AB  - Two novel triphenyltin(IV) compounds, [Ph(3)SnL1] (L1 = 2-(5-(4- fluorobenzylidene)-2,4-dioxotetrahydrothiazole-3-yl)propanoate (1)) and [Ph(3)SnL2] (L2 = 2-(5-(5-methyl-2-furfurylidene)-2,4-dioxotetrahydrothiazole-3-yl)propanoate (2)) were synthesized and characterized by FT-IR, (H-1 and C-13) NMR spectroscopy, mass spectrometry, and elemental microanalysis. The in vitro anticancer activity of the synthesized organotin(IV) compounds was determined against four tumor cell lines: PC-3 (prostate), HT-29 (colon), MCF-7 (breast), and HepG2 (hepatic) using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-12 diphenyltetrazolium bromide) and CV (crystal violet) assays. The IC50 values are found to be in the range from 0.11 to 0.50 mu M. Compound 1 exhibits the highest activity toward PC-3 cells (IC50 = 0.115 +/- 0.009 mu M; CV assay). The tin and platinum uptake in PC-3 cells showed a threefold lower uptake of tin in comparison to platinum (as cisplatin). Together with its higher activity this indicates a much higher cell inhibition potential of the tin compounds (calculated to ca. 50 to 100 times). Morphological analysis suggested that the compounds induce apoptosis in PC-3 cells, and flow cytometry analysis revealed that 1 and 2 induce autophagy as well as NO (nitric oxide) production.

AB  - Triphenyltin(IV) compounds with naphthoquinone derivatives containing N-acetylcysteine, N-acetyl-S-(3,4-dihydro-3,4-dioxo-1-naphthyl)cysteine (1,2-NQC), 1, and N-acetyl-S-(1,4-dihydro-1,4-dioxo-2-naphthyl)cysteine (1,4-NQC), 2, were synthesized and characterized by elemental microanalysis, IR, multinuclear (H-1, C-13, Sn-119) NMR spectroscopy as well as HR-ESI mass spectrometry. With the aim of in vitro anticancer activity determination of ligand precursors and novel synthesized organotin(IV) compounds against human cervix adenocarcinoma (HeLa), human colon carcinoma (HT-29) and melanoma carcinoma cell line (B16F10), MTT colorimetric assay method was applied. The results indicate that synthesized compounds exhibited remarkable antiproliferative activity toward all tested cell lines with IC50 in the range from 0.17 to 0.87 mu M. Complex 1 showed the greatest activity against HT-29 cells, with IC50 value of 0.21 +/- 0.01 mu M, 119 times better than cisplatin, while complex 2 demonstrated the highest activity toward HeLa cells, IC50 = 0.17 +/- 0.01 mu M, which is similar to 26 times better than cisplatin.

AB  - A novel triphenyltin(IV) compound with 1-(4-carboxyphenyl)-3-ethyl-3-methylpyrrolidine-2,5-dione was synthesized and characterized by IR, NMR spectroscopy, mass spectrometry, and elemental analysis. In vitro anticancer activity of ligand precursor and synthesized organotin(IV) compound was determined against tumor cell lines: human adenocarcinoma (HeLa), human myelogenous leukemia (K562), and human breast cancer (MDA-MB-453), using microculture tetrazolium test (MTT) assay. The results indicate that complex exhibited very high antiproliferative activity against all tested cell lines with IC50 values in the range of 0.22 to 0.53 mu M. The highest activity organotin(IV) compound expressed against the HeLa cells (IC50=0.22 +/- 0.04 mu M). The ligand precursor did not show anticancer activity (IC50>200 mu M). Furthermore, fluorescence microscopy analysis of HeLa cells reveal that organotin(IV) complex induced apoptosis as a mode of cell death, which is consistent with the increase of cells in the sub-G1 phase.

AB  - Aims: Platinum(II) and platinum(IV) complexes [PtCln{(S,S)-(i-Am)(2)eddip}] (n = 2, 4: 1, 2, respectively; (S,S)-(i-Am)(2)eddip = O,O'-diisoamyl-(S,S)-ethylenediamine-N,N'-di-2-propanoate) were synthesized and characterized by elemental analysis, IR, H-1 and C-13 NMR spectroscopy and mass spectrometry. Method: Quantum chemical calculations were used to predict formed isomers of 1 and 2. Furthermore, reduction of 2 with ascorbic acid was followed by time-dependant C-13 NMR spectroscopy in order to enable assignation of the formed isomers for complex 1. In vitro cytotoxic activity was determined for 1 and 2 on a panel of five human tumor cell lines derived from cervix adenocarcinoma (HeLa), alveolar basal adenocarcinoma (A549), breast adenocarcinoma (MDA-453), colorectal cancer (LS 174), erythromyeloblastoid leukemia (K562), as well as one non-malignant human lung fibroblast cell line (MRC-5), using MTT assay. Result: Both complexes exhibited high (2 against K562: IC50 = 5.4 mu M), more active than cisplatin, to moderate activity (1). Both complexes caused considerable decrease of cell number in K562 cells in G1, S and G2 phases, concordantly increasing subpopulation in sub-G1 fraction. Morphological analysis of K562 cell death induced by platinum(II/IV) complexes indicate apoptosis.

