4-Alkylpiperidines related to SR-48968: Potent antagonists of the neurokinin-2 (NK2) receptor
摘要:
A series of 4-alkylpiperidine derivatives related to the potent neurokinin-2 (NK2) receptor antagonist SR-48968 (1) is described. Simple aliphatic derivatives were found to be poorly active, but appropriate placement of an alcohol functional group afforded compounds that were of similar activity to 1. Several representatives in this series, such as the 4-(1-hydroxy-1-ethylpropyl)piperidine (14), were found to exhibit oral activity in a model of labored abdominal breathing in guinea pigs. These results expand the latitude of substituents available in this region of this series of NK2 receptor antagonists. (C) 1998 Elsevier Science Ltd. All rights reserved.

The present invention concerns the novel alkyl substituted heterocycles of formula I, set out below, wherein Q, Q¹, Q² and R have the values defined herein, which antagonize the pharmacological actions of one of the endogenous neuropeptide tachykinins at the neurokinin 2 (NK2) receptor making them useful whenever such antagonism is desired, such as in the treatment of asthma and related conditions. The invention also provides pharmaceutical compositions containing the alkyl substituted heterocycles for use in such treatment, methods for their use, and processes and novel intermediates for their manufacture.
本发明涉及下式 I 的新型烷基取代杂环,其中 Q、Q¹、Q² 和 R 具有本文所定义的值,该杂环可拮抗内源性神经肽之一速激肽在神经激肽 2 (NK2) 受体上的药理作用,使其在需要这种拮抗作用时非常有用,例如在治疗哮喘和相关疾病时。本发明还提供了用于此类治疗的含有烷基取代杂环的药物组合物、使用方法以及生产工艺和新型中间体。
