  Muscarinic receptor binding and activation of second messengers by substituted N-methyl-N-[4-(1-azacycloalkyl)-2-butynyl]acetamides

  摘要：

  A series of substituted azacycloalkyl analogues of the muscarinic agonist UH 5 (N-methyl-N-[4-(1-pyrrolidinyl)-2-butynyl]acetamide, 1a) were synthesized and evaluated pharmacologically. These compounds were developed as intermediates for further derivatization leading to functionalized congeners of 1a. The compounds were synthesized by using a Mannich-type condensation of N-acetyl-N-methylpropargylamine to various substituted saturated azaheterocycles. The compounds were screened at a single concentration in competitive binding assays in rat cerebral cortical membranes against either [H-3]N-methylscopolamine (at 100-mu-M) or [H-3]oxotremorine-M (at 1-mu-M) labels. Candidates were then selected for further evaluation of their effect on phosphoinositide (PI) turnover in membranes from A9L cells transfected with cDNA of either m1-muscarinic cholinergic receptors (m1AChRs) or m3AChRs. The analogues were also tested for the inhibition of adenylate cyclase in NG108-15 cells expressing m4AChRs. The azetidine analogue of 1a had a K(i) value of 12 nM for the inhibition of [H-3]oxotremorine-M binding in rat brain and had an agonist potency at m1-, m3-, and m4AChRs comparable to 1a. The substituted 5- and 6-member ring analogues generally had lower binding affinities and were less potent than 1a in stimulating PI turnover. Several compounds were moderately effective in inhibiting cyclic AMP production in NG108-15 cells.