AB  - Four novel gold(III) complexes of general formulae [AuCl2{(S,S)-R(2)eddl}]PF6 (R(2)eddl = O,O'-dialkyl-(S,S)-ethylenediamine-N,N'-di-2-(4-methyl)pentanoate, R= n-Pr, n-Bu, n-Pe, i-Bu; 1-4, respectively), were synthesized and characterized by elemental analysis, UV/Vis, IR, and NMR spectroscopy, as well as high resolution mass spectrometry. Density functional theory calculations pointed out that (R,R)-N,N'-configuration diastereoisomers were energetically the most favorable. Duo to high cytotoxic activity complex 3 was chosen for stability study in DMSO, no decomposition occurs within 24 h, and for the reaction with ascorbic acid in which was reduced immediately. Additionally, 3 interacts with bovine serum albumin (BSA) as proven by UV/Vis spectroscopy. In vitro antitumor activity was determined against human cervix adenocarcinoma (HeLa), human myelogenous leukemia (K562), and human melanoma (Fem-x) cancer cell lines, as well as against non-cancerous human embryonic lung fibroblast cells MRC-5. The highest activity was observed against K562 cells (IC50: 5.04-6.51 mu M). Selectivity indices showed that these complexes are less toxic than cisplatin. 3 had a similar viability kinetics on HeLa cells as cisplatin. Drug accumulation studies in HeLa cells showed that the total gold uptake increased much faster than that of cisplatin pointing out that 3 more efficiently enters the cells than cisplatin. Furthermore, morphological and cell cycle analysis reveal that gold(III) complexes induced apoptosis in time- and dose-dependent manner.

AB  - Oxidation-reduction properties of eleven gold(III) complexes with (S,S)-R(2)edda-type ligands was studied by cyclic and differential pulse voltammetry in DMSO. Series I: [AuCl2{(S,S)-R(2)eddip}]PF6, (S,S)-eddip = (S,S)-ethylenediamine-N,N'-di-2-propanoate, R = n-butyl, n-pentyl, isobutyl, isoamyl, cyclopentyl, 1-5; II: [AuCl2{(S,S)-R(2)eddch}]PF6, (S,S)-eddch = (S,S)-ethylenediamine-N,N'-di-2-(3-cyclohexyl)propanoate, R = methyl, ethyl, n-propyl, n-butyl, isobutyl, isoamyl, 6-11. Voltammograms in DMSO showed two successive irreversible reduction steps, where Au-I species were the final reduction product. Reduction potential values are in range from 116 to 156 mV (Ep(1)) and -520 to -572 mV (Ep(2)) for Series I and from 148 to 228 mV (Ep(1)) and -569 to -638 mV (Ep(2)) for Series II. In general, slightly easier reduction of complexes belonging to Series I (higher cytotoxicity) could be due to less steric hindrance around the gold center. Reduction potentials and anticancer activity are not in correlation.

AB  - A novel gold(III) complex, [AuCl2{(S,S)-Et(2)eddl}]PF6, ((S,S)-Et(2)eddl = O,O-diethyl ester of ethylenediamine-N,N-di-2-(4-methyl)pentanoic acid) was synthesized and characterized by IR, 1D (H-1 and C-13), and 2D (H,H-COSY and H,H-NOESY) NMR spectroscopy, mass spectrometry, and elemental analysis. Density functional theory calculations confirmed that (R,R)-N,N diastereoisomer was energetically the most stable isomer. In vitro antitumor action of ligand precursor [(S,S)-H(2)Et(2)eddl]Cl-2 and corresponding gold(III) complex was determined against tumor cell lines: human adenocarcinoma (HeLa), human colon carcinoma (LS174), human breast cancer (MCF7), non-small cell lung carcinoma cell line (A549), and non-cancerous cell line human embryonic lung fibroblast (MRC-5) using microculture tetrazolium test (MTT) assay. The results indicate that both ligand precursor and gold(III) complex have showed very good to moderate cytotoxic activity against all tested malignant cell lines. The highest activity was expressed by [AuCl2{(S,S)-Et(2)eddl}]PF6 against the LS174 cells, with IC50 value of 7.4 +/- 1.2 mu M.

