Existing antidiabetic drugs, including α-glucosidase and α-amylase inhibitors, often exhibit side effects and limited efficacy, prompting the search for safer alternatives. Hydrazone derivatives have shown promising antidiabetic activity due to their structural diversity and enzyme-targeting potential. In this study, 10 novel hydrazone compounds were synthesized and evaluated for their inhibitory effects against α-amylase and α-glucosidase. Compounds 8 and 10 showed the highest dual inhibition: compound 8 with IC 50 = 30.21 ± 0.16 μM (α-amylase) and 38.06 ± 0.80 μM (α-glucosidase); compound 10 with IC 50 = 34.49 ± 0.37 and 40.44 ± 0.23 μM, respectively. Cytotoxicity on HEK293 cells via MTT assay revealed IC 50 values of 61.04 μM (compound 7 ) and 69.25 μM (compound 9 ), while other compounds and acarbose were nontoxic up to 100 μM. In silico drug-likeness analysis showed that 80% of the compounds complied with Lipinski’s rules, with topological polar surface area (TPSA) values ranging between 63 and 112 Å 2 . Gastrointestinal absorption was high for 7 out of 10 compounds; none showed blood–brain barrier permeability. Molecular docking confirmed strong binding interactions of compounds 8 and 10 with both enzymes’ active sites. These findings highlight hydrazone scaffolds as potent and safe candidates for further antidiabetic drug development.
