Thioxo-dihydroquinazolin-one Compounds as Novel Inhibitors of Myeloperoxidase
摘要:
Myeloperoxidase (MPO) is a key antimicrobial enzyme, playing a normal role in host defense, but also contributing to inflammatory conditions including neuroinflammatory diseases such as Parkinson's and Alzheimer's. We synthesized and characterized more than 50 quinazolin-4(1H)-one derivatives and showed that this class of compounds inhibits MPO with IC50 values as low as 100 nM. Representative compounds showed partially reversible inhibition that was competitive with respect to Amplex Red substrate and did not result in the accumulation of MPO Compound II. Members of this group show promise for therapeutic development for the treatment of diseases in which inflammation plays a pathogenic role.
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 MALT1inhibitors in clinic. Herein, a novel class of potent 5-oxo-1-thioxo-4,5-dihydro-1H-thiazolo[3,4-a]quinazoline-based MALT1inhibitors 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
