Objective

To study the inhibitory activity of glycycoumarin against the main RNA polymerase of the novel coronavirus and to predict the inhibitory activity of coumarin small molecules against this target enzyme.

Methods

A cell-based novel coronavirus RNA polymerase catalytic reaction system was used to test the inhibitory activity of glycycoumarin against RNA polymerase. Molecular docking technology was used to study the interaction mode of glycycoumarin and coumarin small molecules with amino acids at the active site of the main RNA polymerase of the novel coronavirus.

Results

In the RNA polymerase inhibition assay, glycycoumarin showed inhibition rates were (29.68±4.06)%, (58.30±7.65)% and (86.85±5.78)% at concentrations of 10, 25, 50 μmol/L, respectively. Glycycoumarin can enter the active site of RNA polymerase and interact with amino acids in the NTPs channel, releasing free energy of 7.6 kcal/mol during the binding process. Coumarin small molecules can bind to the active site of RNA polymerase and hinder the entry of normal substrate nucleotides.

Conclusion

Glycycoumarin has significant inhibitory activity against RNA polymerase. Coumarin small molecules can occupy the NTPs channel and inhibit the biological function of RNA polymerase. Structural modification based on the coumarin parent nucleus is a potential pathway for the development of anti-novel coronavirus drugs.

目的

研究甘草香豆素单体成分对新型冠状病毒RNA聚合酶的抑制活性,并预测香豆素类小分子对RNA聚合酶的抑制活性。

方法

应用细胞水平的新型冠状病毒RNA聚合酶催化反应体系测试甘草香豆素对RNA聚合酶的抑制活性;利用分子对接技术研究香豆素类小分子与新型冠状病毒RNA聚合酶活性位点处氨基酸的相互作用模式。

结果

在抑制RNA聚合酶的药理测试实验中,甘草香豆素在10、25、50 μmol/L浓度显示出对靶酶抑制率为(29.68±4.06)%、(58.30±7.65)%、(86.85±5.78)%。甘草香豆素可进入RNA聚合酶活性位点处并与NTPs通道氨基酸的发生分子间相互作用,结合过程释放的自由能为7.6 kcal/mol。香豆素类小分子均可结合于RNA聚合酶的活性位点处并阻碍正常底物核苷酸的进入。

结论

甘草香豆素对RNA聚合酶具有明显抑制活性,香豆素类小分子可占据NTPs通道而抑制RNA聚合酶的生物学功能,以香豆素母核结构为模板进行结构修饰是开发抗新型冠状病毒药物的一条路径。

目的

研究甘草香豆素单体成分对新型冠状病毒RNA聚合酶的抑制活性,并预测香豆素类小分子对RNA聚合酶的抑制活性。

方法

应用细胞水平的新型冠状病毒RNA聚合酶催化反应体系测试甘草香豆素对RNA聚合酶的抑制活性;利用分子对接技术研究香豆素类小分子与新型冠状病毒RNA聚合酶活性位点处氨基酸的相互作用模式。

结果

在抑制RNA聚合酶的药理测试实验中,甘草香豆素在10、25、50 μmol/L浓度显示出对靶酶抑制率为(29.68±4.06)%、(58.30±7.65)%、(86.85±5.78)%。甘草香豆素可进入RNA聚合酶活性位点处并与NTPs通道氨基酸的发生分子间相互作用,结合过程释放的自由能为7.6 kcal/mol。香豆素类小分子均可结合于RNA聚合酶的活性位点处并阻碍正常底物核苷酸的进入。

结论

甘草香豆素对RNA聚合酶具有明显抑制活性,香豆素类小分子可占据NTPs通道而抑制RNA聚合酶的生物学功能,以香豆素母核结构为模板进行结构修饰是开发抗新型冠状病毒药物的一条路径。

Objective

To study the inhibitory activity of glycycoumarin against the main RNA polymerase of the novel coronavirus and to predict the inhibitory activity of coumarin small molecules against this target enzyme.

Methods

A cell-based novel coronavirus RNA polymerase catalytic reaction system was used to test the inhibitory activity of glycycoumarin against RNA polymerase. Molecular docking technology was used to study the interaction mode of glycycoumarin and coumarin small molecules with amino acids at the active site of the main RNA polymerase of the novel coronavirus.

Results

In the RNA polymerase inhibition assay, glycycoumarin showed inhibition rates were (29.68±4.06)%, (58.30±7.65)% and (86.85±5.78)% at concentrations of 10, 25, 50 μmol/L, respectively. Glycycoumarin can enter the active site of RNA polymerase and interact with amino acids in the NTPs channel, releasing free energy of 7.6 kcal/mol during the binding process. Coumarin small molecules can bind to the active site of RNA polymerase and hinder the entry of normal substrate nucleotides.

Conclusion

Glycycoumarin has significant inhibitory activity against RNA polymerase. Coumarin small molecules can occupy the NTPs channel and inhibit the biological function of RNA polymerase. Structural modification based on the coumarin parent nucleus is a potential pathway for the development of anti-novel coronavirus drugs.
