  摘要：

  粘着斑激酶 (FAK) 是一种酪氨酸激酶，在蛋白质支架、迁移、血管生成和不依赖锚定的细胞存活中具有重要作用，是开发癌症治疗药物的有吸引力的靶点。然而，目前的 FAK 抑制剂显示出双重激酶抑制和/或对几种激酶的显着活性。尽管多靶点活性有时在治疗上是有利的，但这种行为也可能导致毒性和混淆化学生物学研究。我们报告了一系列基于三环嘧啶并噻唑二氮杂酮核心的新型小分子，其对 FAK 显示出高效和选择性。构效关系 (SAR) 研究探索了对噻唑、二氮杂酮和苯胺“尾”的修饰，确定了先导化合物 BJG-03-025。50 = 20 nM)、出色的激酶组选择性、在 3D 培养乳腺癌和胃癌模型中的活性以及在小鼠中的良好药代动力学特性。BJG-03-025 是一种有价值的化学探针，用于评估 FAK 依赖性生物学。

  The dormant and resistant form of Mycobacterium tuberculosis presents a challenge in developing new anti-tubercular drugs. Herein, we report the synthesis and evaluation of trisubstituted thiazoles as antituberculosis agents. The SAR study has identified a requirement of hydrophobic substituent at C2, ester functionality at C4, and various groups with hydrogen bond acceptor character at C5 of thiazole

  结核分枝杆菌的休眠和耐药形式在开发新的抗结核药物方面提出了挑战。在此，我们报道了三取代噻唑类作为抗结核剂的合成和评价。SAR研究已经确定了噻唑支架在C2处具有疏水取代基，在C4处具有酯官能度以及在C5处具有氢键受体特性的各种基团的需求。这导致鉴定出13h和13p为先导化合物。这些化合物选择性地抑制了休眠的结核分枝杆菌H37Ra菌株和结核分枝杆菌H37Rv。重要的是，13h和13p对CHO细胞无毒。这13p显示出对耐多药结核病分离株的活性。
