Synthesis, anti-ferroptosis, anti-quorum sensing, antibacterial and DNA interaction studies of chromene-hydrazone derivatives.

Nineteen chromene-hydrazone derivatives containing a variety of structural modifications on the hydrazone moiety were synthesized. Structure-activity correlations were investigated to determine the influence of structural variations on anti-ferroptosis, anti-quorum sensing, antibacterial, DNA cleavage and DNA binding properties. Ferroptosis inhibitory activity was determined by measuring the ability of the derivatives to reverse erastin-induced ferroptosis.
