  have led to the discovery of several potent inhibitors; however, so far no highly selective type-II inhibitors have been reported. We previously identified VPC-00628 as a potent and selective type-II inhibitor of p38α/β with few off-targets. Here we analyzed the chemical building blocks of VPC-00628 that played a key role in achieving potency and selectivity through targeting an inactive state of the

  p38丝裂原活化的蛋白激酶是环境应激反应的关键介质，并且是治疗炎症性疾病和癌症的有希望的靶标。大量的努力导致发现了几种有效的抑制剂。然而，到目前为止，还没有报道高选择性的II型抑制剂。我们先前将VPC-00628确定为p38α/β的有效且选择性的II型抑制剂，几乎没有脱靶现象。在这里，我们分析了VPC-00628的化学结构单元，这些结构单元通过靶向由独特的折叠P环构象诱导的激酶的非活性状态，在实现效能和选择性方面发挥了关键作用。使用快速，系统的组合合成方法，我们确定了化合物93（SR-318）对p38α/β具有极强的效力和选择性，可有效抑制全血中TNF-α的释放。因此，SR-318提供了一种有效的，选择性的p38α/βII型抑制剂，可用作化学探针，用于靶向这两种p38同工型的特定非活性状态。

  The identification of novel Topoisomerase II (Topo II) inhibitors is one of the most attractive directions in the field of bactericide research and development. In our ongoing efforts to pursue the class of inhibitors, six series of 70 novel coumarin-pyrazole carboxamide derivatives were designed and synthesized. As a result of the evaluation against four destructive bacteria, including Staphylococcus

  新型拓扑异构酶II（Topo II）抑制剂的鉴定是杀菌剂研究和开发领域中最有吸引力的方向之一。在我们寻求抑制剂的不断努力中，设计并合成了六种系列的70种新的香豆素-吡唑羧酰胺衍生物。作为针对四种破坏性细菌的评估结果，包括金黄色葡萄球菌，单核细胞增生性李斯特菌，大肠杆菌和沙门氏菌。与环丙沙星（MIC = 0.5 mg / L）相比，化合物8III-k（MIC = 0.25 mg / L）显示出对大肠杆菌和8V-c的显着抑制活性（MIC = 0.05 mg / L）对沙门氏菌表现出比环丙沙星（MIC = 0.25 mg / L）优异的抗菌活性。所选化合物（8III-k，8V-c和8V-k）表现出对Topo II和Topo IV的有效抑制作用，IC 50值为（9.4-25 mg / L）。分子对接模型表明，化合物8V-c和8V-k可以通过与氨基酸残基相互作用而与靶标良好结合。它将为商业Topo II抑菌剂提供一些有价值的信息。
