Synthesis and Biological Properties of 3-(Dihydroxybenzoyloxy)methyl- and 3-(Diacetoxybenzoyloxy)methyl-7α-chlorocephalosporanate Sulfones
2000
We describe the synthesis of tert-butyl esters of 3-(2-hydroxybenzoyloxy)methyl-, 3-(dihydroxybenzoyloxy)methyl-, and 3-(diacetoxybenzoyloxy)methyl-7α-chlorocephalosporanic acid sulfones by reaction of tert-butyl ester of 3-bromomethyl-7α-chlorocephalosporanic acid sulfone with salts of hydroxy- and acetoxy-substituted benzoic acids. We have investigated the elastase-inhibiting properties of the compounds obtained and also their in vitro cytotoxic activity.
