ABSTRACT
Currently, SGLT2 inhibitors have established themselves as an efficacious class of agents to treat type-2 diabetes mellitus with main action of increasing glucose excretion through urine. This report describes the design, synthesis & assessment of innovative C-aryl glycoside-based SGLT2 inhibitors with an enhanced binding affinity and dual inhibition potential. For rational drug design, enhanced H-bonding, π-π stacking, and hydrophobic interactions were derived from critical key heterocyclic phenols and alcohols so as to rope in SGLT2 inhibitors against C-aryl glycosides-based SGLT2 inhibitors. As per molecular docking analysis, QPB-1 was found to be having the best affinity (Vina score: -10.7) compared with dapagliflozin (-10.0) and empagliflozin (-8.7) against a panel of key residues in Pocket C2 (ASP21, ASP25, ILE26, PHE33, and TRP172). On the other side, biological assessment with α-amylase inhibition assays showed that QPB-1 (85% inhibition, IC₅₀ = 25 µM) was comparable to acarbose (85%, IC₅₀ = 24 µM) and superior to dapagliflozin (78%, IC₅₀ = 32 µM) and empagliflozin (74%, IC₅₀ = 40 µM). Other promising derivatives, QPB-9 (80%, IC₅₀ = 30 µM) and QPB-6 (77%, IC₅₀ = 35 µM), also exhibited strong inhibitory activity. This indicates that our novel C-aryl glycoside-based inhibitors have enhanced stability, stronger inhibition, and dual glucose-lowering mechanisms, qualifying them as promising candidates for next-generation antidiabetic therapy. Further studies, including preclinical evaluation and pharmacokinetic profiling, are being planned to test the therapeutic prospect of these agents.
