New analogs of the PPAR pan agonist AL29-26 encompassed ligand (S)-7 showing potent activation of PPARα and -γ subtypes as a partial agonist. In vitro experiments and docking studies in the presence of PPAR antagonists were performed to help interpretation of biological data and investigate the main interactions at the binding sites. Further in vitro experiments showed that (S)-7 induced anti-steatotic effects and enhancement of the glucose uptake. This latter effect could be partially ascribed to a significant inhibition of the mitochondrial pyruvate carrier demonstrating that (S)-7 also acted through insulin-independent mechanisms. In vivo experiments showed that this compound reduced blood glucose and lipid levels in a diabetic mice model displaying no toxicity on bone, kidney, and liver. To our knowledge, this is the first example of dual PPARα/γ partial agonist showing these combined effects representing, therefore, the potential lead of new drugs for treatment of dyslipidemic type 2 diabetes.
新型的 PPAR 全激动剂 AL29-26 的类似物包含配体 (S)-7,其作为部分激动剂能够强烈激活 PPARα 和 -γ 亚型。进行了体外实验和在 PPAR 拮抗剂存在下的对接研究,以帮助解释生物学数据并研究结合部位的主要相互作用。进一步的体外实验表明,(S)-7 诱导抗脂肪变性作用和葡萄糖摄取增强。后一种作用可以部分归因于对线粒体丙酮酸载体的显著抑制,表明 (S)-7 还通过胰岛素非依赖性机制起作用。体内实验表明,该化合物可降低糖尿病小鼠模型的血糖和血脂水平,对骨骼、肾脏和肝脏无毒性。据我们所知,这是首例具有这些联合作用的双重 PPARα/γ 部分激动剂,代表了治疗血脂异常 2 型糖尿病的新型药物的潜在先导化合物。
