产品描述:
TAK-385 is an orally bioavailable gonadotropin-releasing hormone receptor (GnRHR) antagonist (IC50s = 0.33 and 0.32 nM for the human and monkey receptors, respectively).{49487} It is selective for these receptors over the rat GnRHR receptor (IC50 = 9,800 nM), as well as a panel of 134 enzymes and receptors at 10 µM. TAK-385 is 95-fold more potent at inhibiting GnRH-induced arachidonic acid (Item Nos. 90010 | 90010.1 | 10006607) release in CHO cells expressing human GnRHR compared with those expressing monkey GnRHR. It decreases testis, ventral prostate, ovary, and uterus weight in human GNRHR knock-in mice when administered at doses ranging from 3 to 200 mg/kg per day for 28 days.{49488} TAK-385 (1 and 3 mg/kg) also decreases plasma luteinizing hormone levels in castrated cynomolgus monkeys.{49487}
