Drug-drug interation prediction between ketoconazole and anti-liver cancer drug Gomisin G|
Liu, Xiaoyang; Ni, Chenming; Li, Chengqing & Liu, Tao
Background: Gomisin G, isolated from herb Schisandra chinensis, exhibits anti-tumor activities. Therefore, Gomisin G is a drug candidate for anti-liver cancer therapy.
Aims: To predict the metabolic behavior and metabolism-based drug-drug interaction of gomisin G.
Methods: Molecular docking method was used. The crystal structure of CYP3A4 with the ligand ketoconazole was chosen
from protein data bank (http://www.rcsb.org/pdb). Chemdraw software was used to draw the two-dimensional structure of
gomisin G with standard bond lengths and angles.
Results: Gomisin G can be well docked into the activity site of CYP3A4, and distance between gomisin G the heme active
site was 2.75 Å. To evaluate whether the inhibitors of CYP3A4 can affect the metabolism of gomisin G, co-docking of
gomisin G and ketoconazole was further performed. The distance between ketoconazole and activity center (2.10 Å) is closer
than the distance between gomisin G and activity center of CYP3A4, indicating the easy influence of CYP3A4’s strong
inhibitor towards the metabolism of gomisin G.
Conclusion: Gomisin G is a good substrate of CYP3A4, and CYP3A4 inhibitors easily affect the metabolism of Gomisin
