antileukemic agent amsacrine with a 3'-methylamino group provides a compound (3) with a broader spectrum of action, including in vivo activityagainst experimental solidtumors. The synthesis, physicochemical properties, and biological activity of a series of acridine-substituted analogues of 3 are described. The compounds show higher levels of DNA binding, water solubility, and in vivo solidtumor activity

provided increased activityagainst the multidrug-resistant P388/ADR leukemia subline in vivo. Since activityagainst such resistant tumors is of great clinical significance, a series of acridine-substituted carbamate derivatives were evaluated against both wild-type and ADR/resistant P388 leukemia and the Lewislungsolidtumor in vivo. Structure-activity relationships for all three tumor lines were similar

In an investigation of a new class of deoxyribonucleic acid (DNA)-intercalating antitumor agents, novel acridinyl-substituted uracils have been synthesized and evaluated for activity against L1210 leukemia in vivo, and against bacteria and fungus. These compounds were prepared by the novel enamine reaction between 9-chloroacridines and 6-aminouracils. The positional effects of substituents on the acridine

Structure-activity relationships for a series of acridine-substituted 3'-N(CH3)2 derivatives of the clinical antileukemic drug amsacrine (1) are reported. The parent (unsubstituted) compound 3 has activity against the Lewis lung solid tumor that is superior to amsacrine (1), the new clinical amsacrine analogue 4, and the recently developed 3'-NHCH3 derivative 2. Although the compounds generally bind less well to DNA and are less dose potent in vivo than either their amsacrine (3'-OCH3) or 3'-NHCH3 analogues, they show very high levels of antitumor activity, with the 4-OCH3 derivative capable of effecting 100% cures of the Lewis lung solid tumor. The broad structure-activity relationships for acridine substitution more closely resemble those of the amsacrine than the 3'-NHCH3 series, with 4-substituted and 4,5-disubstituted compounds showing the highest activity.
