Synthesis and evaluation of glucocerebrosidase inhibitory activity of anhydro deoxyinositols from (+)-epi-and(−)-vibo-quercitols

Twelve 1,2- and 2,3-anhydro-1,2,3,4,5-cyclohexanepentols were synthesized from (+)-epi-and (−)-vibo-quercitols, readily available by bioconversion of myo-inositol, and assayed for inhibitory activity against glucocerebrosidase (mouse liver). Among them 1 -1,2-anhydro-1,2,4/3,5-cyclohexanepentol, the 3-deoxy derivative of the irreversible inhibitor conduritol B epoxide (CBE), has been demonstrated to be a highly potent and specific inhibitor, almost comparable to the parent compound.
