  利用 TfOH 介导的酰亚胺羰基活化合成缩合四氢异喹啉类生物碱

  摘要：

  通过使用 TfOH 介导的（TfOH = 三氟甲磺酸）酰亚胺羰基活化和环化策略，从相应的酰亚胺成功组装了基于异喹啉的多环内酰胺，例如异吲哚异喹啉酮、吡咯并异喹啉酮和苯并 [a] 喹啉酮。通过使用这种简单的方法，异喹啉生物碱松脆 A、三乙醇胺/油茶素 E 和红菊素以外消旋形式成功合成。不对称 N-苯乙基邻苯二甲酰亚胺与 TfOH 的反应显示出优异的区域选择性，这通过 DFT 计算得到了合理化。

  isoindoloisoquinolinones, pyrroloisoquinolinones, and benzo[a]quinolizinones were successfully assembled from the corresponding imides by using a TfOH-mediated (TfOH = trifluoromethanesulfonic acid) imide carbonyl activation and cyclization strategy. By employing this simple method, the isoquinoline alkaloids crispine A, trolline/oleracein E, and erythrinarbine were successfully synthesized in racemic form. The reaction

  A series of novel fused isoquinolinones with isoindoloisoquinolinone, pyroloisoquinolinone, and benzoquinalizinone skeletons were synthesized from corresponding phenethylimides. The isoquinolinone derivatives were evaluated for their protective effect on chicken erythrocytes subjected to oxidative damage. The effect of isoquinolinone derivatives were analysed by estimation of cell viability, antioxidant enzyme activities, DNA damage (comet assay), PARP-1 inhibition assay and molecular docking of the compounds with PARP-1 active site. The compounds CRR-271, CRR-288 and CRR-224+225 showed significant protective effect at 100 mu M concentration. The PARP-1 inhibition assay revealed the IC50 values of CRR-271, CRR-288 and CRR-224+225 as <200 nM, further molecular docking studies shows higher binding energies with PARP-1 active site. Interesting findings in this study suggest that the novel isoquinolinone derivatives inhibit PARP-1 activity and protect cells against oxidative DNA damage, which could be implemented in the treatment of inflammatory diseases.
