palmitoyltransferases (CPTs) as a representative class of enzymes as potential targets for metabolic chokepoint intervention that was elucidated from a combination of chemogenomic screening and experimental testing in nematodes. Expanding on these previous findings, we have discovered that several chemical classes of known small molecule inhibitors of mammalian CPTs have potent activity as anthelmintics
在世界范围内,由寄生线虫引起的大量感染,加上它们对常用驱虫药的抗性迅速出现,迫切需要发现新药。在本文中,我们确定了几类对这些病原体具有广谱活性的小分子。以前,我们报道了肉毒碱棕榈酰转移酶(CPTs)作为代表性代表的一类酶,它们是代谢扼流点干预的潜在目标,这一点已通过化学基因组学筛选和线虫实验测试的结合加以阐明。在扩展这些先前发现的基础上,我们发现,已知几种化学类别的哺乳动物CPT的小分子抑制剂具有有效的驱虫药活性。对于来自不同系列的多种化合物,证明了其对多种成虫寄生线虫的跨谱疗效。设计并合成了这些初始命中化合物的几种类似物。我们报告的化合物为进一步鉴定和优化开发具有广谱活性和新作用机制的新型驱虫药提供了一个良好的起点。
