α-Glucopyranoimidazolines as intermediate analogue inhibitors of family 20 β-N-acetylglucosaminidases
摘要:
The alpha-glucopyranoimidazolines, 2-methyl-(1,2-dideoxy-alpha-D-glucopyrano)[2,1-d]-1-imidazolines 1 and 2, have been synthesized and evaluated as inhibitors of beta-N-acetylglucosaminidases (NAGs). Compounds I and 2, mimicking the oxazolinium ion intermediate in enzyme catalysis, served as potent and competitive inhibitors of family 20 NAGs with K-i as low as 0.1 muM, but showed no inhibitory activities toward family 3 NAGs. Due to structural and electrostatic resemblance to the oxazolinium ion intermediate, the alpha-glucopyranoimidazolines may lead to novel and selective inhibitors of mechanistically related glycosidases such as family 18 chitinases.
