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

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.

The preparation and antitumor activity of a series of 3'-alkylamino and 3'-dialkylamino analogues of amsacrine are reported. The results support previous work suggesting that the presence of electron-donating groups in the 3'-position of the anilino ring substantially enhance the antitumor activity of amsacrine analogues, possibly by the provision of high levels of electron density at the 6'-position. The alkylamino derivatives generally possess tighter DNA binding, higher levels of in vitro and in vivo antileukemic activity, and greater aqueous solubility than the corresponding amsacrine analogues.

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
