In vitro cytotoxic activity of novel protoflavone analogs – selectivity towards a multidrug resistant cancer cell line.
BACKGROUND:
Protoapigenone (PA), a natural flavonoid possessing an unusual p-quinol moiety on its B ring, is a prospective novel lead compound against cancer currently in development, together with WYC0209, a potent synthetic PA analog. Structure activity relationships (SAR) concerning different 1′-O-alkyl side-chains were also studied on two sets of derivatives.
