The 2-oxo-2-phenylacetic acid aroyl hydrazine dibutyltin complex (1)has been synthesized via the reaction of the 2-oxo-2-phenylacetic acid aroyl hydrazine with the dibutyltin oxide.The complex (1 )has been characterized by FT-IR,1 H NMR,13 C NMR spectra,elemental analysis,thermal analysis and X-ray diffraction.The anticancer activity of the complex (1)a-gainst five species of cancer cell which are Hela,MCF7,HepG2,Colo205,NCI-H460 and Human normal cell line HEK293, HL7702 were tested respectively.The interaction between complex and Calf Thymus DNA were studied by EB fluorescent probe,the result...
