Oligosaccharides alpha amylase inhibitors

Carba-oligosaccharidic Alpha Amylase Inhibitors and Related Compounds. . 81... 

Carba-glycosylamines [2,3,4-trihydroxy-5-(hydroxymethyl)-1 -cyclohex-ylamine] and related compounds are well known to exist as components of the antibiotic validamycin complex and carba-oligosaccharidic alpha amylase inhibitors. ... 

Several mono-carba-oligosaccharidic alpha amylase inhibitors, such as acarbose and its homologs, amylostatins, trestatins, oligostatins, adipo-sins, and so on, have been isolated from cultures of micro-organisms, and considerable interest in the biochemistry and chemistry of this class of inhibitors has been stimulated. The characteristic core-structure for inhibitory action is composed of a trihydroxy(hydroxymethyl)cyclohexene moiety and a 4-amino-4,6-dideoxy-D-glucopyranose moiety, bonded by way of an imino linkage at the allylic position. A similar structural unit has been found in the antibiotic validamycins.
