A pyrazolo[1,5-a]pyridine derivative represented by formula (I) and salt thereof exhibit excellent MAPKAP-K2 inhibitory activity. Accordingly, medicines comprising this compound as an active ingredient are expected to be valuable for treating or preventing diseases mediated by MAPKAP-K2 such as inflammatory injury, autoimmune diseases, asteropathia destruens, cancer and/or growth of tumor.
one-step synthetic protocol toward multifunctionalized m-terphenyls 5 and sulfonyl m-terphenyls 6 is developed from substituted chalcones 1 and allyl sulfone 2 in good yields via a [3C+3C] annulation. The NaH-mediated annulation features transition metal catalyst-free condition. Chalcones 1 with the functional groups tolerance are easily prepared via Claisen–Schmidt condensation of substituted benzaldehydes
