Condensed polycyclic heteroaromatic cations bearing a bridgehead nitrogen with pyridazino[1′,6′:1,2]pyrido[3,4-b]indolinium and pyridazino[1,6-a]benzimidazolium structures were assayed as inhibitors of LPS-induced TNF-α production by THP-1 cells. The hit compound 1e, which had the best IC50 value (4.49 μM) and low toxicity, was further assayed on human PMBCs (IC50 3.91 μM) and monocytes (IC50 1.82 μM)
稠合多环杂芳族阳离子轴承与哒嗪并一个桥头氮[1',6':1,2]吡啶并[3,4 b ]二氢吲哚和哒嗪并[1,6-一个]苯并咪唑的结构进行测定作为LPS诱导的TNF的抑制剂THP-1细胞产生-α。具有最佳IC 50值(4.49μM)和低毒性的命中化合物1e在人PMBC(IC 50 3.91μM )和单核细胞(IC 50 1.82μM)上进一步测定。在人单核细胞和单核细胞衍生的树突状细胞的多聚I:C刺激后,该化合物还抑制TNF-α的产生。在后一种情况下,也观察到了IL-12产生的抑制。化合物1e还在转录水平上抑制TNF-α的表达,并在体内被证明是有效的。化合物1e是IMID中令人感兴趣的潜在治疗剂。
