title: [Induction of rat hepatic mono-oxygenases by ellipticine: formation of cytochrome p448. Hydroxylating activity].
abstract: Ellipticine is able to induce cytochrome P448 synthesis in Rat liver microsomes which converts the drug into 9-hydroxy derivative, with a higher rate than microsomal cytochrome P450 of non-treated or phenobarbital induced Rats. In vivo, ellipticine is also transformed into a second hydroxylated product on the indole aromatic ring.
