Bacterial β-glucuronidase in the intestine is involved in the conversion of 7-ethyl-10- hydroxycamptochecin glucuronide (derived from irinotecan) to 7-ethyl-10-hydroxycamptothecin, which causes intestinal bleeding and diarrhea (side effects of anti-cancer drugs). Twelve compounds (1?12) from Polygala tenuifolia were evaluated in terms of β-glucuronidase inhibition in vitro. 4-OBenzoyl- 3′-O-(O-methylsinapoyl) sucrose (C3) was highly inhibitory at low concentrations. C3 (an uncompetitive inhibitor) exhibited a ki value of 13.4 μM; inhibitory activity increased as the substrate concentration rose. Molecular simulation revealed that C3 bound principally to the Gln158?Tyr160 enzyme loop. Thus, C3 will serve as a lead compound for development of new β- glucuronidase inhibitors.
