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 identify PfENR-specific inhibitors, we docked 70 FDA-approved, bioactive, and/or natural product small molecules known to inhibit the growth of whole-cell blood-stage P. falciparum into several PfENR crystallographic structures. Subsequent in vitro activity assays identified a noncompetitive low-micromolar PfENR inhibitor, celastrol, from this set of compounds.
烯酰-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,是抗恶性疟原虫肝细胞期药物研发的一个有前景的靶点。为了鉴定PfENR特异性抑制剂,我们将已知可抑制恶性疟原虫全细胞血液期生长的70种FDA批准的、具有生物活性的和/或天然产物小分子与几种PfENR晶体结构进行对接。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的低微摩尔浓度PfENR抑制剂——雷公藤红素。
