利用药物拼合原理合成了30个含不同取代基的四氢-β-咔啉并二酮哌嗪类衍生物. 采用噻唑蓝(MTT)法测试了目标化合物对三种肿瘤细胞株(LLC、A-549、NCI-H1666)增殖的抑制活性. 结果显示, 大多数化合物对这三种肿瘤细胞株表现出中等至良好的抑制活性, 且多数化合物的IC50值低于20 μmmol/L. 其中, 所得目标化合物对A549细胞系表现出良好的抑制活性, 特别是(S)-2,7-双(4-氟苄基)-1,2,3,6,7,12-六氢吡嗪-4H-并[1,2-a]四氢-β-咔啉-1,4-二酮(6o)和(S)-7-(4-氟苄基)-2-己基-1,2,3,6,7,12-六氢-4H-吡嗪并[1,2-a]四氢-β-咔啉-1,4-二酮(6y)对A549细胞表现出优异的抑制活性, 且IC50值均低于10 μmmol/L. 整体来说, 化合物6o、(S)-2-(4-氟苄基)-7-(4-三氟甲基苄基)-1,2,3,6,7,12-六氢- 4H-吡嗪并[1,2-a]四氢-β-咔啉-1,4-二酮(6p)、化合物6y和(S)-2-己基-7-(4-三氟甲基苄基)-1,2,3,6,7,12-六氢-4H-吡嗪并[1,2-a]四氢-β-咔啉-1,4-二酮(6z)对LLC、A549和NCI-H1666细胞系表现出良好的抑制活性, 且IC50值均低于20 μmmol/L, 具有潜在的抗肿瘤研究价值. 分子对接结果表明, 化合物6o6p与血管内皮生长因子受体2 (VEGFR-2) (PDB:4AGD)的多个氨基酸残基之间存在良好的相互作用. 同时, 分子动力学模拟结果表明, 化合物6p与4AGD之间能保持二者的结合稳定性和构象一致性.

A series of 30 tetrahydro-β-carboline fused diketopiperazine derivatives containing different substituents were synthesized using the principle of drug combination. Their antiproliferative activities were evaluated against three tumor cell lines (LLC, A-549, NCI-H1666) via methyl thiazolyl tetrazolium (MTT) assay. The results showed that most compounds exhibited moderate to good inhibitory activity against these three tumor cell lines, and the IC50 values of most compounds were below 20 μmol/L. Among them, the target compounds showed good inhibitory activity against A549 cell line, especially (S)-2,7-bis(4-fluorobenzyl)-1,2,3,6,7,12-hexahydropyrazine-4)-perhydro-β-carboline-1,4-dione (6o) and (S)-7-(4-fluorobenzyl)- 2-hexyl-1,2,3,6,7,12-hexahydro-4H-pyrazino[1,2-a]tetrahydro-β-carboline-1,4-dione (6y) showed excellent inhibitory activity against A549 cell line, with IC50 values below 10 μmol/L. Overall, compound 6o, (S)-2-(4-fluorobenzyl)-7-(4-trifluoromethyl- benzyl)-1,2,3,6,7,12-hexahydro-4H-pyrazino[1,2-a]tetrahydro-β-carboline-1,4-dione (6p), 6y, and (S)-2-hexyl-7-(4-trifluoro- methylbenzyl)-1,2,3,6,7,12-hexahydro- 4H-pyrazino[1,2-a]tetrahydro-β-carboline-1,4-dione (6z) exhibit good inhibitory activity against LLC, A549, and NCI-H1666 cell lines, with IC50 values all below 20 μmol/L, indicating potential anti-tumor research value. The molecular docking results indicate that compounds 6o and 6p have good interactions with multiple amino acid residues of VEGFR-2 (PDB:4AGD). Meanwhile, the molecular dynamics simulation results indicate that the binding stability and conformational consistency between compound 6p and 4AGD can be maintained.
