injury, multiple sclerosis, cardiovascular and neurodegenerative diseases. Therefore, the enzyme currently draws attention as a potential therapeutic target. In this study, isomeric 1,3-dihydro-2H-benzo[d]imidazole-2-thione derivatives having amide, hydrazide and hydroxamic acid groups either on nitrogen or on sulphur atom were designed and their inhibitory activity was determined on chlorination and peroxidation
髓过氧化物酶 (MPO) 通过产生的次氯酸 (HOCl) 氧化吞噬溶酶体中微生物的重要分子,从而在人体抗菌系统中发挥关键作用。然而,MPO 可以释放到吞噬细胞外并产生反应性中间体,导致组织损伤。MPO 作为组织损伤的局部介质,与肾损伤、多发性硬化、心血管和神经退行性疾病等炎症性疾病有关。因此,该酶目前作为潜在的治疗靶点而备受关注。在这项研究中,同分异构的 1,3-dihydro-2 H -benzo[ d设计了在氮原子或硫原子上具有酰胺、酰肼和异羟肟酸基团的咪唑-2-硫酮衍生物,并测定了它们对 MPO 的氯化和过氧化循环的抑制活性。在这些化合物中,2-(2-thioxo-2,3-dihydro-1H-benzo[d]imidazole -1-yl )acetohydrazide (C19)被发现是两个循环中最活跃的抑制剂。
