Design, synthesis, and testing of an isoquinoline-3-carboxylic-based novel anti-tumor lead

Bioorg Med Chem Lett. 2015 Oct 15;25(20):4434-6. doi: 10.1016/j.bmcl.2015.09.014. Epub 2015 Sep 7.

Abstract

Compound 6, a novel isoquinoline comprising two isoquinoline-3-carboxylic acids and a benzoic acid conjugated together using tris(2-aminoethyl)amine, was synthesized and tested for anti-tumor activity. In vivo evaluations found 6 to be well tolerated, of high therapeutic efficacy and of low systemic toxicity, at effective doses. The results suggest 6 to be a promising lead for future study, and the use of multiple isoquinoline-3-carboxylic acid moieties as pharmacophores in the same molecule to be a useful strategy for the design of anti-tumor drugs.

Keywords: Anti-tumor; Benzoic acid; Isoquinoline-3-carboxylic acid; Multiple pharmacophores; Tris(2-aminoethyl)amine.
