  Ethionamide Boosters. 2. Combining Bioisosteric Replacement and Structure-Based Drug Design To Solve Pharmacokinetic Issues in a Series of Potent 1,2,4-Oxadiazole EthR Inhibitors

  摘要：

  Mycobacterial transcriptional repressor EthR controls the expression of EthA, the bacterial monooxygenase activating ethionamide, and is thus largely responsible for the low sensitivity of the human pathogen Mycobacterium tuberculosis to this antibiotic. We recently reported structure-activity relationships of a series of 1,2,4-oxadiazole EthR inhibitors leading to the discovery of potent ethionamide boosters. Despite high metabolic stability, pharmacokinetic evaluation revealed poor mice exposure; therefore, a second phase of optimization was required. Herein a structure-property relationship study is reported according to the replacement of the two aromatic heterocycles: 2-thienyl and 1,2,4-oxadiazolyl moieties. This work was done using a combination of structure-based drug design and in vitro/ex vivo evaluations of ethionamide boosters on the targeted protein EthR and on the human pathogen Mycobacterium tuberculosis. Thanks to this process, we identified compound 42 (BDM41906), which displays improved efficacy in addition to high exposure to mice after oral administration.

  piperidine-derived trisubstituted ureas are reported as highly potent and selective inhibitors for sEH. The SAR outlines approaches to improve activity against sEH and reduce ion channel and CYP liability. With minimal off-target activity and a good PK profile, the benchmark 2d exhibited remarkable in vitro and ex vivo target engagement. The eutomer entA-2d also elicited vasodilation effect in rat mesenteric

  据报道，4-取代的哌啶衍生的三取代脲是sEH的高效抑制剂。SAR概述了提高抗sEH活性并减少离子通道和CYP危害的方法。具有最小的脱靶活性和良好的PK分布，基准2d表现出了卓越的体外和离体靶标参与。Eutomer ent A - 2d也引起大鼠肠系膜动脉的血管舒张作用。
