在相转移催化剂BnEt3N＋Br－作用下, 利用5-取代苯氧甲基-2-巯基-1,3,4-噻二唑与α-溴代四乙酰基吡喃糖室温反应, 合成了22个结构新颖的硫代糖苷类SGLT2抑制剂化合物, 结构经IR , 1H NMR, 13C NMR和HR-ESI-MS谱表征确认. 采用小鼠口服葡萄糖耐受量法测定了目标化合物在治疗糖尿病方面的活性, 结果发现化合物9Ah有明显的降糖作用, 而9Aa和9Bi与对照药物格列齐特相当.

22 thioglycosides with novel structure were designed and synthesized from 5-substituded phenyloxymethyl-2-mercapto-1,3,4-thiadiazole and tetra-O-acetyl-α-glycopyranosyl bromides in the presence of phase transfer catalysis (BnEt3N＋Br－) at room temperature. These compounds were characterized by IR, 1H NMR, 13C NMR, and HR-ESI-MS techniques. Bioactivity of decreasing blood glucose was performed through in vivo by oral glucose tolerance test (OGTT) in mice. In addition, preliminary pharmacological test showed that compound 9Ah was more potent than positive control gliclazide, while compounds 9Aa and 9Bi were comparable to gliclazide in potency.

Key words: thiadiazole, thioglycoside, SGLT2 inhibitor, synthesis, anti-hyperglycemic activity
