After preliminary ab initio calculations, 3-phenacyl substituted thiazolium salts, analogs of Alagebrium, were synthesized and investigated in vitro as glycation reaction inhibitors. The most part of investigations focused on the potential of the title compounds to attenuate the formation of fluorescent AGEs as well on their ability to disrupt the cross-linking formation among glycated proteins.

经过初步的从头计算,合成了 3-苯甲酰基取代的噻唑鎓盐(Alagebrium 的类似物),并在体外作为糖化反应抑制剂进行了研究。大部分研究集中在标题化合物减弱荧光 AGE 形成的潜力以及它们破坏糖化蛋白之间交联形成的能力。此外,还测定了噻唑鎓盐在早期糖基化产物与硝基蓝四唑的反应中去糖化的能力。使用 LDH 和 MTT 测定评估标题化合物的细胞毒理学性质。 50 mg/kg 剂量(口服 14 天)的先导化合物(3-[2-(联苯-4-基)-2-氧代乙基]-1,3-噻唑-3-溴化鎓)在体内羰基应激模型(大鼠,甲基乙二醛 86.25 mg/kg/d,腹腔注射,14 天)。结果,该前导分子在体外测试中显示出对所有三种糖化反应抑制机制的高效作用,并且能够抑制甲基乙二醛在体内形成 AGE 的能力。
