cells, making them appropriate targets for the treatment of diabetic retinopathy. To find the dual inhibitors of ALR2 and PARP-1, the structure based design was carried out in parallel for both the target proteins. A series of novel thiazolidine-2,4-dione (TZD) derivatives were therefore rationally designed, synthesized and their in vitro inhibitory activities against ALR2 and PARP-1 were evaluated
临床研究表明,糖尿病性视网膜病是一种多因素疾病。此外,研究还表明,ALR2和
PARP-1共同存在于视网膜细胞中,使其成为治疗糖尿病性视网膜病的合适靶标。为了找到ALR2和
PARP-1的双重
抑制剂,对两种靶蛋白并行进行了基于结构的设计。因此,合理设计,合成了一系列新型的
噻唑烷-
2,4-二
酮(TZD)衍
生物,并评估了它们对ALR2和
PARP-1的体外抑制活性。实验结果表明,具有2-
氯和4-
氟取代基的化合物5b和5f对两种目标酶均表现出微摩尔和亚微摩尔范围(IC501.34-5.03μM)的生化活性。阐明了针对这两种酶的新型
抑制剂的结构活性关系,为
抑制剂与酶活性位点的结合方式提供了新的认识。生化测定的阳性结果表明,可以进一步优化这些化合物并将其用于糖尿病性视网膜病的治疗。
