interleukin-6 (IL-6) levels in RAW 264.7 cells induced by lipopolysaccharide (LPS). The findings of this study were further explained in light of network pharmacology analysis which suggested that AChE and nitric oxide synthase were the main targets of the most active compounds. Molecular docking studies revealed their ability to bind to the heme binding site of nitric oxide synthase 3 (NOS-3) and effectively
在这项研究中,我们研究了茶碱与不同天然来源化合物的缀合,希望构建具有抗胆碱能和炎症途径双重活性的新杂合体,作为治疗阿尔茨海默病(AD)的潜在药物。与加兰他敏标准 AChE 抑制剂相比,在 28 个测试的杂合体中,两种杂合体(乙酰茶碱-丁香酚 6d 和乙酰胆碱-靛红 19)能够以低微摩尔浓度抑制乙酰胆碱酯酶 (AChE),IC50 值分别为 1.8 和 3.3 μM 。此外,制备的杂交体对RAW 264.7中脂多糖诱导的炎症表现出显着的抗炎作用,并减少一氧化氮(NO)、肿瘤坏死α(TNF-α)、白介素-1β(IL-1β)和白介素-6( IL-6)水平以剂量依赖性方式。这些杂交体表现出脂多糖 (LPS) 诱导的 RAW 264.7 细胞中一氧化氮 (NO)、肿瘤坏死 α (TNF-α)、白细胞介素 1β (IL-1β) 和白细胞介素 6 (IL-6) 水平显着降低。根据网络药理学分析进一步解释
