Twelve dinuclear diorganotin(IV) complexes based on bis-tridentate Schiff bases and R2SnO (IV) oxides (R = Me, n-Bu, Ph) were synthesized by multicomponent reactions in moderate yields. The complexes were characterized by common spectroscopic techniques such as FT-IR, mass spectrometry and NMR (H-1, C-13 and Sn-119) analysis. X-ray diffraction analysis was done for compounds 1c, 1d, 1f, 1j and 1l. Sn-119 NMR spectra showed signals at delta = 135-145, 175-185 and 319-323 ppm for Me, n-Bu and Ph derivatives respectively, indicating the pentacoordinate geometry for fin atoms. In solid state, for methyl derivatives (1c, 1d) a distorted octahedral geometry for fin atoms was observed owing the presence of Sn center dot center dot center dot O intermolecular interactions.

The present invention generally relates to anticancer agents and methods of treating cancer. The anticancer agents described herein comprise a bisphenol core and generally act as topoisomerase II inhibitors, though their anticancer activity may be related to other mechanisms as well. The bisphenols discussed therein may also protect certain cells against detrimental effects of topoisomerase II poisons.
