  Novel pyrazolo[1,5-a]pyridine derivatives were designed, synthesized and evaluated as orally active EP1 antagonists for the treatment of overactive bladder. Matched molecular pair analysis (MMPA) allowed the design of a new series of pyrazolo[1,5-a]pyridine derivatives 4-6. Structure-activity relationships (SAR) studies of 4-6 were performed, leading to identification of the nanomolar-level EP1 antagonist
