCl2(eta(6)-P-cymene)](2) with chlorpromazine hydrochloride (1), trifluoperazine dihydrochloride (2) or thioridazine hydrochloride (3). The compounds of the general formula L[RuCl3(eta(6)-p-cymene)] were characterized by elemental analysis and spectroscopic methods (FT-IR, UV-Vis, H-1 and C-13 NMR). Complex 2 was structurally characterized by single crystal X-ray diffraction. In vitro cytotoxic activity of complexes 1-3 were assayed in four human carcinoma cell lines MCF-7, MDA-MB-453 (breast carcinoma), SW-480 (colon carcinoma) and IM9 (myeloma multiple cells). The highest cytotoxicity (12.1  lt = IC50  lt = 17.3 mu M) and induced a total (SW-480) or almost total cell death (MCF-7. MDA-MB-453) at 25 mu M in 48 h of treatment were observed for complex 2. The influence of three different doses (0.4, 4.5 and 90.4 mu M/kg bw) of complex 2 on activities of antioxidants enzymes (superoxide dismutase (SOD) and catalase (CAT)) and lactate dehydrogenase (LDH) were investigated under physiological conditions. The effects on nitrite production (NO2-) and level of erythrocytes malondialdehyde (MDA) in rats blood were evaluated, too. (C) 2011 Elsevier Masson SAS. All rights reserved.

AB  - Three new complexes of the general formula L[RuCl(3)(DMSO)(3)] (1-3), where L = chlorpromazine hydrochloride, trifluoroperazine dihydrochloride or thioridazine hydrochloride, were prepared and characterized by elemental analysis and spectroscopic methods (FT-IR, UV-Vis, (1)H NMR and (13)C NMR). In addition, the crystal structure of the complex 2 containing trifluoroperazine dihydrochloride was solved by single crystal X-ray diffraction. The complex crystallizes in the monoclinic system, space group P2(1)/n, with a = 10.4935(7) angstrom, b = 18.6836(12) angstrom, c = 19.9250(13) angstrom, beta = 98.448(2)degrees, V = 3864.0(4) angstrom(3). The structure was refined to the agreement factors of R = 4.79%, R(w) = 11.23%. The effect of three different doses (0.4, 4.5 and 90.4 mu M/kg bw) of complex 2 on superoxide dismutase (SOD) and catalase (CAT) activity was investigated under physiological conditions. Influence on nitrite production (NO(2)(-)) and the level of erythrocytes malondialdehyde (MDA) in rats blood was also evaluated. Complex 2 did not affect the CAT enzyme activity in vivo and did not cause the hydroxyl radicals production. In the 0.4 and 4.5 mu M/kg bw doses it showed almost the same or lower SOD activity and nitrite levels, while the dose of 90.4 mu M/kg bw significantly increased these parameters. Finally, the cytotoxicity of complexes were assayed in four human carcinoma cell lines MCF-7, MDA-MB-453 (breast carcinoma), SW-480 (colon adenocarcinoma) and IM9 (myeloma multiple cells). Antiproliferative activity in vitro with low IC(50) during 48 h of treatment was observed. (C) 2010 Elsevier Masson SAS. All rights reserved.
