Doxorubicin was isolated from a mutated variant of S. peucetius (var. caesius). It differs from daunorubicin only by the addition of a hydroxyl group at the carbon 14 position. This modification greatly changes the activity of the drug making it highly effective against a wide range of solid tumours, leukaemia and lymphomas.
Doxorubicin showed better activity than daunorubicin against mouse tumors, and especially solid tumors. It also showed a higher therapeutic index, yet the cardiotoxicity remained. [50] Doxorubicin and daunorubicin together can be thought of as prototype compounds for the anthracyclines. Subsequent research has led to many other anthracycline ...
Daunorubicin, also known as daunomycin, is a chemotherapy medication used to treat cancer. [2] Specifically it is used for acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), chronic myelogenous leukemia (CML), and Kaposi's sarcoma . [ 2 ]
1.10 Platinum compounds: Carboplatin: IV: Reacts with DNA, inducing apoptosis, non-cell cycle specific. Ovarian cancer, lung cancer and squamous cell head and neck cancer: Myelosuppression, nausea and vomiting (30-90%), peripheral neuropathy, ototoxicity, anaphylaxis, acute kidney failure (rare), haemolytic uraemic syndrome (rare) and loss of ...
Topoisomerase inhibitor classes have been derived from a wide variety of disparate sources, with some being natural products first extracted from plants (camptothecin, [10] etoposide [13]) or bacterial samples (doxorubicin, [14] indolocarbazole [15]), while others possess purely synthetic, and often accidental, origins (quinolone, [11 ...

[10] The United States Food and Drug Administration has also approved a dexrazoxane for use as a treatment of extravasation resulting from IV anthracycline chemotherapy . [ 11 ] [ 12 ] Extravasation is an adverse event in which chemotherapies containing anthracylines leak out of the blood vessel and necrotize the surrounding tissue.
The study involved 10 animals, five in the experimental group that engaged in regular physical activity and five in the control group that did not engage in physical exercise.
