Discovery of Biaryl Anthranilides as Full Agonists for the High Affinity Niacin Receptor
摘要:
Biaryl anthranilides are reported as potent and selective full agonists for the high affinity niacin receptor GPR109A. The SAR presented outlines approaches to reduce serum shift and both CYPCYP2C8 and CYP2C9 liabilities, while improving PK and maintaining excellent receptor activity. Compound 2i exhibited good in vivo antilipolytic efficacy while providing a significantly improved therapeutic index over vasodilation (flushing) with respect to niacin in the mouse model.

(HKT). Previously, we have reported the effectiveness of 1,2,4-oxadiazole derivatives acting as larvicides for A. aegypti and AeHKT inhibitors from in vitro and in silico studies. Here, we report the synthesis of new sodium 4-[3-(aryl)-1,2,4-oxadiazol-5-yl] propanoates and the cognate HKT-inhibitory activity. These new derivatives act as competitive inhibitors with IC50 values in the range of 42 to 339

The synthesis of 3-(3-aryl-1,2,4-oxadiazol-5-yl)propionicacids from arylamidoximes and succinic anhydride under focused microwave irradiation conditions is described. The new synthetic method furnished the desired products in 2-3 min and good yields. Furthermore, the previously complicated purification procedure has been simplified in a manner which is quick, eco-friendly and cost-effective. Larvicidal

In this study, a novel series of substituted 4,6-difluoro-2-2-[3-(substituted-phenyl)-[1,2,4]-oxadiazol-5-yl]-ethyl}-1H-benzo[d]imidazole derivatives were synthesized by condensation of 2,4-difluoro 6-nitrophenyl amine with 3-(substitutedphenyl-[1,2,4]-oxadiazol-5yl) propionic acid by using 2,4,6-trichlorobenzoyl chloride in the presence of triethyl amine base. The compounds were evaluated for their
Novel cyclic peptide derivatives based on ogipeptins A, B, C, and D were synthesized. Starting with a mixture of ogipeptins A–D, a practical four-step synthetic procedure was followed to prepare novel derivatives with various kinds of acyl side chains. Among the 45 new synthetic derivatives identified, the antibacterial activities of compounds 8-3 and 8-38 were comparable with those of ogipeptin A
