Abstract
Screening of the ChemDiv molecular library in cholesterol media against Mycobacterium tuberculosis (Mtb) H37Rv strain identified a novel isoxazole thiophene hit as a putative Rv1625c/Cya activator with a promising in vitro activity and good pharmacokinetic properties. Twenty-nine analogs were synthesized to assess the structure–activity relationships (SAR) to further improve potency. The most notable analog was P15, which showed an intramacrophage EC50 = 1.96 µM and exhibited 58.0 % oral bioavailability when it was dosed orally at 20 mg/kg in a mouse pharmacokinetic (PK) study. The overall medicinal chemistry campaign revealed limited SAR that did not support further investigation into this series.
