Palosuran (ACT-058362) 是一种有效,选择性和具有口服活性的urotensin II receptor受体拮抗剂,对于表达人重组受体的 CHO 细胞膜的IC50值为 3.6 nM。Palosuran 可改善糖尿病大鼠的胰腺和肾脏功能。
生物活性 | Palosuran (ACT-058362) is a potent, selective, and orally active antagonist ofurotensin II receptor, with anIC50of 3.6 nM for CHO cell membranes expressing human recombinant receptors. Palosuran can improves pancreatic and renal function in diabetic rats[1][2]. |
IC50& Target | IC50: 3.6 nM (human urotensin II receptor)[1] |
体外研究 (In Vitro) | Palosuran (8 h) inhibits125I-U-II binding to human UT receptor, with IC50s of 46.2 nM on TE 671 cells and 86 nM on recombinant CHO cells[1]. Palosuran inhibits Ca2+mobilization in response to human U-II in CHO cells expressing human and rat UT receptor with IC50s of 17 and >10000 nM, respectively[1]. Palosuran (0.12-10000 nM; 20 min) inhibits human U-II induced MAPK phosphorylation in a dose-dependent manner in recombinant CHO cells, with an IC50of 150 nM[1].

体内研究 (In Vivo) | ACT-058362 (10 mg/kg/h; i.v.) fully prevents the decrease in renal blood flow after ischemia in rats without decreasing blood pressure[1]. Palosuran (300 mg/kg/d; p.o. for 16 weeks) improves the survival, increases insulin, and slows the increase in glycemia, glycosylated hemoglobin, and serum lipids in streptozotocin-induced diabetic rats[2].
Animal Model: | Male Wistar rats with renal ischemia and reperfusion[1] | Dosage: | 20 mg/kg/h for 135 min | Administration: | I.v. (continuous infusion) for 135 min | Result: | Restored renal blood flow to baseline values at 30 min after reperfusion and by 60 min increased renal blood flow by 12% above baseline values. Did not significantly alter mean arterial blood pressure (MAP) and heart rate (HR). |
