Amino-Substituted 2-[2-(Dimethylamino)ethyl]-1,2-dihydro-3H-dibenz[de,h]isoquinoline-1,3-diones. Synthesis, Antitumor Activity, and Quantitative Structure-Activity Relationship
摘要:
Sets of 2-[2'-(dimethylamino)ethyl]-1,2-dihydro-3H-dibenz[de,h]isoquinoline-1,3-diones with amino and actylamino groups at each of the eight positions on the anthracene nucleus were synthesized from appropriately substituted anthracenes. Their evaluation in in vitro antitumor and cardiotoxicity assays revealed a very strong dependence of potency on the position of substitution. Certain compounds, including the 4-, 5-, 7-, and 9-amino derivatives, showed significantly higher potency than the unsubstituted parent compound, azonafide. Among them, 7-aminoazonafide had low cardiotoxicity relative to cytotoxicity. In general, the acetylamino analogues were less potent than the amino derivatives against tumor cells and neonatal rat heart myocytes; however, 5-(acetylamino)azonafide was highly cardiotoxic. 9-Aminoazonafide was more efficacious than azonafide or amonafide against P388 leukemia in mice. Statistically significant correlations were made between the ability of amino analogues to increase the transition melt temperature (Delta T-m) of DNA and their potency against solid tumors, leukemia cells, or cardiac myocytes.
COMPOSITIONS AND METHODS TO IMPROVE THE THERAPEUTIC BENEFIT OF SUBOPTIMALLY ADMINISTERED CHEMICAL COMPOUNDS INCLUDING SUBSTITUTED NAPHTHALIMIDES SUCH AS AMONAFIDE FOR THE TREATMENT OF IMMUNOLOGICAL, METABOLIC, INFECTIOUS, AND BENIGN OR NEOPLASTIC HYPERPROLIFERATIVE DISEASE CONDITIONS

The present invention describes methods and compositions for improving the therapeutic efficacy of therapeutic agents previously limited by suboptimal therapeutic performance by either improving efficacy as monotherapy or reducing side effects. Such methods and compositions are particularly applicable to naphthalimides such as amonafide or analogs, derivatives, or prodrugs thereof.

New 2-[2'-(dimethylamino)ethyl]-1,2-dihydro-3H-dibenz[de,h]isoquinoline-1,3- diones with substituents at the 4, 8, 9, 10, and 11 positions were synthesized. Diazonium salts prepared from aminoazonafides were key intermediates for many of the analogues. Six of the new compounds were more potent than azonafide in a panel of tumor cells including human melanoma and ovarian carcinoma and murine L1210 leukemias
