Previous studies have shown that small molecule inhibitors of NLRP3 may be a potential treatment for Parkinson's disease (PD). NACHT, LRR and PYD domains-containing protein 3 (NLRP3), heat shock protein HSP 90-beta (HSP90AB1), caspase-1 (CASP1) and cellular tumor antigen p53 (TP53) have significant involvement in the pathogenesis pathway of PD. Molecular docking was used to screen the traditional Chinese medicine database TCM Database@Taiwan. Top traditional Chinese medicine (TCM) compounds with high affinities based on Dock Score were selected to form the drug-target interaction network to investigate potential candidates targeting NLRP3, HSP90AB1, CASP1, and TP53 proteins. Artificial intelligence model, 3D-Quantitative Structure-Activity Relationship (3D-QSAR) were constructed respectively utilizing training sets of inhibitors against the four proteins with known inhibitory activities (pIC). The results showed that 2007_22057 (an indole derivative), 2007_22325 (a valine anhydride) and 2007_15317 (an indole derivative) might be a potential medicine formula for the treatment of PD. Then there are three candidate compounds identified by the result of molecular dynamics.
先前的研究表明,NLRP3的小分子抑制剂可能是治疗帕金森病(PD)的一种潜在疗法。含NACHT、LRR和PYD结构域的蛋白3(NLRP3)、热休克蛋白HSP 90-β(HSP90AB1)、半胱天冬酶-1(CASP1)和细胞肿瘤抗原p53(TP53)在PD的发病机制途径中具有重要作用。利用分子对接技术筛选了台湾中医药数据库。根据对接分数选择具有高亲和力的顶级中药化合物,构建药物-靶点相互作用网络,以研究靶向NLRP3、HSP90AB1、CASP1和TP53蛋白的潜在候选物。分别利用针对四种具有已知抑制活性(pIC)的蛋白质的抑制剂训练集构建人工智能模型、三维定量构效关系(3D-QSAR)。结果表明,2007_22057(一种吲哚衍生物)、2007_22325(一种缬氨酸酐)和2007_15317(一种吲哚衍生物)可能是治疗PD的潜在药物配方。然后通过分子动力学结果鉴定出三种候选化合物。
