- Design, synthesis, and structure-activity relationship studies of novel 2,4,6-trisubstituted-5-pyrimidinecarboxylic acids as peroxisome proliferator-activated receptor γ (PPARγ) partial agonists with comparable antidiabetic efficacy to rosiglitazone
-
A series of novel 2,4,6-trisubstitutedpyrimidine-5-carboxylic acid derivatives were designed and synthesized with the intent of producing a peroxisome proliferator-activated receptor γ (PPARγ) partial agonist for antidiabetic agents. A pharmacophore-driven approach of in-house screening identified compound 7, which led to the identification of compound 9 featuring a 2,4,6-trisubstituted pyrimidine-5-carboxylic acid core. Structure-activity relationship studies of 9 resulted in identifying 4,6-bisbenzylthio-2- methylthiopyrimidine-5-carboxylic acid (50) as the most attractive of all the screened compounds. The X-ray cocrystal structure of 50 bound on PPARγ revealed that the key hydrogen bond interactions, which are not related to the activation function 2 (AF-2) site, are different from those of the full agonist. Compound 50 showed typical PPARγ partial agonist properties in the PPARγ-GAL4 functional assay and weaker differentiation of adipocytes in 3T3-L1 cells than observed with rosiglitazone. Furthermore, 50 displayed comparable antidiabetic efficacy with rosiglitazone in db/db mice, although its potency is 10-fold weaker than that of rosiglitazone.
