Synthesis and antihepatotoxicity of some Wuweizisu analogues

Wu,Chen,Chang,Chen,Lee

, p. 353 - 358 (2007/10/02)

A preparation of dimethyl 4,4'-dimethoxy-5,6,5',6'-dimethylenedioxybiphenyl-2,2'-dicarboxylate (VII) was readily achieved. It provided the advantages of specificity, simplicity, and efficiency in reactions. 6-Phenyl-3,9-dimethoxy-1,2-methylenedioxy-10,11-methylenedioxy-6,7- dihydro-5H-dibenz(c, e)azepin (X) was successfully synthesized from VII (DDB) and its liver-protective property proved to be more effective than DDB and silymarin in the in vitro test of carbon tetrachloride-induced damage of primary cultured rat hepatocytes.
