烯酰基载体蛋白还原酶 (ENR) 是 II 型脂肪酸生物合成中的关键酶,是抗肝细胞期恶性疟原虫药物开发的一个有前景的靶点。为了识别 PfENR 特异性抑制剂,我们对接了 70 个 FDA 批准的、生物活性的和/或天然产物小分子,这些小分子已知可抑制全细胞血液 P 期的生长。恶性疟原虫有几种 PfENR 晶体结构。随后的体外活性测定从这组化合物中鉴定出一种非竞争性低微摩尔 PfENR 抑制剂雷公藤红素。
Enoyl-acyl carrier protein reductase (ENR), a critical enzyme in type II fatty acid biosynthesis, is a promising target for drug discovery against hepatocyte-stage Plasmodium falciparum. In order to identifyPfENR-specific inhibitors, we docked 70 FDA-approved, bioactive, and/or natural product small molecules known to inhibit the growth of whole-cell blood-stageP. falciparuminto severalPfENR crystallographic structures. Subsequent in vitro activity assays identified a noncompetitive low-micromolarPfENR inhibitor, celastrol, from this set of compounds.
