Studies on DNA interaction of organotin(IV) complexes of meso-tetra(4-sulfonatophenyl)porphine that show cellular activity

Diorgano- and triorganotin(IV) derivatives of meso-tetra-(4-sulfonatophenyl)porphine interact with DNA and the butyl-containing species, known from literature to be endowed with significant cellular activity, are found to noticeably alter the DNA conformation.84
