title: Synthesis, physicochemical properties and biological activity of 2,6-disubstituted 7-methylpurines and the 7,9-dialkyl analogues.
abstract: The preparation of several derivatives of 2,6-disubstituted-7-methylpurines and the 7,9-dialkyl analogues possessing a potential cytotoxic or cytostatic activity has been described. These compounds were tested for biological activity using a method for the determination of the toxic effects of chemical compounds on the growth of green alga Chlorella vulgaris, Beijerinck 1890. The effective concentration (EC50) was calculated.
