The NF-κB signaling pathway is a validated oncological target. Here, we applied scaffold hopping to IMD-0354, a presumed IKKβ inhibitor, and identified 4-hydroxy--[3,5-bis(trifluoromethyl)phenyl]-1,2,5-thiadiazole-3-carboxamide () as a nM-inhibitor of the NF-κB pathway. However, both and IMD-0354, being potent inhibitors of the canonical NF-κB pathway, were found to be inactive in human IKKβ enzyme assays.
核因子-κB(NF-κB)信号通路是一个经过验证的肿瘤学靶点。在此,我们对假定的IKKβ抑制剂IMD-0354进行了骨架跃迁,并鉴定出4-羟基--[3,5-双(三氟甲基)苯基]-1,2,5-噻二唑-3-甲酰胺()作为NF-κB通路的纳摩尔级抑制剂。然而,发现 和IMD-0354作为经典NF-κB通路的强效抑制剂,在人IKKβ酶检测中均无活性。
