Abstract: A set of 2,4-diamino-5-(3-X-phenyl)-s-triazines was used to inhibit the growth of tumor cells (L5178 leukemia) in culture. The molar concentration (C) of triazine causing 50% reduction in the rate of cell growth was used to develop a quantitative structure-activity relationship: log 1/C = 1.32 pi - 1.70 log (beta.10 pi + 1) + 0.44I + 8.10, where pi is the hydrophobic constant for X, beta is a disposable parameter, and I is an indicator variable for congeners containing a -CH2Z-C6H4-Y moiety (Z = O or NH). This equation is compared with similar equations derived for the inhibition of dihydrofolate reductase from leukemia cells and bovine liver.
