Abstract
In vitro inhibition studies with beta-glucuronidase from purified E. c oli and mouse intestinal contents indicated that the polymer, poly(vin ylbenzyl D-glucaro(1,4)lactonate, is an effective beta-glucuronidase i nhibitor. Purified E. coli beta-glucuronidase was inhibited by 99.6% w ith 177 mM D-glucaro(1,4)lactone using the polymer-inhibitor. Similarl y, 95% inhibition of beta-glucuronidase activity of mouse intestinal c ontents was obtained with 177 mM and 50% inhibition was obtained with 31.5 mM D-glucaro(1,4)lactone based on the modified polymer. The struc tural requirements of an effective beta glucuronidase inhibitor based on the structure of the polymer-inhibitor are also discussed.
