  lymphoid tissue lymphoma translocation protein 1 (MALT1) inhibitors is of great value and significance in the treatment of neoplastic disorders and inflammatory and autoimmune diseases. However, there is a lack of effective MALT1 inhibitors in clinic. Herein, a novel class of potent 5-oxo-1-thioxo-4,5-dihydro-1H-thiazolo[3,4-a]quinazoline-based MALT1 inhibitors and their covalent derivatives were first identified

  黏膜相关淋巴组织淋巴瘤易位蛋白 1 (MALT1) 抑制剂的开发在肿瘤性疾病、炎症和自身免疫性疾病的治疗中具有重要价值和意义。然而，临床上缺乏有效的MALT1抑制剂。在此，首次通过高通量鉴定和设计了一类新型有效的 5-oxo-1-thioxo-4,5-dihydro-1 H - thiazolo[3,4- a ]quinazoline 抑制剂及其共价衍生物。筛选。我们证明了化合物15c、15e和20c有效抑制 MALT1 蛋白酶并对活化的 B 细胞样弥漫性大 B 细胞淋巴瘤具有低个位数微摩尔效力显示出选择性细胞毒性。此外，化合物20c以剂量依赖性方式特异性抑制 MALT1 依赖性 TMD8 细胞中的 NF-κB 信号传导并诱导细胞凋亡。更重要的是，20c在 TMD8 异种移植肿瘤模型中显示出良好的药代动力学特性和抗肿瘤功效，且无显着毒性。总的来说，这项研究为 MALT1 抑制剂的进一步结构
• Reductive Ring Closure Methodology toward Heteroacenes Bearing a Dihydropyrrolo[3,2-<i>b</i>]pyrrole Core: Scope and Limitation

  reductive ring closure methodology to heteroacenes bearing a dihydropyrrolo[3,2-b]pyrrole core was systematically studied for its scope and limitation. The methodology involves (i) the cyclization of an o-aminobenzoic acid ester derivative to give an eight-membered cyclic dilactam, and (ii) the conversion of the dilactams into the corresponding diimidoyl chloride, which undergoes (iii) reductive ring closure

  针对其具有范围和局限性，系统地研究了一种新开发的带有二氢吡咯并[3,2- b ]吡咯核的杂环丁烷的还原性闭环方法。该方法涉及（i）邻氨基苯甲酸酯衍生物的环化以产生八元环状双内酰胺，和（ii）将双内酰胺转化成相应的二亚氨基酰氯，其经历（iii）还原性闭环以安装二氢吡咯并[3,2- b]吡咯核。该方法的第一步由于其底物限制而起关键作用，该底物受到低聚和水解竞争的困扰。所有的双内酰胺都可以成功地转化为相应的二亚氨基氯化物，其中大多数成功地得到了二氢吡咯并[3,2- b]吡咯核。然后使用紫外-可见光谱和循环伏安法系统地研究了取代基和共轭长度的延长对所得杂苯的光物理性质的影响。发现氯化和氟化对杂并苯的光物理性质有很大不同的影响，并且环熔合样式也对杂并苯的带隙有很大的影响。成功地制备一系列带有二氢吡咯并[3，2- b ]吡咯核的杂并苯将为进一步制造有机场效应晶体管器件提供各种各样的候选物。
