PPARα:100 nM (EC50, Human PPARα)

AVE8134 is a full PPARα dominated PPAR agonist, but not active on PPARδ[1]. In HUVEC, AVE8134 (1 μM) increases Ser-1177-eNOS phosphorylation but not eNOS expression. In monocytes, AVE8134 (10 μM) increases the expression of CD36 and the macrophage scavenger receptor 1, resulting in enhanced uptake of oxidized LDL[2].

In female hApo A1 mice, AVE8134 (130 mg/kg/d, po for 12 d) dose-dependently loweres the plasma triglycerides, and increases the serum HDL-cholesterol, hApo A1 and mouse Apo E levels. In female ZDF rats, AVE8134 (3-30 mg/kg/d for 2 weeks) improves insulin-sensitivity index. In pre-diabetic male ZDF rats, AVE8134 (10 mg/kg/d for 8 weeks) produces an anti-diabetic action comparable to rosiglitazone, without the PPARγ mediated adverse effects on body weight and heart weight. In male ZDF rats, AVE8134 (20 mg/kg/d for 12 weeks) increases mRNA levels of the target genes LPL and PDK4 about 20 fold in the liver, and there is no relevant effect with rosiglitazone[1]. In post-MI rats, AVE8134 (3 mg/kg and 10 mg/kg) dose-dependently improves cardiac output, myocardial contractility and relaxation and reduces lung and left ventricular weight and fibrosis. Treatment at AVE8134 decreases plasma proBNP and arginine and increases plasma citrulline and urinary NOx/creatinine ratio. In DOCA rats, AVE8134 (3 mg/kg/d) prevents development of high blood pressure, myocardial hypertrophy and cardiac fibrosis, and ameliorates endothelial dysfunction. In old SHR, treatment with a low dose of AVE8134 (0.3 mg/kg/d) improves cardiac and vascular function and increases life expectancy without lowering blood pressure. AVE8134 reduces phenylephrine-induced hypertrophy in adult rat cardiomyocytes[2].

Male ZDF rats are treated for 8 weeks. Food consumption and body weight are measured twice a week. The amount of diet for an additional control group is restricted to levels below the estimated consumption of the AVE8134 group: the starting value is 7 g chow/100 g body weight for the first week and than adapted to 8 g/100 g body weight. The chow for that control group is divided into two portions and is offered twice daily when light is switched on and off, all other groups had free access to food, except before measurements of fasted blood glucose, insulin and before oral glucose tolerance test. After two weeks of treatment an oral glucose tolerance test (oGTT) is performed. Briefly, after an overnight fast, the animals are treated with the drugs or vehicle between 06:30 and 07:00, glucose (2 g/kg) is administered orally 2 h later in a volume of 5 mL/kg, blood is drawn from the tip of the tail from using glass capillaries at 0, 30, 60, 90, 120, and 180 min after glucose administration. The glycemic index (GI) is calculated as area under the curve (AUC) of glucose response during oGTT. Blood glucose concentration before oral glucose load (0 min) is defined as baseline of AUC calculation.
