series of novel isoflavone/benzo-δ-sultam hybrids was synthesised and evaluated as potential anti-inflammatory and neuroprotective drugs in LPS-activated BV2 microglia. The benzo-δ-sultam core was constructed in a two-step reaction by coupling 2-halobenzenesulfonamide derivatives with terminal alkynes, followed by a 6-endo-dig cyclisation. The synthesised compounds, including precursors and hybrids, were
合成了少量的新型异黄酮/苯并-δ-sultam杂种,并将其评估为LPS激活的BV2小胶质细胞中潜在的抗炎和神经保护药物。通过将2-卤代苯磺酰胺衍生物与末端炔烃偶联,然后进行6-endo-dig环化反应,可在两步反应中构建苯并-δ-sultam核。测试了合成的化合物(包括前体和杂化物)在LPS刺激的BV2小胶质细胞中抑制NO和TNF-α产生的能力,结果令人鼓舞。在孔中最终浓度为20 µM时,最有效的杂种可将NO生成量降低至41%,将TNF-α降低至34%。
