Synthesis of potent β-D-glucocerebrosidase inhibitors: N-alkyl-β-valienamines
摘要:
Six homologous derivatives (N-butyl 3a, hexyl 3b, octyl 3c, decyl 3d, tetradecyl 3e and stearyl 3f) of beta-valienamine were synthesized. All have been shown to be potent and specific inhibitors of beta-glucocerebrosidase, and to have no potency against glucosylceramide synthase (mouse liver microsomes). Among them, the N-octyl derivative possesses the strongest activity (IC50 3 x 10(-8) M), being almost 10-fold more potent compared to the unsaturated 5a-carba-glucosylceramide 1. Compounds 3b and 3e are also moderate inhibitors of alpha-glucosidase (Baker's yeast). Copyright (C) 1996 Elsevier Science Ltd

This minireview covers synthetic methods towards carbasugar-containing non-glycosidicallylinked pseudodisaccharides or higher pseudooligosaccharides. Carbocyclic pyranose mimetics (saturated or unsaturated between C-5 and C-5a) are linked by ether, thioether or amine bridges to carbohydrates or other carbasugars.
Imino-linked carbocyclic analogues (E)- and (Z)-2 of glucosylceramide 1 have been synthesized and shown to be potent and specific inhibitors against glucocerebrosidase.
