摘要：

Experiments using muscarinic receptor antagonists were done to determine which muscarinic receptor subtype(s) mediate carbachol-evoked calcium release in N1E-115 cells. McN-A-343 and a new analog, (+/-)BN228, were weak antagonists and neither compound caused release on its own. The rank order of potency was 4-DAMP > pirenzepine > AFDX116 > (+/-)BN228 and McN-A-343. This profile, pirenzepine's high potency (19-fold greater than AFDX116) and its IC50 of 31 nM suggest that calcium release in this neuronal cell line is mediated by the M1 muscarinic receptor subtype.
