Bioactivity | Angiopeptin, a cyclic octapeptide analogue of somatostatin, is a weak sst2/sst5 receptor partial agonist with IC50 values of 0.26 nM and 6.92 nM, respectively. Angiopeptin is a potent inhibitor of growth hormone release and insulin-like growth factor-1 (IGF-1) production. Angiopeptin inhibits adenylate cyclase or stimulates extracellular acidification. Angiopeptin has the potential for coronary atherosclerosis research[1][2]. |
Target | IC50: 0.26 nM (sst2) and 6.92 nM (sst5) |
Invitro | Angiopeptin (0.1 nM- 10 μM; for 1 h) acts as a partial agonist (pEC50=6.57) with a maximum response of 423% at 3 μM on the release of tritium on CHO hsst2 cells[2]. |
In Vivo | Angiopeptin (20 and 50μg/kg; i.h.) significantly inhibits neointimal formation[1].Angiopeptin (20 μg/kg; per day) significantly inhibits coronary artery myointimal proliferation in cardiac allografts by appmximalely 50%[1]. |
