Target

Encephalin convertase, Ki 值为8.8 nM.

In Vitro GEMSA inhibits the activation of TAFI and porcine CBB[1]. GEMSA can inhibit the prolongation of lysis time in recombinant BAP and does not lead to the lysis of APC fibronectin[1]. GEMSA inhibits the prolongation of lysis time in porcine CPB, TAFI, and recombinant BAP, APC with the EC50 values of 0.34 μM, 100μM, 115 μM, 90 μM respectively[1][2].
In Vivo GEMSA (ICV, 0.1μg/mg, every, 3days) results in a 75% increase in hypothalamic luteinizing hormone-releasing hormone and serum luteinizing hormone levels, and a 60% decrease in serum prolactin concentrations in rat[3]
