Twenty-one types of novel ellipticine derivatives and pyridocarbazoles (5-methoxycarbonyl-11-methyl-6H-pyrido[4,3-b]carbazoles) with a nitrosourea moiety, linked by an oxydiethylene unit at the 2 position, were synthesized, and their cytotoxicity against HeLa S-3 cells was evaluated. Some of these new compounds exhibited potent antitumor activity by comparison with that of ellipticine.

9-Hydroxyellipticine (9-hydroxy-5,11-dimethyl-6H-pyrido[4,3-b]carbazole) has been synthesized from ellipticine via a direct regioselective formylation, followed by a Baeyer-Villiger oxidation.

6-Methylellipticine (6) undergoes acylation at the C(9)-position, under Friedel Crafts reaction conditions.The C(9)-formyl compound (8) rearranges to the corresponding hydroxy derivative (9) upon treatment with hydrogen peroxide, in methanol, in the presence of sulphuric acid.The two steps provide a convenient procedure for the specific C(9)-hydroxylation of the ellipticine template.
A NEW APPROACH TO C-9 HYDROXYLATION OF N(6)-SUBSTITUTED ELLIPTICINE
Langendoen, Albert,Koomen, Gerrit-Jan,Pandit, Upendra K.
, p. 91 - 94 (2007/10/02)
6-Methylellipticine is converted to the corresponding 9-hydroxy derivative via a reaction sequence involving selective C-9 formylation followed by a Baeyer-Villiger rearrangement.
9-Acyloxy-5,11-dimethyl-6H-pyrido[4,3-B]carbazoles

, (2008/06/13)
9-Acyloxy-5,11-dimethyl-6H-pyrido[4,3-b]carbazoles of the formula SPC1 Wherein R1 is acyl and R2 is hydrogen or lower alkyl, are described. The end products actively inhibit the growth of transplantable tumors, and are therefore useful as cytostatic agents.
