ABSTRACT:
An acid addition salt of a carba-sugar amine derivative represented by the following formula (1):wherein R1and R2each independently represents a hydrogen atom, or an alkyl group, an alkenyl group, an alkynyl group, an acyl group, an aryl group or an aralkyl group which may have one or at least two of the following substituent (I) or (II), or R1and R2are taken together to represent a substituent (III)(R8to R12each independently represents an alkyl group, an alkenyl group, an alkynyl group, an acyl group, an aryl group or an aralkyl group), with the proviso that both R1and R2are not a hydrogen atom at the same time; R3, R4and R7each independently represents a hydroxyl group or a hydroxyl group having a substituent; and R5and R6each independently represents a hydrogen atom, or a hydroxyl group or a hydroxyl group having a substituent, with the proviso that when one of R5and R6is a hydrogen atom, the other is a hydroxyl group or a hydroxyl group having a substituent.
