Cyclopalladated and cycloplatinated benzophenone imines: Antitumor, antibacterial and antioxidant activities, DNA interaction and cathepsin B inhibition. J Inorg Biochem. 2014 Jul 15;140C:80-88 Authors: Albert J, D'Andrea L, Granell J, Pla-Vilanova P, Quirante J, Khosa MK, Calvis C, Messeguer R, Badía J, Baldomà L, Font-Bardia M, Calvet T Abstract The antitumor, antibacterial and antioxidant activity, DNA interaction and cathepsin B inhibition of cyclo-ortho-palladated and -platinated compounds [Pd(C,N)]2(μ-X)2 [X=OAc (1), X=Cl (2)] and trans-N,P-[M(C,N)X(PPh3)] [M=Pd, X=OAc (3), M=Pd, X=Cl (4), M=Pt, X=Cl (5)] are discussed [(C,N)=cyclo-ortho-metallated benzophenone imine]. The cytotoxicity of compound 5 has been evaluated towards human breast (MDA-MB-231 and MCF-7) and colon (HCT-116) cancer cell lines and that of compounds 1-4 towards the HCT-116 human colon cancer cell line. These cytotoxicities have been compared with those previously reported for compounds 1-4 towards MDA-MB-231 and MCF-7 cancer cell lines. Compound 3 and 4 were approximately four times more active than cisplatin against the MDA-MB-231 and MCF-7 cancer cell lines, and compound 5, was approximately four times more potent than cisplatin against the HCT-116 cancer cell line. The antibacterial activity of compounds 1-5 was in between the ranges of activity of the commercial antibiotic compounds cefixime and roxithromycin. Complexes 1-2 and 4-5 presented also ant...
