Some new 2,6-disubstituted pyrano- and 1,2-dihydropyrano[2,3-c]xanthen-7-ones have been synthesized and their antiproliferative activity has been evaluated against MDA-MB-231 breast cancer cells. The antiproliferative activity evaluation of the compounds provided evidence that a dimethylamino substituted side chain and the presence of 1,2 double bond play a key role in cell growth inhibition. Among the tested derivatives the 6-dimethylaminoethylamino-2-nitropyranoxanthenone analogue possessed a significant inhibitory effect in a wide range of concentrations. (c) 2006 Elsevier Masson SAS.
