Abstract:
[reaction: see text] (1S,2S,3S,4R,5R)-4-amino-5-(hydroxymethyl)cyclopentane-1,2,3-triol 1 is prepared stereoselectively from D-lyxose and displays anomer-selective inhibition for beta-galactosidase (Ki = 3.0 x 10(-6) M) and beta-glucosidase (Ki = 1.5 x 10(-7) M), over alpha-galactosidase (Ki = 2.3 x 10(-5) M) and alpha-glucosidase (IC50 = 1.0 x 10(-4) M). There is no observable cross-reactivity with alpha-mannosidase, beta-mannosidase, or alpha-L-fucosidase.
