development of drug resistance in malaria-endemic countries. In this regard, histone deacetylases (HDACs) have emerged as new and promising malaria drug targets. In this work, we present the design, synthesis, and biological evaluation of 20 novel HDAC inhibitors with antiplasmodial activity. Based on a previously discovered peptoid-based hit compound, we modified all regions of the peptoid scaffold by using
鉴于疟疾流行国家耐药性的发展,新的疟疾干预策略非常重要。在这方面,组蛋白脱乙酰酶(HDAC)已成为新的、有前途的疟疾药物靶点。在这项工作中,我们介绍了 20 种具有抗疟原虫活性的新型 HDAC 抑制剂的设计、合成和生物学评价。基于之前发现的基于类肽的命中化合物,我们通过使用一锅多组分途径和亚单体途径修饰了类肽支架的所有区域,以更深入地了解结构-活性和结构-毒性关系。大多数化合物对无性血液期恶性疟原虫寄生虫表现出有效的活性,IC50值在0.0052-0.25μm范围内,并且对哺乳动物细胞具有良好的选择性(SIPf3D7/HepG2:170-1483)。此外,几种化合物对伯氏疟原虫外红细胞形式(PbEEF)表现出令人鼓舞的亚微摩尔活性。我们的研究发现了热门化合物 N-(2-(苄氨基)-2-氧代乙基)-N-(4-(羟基氨基甲酰基)苄基)-4-异丙基苯甲酰胺 (2 h) 作为一种有效的寄生虫特异性
