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
