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.
