  Compounds with nanomolar potency versus Plasmodium DHODH and Plasmodium parasites were identified with good pharmacological properties. X-ray studies showed that the pyrroles bind an alternative enzyme conformation from 1 leading to improved species selectivity versus mammalian enzymes and equivalent activity on Plasmodium falciparum and Plasmodium vivax DHODH. The best lead DSM502 (37) showed in vivo efficacy

  疟疾使世界上近一半的人口面临风险，并导致撒哈拉以南非洲地区的高死亡率，而耐药性也威胁着现有的治疗方法。根据我们的发现，三唑并嘧啶 DSM265 (1) 在临床研究中显示出疗效，嘧啶生物合成酶二氢乳清酸脱氢酶 (DHODH) 是疟疾治疗的有效靶点。在此，我们描述了使用基于目标的 DHODH 筛选鉴定的基于吡咯的系列的优化。与疟原虫 DHODH 和疟原虫寄生虫相比具有纳摩尔效力的化合物已被鉴定具有良好的药理学特性。X 射线研究表明，吡咯与 1 的替代酶构象结合，从而提高了相对于哺乳动物酶的物种选择性，并且对恶性疟原虫和间日疟原虫 DHODH 具有同等活性。最好的先导 DSM502 (37) 在与 1 的血液暴露水平相似的情况下显示出体内功效，尽管代谢稳定性有所降低。总体而言，基于吡咯的 DHODH 抑制剂为新型抗疟化合物的开发提供了一种有吸引力的替代支架。

  amination of arene through C–H bond cleavage employing N-fluorobenzenesulfonimide (NFSI) as the amination reagent in good to excellent yields with broad arene scope in the absence of any metal, ligand or additive is reported. Unlike previous transition metal-catalysed aminations in which high reaction temperatures are usually necessary, this novel reaction at room temperature is the first example of C–H

  据报道，在不使用任何金属，配体或添加剂的情况下，使用N-氟苯磺酰亚胺（NFSI）作为胺化试剂，通过TEMP键催化的芳烃通过C–H键断裂的直接胺化反应具有良好的收率和优异的收率。与以前通常需要高反应温度的过渡金属催化胺化反应不同，这种在室温下的新颖反应是通过有机催化实现的NFSI的C–H胺化反应的第一个例子。还提出了这种简洁胺化的可能机理。

  pyrrole-based series of DHODH inhibitors, leading to the discovery of two candidates for potential advancement to preclinical development. These compounds have improved physicochemical properties over prior series frontrunners and they show no time-dependent CYP inhibition, characteristic of earlier compounds. Frontrunners have potent antimalarial activity in vitro against blood and liver schizont stages
