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.
