Triphenyltin(IV) compounds with naphthoquinone derivatives containing N-acetylcysteine, N-acetyl-S-(1,2-dion-4-naphthyl)cysteine (1,2-NQC), 1, and N-acetyl-S-(1,4-dion-2-naphthyl)cysteine (1,4-NQC), 2, were synthesized and characterized by elemental microanalysis, IR, multinuclear (1H, 13C, 119Sn) 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 of 0.17 to 0.87 μM. Complex 1 showed the greatest activity against HT-29 cells, with IC50 value of 0.21 ± 0.01 μM, 119 times better than cisplatin, while complex 2 demonstrated the highest activity toward HeLa cells, IC50 = 0.17 ± 0.01 μM, which is ~26 times better than cisplatin.
