    Product Description

    Kifunensine was originally isolated from the actinomycete Kitasatosporia kifunensine No. 9482 and shown to be a weak inhibitor of aryl mannosidase.1,2 It has since been shown to be a potent and selective inhibitor of class I α-mannosidases and may serve as a key inhibitor of glycoprotein biosynthesis.3 Kifunensine inhibits both human endoplasmic reticulum α-1,2-mannosidase I and members of the Golgi subfamily of the class I mannosidases (Golgi α-mannosidase IA, IB, and IC) exhibiting Ki values of 130 and 23 nM, respectively. It also inhibits mung bean α-1,2-mannosidase I with an IC50 value of 20-50 nM.3 Kifunensine can be used to block α-mannosidase I activity at the endoplasmic reticulum (ER), preventing the removal of desired mutated proteins through ER quality control mechanisms.4,5
