Synthesis and cytotoxicity of novel bisellipticines and bisisoellipticines

A series of bis-ellipticines 7-9 and bis-isoellipticines 10-12 tethered through the indole nitrogen was synthesized and screened for antitumor cytotoxicity in the L-1210 murine leukemia assay. Activity was only displayed by 1,10-bis(6-ellipticinyl)-?-decane (8).

Synthesis and in vitro antitumor activity of novel 2-alkyl-5- methoxycarbonyl-11-methyl-6H-pyrido[4,3-b]carbazol-2-ium and 2-alkylellipticin-2-ium chloride derivatives

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.

Ellipticines and 9-acridinylamines as inhibitors of d-alanine:d-alanine ligase

d-Alanine:d-alanine ligase (Ddl), an intracellular bacterial enzyme essential for cell wall biosynthesis, is an attractive target for development of novel antimicrobial drugs. This study focused on an extensive evaluation of two families of Ddl inhibitors encountered in our previous research. New members of both families were obtained through similarity search and synthesis. Ellipticines and 9-acridinylamines were both found to possess inhibitory activity against Ddl from Escherichia coli and antimicrobial activity against E. coli and Staphylococcus aureus. Ellipticines with a quaternary methylpyridinium moiety were the most potent among all studied compounds, with MIC values as low as 2 mg/L in strains with intact efflux mechanisms. Antimicrobial activity of the studied compounds was connected to membrane damage, making their development as antibacterial drug candidates unlikely unless analogues devoid of this nonspecific effect can be discovered.

SYNTHESIS OF ELLIPTICINE

The 6H-pyridocarbazole system is efficiently synthesized by intramolecular attack of an ester enolate on an unactivated pyridinium salt.
