Identification of highly potent and orally available free fatty acid receptor 1 agonists bearing isoxazole scaffold

The free fatty acid receptor 1 (FFA1) is being considered to be a novel anti-diabetic target based on its role in amplifying insulin secretion. We have previously identified several series of FFA1 agonists with different heterocyclic scaffolds. Herein, we describe the structural exploration of other heterocyclic scaffolds directed by drug-like physicochemical properties. Further structure-based design and chiral resolution provided the most potent compound 11 (EC50 = 7.9 nM), which exhibited improved lipophilicity (LogD7.4: 1.93), ligand efficiency (LE = 0.32) and ligand lipophilicity efficiency (LLE = 6.2). Moreover, compound 11 revealed an even better pharmacokinetic property than that of TAK-875 in terms of plasma clearance, maximum concentration, and plasma exposure. Although robust agonistic activity and PK profiles for compound 11, the glucose-lowering effects in vivo is not ideal, and the exact reason for in vitro/in vivo difference was worthy for further exploration.

Palladium-catalyzed direct arylation of pyrazole derivatives: A green access to 4-arylpyrazoles

1,3,5-Trisubstituted pyrazoles were found to be suitable partners for palladium-catalyzed direct arylation via C-H activation/functionalization using aryl bromides. The reaction conditions and the catalyst have a determining influence on the yields. The system using palladium(II) acetate as the catalyst, potassium acetate as the base, and N,N-dimethylacetamide as the solvent promotes selective 4-arylations in moderate to high yields. Several aryl and heteroaryl bromide derivatives have been employed successfully; their electronic properties have a decisive influence on the yields of coupling products. Electron-poor aryl bromides gave satisfactory results, whereas the electron-rich ones gave lower yields. Georg Thieme Verlag Stuttgart - New York.
