To characterize the muscarinic receptor present in guinea-pig uterus smooth muscle the affinities of a series of 27 muscarinic receptor antagonists for M1 (rat cortex), M2 (rat heart), M3 (rat submandibular gland), m4 (transfected in CHO cells) and muscarinic binding sites in guinea-pig uterus smooth muscle were determined in radioligand binding studies. In addition, functional experiments were performed to assess pKB values of the antagonist for muscarinic receptors in guinea-pig atrium and uterus. The results obtained are consistent with the presence of M2 receptors in the uterus through which the functional contractile response is mediated. Correlation coefficients of 0.98, 0.91 and 0.91 were calculated for the following linear regressions: pKi uterus vs. pKi M2, pKB uterus vs. pKi M2 and pKB uterus vs. pKB atrium. This study also revealed that the compounds dicyclomine, DAU 5884, DAU 6202 as well as AQ-RA 721 could distinguish m4 from M2 sites and are therefore important tools to characterize muscarinic receptor subtypes. In addition, DAU 5884 and DAU 6202 have been identified as highly potent M1 selective antagonists.
