Molecular Docking Evaluation 2.6. Molecular Docking Analysis HIF1 plays an important part within the survival, growth and metastasis of tumor cells, suggesting HIF1 plays a crucial part in the survival, development and metastasis of tumor cells, suggesting that HIF1 inhibitors possess effective impact for tumor remedy. Consequently, we investigated the that HIF1 inhibitors possess effective effect for tumor remedy. Consequently, we investigated the potential of AATP against HIF1 and binding affinity employing molecular docking approach. As depicted possible of AATP against HIF1 and binding affinity employing molecular docking method. As inside the Figure six, AATP combined amino acid residues GLY180, GLN181, HIS199, APS201, GLU202 and depicted in the Figure six, AATP combined amino acid residues GLY180, GLN181, HIS199, APS201, GLN203 of HIF1, as well as the sturdy interaction was supported by the formation of a hydrogen bond, GLU202 and GLN203 of HIF1, plus the sturdy interaction was supported by the formation of a and its docking score was 100.21 kcal/mol. The higher binding energies between AATP and HIF1 hydrogen bond, and its docking score was 100.21 kcal/mol. The higher binding energies amongst AATP and HIF1 contribute to suppression of activity of HIF1, resulting in downregulation of downstream reactions that relate to tumor metastasis and VM formation.Mar.
