Background on (Z)-Pugnac

(Z)-Pugnac is a potent inhibitor of O-GlcNAcase [1].

Pugnac is an inhibitor of O-GlcNAcase and is initially found to be an inhibitor of β-N-acetylglucosaminidases. It plays its inhibition role through mimicking the substrates of its target enzymes.(Z)-Pugnac is the Z stereoisomer of Pugnac. It is found to be more potent than the E stereoisomer. When tested with the recombinant O-GlcNAcase and the fluorogenic substrate, (Z)-Pugnac inhibited approximately 80% of O-GlcNAcase native activity at concentration of 1 μM. (E)-Pugnac at the same concentration showed only 10% inhibition of the activity. Besides that, (Z)-Pugnac induced about 1.4-fold increased level of O-GlcNAc incorporation on proteins both in HEK cells and in HeLa cells [1].
