摘要:
Replacement of the methyl-thiazole moiety of GW501516 (a PPAR delta selective agonist) with [1,2,4]thiadiazole gave compound 21 which unexpectedly displayed submicromolar potency as a partial agonist at PPAR alpha in addition to the high potency at PPAR delta. A structure-activity relationships study of 21 resulted in the identification of 40 as a potent and selective PPAR alpha/delta dual agonist. Compound 40 and its close analogs represent a new series of PPAR alpha/delta dual agonists. The high potency, high selectivity, significant gene induction, excellent PK profiles, low P450 inhibition or induction, and good in vivo efficacy in four animal models support 40 being selected as a pre-clinical study candidate, and may render 40 as a valuable pharmacological tool in elucidating the complex roles of PPAR alpha/delta dual agonists, and the potential usage for the treatment of metabolic syndrome.
