  名称：

  A Potent, Long-Acting, Orally Active (2R)-2-[(1R)-3,3-Difluorocyclopentyl]-2-hydroxy-2-phenylacetamide:  A Novel Muscarinic M₃ Receptor Antagonist with High Selectivity for M₃ over M₂ Receptors

  摘要：

  A novel series of (2R)-2-[(1R)-3,3-difluorocyclopentyl]-2-hydroxy-2-phenylacetamides was designed and synthesized based on the structure and biological profiles of an active metabolite 2 of our prototype muscarinic M-3 receptor selective antagonist 1, to develop a potent, long-acting, orally active M-3 antagonist for the treatment of urinary tract disorders, irritable bowel syndrome, and respiratory disorders. Investigation of (2R)-2-[(IR)-3,3-difluorocyclopentyl] -2-hydroxy-2-phenylacetamides containing a phenyl or heterocyclic ring as the piperidinyl side chain in place of the 4-methyl-3-pentenyl moiety of 15a revealed that this acid moiety was a versatile template for improving the selectivity for M-3 over M-2 receptors in comparison With the corresponding cyclopentylphenylacetic acid group: However, since the in vitro metabolic stability of these analogues was insufficient compared with that of 2, further derivatization was performed by introducing an appropriate hydrophilic group into the phenyl or 2-pyridyl ring. Thus, the 1;(6-aminopyridin-2-ylmethyl)piperidine analogue 15y exhibiting 190-fold selectivity for M-3 receptors (K-i = 2.8 nM) over M-2 receptors (K-i = 530 nM) in a human binding assay and-good in vitro metabolic stability in dog and human hepatic microsomes:was identified; This compound has excellent oral activity at 4 h after oral dosing (1 mg/kg), inhibiting methacholine-induced : bronchoconstriction in dogs, and may be useful in clinical situations in which M-3 over M-2 selectivity is desirable.

  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.
