  Novel Peptidomimetic Cysteine Protease Inhibitors as Potential Antimalarial Agents

  摘要：

  The synthesis of a new class of peptidomimetics 1a-j, based on a 1,4-benzodiazepine scaffold and on a C-terminal aspartyl aldehyde building block, is described. Compounds 1a-j provided significant inhibitory activity against falcipains 2A and 2B (FP-2A and FP-2B), two cysteine proteases from Plasmodium falciparum.

  Tropolone emerged from the screening of a chelator fragment library (CFL) as an inhibitor of the Zn2+-dependent virulence factor, Pseudomonas aeruginosa elastase (LasB). Based on this initial hit, a series of substituted tropolone-based LasB inhibitors was prepared, and a compound displaying potent activity in vitro and in a bacterial swarming assay was identified. Importantly, this inhibitor was found to be specific for LasB over other metalloenzymes, validating the usage of tropolone as a viable scaffold for identifying first-in-class LasB inhibitors.

  曲贝酮在螯合剂片段文库(CFL)筛选中被发现是锌离子依赖的毒力因子铜绿假单胞菌弹性蛋白酶(LasB)的抑制剂。基于这个初始化合物，制备了一系列取代的曲贝酮类LasB抑制剂，并发现了一个在体外和细菌游动实验中显示出强效活性的化合物。重要的是，该抑制剂被发现对LasB具有特异性，而对其他金属酶没有作用，这验证了曲贝酮作为开发首创LasB抑制剂的可行支架。
