Therapeutic potential of coumestan Pks13 inhibitors for tuberculosis.

ABSTRACT: Polyketide synthase 13 (Pks13) is an important enzyme found in Mycobacterium tuberculosis (M. tuberculosis) that condenses two fatty acyl chains to produce α-alkyl β-ketoesters, which in turn serve as the precursors for the synthesis of mycolic acids that are essential building blocks for maintaining the cell wall integrity of M. tuberculosis Coumestan derivatives have recently been identified in our group as a new chemotype that exert their antitubercular effects via targeting of Pks13. These compounds were active on both drug-susceptible and drug-resistant strains of M. tuberculosis as well as showing low cytotoxicity to healthy cells and a promising selectivity profile. No cross-resistance was found between the coumestan derivatives and first-line TB drugs. H
