BAY-298 是一种口服有效和选择性的促黄体生成激素受体 (LH-R) 拮抗剂,对 hLH (人 LH),rLH (大鼠 LH)和 cLH (食蟹猴LH) 的IC50分别为 96 nM,23 nM 和 78 nM。BAY-298 可以降低性激素水平。
生物活性 | BAY-298 is an orally active and selectiveluteinizing hormone receptor (LH-R)antagonist withIC50s of 96 nM, 23 nM and 78 nM for hLH (human LH) and rLH (rat LH) and cLH (cynomolgus monkey LH), respectively. BAY-298 can reduce sex hormone levels[1]. |
IC50& Target | IC50: 185 nM (hLH), 46nM (rLH) and 78 nM (cLH)[1] |
体内研究 (In Vivo) | BAY-298 (oral; 4.5-72 mg/kg/day; for 8 days) dosedependently loweres serum estradiol levels in proestrus[1]. BAY-298 (iv of 0.5 mg/kg or po of 2 mg/kg) has t1/2s of 31 hours and 33 hours for iv and po. And the Cmaxs are 0.28 kg/L and 0.066 kg/L for iv and po[1].
Animal Model: | Intact female rats[1] | Dosage: | 4.5, 9, 18, 36, 72 mg/kg | Administration: | Oral; for 8 days | Result: | Dosedependently lowered serum estradiol levels in proestrus. |
Animal Model: | Female and male Wistar rats[1] | Dosage: | 0.5 mg/kg of iv or 2 mg/kg of po | Administration: | Iv or po | Result: | Has t1/2s of 31 hours and 33 hours for iv and po. And the Cmaxs are 0.28 kg/L and 0.066 kg/L for iv and po. |
