Berberine owns multiple pharmacological activities, especially anti-inflammatory activity. To enhance the anti-inflammatory therapeutic efficiency of berberine, a series of novel 9-O-substituted berberine derivatives (5a–5d) were synthesized and their anti-inflammatory activities were evaluated. 13C-NMR, 1H-NMR, IR and high resolution mass spectrum (HRMS) results indicated that these derivatives were
小ber碱具有多种药理活性,尤其是抗炎活性。为了提高小ber碱的抗炎治疗效果,合成了一系列新型的9- O-取代的小ber碱衍生物(5a - 5d),并评估了它们的抗炎活性。13 C-NMR,11 H-NMR,IR和高分辨率质谱(HRMS)结果表明这些衍生物已成功合成。二甲苯诱导的炎症小鼠模型表明,这些衍生物显示出剂量依赖性的耳炎性肿胀抑制作用。与小ber碱相比,布洛芬和萘普生修饰的小ber碱衍生物增强了抗炎活性,而阿司匹林和烟酸修饰的小ber碱衍生物在相同剂量下显示出较低的抗炎作用。这可能归因于布洛芬和萘普生小ber碱衍生物对细胞因子包括白介素6和肿瘤坏死因子-α分泌的抑制作用增强,而阿司匹林和烟酸小ber碱衍生物对肿瘤坏死因子-α的抑制作用比小ber碱低。
