Fig. 6From: Pseudoginsengenin DQ exerts antitumour activity against hypopharyngeal cancer cells by targeting the HIF-1α-GLUT1 pathwayMolecular docking of ginsenoside PDQ and HIF-1α. a The chemical structure of 24 (S)-PDQ. b Molecular docking of PDQ in the active site of HIF-1α. The C-25 hydroxyl group in PDQ structure forms a hydrogen bond with His378 residue of HIF-1α (PDB ID: 4H6J). The docking score is − 7.3Back to article page
