Synthesis, Characterization, and In Vitro Cytotoxicity of Triorganotin 3,5-Di-tert-butyl-4-hydroxybenzoates
摘要:
The triorganotin 3,5-di-tert-butyl-4-hydroxybenzoates, 3,5-(t-Bu)(2)-4-HO-C6H2COOSnR3 (R = c-C6H11, 1; C6H5, 2; C6H5CH2, 3; C6H5C(CH3)(2)CH2, 4), have been synthesized and characterized by elemental analysis, IR, and H-1 and C-13 NMR spectra. The crystal structures of 1 and 4 have been determined by X-ray single crystal diffraction and show that the tin atom possesses a distorted tetrahedral geometry. Intermolecular O-H center dot center dot center dot O hydrogen bond in 1 connects neighboring molecules into a cyclic tetramer. The in vitro cytotoxicity of the compounds against the human tumor cell lines A549 was found to be higher than that of cis-platin used clinically.
