Background:: Deficiency of insulin signaling in type 2 diabetes results from insulin resistance or defective insulin secretion and induced hyperglycemia. By reducing glycated hemoglobin, SGLT2 inhibitors improve hyperuricemia, blood lipids, and weight loss without increasing the risk of hypoglycemia. By targeting this pathway, SGLT2 inhibitors can become a prominent target in the management of type 2 diabetes. Objective:: This study aimed to carry out the molecular docking and ADMET prediction of novel imidazo(2,1-b)-1,3,4 thiadiazole derivatives as SGLT2 inhibitors. Methods:: The chemical structures of 108 molecules were drawn by using ChemDraw Professional 15.0. Further, their energy minimization was also carried out by using Chem Bio Draw three-dimensional (3D) Ultra 12.0. Molecular docking was also carried out using a Molegro Virtual Docker to identify the best-fitting molecules and to identify the potential leads on the basis of dock score. The predicted parameters of drug-likeness according to Lipinski’s rule of five, such as molecular weight, log P, hydrogen bond acceptor, hydrogen bond donors, and number of rotatable bonds of the selected compounds, were predicted using pKCSM software. Results:: About 108 molecules were designed by employing different substitutions on imidazothiadiazole nucleus as SGLT2 inhibitors. Out of these, 10 compounds were found to have better interactions with the active site of SGLT2 protein and the highest dock scores compared to canagliflozin. Compounds 39a and 39b demonstrated good interactions and the highest docking scores of -155.428 and -142.786, respectively. The in silico physicochemical properties of the best compounds were also determined. Additionally, these compounds suggested a good pharmacokinetic profile as per Lipinski's rule of five (orally active drugs). Conclusion:: Novel imidazo (2,1-b)-1,3,4 thiadiazole derivatives were strategically designed, and their binding affinity was meticulously evaluated against the SGLT2 protein. This endeavor yielded pioneering lead compounds characterized by ultimate binding affinity, coupled with optimal ADMET properties in adherence to Lipinski's rule of five and favourable noncarcinogenic profile.
