Abstract/Summary

Oxidative stress is associated with the pathology of neurodegenerative diseases. Identification of small molecules capable of protecting against oxidative stress is therefore of significant importance. In this context, a library of 76 hydroxy flavones, methoxy flavones and their 4-thio analogues has been evaluated for neuroprotection against H2O2-induced oxidative stress. This revealed the synthetic 7,8-dihydroxy 4-thioflavones as neuroprotective compounds, with 14d and 18d showing highest neuroprotective effects at lower concentrations (0.3 μM). Neuroprotection was found to be mediated via activation of the anti-apoptotic cell survival proteins of the ERK1/2 and PI3K/Akt pathways. Structure-activity relationship analysis revealed the B-ring phenyl group as essential for greater neuroprotection. Replacing the 4-C=O moiety with a 4-C=S moiety also generally enhanced neuroprotection.
