  • Carba-sugar amine derivative and glycolipid metabolic disorder treating agent containing the same as active ingredient
    Patent number: 7790773
    Abstract: A carba-sugar amine derivative represented by the following formula (1) or (2) is used as the active ingredient of a ?-galactosidase inhibitor or a glycolipid metabolic disorder treating agent. Wherein each of R1 and R2 independently represents H, an alkyl group, an acyl group, an aryl group or an aralkyl group, with the proviso that both are not H at the same time, and each of R3, R4, R5 and R6 independently represents a hydroxyl group or hydroxyl group having a substituent. Also, R7 represents an alkyl group, and each of R8, R9, R10 and R11 independently represents a hydroxyl group or a hydroxyl group having a substituent.
