產品描述: | Palosuran (ACT-058362) is a potent, selective, and orally active antagonist of urotensin II receptor, with an IC50 of 3.6 nM for CHO cell membranes expressing human recombinant receptors. Palosuran can improves pancreatic and renal function in diabetic rats |
靶點: |
IC50: 3.6 nM (human urotensin II receptor);GPR |
體外研究: |
Palosuran (8 h) inhibits 125I-U-II binding to human UT receptor, with IC50s of 46.2 nM on TE 671 cells and 86 nM on recombinant CHO cells. 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. 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 IC50 of 150 nM |
體內研究: |
ACT-058362 (10 mg/kg/h; i.v.) fully prevents the decrease in renal blood flow after ischemia in rats without decreasing blood pressure. 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. Animal Model: Male Wistar rats with renal ischemia and reperfusion 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). |
