The present invention concerns the novel aryl substituted heterocycles of formula I, set out below,
wherein R², R³ and R⁴ 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 aryl substituted heterocycles for use in such treatment, methods for their use, and processes and novel intermediates for their manufacture.
本发明涉及如下式 I 的新型芳基取代杂环,其中 R²、R³ 和 R⁴ 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,因此在需要这种拮抗作用时,例如在治疗哮喘和相关病症时,它们是有用的。 本发明还提供了用于此类治疗的含有芳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。
