confirmed that acid sphingomyelinase (ASM) activity is associated with depression. The discovery of direct inhibitors against ASM is of great significance for exploring antidepressants and their mechanisms of action. Herein, a series of novel phenylpyrazole analogues were rationally designed and synthesized. Among them, compound 46 exhibited potent inhibitory activity (IC50 = 0.87 μM) and good drug-like properties
多项研究已证实酸性鞘磷脂酶 (ASM) 活性与抑郁症相关。 ASM直接抑制剂的发现对于探索抗抑郁药物及其作用机制具有重要意义。本文合理设计并合成了一系列新型苯基吡唑类似物。其中,化合物46表现出有效的抑制活性(IC 50 = 0.87 μM)和良好的药物样特性。体内研究表明,化合物46参与多种抗抑郁作用机制,这些机制与神经酰胺的下降有关,包括增加 Bcl-2/Bax 比率和 BDNF 表达,下调 caspase-3 和 caspase-9,改善氧化应激,降低小鼠大脑中促炎细胞因子(如 TNF-α、IL-1β 和 IL-6)的水平,以及升高 5-HT 水平。这些有意义的结果首次揭示了直接抑制剂通过多种抗抑郁作用机制在 CUMS 诱导的小鼠模型中表现出显着的抗抑郁作用。
