HETEROCYCLIC DERIVATIVES AS M-GLU5 ANTAGONISTS

摘要

Novel compounds I (R1 = a mono or bicyclic C1-C9 heterocyclic group containing from 1 to 3 heteroatoms chosen from N, O and S, a phenyl group, a C3-C6 cycloalkyl group, or a C3-C6 cycloalkenyl group, each of which may optionally be substituted; R2 = a mono or bicyclic C1-C9 heterocyclic group containing from 1 to 3 heteroatoms chosen from N, O and S, or a phenyl group, each of which may optionally be substituted; R3 = H, F, CN or an optionally substituted C1-C6 alkyl group, m is 0, 1 or 2; and n is 0, 1 or 2) are antagonists selective for the metabotropic mGlu5 receptor, useful for the treatment of neuromuscular dysfunction of the lower urinary tract in a mammal. Further uses include the treatment of migraine; gastroesophageal reflux disease (GERD); anxiety disorder; abuse, substance dependence and substance withdrawal disorder; neuropathic pain disorder; and fragile X syndrome disorders.
