1,5-DIMETHYL-6H-PYRIDO[4,3-B]CARBAZOLE

This alkaloid has recently been shown to exhibit a marked antineoplastic activity. Administration of 25 or 50 mg/kg intraperitoneally on alternate days or daily until death to mice which had been inoculated with a single intraperitoneal dose of 106 -102 LI2l0 leukemia cells increased the survival time by 89-229 per cent compared with control animals.
Japanese workers have recently reported the synthesis of olivacine by heating indole with 4(1-hydroxyethyl)-3-methoxymethyl-2-methylpyridine in 47 per cent HBr.

ChEBI: Olivacine is a member of carbazoles.
