醛糖还原酶(ALR2)抑制剂为对抗糖尿病并发症提供了一种可行的模式。ALR2在活动部位附近表现出可塑性,并且在附近的两个支撑α螺旋中可能发生位移。因此,在天然异黄酮的基础上,设计并合成了一系列新的色烯-3-咪唑(13-15)的氨基酸缀合物。根据光谱数据(1 H NMR,13 C NMR和MS)鉴定化合物,并在体外测试ALR2抑制活性,IC 50值范围为0.031± 0.082μM至4.29±0.55μM。我们的计算机和生化研究证实了15e在对醛还原酶(ALR1)具有高选择指数的合成化合物中,具有最佳的抑制活性。向STZ诱导的大鼠补充15e可以降低血糖水平,并以剂量依赖性方式延缓白内障的进展。因此,本研究提供了具有希望的抑制剂以预防或延缓白内障进展的一系列新化合物。

The present invention discloses compounds or pharmaceutically acceptable salts, esters, or prodrugs thereof, which inhibit RNA-containing virus, particularly the hepatitis C virus (HCV). Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.

Aldosereductase (ALR2) inhibitors provide a viable mode to fight against diabetic complications. ALR2 exhibit plasticity in the active site vicinities and possible shifts in the nearby two supporting alpha helices. Therefore, a novel series of amino acid conjugates of chromene-3-imidazoles (13–15) were designed and synthesized based on natural isoflavonoids. The compounds were identified on the basis
