Synthesis of New Organotin(IV) N-methyl-N-benzyl Dithiocarbamate Compounds and Cytotoxicity assessment on Human Lung Carcinoma Cell Line (A549)

Abstract

Using the In-situ method, the successful synthesis of dibutyltin(IV) N-methyl-N-benzyldithiocarbamate (Compound 1) and tricyclohexyltin(IV) N-methyl-N-benzyldithiocarbamate (Compound 2) was achieved. Both compounds were characterized by the CHNS elemental analysis, FTIR, NMR spectroscopies and X-ray crystallography study. The experimental CHNS values demonstrated good congruence with the CHNS’s theoretical values of the suggested formula structures. The key infrared absorbance peaks, νC—N) and νC—N), which were found between 1475–1481 cm–1 and 971–975 cm–1, respectively. The 13C chemical shift of carbon in the NCS2 group was observed in the range of 200.66–202.32 ppm. The crystal structure of Compound 1 shows the anisobidentate’s coordination mode between the central metal of the Sn atom and the dithiocarbamate ligands. Compound 1 and Compound 2 have shown great toxicity effects against carcinoma cells in the human lung (A549) with lower IC50 values of 0.80 µM and 2.77 µM, respectively.
