  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.

• Dienyne Ring-Closing Metathesis Approach for the Construction of Taxosteroids

  hybrid compounds-the taxosteroids-possessing carbon frameworks incorporating moieties characteristic of both taxanes (such as AB rings) and steroids (i.e., CD system and side chain). This tandem cyclization is highly stereoselective, allowing the one-step formation of the bicyclo[5.3.1]undecene system characteristic of taxol. In this work we describe the scope and limitations of such cyclizations.

  The present invention relates to a process of obtaining taxosteroids and precursors thereof from the hydrindane bicyclic ring system. The compounds have a tetracyclic system which combines the structural characteristics of taxanes, such as the bicyclo[5.3.1]undecane system (cycles A and B), fused to a six-membered ring (C), and of steroids, such as the CD bicycle, the A ring and the side chain (Sc). The process of preparing the compounds and their application as compositions with pharmacological properties of interest are described.
