The invention further discloses a preparation method and application of the 2-carbonyl-3-phenylpropionic acid salicyloyl hydrazone di-n-butyltin complex in preparation of anti-cancer medicines.

Description

technical field [0001] The invention relates to a 2-carbonyl-3-phenylpropionic acid salicylhydrazone di-n-butyltin complex and a preparation method thereof, and the 2-carbonyl-3-phenylpropionic acid salicylhydrazone di-n-butyltin complex is used in the preparation of anticancer application in medicine. Background technique [0002] Organotin is a class of metal-organic compounds containing Sn-C bonds. Researchers have noticed the in vitro anticancer activity of organotin compounds long ago. Research on the antitumor activity of organotin(IV) compounds dates back to 1929. In 1967, Kanisawa et al. considered that tin chloride was ineffective against primary tumors in mice and rats. But in 1972, Brown discovered that triphenyltin acetate Ph 3 SnOOCCH 3 Can inhibit tumor growth in mice, but triphenyltin chloride does not. From 1972 to 1977, Dutch scholars studied a large number of organotin compounds, but no compounds with further screening value were found. They continue...
