The E,Z-isomers of 3-arylidene substituted flavanone, chromanone and 3-aryl substituted flavone derivatives were tested in vitro for their cytotoxic activity against three cancer cell lines (HL-60, NALM-6, WM-115) and normal cell line (HUVEC). It was observed that substitution at C3 position led to significant enhance in cytotoxicity. Isomeric configuration of 3-arylideneflavanones had an influence on the cytotoxic potential. Multiple regression analysis combined with variable selection by genetic algorithm was used to model relationships between molecular descriptors and the cytotoxic activity. The most accurate QSAR models were based on a combination between energy of LUMO, experimental value of log P and partial charge on carbonyl oxygen (δO2).

Choline hydroxide was used as a basic catalyst for aldol condensation reactions to produce new C-C bonds between several ketones and aldehydes. Choline supported on MgO exhibits higher TOF values than other well known basic catalysts in these reactions.

E-3 Arylideneflavanones 4 on UV irradiation using quartzware undergo auto-oxidation to 3-aroylflavones 5.Photolysis using pyrex filter in the presence of iodoform furnishes 3-α-hydroxybenzylflavones indicating the intermediacy of the hydroperoxide 11 and form a new general method for the synthesis of these compounds not available by other routes.
