  通过基于吡咯的二氢乳清酸脱氢酶抑制剂系列的结构引导计算优化鉴定出具有开发潜力的强效抗疟药

  摘要：

  二氢乳清酸脱氢酶（DHODH）已被临床验证为开发新型抗疟药的靶点。临床候选三唑并嘧啶 DSM265 的经验（1）表明 DHODH 抑制剂在预防方面具有巨大的潜力，这代表了流行国家的疟疾药物发现组合中未满足的需求，特别是在非洲高传播地区。我们描述了基于结构的计算驱动的基于吡咯的一系列 DHODH 抑制剂的先导化合物优化程序，从而发现了两种可能推进临床前开发的候选药物。这些化合物比之前系列的领跑者具有更好的物理化学性质，并且它们没有显示出早期化合物所特有的时间依赖性 CYP 抑制作用。Frontrunners在体外对血液和肝脏裂殖期具有有效的抗疟活性，并且对恶性疟原虫表现出良好的疗效SCID 小鼠模型。它们对恶性疟原虫和间日疟原虫野外分离株具有同样的活性，并且对疟原虫DHODH 与哺乳动物酶具有选择性。

  Synthesis and pharmacological evaluation of N-benzyl substituted 4-bromo-2,5-dimethoxyphenethylamines as 5-HT2A/2C partial agonists

  摘要：

  N-Benzyl substitution of phenethylamine 5-HT2A receptor agonists has dramatic effects on binding affinity, receptor selectivity and agonist activity. In this paper we examine how affinity for the 5-HT2A/2C receptors are influenced by N-benzyl substitution of 4-bromo-2,5-dimethoxyphenethylamine derivatives. Special attention is given to the 2' and 3'-position of the N-benzyl as such compounds are known to be very potent. We found that substitutions in these positions are generally well tolerated. The 2'-position was further examined using a range of substituents to probe the hydrogen bonding requirements for optimal affinity and selectivity, and it was found that small changes in the ligands in this area had a profound effect on their affinities. Furthermore, two ligands that lack a 2'-benzyl substituent were also found to have high affinity contradicting previous held notions. Several high-affinity ligands were identified and assayed for functional activity at the 5-HT2A and 5-HT2C receptor, and they were generally found to be less efficacious agonists than previously reported N-benzyl phenethylamines.

  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
