  4-Aminopyridyl-Based CYP51 Inhibitors as Anti-Trypanosoma cruzi Drug Leads with Improved Pharmacokinetic Profile and in Vivo Potency

  摘要：

  CYP51 is a P450 enzyme involved in the biosynthesis of the sterol components of eukaryotic cell membranes. CYP51 inhibitors have been developed to treat infections caused by fungi, and more recently the protozoan parasite Trypanosoma cruzi, the causative agent of Chagas disease. To specifically optimize drug candidates for T. cruzi CYP51 (TcCYP51), we explored the structure activity relationship (SAR) of a N-indolyl-oxopyridinyl-4-aminopropanyl-based scaffold originally identified in a target-based screen. This scaffold evolved via medicinal chemistry to yield orally bioavailable leads with potent anti-T. cruzi activity in vivo. Using an animal model of infection with a transgenic T. cruzi Y luc strain expressing firefly luciferase, we prioritized the biaryl and N-arylpiperazine analogues by oral bioavailability and potency. The drug target complexes for both scaffold variants were characterized by X-ray structure analysis. Optimization of both binding mode and pharmacokinetic properties of these compounds led to potent inhibitors against experimental T. cruzi infection.

  摘要：

  该发明提供了一种甾醇C14-去甲基酶的抑制剂，这是一种新系列基于4-氨基吡啶的首选抑制剂，通过基于结构的药物设计以及结构-性质关系（SPR）分析来瞄准Trypanosoma cruzi CYP51（TcCYP51）而开发的。筛选起始点LP 10（KD < 42 nM；EC50为0.65 μΜ）已经经过优化，产生了具有低纳摩尔级别结合亲和力和对在人类肌细胞培养的T. cruzi游离体的显著活性的潜在首选抑制剂。许多经过优化的化合物具有改善的微粒体稳定性，大多数相对于人类CYPs 1A2、2D6和3A4对T. cruzi CYP51具有选择性（在1 μΜ下<50%的抑制）。提出了改善微粒体稳定性和抑制剂对人类代谢CYP酶的选择性的理由。此外，通过X射线结构分析表征了该发明的几种化合物与T. brucei CYP51（TbCYP51）同源物的结合方式。口服活性化合物及其环糊精复合物已被证明对克氏病感染的小鼠有效。

  Sterol 14 alpha-demethylase (CYP51) is an important therapeutic target for fungal and parasitic infections due to its key role in the biosynthesis of ergosterol, an essential component of the cell membranes of these pathogenic organisms. We report the development of potent and selective D-tryptophan-derived inhibitors of T. cruzi CYP51. Structural information obtained from the cocrystal structure of CYP51 and (R)-2, which is >1000-fold more potent than its enantiomer (S)-1, was used to guide design of additional analogues. The in vitro efficacy data presented here for (R)-2 (R)-8, together with preliminary in vitro pharmacokinetic data suggest that this new CYP51 inhibitor scaffold series has potential to deliver drug candidates for treatment of T. cruzi infections.
