and PD. Herein, based on the combination principles, 23 of N-salicyloyl tryptamine derivatives as multifunctional agents were designed and their new application for anti-neuroinflammation was disclosed. In cyclooxygenase assay, two compounds 3 and 16 displayed extremely preferable COX-2 inhibition than N-salicyloyl tryptamine. In LPS-induced C6 and BV2 cell models, some compounds decreased the production
由于神经炎性过程的病因复杂,因此设计多功能药物是治疗包括AD和PD在内的神经炎性疾病的有效策略。在此,基于组合原理,设计了23种N-水杨酰类色胺衍生物作为多功能剂,并公开了其在抗神经炎症中的新应用。在环氧合酶测定中,两种化合物3和16表现出比N-水杨酰类色胺更高的COX-2抑制性。在LPS诱导的C6和BV2细胞模型中,某些化合物降低了促炎性介质NO,PGE 2,TNF-α,iNOS,COX-2和ROS的产生,同时增加了IL-10的产生。其中,化合物3和16结果表明,在C6中,一氧化氮的抑制作用比N-水杨酰色胺高约6倍。此外,化合物3,13和16衰减BV2和C6细胞的活化。更重要的是,在体内,化合物3和16降低海马中的GFAP和Iba-1水平,并在Nissl染色中显示出神经保护作用。此外,化合物3和16均具有较高的安全性(LD 50 > 1000 mg / kg)。化合物3和16的血浆半衰
