Abstrakt: The glucuronic acid analogue of 1-deoxynojirimycin, 2( S)-carboxy-3( R), 4( R), 5( S)-trihydroxypiperidine, recently isolated from seeds of Baphia racemosa, is a novel specific inhibitor of human liver β-D-glucuronidase and α-L-iduronidase. No other glycosidases are inhibited. The inhibition of β-D-glucuronidase is competitive, with a Kiof 8 × 10 −5M and is pH-dependent. This inhibitor may be useful to induce a mucopolysaccharidosis or to investigate the function of microsomal β-D-glucoronidase.
