- Discovery of first-in-class thiazole-based dual FFA1/PPARδ agonists as potential anti-diabetic agents
-
The free fatty acid receptor 1 (FFA1 or GPR40) and peroxisome proliferator-activated receptor δ (PPARδ) 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/PPARδ agonists would increase insulin secretion and sensibility by FFA1 and PPARδ activation. In this study, we hybrid FFA1 agonist AM-4668 with PPARδ agonist GW501516, leading to the identification of orally bioavailable dual agonist 32, which revealed high selectivity over other PPARs. 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/PPARδ agonist could be a valuable therapy for type 2 diabetes.

- Discovery of HWL-088: A highly potent FFA1/GPR40 agonist bearing a phenoxyacetic acid scaffold
-
Based on a previously reported phenoxyacetic acid scaffold, compound 7 (HWL-088) has been identified as a superior free fatty acid receptor 1 (FFA1) agonist by comprehensive structure-activity relationship study. Our results indicated that the introduction of ortho-fluoro greatly increased the activity of phenoxyacetic acid series, and the unique structure-activity relationship in biphenyl moiety is different from previously reported FFA1 agonists. Moreover, the modeling study was also performed to better understand the binding mode of present series. Compound 7 significantly improved glucose tolerance both in normal and diabetic models, and even exerted greater potential on glucose control than that of TAK-875. These findings provided a novel candidate HWL-088, which is currently in preclinical study to evaluate its potential for the treatment of diabetes.

- Synthesis and biological evaluation of phenoxyacetic acid derivatives as novel free fatty acid receptor 1 agonists
-
Free fatty acid receptor 1 (FFA1) is a new potential drug target for the treatment of type 2 diabetes because of its role in amplifying glucose-stimulated insulin secretion in pancreatic β-cell. In the present studies, we identified phenoxyacetic acid derivative (18b) as a potent FFA1 agonist (EC50 = 62.3 nM) based on the structure of phenylpropanoic acid derivative 4p. Moreover, compound 18b could significantly improve oral glucose tolerance in ICR mice and dose-dependently reduced glucose levels in type 2 diabetic C57BL/6 mice without observation of hypoglycemic side effect. Additionally, compound 18b exhibited acceptable PK profiles. In summary, compound 18b with ideal PK profiles exhibited good activity in vitro and in vivo, and might be a promising drug candidate for the treatment of diabetes mellitus.

- 1,3,5-Trisubstituted aryls as highly selective PPARδ agonists
-
A series of highly potent and selective PPARδ agonists is described using the known non-selective ligand GW2433 as a structural template. Compound 1 is bioavailable, potent (10 nM), and shows no cross-activity with other PPAR subtypes up to 10 μM, making it a useful tool in studying the biological effects of selective PPARδ activation.

- Novel selective small molecule agonists for peroxisome proliferator-activated receptor δ (PPARδ) - Synthesis and biological activity
-
We report the synthesis and biological activity of a new series of small molecule agonists of the human Peroxisome Proliferator-Activated Receptor δ (PPARδ). Several hits were identified from our original libraries containing lipophilic carboxylic acids. Optimization of these hits by structure-guided design led to 7k (GW501516) and 7l (GW0742), which shows an EC50 of 1.1 nM against PPARδ with 1000-fold selectivity over the other human subtypes.
