Biochem/physiol Actions 3-Benzidino-6-(4-chlorophenyl)pyridazine is an inhibitor of delayed rectifier and transient outward potassium currents. The IC50 values for the blocking action of BCP on IKDR and IKA was calculated as 7.13 μM and 0.55 μM, respectively in acutely isolated rat hippocampal pyramidal neurons by using whole-cell patch-clamp technique. The parent compound, minaprine (Cat. No. M3157), has selective affinity for M1 muscarinic receptors and possesses memory-enhancing properties and also acts as an antidepressant. |
