anti-depressant, and anti-tumor effects. In this study, we aim to reduce in vivo and in vitro toxicity of compound 32 (preliminary work) and maintain its biological activity. A series of novel pterostilbene derivatives (D1-D43) were designed and synthesized, and their anti-inflammatory activities were screened. All compounds were screened to evaluate their inhibitory effect on LPS/Nigericin-induced
紫檀芪骨架是一种很有前途的化学支架,具有抗炎、抗抑郁和抗肿瘤作用。在本研究中,我们旨在降低化合物 32 的体内和体外毒性(初步工作)并保持其生物活性。设计合成了一系列新的紫檀芪衍生物(D1 - D43),并筛选了它们的抗炎活性。筛选所有化合物以评估它们对 LPS/Nigericin 诱导的 IL-1β 产生和细胞焦亡的抑制作用。推导出构效关系,最终得到1-(( E )-4-(2-乙氧基乙氧基)苯乙烯基)-3,5-二甲氧基-2-(( E )-2-硝基乙烯基)苯( D22) 被发现是一种具有最有效抑制功效的低毒化合物(针对 IL-1β:IC 50 =2.41 μM)。初步机制研究表明,化合物D22可能通过靶向NLRP3蛋白影响NLRP3炎性小体的组装,从而抑制NLRP3炎性小体的激活。体内抗炎活性表明化合物D22对DSS诱导的小鼠急性结肠炎模型具有显着的治疗作用。