DFT calculations indicate that in case of 1-4, the most stable isomers are with (S,S)- and (R,S)-configuration of nitrogen atoms, but for complex 6 (R,R)- and (R,S)-N,N'-configured isomers. Furthermore, complex 5 was obtained as (S,S)-N,N' configured isomer. Cytotoxicity study was performed against human cervical adenocarcinoma (HeLa), human alveolar basal adenocarcinoma (A549) and non-cancerous human fetal lung fibroblast (MRC-5) cell lines using colorimetric MTT assay. From the investigated palladium(II) complexes 2, 3 and 5 exhibited highest cytotoxic potential against HeLa (IC50: 28.5 +/- 3.9, 29.5 +/- 1.3 and 34.3 +/- 3.2, respectively).

AB  - A novel (S,S)-R(2)eddip ester, O,O'-diisopentyl-(S,S)-ethylenediamine-N,N'-di-2-propanoate dihydrochloride (1) was synthesized and characterized by IR, H-1- and C-13-NMR spectroscopy, mass spectroscopy and elemental analysis. In vitro antitumor action of 1, and two more R(2)eddip esters, dialkyl (S,S)-ethylenediamine-N,N'-di-2-propanoate dihydrochlorides, obtained before (alkyl = n-Bu or n-Pe, 2 and 3, respectively), was determined against cervix adenocarcinoma (HeLa), human melanoma (Fem-x), human chronic myelogenous leukemia (K562) cells, and a non-cancerous cell line human embryonic lung fibroblast (MRC-5), using the microculture tetrazolium test MTT assay. Esters 1-3 showed higher cytotoxicity and better selectivity in comparison to cisplatin, used as reference compound. The highest activity was expressed by 1, with IC50(Fem-x) value of 1.51 +/- 0.09 mu M.

AB  - Three novel complexes of platinum(II) with R(2)edda bidentate ligands [PtCl2(R(2)edda)] (R = Me, Et, n-Pr; edda = ethylenediamine-N,N'-diacetate; 1-3), are synthesized and characterized by IR and NMR spectroscopy and elemental analysis. All complexes exist in three stereoisomeric forms (R,R), (S,S) and (R,S)(S,R). In addition crystal structure of one platinum(IV) complex [PtCl4((n-Pr)(2)edda)], 4, is presented. Furthermore, in order to assign stereoisomers of 1-3, a reduction of racemic [PtCl4(Et(2)edda)] by ascorbic acid to [PtCl2(Et(2)edda)] (2) was performed and analyzed by H-1 NMR. Time-depending H-1 NMR spectroscopic experiments were implemented to study the stability of ethylenediamine-N,N'-diacetate diesters. Finally, the in vitro cytotoxic activity of complexes 1-3 was studied on 11 tumor cell lines, 518A2 (melanoma), 8505C (human thyroid carcinoma), A253 (head and neck tumor), A431 (cervix), A549 (lung), A2780 (ovarian), MCF-7 (breast) and HT-29, HCT-8, DLD-1, SW1736 (all colon) by the SRB colorimetric assay method. Complex 3 showed the highest action against ovarian (A2780) cells with an IC50 value 51 +/- 1 mu M.

AB  - Six novel gold(III) complexes containing O,O'-dialkyl-(S,S)-ethylenediamine-N,N'-di-2-(3-cyclohexyl)propanoate ([AuCl2{(S,S)-R(2)eddch}]PF6, R = Me, Et, n-Pr, n-Bu, i-Bu, i-Am; 1-6, respectively) were synthesized and characterized by elemental analysis, UV/Visible, IR and NMR spectroscopy, mass spectrometry and differential pulse voltammetry. Density functional theory (DFT) calculations confirmed that diastereoisomer with the N,N' atoms configured (S,S) was the most stable. In vitro antiproliferative activity was determined against human cervix adenocarcinoma HeLa and human myelogenous leukemia K562 tumor cell lines, as well as against rested and stimulated normal immunocompetent human peripheral blood mononuclear cells (PBMC) using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Complex 6 expressed the highest activity against K562 cells (IC50 = 3.8 +/- 0.5 mu M). Apoptosis, seen as condensation of HeLa cell nuclei was the mode of cell death induced by complexes 2-6. Complexes 3-6 induced death of K562 cells inhibiting cell entry in mitosis.
