Atrasentan (ABT-627) 是一种有效的内皮素受体 (endothelin receptor) 拮抗剂,抑制 ETA 的活性,IC50 值为 0.0551 nM.
Atrasentan (ABT-627, (+)-A 127722, A-147627) 是内皮素 A (ETA) 受体拮抗剂,Ki 为 0.034 nM。它通过抑制前列腺癌细胞生长和诱导细胞凋亡来发挥抗肿瘤活性。
Atrasentan (ABT-627, 0-50 μM) significantly inhibits LNCaP and C4-2b prostate cancer cell growth. ABT-627 in conbination with Taxotere elicits a significantly greater loss of viable prostate cancer cells relative to either agent alone and shows greater degree of down-regulation of the NF-κB DNA binding activity. Atrasentan profoundly induces several CYPs and drug transporters (e.g. 12-fold induction of CYP3A4 at 50 μM). It is a moderate P-gp inhibitor (IC50 in P388/dx cells=15.1±1.6 μM) and a weak BCRP inhibitor (IC50 in MDCKII-BCRP cells=59.8±11 μM)
阿曲生坦(3mg/kg,口服)抑制大内皮素-1(1nmol/kg)在髓内大鼠中诱导的升压反应[1]。在SCID-hu模型中,阿曲生坦(ABT-627,10mg/kg,i.p.)以及单独的泰索帝在一定程度上抑制了骨环境中C4-2b肿瘤的生长。
| 动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
