Triorganotin(IV) complexes with o-substituted arylhydroxamates: Synthesis, spectroscopic characterization, X-ray structures and in vitro cytotoxic activities
摘要:
Six new triorganotin(IV) complexes with six different RN-2-X-benzohydroxamic acid ligands having general formula R'C(O)N(RN)OH (R' = alkyl/aryl; RN = alkyl/aryl or H), (X = -I, -NO2, -OCH3, -Br and R = -CH3, -C6H5 and -C6H4-CH3), were prepared by condensation method with the respective organotin(IV) chlorides using a stoichiometric ratio of 1:1. The bonding and coordination behaviour of these complexes were investigated on the basis of FT-IR, multinuclear H-1, C-13 and Sn-119 NMR spectroscopies. Complexes (1) and (3) crystallize in the orthorhombic P2(1)2(1)2(1) space group and complex (2) crystallizes in the triclinic P-1 space group whereas complex (4) crystallizes in the monoclinic P2(1)/c space group. The tested triphenyltin(IV) complexes showed significant cytotoxicities, higher than doxorubicin toward K-562, Jurkat, HepG2 and L929 cells. (C) 2014 Elsevier B.V. All rights reserved.
