-
, (2012/07/13)
The present invention relates to quinolinium antiinfective agents in which the qunolinium nucleus is fused to an indole ring or the qunolinium nucleus is linked to a cyclic structure through an opened indole or a benzothiophene or benzofuran ring. The compound is further substituted with various substituent groups. The compounds are represented by formula (I), (II) and (III): Pharmaceutical compositions and methods of use are also included.

Previous studies on the indoloquinoline alkaloid, cryptolepine (2), revealed that it has antii-nfective properties among other activities. Using Structure-activity relationship (SAR) techniques, several ring-opened analogs of cryptolepine (3-phenylaminopyridinium and 3-phenylaminoquinolinium derivatives) were designed to improve the potency and lower the cytotoxicity shown by several of the precursor agents. Results indicate that these ring-opened analogs constitute new anti-infective agents with over a 100-fold potency and several fold lower cytotoxicity than cryptolepine from which they are derived.

experimental part, p. 2378 - 2385 (2011/06/22)
Previous studies have indicated that the δ-carboline (2) ring system derived from the natural product cryptolepine (1) may represent a pharmacophore for anti-infective activity. This paper describes the design and synthesis of a small library of substitut
