BACKGROUND Fifteen chalcones were subjected to quantitative structure-activity relationship (QSAR) analysis based on their cytotoxicity and tumor specificity, in order to find their new biological activities. MATERIALS AND METHODS Cytotoxicity against four human oral squamous cell carcinoma cell lines and three oral mesenchymal cells was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diph...
An efficient cyclization of 2’-hydroxychalcone to flavanone using calcium chloride as a catalyst was developed. The scope of the reaction was studied with substituted 2’-hydroxychalcone and these chalcones was converted into corresponding flavanone in good yield. The merits of this method are inexpensive and easily available catalyst, easy workup procedure, avoid use of toxic solvent.
