A series of 5-(4-alkoxyphenylalkyl)-1H-tetrazole derivatives, containing an oxazole-based group at the alkoxy moiety, was prepared and their antidiabetic effects were evaluated in two genetically obese and diabetic animal models, KKAy mice and Wistar fatty rats. Syntheses were performed by cyclization of the corresponding nitriles reacting with azide compounds. A large number of the 5-(4-alkoxyphenylalkyl)-1H-tetrazoles showed potent glucose and lipid lowering activities in KKAy mice. In particular, 5-[3-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-3-pyridyl]propyl]-1H-tetrazole had potent glucose lowering activity (ED25=0.0839 mg⋅kg−1⋅d−1), being 72 times more active than pioglitazone hydrochloride (ED25=6.0 mg⋅kg−1⋅d−1). This compound also showed strong glucose lowering (ED25=0.0873 mg⋅kg−1⋅d−1) and lipid lowering effects (ED25=0.0277 mg⋅kg−1⋅d−1) in Wistar fatty rats. The antidiabetic effects of this compound are considered to be due to its potent agonistic activity for peroxisome proliferator-activated receptor γ (PPARγ) (EC50=6.75 nM).
合成了一系列含有噁唑基团的5-(4-烷氧基苯基烷基)-1H-四唑衍生物,并在两种遗传性肥胖和糖尿病动物模型(KKAy小鼠和Wistar肥胖大鼠)中评估了它们的抗糖尿病效果。合成是通过相应的腈与叠氮化合物反应环化进行的。大量的5-(4-烷氧基苯基烷基)-1H-四唑在KKAy小鼠中显示出强大的降血糖和降脂活性。特别是5-[3-[6-(5-甲基-2-苯基-4-噁唑基甲氧基)-3-吡啶基]丙基]-1H-四唑显示出强大的降血糖活性(ED25=0.0839 mg⋅kg−1⋅d−1),比盐酸吡格列酮(ED25=6.0 mg⋅kg−1⋅d−1)活性高出72倍。该化合物在Wistar肥胖大鼠中也显示出强大的降血糖(ED25=0.0873 mg⋅kg−1⋅d−1)和降脂效果(ED25=0.0277 mg⋅kg−1⋅d−1)。该化合物的抗糖尿病效果被认为是因为它对过氧化物酶体增殖物激活受体γ(PPARγ)具有强大的激动活性(EC50=6.75 nM)。
