  J-104129, a novel muscarinic M3 receptor antagonist with high selectivity for M3 over M2 receptors

  摘要：

  A new class of 4-acetamidopiperidine derivatives has been synthesized and investigated for human muscarinic receptor subtype selectivity. Introduction of a hydrocarbon chain of appropriate length into the piperidine nitrogen of the racemic N-(piperidin-4-yl)-2-cyclobutyl-2-hydroxy-2-phenylacetamide platform conferred up to 70-fold selectivity for human muscarinic M-3 receptors over M-2 receptors. Subsequent synthetic derivatizations resulted in highly potent M-3 receptor antagonists with selectivity greater than two orders of magnitude for M-3 over M-2 receptors, from which the analogue 4r was selected. Preparation of both enantiomers of 4r led to the identification of (2R)-N-[1-(4-methyl-3-pentenyl)piperidin-4-yl]-2-cyclopentyl-2-hydroxy-2-phenylacetamide (J-104129, (R)-4r), which exhibited 120-fold selectivity for Mg receptors (K-i = 4.2 nM) over M-2 receptors (K-i = 490 nM). In isolated rat trachea, (R)-4r potently and specifically antagonized acetylcholine (ACh)-induced responses with a K-B value of 3.3 nM. The highly subtype-selective profile was also seen in isolated rat tissue assays (50-fold) and in anesthetized rats (> 250-fold). Oral administration of J-104129 ((R)-4r) antagonized ACh-induced bronchoconstriction with an ED50 value of 0.58 mg/kg in rats. Thus, J-104129 ((R)-4r) may effectively facilitate bronchodilation in the treatment of obstructive airway disease. (C) 1999 Elsevier Science Ltd. All rights reserved.

  Novel fluorine-containing 1,4-disubstituted piperidine derivatives, represented by general formula \x9bI! ##STR1## such as, for example, (2R)-N-\x9b1-(6-aminopyridin-2-ylmethyl)piperidin-4-yl!-2-\x9b(1R)-3,3-difluoroc yclopentyl!-2-hydroxy-2-phenylacetamide or pharmaceutically acceptable salt thereof, are potent and selective antagonists for muscarinic M.sub.3 receptors with little side effects. The compounds of formula \x9bI! exhibit excellent oral activity, duration of activity and pharmacolkinetics. They are useful for treatment and prophylaxis of respiratory diseases, such as chronic obstructive pulmonary diseases; urinary diseases, such as urinary incontinence; and digestive diseases, such as irritable bowel syndrome, and motion sickness.
