| Abstract: Three triorganotin (4R)-3-[[(2S)-5-oxo-2-pyrrolidinyl]carbonyl]-4-thiazolidinecarboxylates, R3SnL (1, R=c-C6H11, a; C6H5, b; C6H5C(CH3)2CH2, c), have been synthesized by the reaction of triorganotin hydroxide with (4R)-3-[[(2S)-5-oxo-2-pyrrolidinyl]carbonyl]-4-thiazolidinecarboxylic acid (HL) and characterized by means of elemental analysis, IR, 1H NMR spectra and X-ray single crystal diffraction. The crystal of 1a belongs to orthorhombic space group P212121, and the crystal of 1b belongs to monoclinic space group P21 Compounds 1a and 1b both possess a trans-C3SnO2 trigonal bipyramidal geometry with the axial positions occupied by the carboxylate oxygen and the lactam oxygen of pyroglutamyl of an adjacent molecule and form a one-dimensional right-handed helix. The compounds 1a and 1b have potent in vitro anti-tumor activity against two human tumor cell lines, Colo205 and Bcap37. The activity order is 1b>1a. CCDC: 837609, HL; 837610, 1a; 837611, 1b. | |
