A library, evaluating a range of piperazines, piperidines and acyclic amines, as replacements for the 4-hydroxy-4-phenylpiperidine moiety in lead (1b) was prepared. These efforts identified the 4-((N)-benzimidazolone)piperidine analogue (2a) which was further optimised using classical single-compound synthesis to yield the 3-((N)-morpholino)azetidine (2j). Conformationally constrained analogues of (2j), generally offered no potency advantage in this particular series.

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.

The present invention concerns the novel use of aryl substituted heterocycles of formula I, set out below, which antagonize the pharmacological actions of one of ent endogenous neuropeptide tachykinins an 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. Certain novel aryl substituted heterocycles of formula I and novel intermediates for their manufacture are also provided. STR1
