Doxorubicin and 14-hydroxycarminomycin 14-O-hemiadipates and 14-O-hemipimelates (synthesized from 14-bromo derivatives of daunorubicin, carminomycin monosodium adipate, and pimelate) were converted to the corresponding N-trifluoroacetylated compounds. 13-(4-methylpiperazine-1-yl)imino derivatives of the anthracycline antibiotics were also obtained.The cytostatic activity of the compounds synthesized was studied using a panel of human and animal tumor cell lines sensitive or resistant to doxorubicin.N-Trifluoroacetylation of the antibiotics resulted in a decrease in the cytostatic activity.The activity of the water-soluble 13-(4-methylpiperazine-1-yl)imino derivatives is close to that of the corresponding parent antibiotics. - Keywords: anthracycline antibiotics; multidrug resistance

N-(Trifluoroacetyl)adriamycin 14-valerate (AD 32), a novel DNA nonbinding analogue of adriamycin with superior experimental antitumor activity, has undergone extensive clinical trial, with documentation of antitumor activity and low toxicity in human subjects.However, poor water solubility necessitates that the drug be administered to patients by continuous intravenous infusion at high dilution in a surfactant-containing formulation, with steroid prophylaxis to protect against a chest pain syndrome associated with the vehicle.On the basis of pharmacologic considerations, the title compounds have been prepared as second-generation analogues of N-(trifluoroacetyl)adriamycin 14-valerate with improved aqueous solubility; use is made of the available carboxylic acid function to solubilize the products in dilute aqueous alkaline medium.Target compounds were made by treating N-(trifluoroacetyl)-14-halodaunorubicin (bromo or iodo) with monosodium salts of dibasic acids (malonic, succinic, glutaric, adipic, pimelic, azelaic, sebacic) in aqueous acetone.All of the products showed significant in vivo antitumor activity against the murine P388 leukemia (ip tumor, ip treatment once daily on days 1, 2, 3, and 4); most compounds were superior to the +181percent increase in life span afforded by adriamycin (optimal dose 3.0 mg/kg per day), one of two drugs used as positive controls for the assays.Several of the test compounds showed highly curative activity in this system, similar to N-(trifluoroacetyl)adriamycin 14-valerate, the other positive control agent.The hemiadipate product exhibited the most desirable properties of high antitumor efficacy (86percent cure rate of all P388 tumor-bearing animals through four levels of a 40-70 mg/kg dose-response range), aqueous solubility (60 mg/mL in pH 7.4 phosphate buffer), and solution stability (no decomposition at 4 deg C, 0.5percent hydrolysis at 27 deg C, over 24 h at pH 7.4).

N-Trifluoroacetyladriamycin-14-O-hemiglutarate and -hemiadipate having antitumor activity and low toxicity are soluble in water at a physiological pH ranging from 7.2 to 7.5.
