| 摘要: |
| 目的 基于分子对接探讨水杨酰苯胺化合物Ⅰ-Ⅳ与代谢型谷氨酸受体5（metabotropic glutamate receptor 5，mglu5）之间的相互作用并测定化合物Ⅰ-Ⅳ的体外抗肝癌HepG2细胞增殖活性。方法 采用计算机软件，以mglu5结晶复合物5CGD为受体模板，将水杨酰苯胺化合物Ⅰ-Ⅳ进行分子对接研究；利用MTT法测定水杨酰苯胺化合物Ⅰ-Ⅳ对肝癌HepG2细胞的增殖抑制活性。结果 水杨酰苯胺化合物Ⅰ-Ⅳ与mglu5的活性口袋产生疏水作用以及与活性口袋关键氨基酸残基SER809产生氢键结合；水杨酰苯胺化合物Ⅰ-Ⅳ对肝癌细胞HepG2的抗增殖活性IC50值分别为2.55 μmol/L、3.99 μmol/L、3.12 μmol/L和7.55 μmol/L。结论 水杨酰苯胺化合物Ⅰ-Ⅳ与mglu5对接的结合信息有助于水杨酰苯胺类mglu5拮抗剂的结构优化和新型mglu5拮抗剂设计，该类化合物的抗肿瘤作用值得进一步研究。 |

| Abstract: |
| Objective To study the interaction between the salicylanilides I-IV with metabotropic glutamate receptor 5 (mglu5) based on molecular docking and their antitumor activity in vitro. Methods The molecular docking study of salicylanilides I-IV were performed by using mglu5 as a receptor template by in silica software. In vitro cytotoxicity of salicylanilides I-IV to human hepatocellular carcinoma cell line HepG2 was measured by a MTT method. Results It was found that salicylanilides I-IV interacted with mglu5 binding site by hydrophobic interaction and a key hydrogen bond with amino acid residue SER809. These interactions were closely related to biological activity. Compounds I-IV showed inhibitory effect on the proliferation of HepG2 cells with the IC50 values of 2.55 μM, 3.99 μmol/L, 3.12 μmol/L and 7.55 μmol/L, respectively. Conclusion The binding information of salicylanilides with mglu5 would be useful for modifying the structure and designing novel mglu5 antagonists. The antitumor activity of compounds of this type would be further studied. |
