Bioactivity | Azemiopsin is a potent nicotinic acetylcholine receptor (nAChR) inhibitor with IC50s of 0.18 μM and 22 μM against T. californica nAChR and human α7 nAChR, respectively. Azemiopsin blocks acetylcholine-induced currents in Xenopus oocytes heterologously expressing human muscle-type nAChR[1]. |
Target | IC50: 0.18 μM (T. californica nAChR), 22 μM (Human α7 nAChR), 63 μM (L. stagnalis AChBP), 230 μM (A. californica AChBP) |
