Discovery of phenylsulfonyl acetic acid derivatives with improved efficacy and safety as potent free fatty acid receptor 1 agonists for the treatment of type 2 diabetes
structure-activity relationship study based on the previleged scaffolds led to the discovery of 2-(4-[(2'-chloro-[1,1'-biphenyl]-3-yl)methoxy]phenyl)sulfonyl}acetic acid (compound 20), which showed a better balance than compound 2 in terms of physicochemicalproperties, cytotoxicity profiles and pharmacokinetic properties. Subsequent in vivo studies demonstrated that compound 20 robustly improves the
The free fatty acid receptor 1 (FFA1 or GPR40) and peroxisome proliferator-activated receptor delta (PPAR delta) have attracted a lot of attention due to their role in promoting insulin secretion and sensibility, respectively, which are two major features of diabetes. Therefore, the dual FFA1/PPAR delta agonists would increase insulin secretion and sensibility by FFA1 and PPAR delta activation. In this study, we hybrid FFA1 agonist AM-4668 with PPAR delta agonist GW501516, leading to the identification of orally bioavailable dual agonist 32, which revealed high selectivity over other PPAR delta. Moreover, compound 32 exhibited good pharmacokinetic profiles with high plasma concentration, sustained half-life and low clearance in vivo. During the hypoglycemic test, a dual agonist 32 enhanced the tolerance of ob/ob mice for glucose loading in a dose-dependent manner. Our results suggest that dual FFA1/PPAR delta agonist could be a valuable therapy for type 2 diabetes. (C) 2018 Elsevier Masson SAS. All rights reserved.
Design, synthesis and Structure–activity relationship studies of new thiazole-based free fatty acid receptor 1 agonists for the treatment of type 2 diabetes
The free fatty acid receptor 1 (FFA1/GPR40) has attracted interest as a novel target for the treatment of type 2 diabetes. Several series of FFA1 agonists including TAK-875, the most advanced compound terminated in phase III studies due to concerns about liver toxicity, have been hampered by relatively high molecular weight and lipophilicity. Aiming to develop potent FFA1 agonists with low risk of
