The anthracenedione antineoplastic agents mitoxantrone and ametantrone are potent inhibitors of basal and drug-stimulated lipid peroxidation in a variety of subcellular systems (Kharasch, E. D., and Novak, R. F. (1983) J. Pharmacol. Exp. Ther. 226, 500-506). The mechanism by which these compounds function as antioxidants has been investigated using enzymic and chemical systems. Mitoxantrone and...

objective(s):multidrug resistance (mdr) of cancer cells is a major obstacle to successful chemotherapy. overexpression of breast cancer resistance protein (bcrp) is one of the major causes of mdr. in addition, it has been shown that pi3k/akt signaling pathway involves in drug resistance. therefore, we evaluated the effects of novel approaches including sirna directed against bcrp and targeted t...

Corticosteroid: Corticosteroids did not prove to impair the immune response following influenza vaccination.10 Interferon-beta (INF-β): Seasonal influenza vaccination is safe and effective in 90.9% and 93.0% INF-treated patients.11 Glatiramer acetate (GA): GA may present a lower protection after influenza vaccination compared to healthy individuals.12 Mitoxantrone: Mitoxantrone can impair influ...

I n Western countries, prostate cancer is the most common malignancy in men and ranks third in mortality. In 2010, an estimated 217 730 new cases are anticipated in the United States, and about 32 050 men are expected to die from the disease. Until 2004, numerous clinical trials in men with metastatic castration-resistant prostate cancer (mCRPC) failed to demonstrate any significant change in o...

PURPOSE Flavopiridol is a cyclin-dependent kinase inhibitor that is cytotoxic to leukemic blasts. In a phase I study of flavopiridol followed by 1-beta-d-arabinofuranosylcytosine (ara-C) and mitoxantrone, overall response rate for adults with relapsed and refractory acute myelogenous leukemias (AML) was 31%. We have now completed a phase II study of sequential flavopiridol, ara-C, and mitoxantr...

A mitoxantrone-resistant human MCF-7 breast cancer subline (MCF/MX) which is approximately 4000-fold resistant to mitoxantrone was isolated by serial passage of the parental wild-type MCF-7 cells (MCF/WT) in stepwise increasing concentrations of drug. MCF/MX cells were also approximately 10-fold cross-resistant to doxorubicin and etoposide but were not cross-resistant to vinblastine. Intracellu...

BACKGROUND Doxorubicin plus ketoconazole has exhibited significant activity in patients with advanced prostate cancer. However, overall and cardiac-specific toxicity was reported to be high. Mitoxantrone has activity similar to that of doxorubicin, is less cardiotoxic, and is widely used to treat prostate cancer. The current study sought to evaluate the toxicity and activity of mitoxantrone plu...
