A series of chromone-thiazolidine-2,4-dione derivatives were synthesized and tested for their a-glucosidase inhibitory activity. Compound e28 showed the strongest inhibitory activity, which was reversible and non-competitive. Further studies revealed that e28 had good safety.
A series of chromone-thiazolidine-2,4-dione derivatives (e1 -28) were synthesized and screened for their a-glucosidase inhibitory. All synthetic derivatives presented excellent a-glucosidase inhibitory with IC50 values ranging from 2.40 +/- 0.11 to 5.66 +/- 0.15 lM, comparing to positive control acarbose (IC50 value: 640.57 +/- 5.13 lM). Among them, compound e28 dis-played the strongest a-glucosidase inhibitory (IC50 value: 2.40 +/- 0.11),-267 times stronger than positive control acarbose. Kinetic studies revealed that compound e28 was a reversible non-competitive inhibitor. CD spectra and 3D fluorescence spectra results explained that compound e28 changed the conformational changes of a-glucosidase. Molecular docking simulated the binding between compound e28 and a-glucosidase. In vitro cytotoxicity assay ascertained the good security of e28.(c) 2023 The Author(s).
