Synthesis and Structure−Activity Relationships of Potential Anticancer Agents: Alkylcarbamates of 3-(9-Acridinylamino)-5-hydroxymethylaniline
摘要:
A series of potential 9-anilinoacridine antitumor agents, 3-(9-acridinylamino)-5-hydroxymethylaniline (AHMA) derivatives with monosubstituent at C4' and disubstituents at C4' and C5' of the acridine ring and their alkylcarbamates, were synthesized for evaluation of their antitumor activity. A structure-activity relationship (SAR) study showed that the AHMA-alkylcarbamates were more potent than their corresponding parent AHMA compounds. In addition, the cytotoxicity of the AHMA-alkylcarbamate decreased with increasing length and size of the alkyl function. Among these compounds, AHMA-ethylcarbamate (18) and 4'-methyl-5'-dimethylaminoethylcarboxamido-AHMA-ethylcarbamate (34) possess potent cytotoxicity on the inhibition of human leukemic HL-60 cell growth in culture. Further in vivo studies of these compounds displayed significant anticancer therapeutic effects in mice bearing sarcoma 180, Lewis lung carcinoma, and P388 leukemia.

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

molecular design, synthesis, and investigation of a series of acridine-triaminotriazine macrocycles that selectively bind to CTG trinucleotide repeats in DNA with minimal nonspecific binding. The limited conformational flexibility enforces the stacking of the triaminotriazine and acridine units. Isothermal titration calorimetry studies and Job plot analyses revealed that the ligands bound to d(CTG) mismatched

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.

Replacement of the 1'-methanesulfonamide group of the 9-anilinoacridine class of antitumor agents with the 1'-(dimethyl phosphoramidate) group provides compounds that are generally more lipophilic and bind more tightly to DNA. On the average, the dimethyl phosphoramidates are twice as dose potent as the corresponding methanesulfonamide (AMSA) compounds against P388 leukemia in vivo, but also show about twice the acute toxicity and no resultant improvement in tumor cell selectivity (ILSmax values) is seen. A pairwise comparison of a range of acridine-substituted compounds shows that structure-activity relationships within each series are similar and dominated by the acridine substitution pattern.
