Microtubule affinity regulating kinase 4 (MARK4) regulates the mechanism of microtubules by its ability to phosphorylate microtubule-associated proteins (MAP's). MARK4 is known for major role in tau phosphorylation via phosphorylating Ser262 residue KXGS motif, which results detachment from microtubule. In lieu this vital pathology, a hallmark Alzheimer's disease (AD), druggable target treat AD and other neurodegenerative disorders (NDs). There growing evidence that NDs diabetes are connected with many pieces literature demonstrating high risk developing diabetic patients. Metformin (Mtf) has been drug use against type 2 mellitus (T2DM) long time; however, recent studies have established therapeutic effect diseases (NDs), namely AD, Parkinson's (PD) amnestic mild cognitive impairment. study, we explored inhibitory potential Mtf, employing silico vitro approaches. Molecular docking demonstrated Mtf binds significant -6.9 kcal/mol forming interactions binding pocket's critical residues.
