已显示一系列咪唑并[1,2- b ]噻唑衍生物可激活NAD +依赖性脱乙酰基酶SIRT1,这是治疗各种代谢疾病的潜在新治疗靶标。该系列化合物是从带有恶唑烷吡啶核的高通量筛选命中获得的。水溶性基团可方便地安装在咪唑并[1,2- b ]噻唑环的C-2或C-3位置。可以通过修饰这些咪唑并[1,2- b ]噻唑衍生物的酰胺部分来调节SIRT1酶的活性。该系列中最有效的类似物,即化合物29,已在ob / ob小鼠模型,饮食诱发的肥胖(DIO)小鼠模型和Zucker fa / fa大鼠模型中证明了口服降糖活性。
Dihydropyridines bearing an imidazo[2,1-b]thiazole system
摘要:
This paper reports the synthesis of imidazo[2,1-b]thiazoles, bearing a dihydropyridine ring at the 5 or 6 position, which were tested for antiarrhythmic, inotropic and chronotropic activities. Nine of the ten compounds bearing double bond at the 2,3 position and the same dihydropyridine as nifedipine at the 5 position, were antiarrhythmic; moreover one of them (bearing a methyl group at the 2 position) was devoid of negative inotropic activity.
