Antituberculosis and cytotoxic activities of triorganotin(IV) complexes

Five triorganotin(IV) (1–5) complexes of cinnamic acid, (Z)-2-acetamido-3-phenylacrylic acid, 3-methylbut-2-enoic acid, and 2,2-diphenylacetic acid have been synthesized and characterized by 1H–13C–119Sn NMR, UV, and IR. The spectroscopic investigation demonstrated that the carboxylate group acts as a monodentate ligand in triorganotin(IV) compounds. Five triorganotin(IV) complexes were screened against the log phase culture of Mycobacterium tuberculosis H37Rv by colorimetric method using XTT dye as growth indicator. The MICs were found to be 0.08 and 1.25 μg/mL.
