  喹唑啉作为细菌细胞分裂蛋白 FtsZ 抑制剂的合成和评价。

  摘要：

  细菌细胞分裂蛋白 FtsZ 是开发新型抗生素的众多潜在目标之一。最近，zantrin Z3 被证明是 FtsZ 的跨物种抑制剂；然而，它与蛋白质的特定相互作用仍然未知。在此，我们报告了包含更易处理的核心结构的类似物的合成，以及对 FtsZ 的 GTPase 活性具有个位数微摩尔抑制的类似物，这是迄今为止报道的最有效的大肠杆菌FtsZ抑制剂。此外，zantrin Z3 核心已转化为两种潜在的光交联试剂，用于蛋白质组学研究，可以阐明 FtsZ 与与 zantrin Z3 相关的分子之间的分子相互作用。

  aminobenzamides and in-situ generated aldehydes. Visible light was found to play a dual role: first oxidizes the alcohol to the aldehyde and then facilitates its cyclization with o-substituted aniline. Furthermore, alcohols are perfect alternatives to aldehydes because they are greener, more available, more economical, more stable, and less toxic than aldehydes. The first reaction step continuously

  Structure-activity relationship and crystallographic data revealed that quinazolinone-containing fragments flip between two distinct modes of binding to activin receptor-like kinase-2 (ALK2). We explored both binding modes to discover potent inhibitors and characterized the chemical modifications that triggered the flip in binding mode. We report kinase selectivity and demonstrate that compounds of

  tyrosine receptor kinase 3 (FLT3) is implicated in the pathogenesis of acute myeloid leukemia (AML) in 20-30% of patients. In this study we identified a highly selective (phenylethenyl)quinazoline compound family as novel potent inhibitors of the FLT3-ITD and FLT3-D835Y kinases. Their prominent effects were confirmed by biochemical and cellular proliferation assays followed by mice xenograft studies

  FMS样酪氨酸受体激酶3（FLT3）的异常激活与20-30％的患者的急性髓细胞性白血病（AML）的发病机制有关。在这项研究中，我们确定了高选择性（苯基乙烯基）喹唑啉化合物家族作为FLT3-ITD和FLT3-D835Y激酶的新型有效抑制剂。通过生化和细胞增殖测定以及随后的小鼠异种移植研究，证实了它们的显着效果。我们的建模实验和化合物的化学结构预测了共价抑制的可能性。最有效的化合物触发了FLT3-ITD AML细胞的凋亡，但在不依赖FLT3的白血病和非白血病细胞系中作用微弱或没有作用。
