| 中文摘要: |
| 目的 以氧化的Aaptamine衍生物Demethyloxyaaptamine为底物,合成了12个氨基酸酯偶联的衍生物进行抗肿瘤活性研究。 方法 通过化学合成手段,合成了12个氨基酸偶联的衍生物,采用CCK-8法对衍生物的抗肿瘤活性进行测定。结果 6个氨基酸酯修饰的衍生物对Raji细胞的活性均强于天然产物2和4,半抑制浓度(IC50)范围为(1.0 ± 0.3)~(1.5 ± 0.4) μmol/L。其中,化合物A1和B7都表现出了对Raji细胞更强的选择性,选择性指数分别为SI(A1)(IC50SKOV3/HepG2 / IC50RaJi) > 13、SI(B7)(IC50SKOV3/HepG2 / IC50RaJi) > 14。 |
| English Summary: |
| Objective Using the oxidized derivative Demethyloxyaaptamine as a substrate, 12 amino acid ester-coupled derivatives were synthesized and tested for their anti-tumor activity. Methods Through chemical synthesis, 12 amino acid-coupled derivatives were synthesized, and their anti-tumor activity was evaluated using the CCK-8 method. Results Six amino acid ester-modified derivatives exhibited stronger activity against Raji cells compared to the natural product 2 and 4, with IC50 value ranging from (1.0 ± 0.3) to (1.5 ± 0.4) μmol/L. Among them, Compound A1 and B7 possessed stronger selectivity against Raji cells, with selectivity index SI(A1)(IC50SKOV3/HepG2 / IC50RaJi) > 13和SI(B7)(IC50SKOV3/HepG2 / IC50RaJi) > 14. |
