General description
An orally bioavailable trisubstituted thiourea compound that acts as a potent, uncompetitive and reversible inhibitor of bacterial β-glucuronidase activity (IC50 = 283 nM; kcat/Km = 0.0987 s-1µM-1; Ki = 164 nM in vitro assays against E coli β-glucuronidase; EC50 = 17.7 nM in β-glucuronidase expressing HB101 cells) with excellent selectivity over mammalian β-glucuronidases. Shown to directly target the 17-residue (360-376) loop structure that protects the active site of E coli β-glucuronidase and alter its conformation. Displays negligible cytotoxicity toward both bacterial and mammalian epithelial cells (>>100 µM for HCT116, Caco-2 and CMT93 colon cancer cells) and offers protection against CPT-11 (50 mg/kg, i.p., s.i.d. for 9 days)-induced toxicity in mice (10 µg, p.o., b.i.d).
