  The invention provides new inhibitors of protein glycation, identified from compound libraries by a high throughput screening assay. The anti-glycation agents so identified are characterized by a variety of chemical structures and are useful for the prevention or treatment of age-, diabetes-, and smoking-related complications, including neuropathy, nephropathy, ocular pathologies, or the loss of mechanical properties of collagenous tissues. Among compounds identified as having the anti-glycation activity, of special interest are epinephrine and its analogs, in particular D-epinephrine and its analogs, which are particularly useful for the prevention or treatment of age-, diabetes-, and smoking-related ocular pathologies.

  这项发明提供了新的蛋白质糖基化抑制剂，通过高通量筛选检测从化合物库中鉴定出来。所鉴定的抗糖基化剂具有多种化学结构，可用于预防或治疗与年龄、糖尿病和吸烟有关的并发症，包括神经病变、肾病、眼部病理或胶原组织的机械性能丧失。在被鉴定为具有抗糖基化活性的化合物中，特别感兴趣的是肾上腺素及其类似物，特别是D-肾上腺素及其类似物，可用于预防或治疗与年龄、糖尿病和吸烟有关的眼部病理。
