The invention discloses a 2-oxopropionic acid p-methoxybenzoyl hydrazone di(2,4-dichlorobenzyl) tin complex, which is a complex having the structural formula (I) as shown in the specification. In the structural formula (I), R is 2,4-dichlorobenzyl. The invention also discloses a preparation method of the 2-oxopropionic acid p-methoxybenzoyl hydrazone di(2,4-dichlorobenzyl) tin complex and application of the complex in the preparation of an anti-cancer drug.

Description

technical field [0001] The invention relates to a 2-carbonylpropionic acid p-methoxybenzoylhydrazone bis(2,4-dichlorobenzyl)tin complex and a preparation method thereof, and the 2-carbonylpropionic acid p-methoxybenzyl Application of acylhydrazone bis(2,4-dichlorobenzyl)tin complex in the preparation of anticancer drugs. 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 fo...
