Discovery of novel targets and mechanisms of MEK inhibitor Selumetinib for LGG treatment based on molecular docking and molecular dynamics simulation

Based on molecular docking and molecular dynamics simulation, to find a new target and mechanism of MEK inhibitor Selumetinib in the treatment of low-grade glioma (LGG), and to provide theoretical guidance for its clinical medication. All possible targets of Selumetinib were fished through the compound target prediction database. New targets of Selumetinib in the treatment of LGG were found and its mechanism was evaluated employing molecular docking, gene difference analysis, molecular dynamics simulation, and protein subcellular localization prediction. A total of 100 Selumetinib targets and 85 LGG-related targets were screened in this study. There were 7 active targets at the intersection of the two. Through protein interaction (PPI), gene enrichment analysis, and gene difference analysis, one effective target of Selumetinib was finally screened, CDK2 mainly existing in the cytoplasm, endoplasmic reticulum, and plasma membrane; the target plays a role in the treatment of LGG by inhibiting the signal pathways of PI3K Akt and participating in biological processes such as peptide amino acid modification, regulation of intracellular signal transduction, and positive regulation of cell metabolism. CDK2 may be a new direction of Selumetinib in the clinical treatment of LGG.
