The cytotoxic effects and alkylating activity of a series of 3-[1-(alkylamino)-ethylidene]-chroman-2,4-dione (4a-4c), 2-methoxy-3[1-(alkylamino)-ethylidene]-2,3-dihydro-2,4-dioxo-2.5 -benzo[e][1,2] oxaphosphinane (5a-5c) and [2-oxo-4-phenyl(alkyl)-2H-chromen-3-yl]-phosphonic acids dimethyl ester (6a-6c) on the two leukemia cell lines HL-60 and NALM-6 have been determined. The test compounds are much more toxic to NALM-6 cells than to HL-60 cells. IC50 data are up to nine times lower for the NALM-6 than for the HL-60 cell lines. As determined in an in vitro Preussmann test phosphonic derivatives 6a-6c possess very high (.) alkylating activity, phosphoric derivatives 5a-5c are less active (+ +) while the derivatives 4a-4c can be included in the group of low activity (+) alkylating agents. Using regression analysis QSAR we found a relationship between biological activity and the physicochemical properties of the test compounds. Their cytotoxic effect increases with an increase of the hydrophobic parameters in the region of the substituents at the 2-, 3- and 4-positions of the benzopyrone skeleton of 4-6.
