AbstractAcetylcholinesterase (AChE) is a primary target for Alzheimer’s therapy while recently sodium glucose cotransporter 2 (SGLT2) has gained importance as a potential target for Type 2 Diabetes Mellitus (T2DM) therapy. The present study emphasizes the molecular interactions between a new Food and Drug Administration (FDA) approved antidiabetic drug ‘Invokana’ (chemically known as Canagliflozin) with AChE and SGLT2 to establish a link between the treatment of T2DM and Alzheimer’s Disease (AD). Docking study was performed using ‘Autodock4.2’. Both hydrophobic and π-π interactions play an important role in the correct positioning of Canagliflozin within SGLT2 and catalytic site (CAS) of AChE to permit docking. Free energy of binding (ΔG) for ‘Canagliflozin-SGLT2’ interaction and ‘Canagliflozin - CAS domain of AChE’ interaction were found to be -10.03 kcal/mol and -9.40 kcal/mol, respectively. During ‘Canagliflozin-SGLT2’ interaction, Canagliflozin was found to interact with the most important amino acid residue Q457 of SGLT2. This residue is known for its interaction with glucose during reabsorption in kidney. However, ‘Canagliflozin-CAS domain of AChE’ interaction revealed that out of the three amino acids constituting the catalytic triad (S203, H447 and E334), two amino acid residues (S203 and H447) interact with Canagliflozin. Hence, Invokana (Canagliflozin) might act as a potent dual inhibitor of AChE and SGLT2. However, scope still remains in the determination of the three-dimensional structure of SGLT2-Canagliflozin and AChE-Canagliflozin complexes by X-ray crystallography to validate the described data. Since the development of diabetes is associated with AD, the design of new AChE inhibitors based on antidiabetic drug scaffolds would be particularly beneficial. Moreover, the present computational study reveals that Invokana (Canagliflozin) is expected to form the basis of a future dual therapy against diabetes associated neurological disorders.
