Pharmacological properties of oxotremorine and its analogs.
The mechanism of action of oxotremorine is reviewed. A number of analogs of oxotremorine, including agonists, partial agonists and antagonists, are described. Many of these are potent and highlyExpand

Regional differences in receptor reserve for analogs of oxotremorine in vivo: implications for development of selective muscarinic agonists.
The muscarinic actions of several analogs of oxotremorine were compared in the mouse. Compounds such as AKS 19 and BM 5 having low intrinsic efficacy (partial agonists) differentiated betweenExpand

The conversion of 2-chloroalkylamine analogues of oxotremorine to aziridinium ions and their interactions with muscarinic receptors in the guinea pig ileum.
Two mustard analogues of oxotremorine, N-[4-(2-chloroethylmethylamino)-2-butynyl]-2-pyrrolidone (BM 123) and N-[4-(2-chloromethylpyrrolidino)-2-butynyl]-2-pyrrolidone (BM 130), were synthesized. BMExpand
