abstract = "The reaction of 3-methoxyphenylacetic acid (3-MPAH), 4-methoxyphenylacetic acid (4-MPAH), 2,5-
dimethyl-3-furoic acid (DMFUH) or 1,4-benzodioxane-6-carboxylic acid (BZDOH) with triphenyltin(IV)
chloride (1:1) or diphenyltin(IV) dichloride (2:1) in the presence of triethylamine yielded the compounds
[SnPh3(3-MPA)] (1), [SnPh3(4-MPA)] (2), [SnPh3(DMFU)] (3), [SnPh3(BZDO)] (4), [SnPh2(3-MPA)2] (5),
[SnPh2(4-MPA)2] (6), [SnPh2(DMFU)2] (7) and [SnPh2(BZDO)2] (8), respectively. The tetranuclear complex
[{Me2(DMFU)SnOSn(DMFU)Me2}2] (9) was prepared by the reaction of dimethyltin(IV) oxide and 2,5-
dimethyl-3-furoic acid (DMFUH). The molecular structures of 3, 4 and 9, were determined by X-ray diffraction
studies. The cytotoxic activity of the carboxylic acids (3-MPAH, 4-MPAH, BZDOH and DMFUH)
and di (5–8) and triphenyltin(IV) complexes (2–4) was tested against tumor cell lines human adenocarcinoma
HeLa, human myelogenous leukemia K562, human malignant melanoma Fem-x and normal
immunocompetent cells, peripheral blood mononuclear cells PBMC. Triphenyltin(IV) complexes show
higher activities than the diphenyltin(IV) derivatives. The most active compound is [SnPh3(DMFU)] (3)
with IC50 value of 0.15 } 0.01, 0.051 } 0.004, 0.074 } 0.004, 0.20 } 0.01, 0.15 } 0.02 on HeLa, K562, Femx,
rested and stimulated PBMC, respectively, while the most selective are [SnPh2(3-MPA)2] (5),
[SnPh2(DMFU)2] (7) and [SnPh2(BZDO)2] (8). Compounds 3, 5, 7 and 8 present higher activities than cisplatin
in all the tested cells and relative high selectivity especially on K562 cells.",
