structural modification method to improve compounds’ druggability. However, PEC glycosides were rarely reported in nature which largely limited their further medicinal investigations and applications. In this study, the enzymatic glycosylation of four naturally separated PECs 1−4 was achieved using a promiscuous glycosyltransferase UGT71BD1 identified from Cistanche tubulosa. It could accept UDP-Glucose, U

high potency when the sulfamate group and the side chain are situated in diagonally opposite positions (i.e., 2,6- and 3,7-substitution pattern). The highest activity is achieved with fully branched, bulky aliphatic side chains and with thiochromen-4-one as the core element. 2-(1-Adamantyl)-4H-thiochromen-4-on-6-O-sulfamate (6c) is the most potent STS inhibitor discovered so far, and it is about 170-fold
