      The quinazoline-2,4-diones scaffold is found in bioactive compounds, commercial drugs and exhibit important biological activities. However, their antidiabetic activity is rarely explored. For this purpose, an easy one-pot three-components and straightforward synthesis of 3-substituted quinazoline-2,4-diones was designed, in both, the catalyst- and solvent-free conditions under microwave irradiation. Additionally, the synthesized compounds were screened for in vitro a-amylase and a-glucosidase inhibitory activity, as well as antioxidants and cytotoxicity. The quinazoline-2,4-diones were isolated, with yields in the range of 30-65%.The compounds 3d, 3e, 3g and 3h displayed moderate activity against a-amylase and/or a-glucosidase enzymes compared with the acarbose drug. The molecular docking study revealed that all active compounds displayed a different type of intermolecular interaction in the pocked site of these enzymes. Interestingly, inthe Artemia salina assay, the compound 3d exhibited a higher cytotoxic effect than 5-fluorouracil. All these results support the pharmacological potential of quinazoline-2,4-diones since all evaluated compounds behave as moderate inhibitors of the enzymes a-amylase and/or a-glucosidase.
