基于阻断IL-6/STAT信号通路的全新小檗碱衍生物的设计、合成及其抗炎作用评价

Design, synthesis and evaluation of anti-inflammatory effect of novel berberine derivatives on IL-6/STAT signaling pathway

  • 摘要: 白介素-6(IL-6)/转录激活因子(STAT)信号通路的活化与动脉粥样硬化(AS)的发生发展密切相关。本研究以我国天然产物单体盐酸小檗碱(BBR)为先导物,通过在其3-位或/和9-位引入不同类型的侧链基团,设计合成了一系列全新结构BBR衍生物,并对其抑制IL-6诱导的STAT1/3的磷酸化进行了评价。构效关系表明,3-位或9-位引入刚性结构有利于活性提高,其中,化合物2b9显示出最优的抑制活性。进一步研究提示,化合物2b9通过激活HUVEC细胞中AMPK活性,抑制IL-6诱导的STAT1和STAT3磷酸化。研究结果显示,BBR衍生物通过AMPK途径抑制IL-6/STAT信号通路介导的炎症反应,为此类化合物发展成为抗AS候选物提供了有益的科学数据。

     

    Abstract: Interleukin-6 (IL-6)/signal transducers and activators of transcription (STAT) signaling pathway is closely related to the development and progression of atherosclerosis (AS). Taking Chinese natural product berberine (BBR) as the leading compound, a series of novel BBR analogues defined on different types of substituents on position 3 or/and 9 were designed, synthesized and evaluated for their inhibitory activities on phosphorylation of STAT-1 and STAT-3 induced by IL-6. The structure-activity relationship indicated that introduction of rigid fragment on position 3 or 9 was beneficial for enhancing their activities. Among them, compounds 2b and 9 exhibited the most satisfactory potency. The study revealed that the compounds 2b and 9 exhibit anti-inflammatory potencies via activating AMPK, and down-regulation of phosphorylation of STAT1 and STAT3 induced by IL-6 in HUVEC cells. These results suggest that BBR derivatives may inhibit the inflammatory response mediated by the IL-6/STAT signaling pathway through regulation of AMPK, which provides useful insight into the development of BBR derivatives for treatment of atherosclerosis.
