Emiglitate  (Synonyms: BAY o 1248)

Emiglitate (BAY o 1248) is a potent, selective and competitive inhibitor of α-glucoside hydrolase.

Emiglitate greatly suppresses the glucose-stimulated insulin release in parallel with an inhibitory effect on the activities of acid glucan-1,4-α-glucosidase and acid α-glucosidase. In contrast, the activities of acid phosphatase and N-acetyl-β-D-glucosaminidase tend to increase in the presence of the α-glucoside hydrolase inhibitor. The CO-induced amplification of the glucose-stimulated insulin release as well as of the increased activities of the acid α-glucoside hydrolases are abrogated by emiglitate and displayed the same levels as in the absence of CO. The CO-induced rise in the activities of acid phosphatase and acid N-acetyl-β-D-glucosaminidase is not appreciably affected by emiglitate^[1].

In fasted rats, emiglitate inducec a significant, dose-dependent increase of hepatic glycogen concentrations. The increase in hepatic glycogen is due to lysosomal storage of glycogen only. Emiglitate in the amount of 5 mg/kg b.wt. does not induce significant changes either of glycogen concentrations or at the EM-level^[2].
