A series of N-substituted-1,2,3-triazole murrayafoline A derivatives were successfully synthesized using click azide–alkyne Huisgen cycloaddition reaction between 1-methoxy-3-methyl-9-(3-azido)-propyl-9H-carbazole and substituted alkynes. Their chemical structures were confirmed by 1H, 13C NMR and HR-ESI–MS spectral data. In addition, the interested effects on LPS-stimulated production of pro-inflammatory cytokines in bone marrow-derived dendritic cells of synthetic murrayafoline A derivatives were also investigated. Our results indicated that murrayafoline A derivatives containing 1,2,3-triazole nucleus potentially possessed anti-inflammatory action through inhibiting production of IL-6, IL-12 p40 and TNF-α.
一系列N取代的1,2,3-三唑穆拉亚福林A衍生物成功合成,采用点击反应的叠氮–炔烃胡斯根环加成反应,反应底物为1-甲氧基-3-甲基-9-(3-叠氮)-丙基-9H-咔唑和取代炔烃。其化学结构通过1H、13C NMR和高分辨率电喷雾质谱(HR-ESI–MS)数据得到确认。此外,我们还研究了合成的穆拉亚福林A衍生物对LPS刺激的骨髓来源树突状细胞中促炎细胞因子产生的影响。我们的结果表明,含有1,2,3-三唑核的穆拉亚福林A衍生物可能通过抑制IL-6、IL-12 p40和TNF-α的产生而具有抗炎作用。
