  摘要：

  摘要 作为我们不断努力发现新型 c-Met 抑制剂作为抗肿瘤药物的一部分，我们设计、合成了四个系列的噻唑/噻二唑甲酰胺衍生类似物，并评估了其针对 c-Met 和四种人类癌细胞系的体外活性。经过五个周期的构效关系优化后，发现化合物51am在生化和细胞分析中都是最有前途的抑制剂。此外，51am对几种 c-Met 突变体表现出效力。从机制上讲，51am不仅诱导 MKN-45 细胞的细胞周期停滞和凋亡，而且抑制细胞和无细胞系统中的 c-Met 磷酸化。它还在 BALB/c 小鼠中表现出良好的药代动力学特征。此外， 51am与 c-Met 和 VEGFR-2 的结合模式为选择性 c-Met 抑制剂的发现提供了新的见解。总而言之，这些结果表明51am可能是值得进一步开发的抗肿瘤候选药物。

  摘要：

  在N1位含有新颖药效团的1,5-二芳基吡唑类类似物被设计、合成并对体外环氧合酶（COX-1/COX-2）抑制活性进行了评估。在C-5苯环的4位及其周围的变异与C-3位的CF3和CHF2基团结合，展现出高度的效力和选择性指数（SI），用于COX-2抑制。这些强效化合物的体内评估与先前的一些化合物相比，显示4-OMe-苯基类似物6和4-NHMe-苯基类似物9（C-3位含CF3），以及4-OEt-苯基类似物19（C-3位含CHF2）对COX-2的抑制效力超过了塞来昔布。除了出色的抗炎、解热、镇痛和抗关节炎特性外，化合物6（DRF-4367）被发现具有优秀的药代动力学特性，长期关节炎研究中的胃肠道安全性，以及在人体全血检测中的COX-2效力。因此，化合物6被选为口服活性的抗炎候选物进行临床前评估。

  DOI：10.1021/acs.joc.9b02876

  日期：2020.2.21

  A ball-milling-enabled zinc-mediated Barbier-type allylation reaction is reported. Notably, running the reaction in this manner renders it effective irrespective of the initial morphology of the zinc metal. The process is operationally simple, does not require inert atmospheres or dry solvents, and is reported over a range of aldehyde and ketone substrates; a gram-scale process is demonstrated.
