Doxorubicin, sold under the brand name Adriamycin among others, is a chemotherapy medication used to treat cancer. [10] This includes breast cancer, bladder cancer, Kaposi's sarcoma, lymphoma, and acute lymphocytic leukemia. [10] It is often used together with other chemotherapy agents. [10] Doxorubicin is given by injection into a vein. [10]
As an example, the incidence of congestive heart failure is 4.7%, 26% and 48% respectively when patients received doxorubicin at 400 mg/m 2, 550 mg/m 2 and 700 mg/m 2. [4] Therefore, the lifetime cumulative doxorubicin exposure is limited to 400–450 mg/m 2 in order to reduce congestive heart failure incidence to less than 5%, although ...
Daunorubicin: IV: Inhibits DNA and RNA synthesis by intercalating DNA base pairs. Inhibits DNA repair by inhibiting topoisomerase II. Acute leukaemias: Myelosuppression, cardiotoxicity, anaphylaxis (rare), secondary malignancies (particularly acute myeloid leukaemia and myelodysplastic syndrome) and radiation recall. Doxorubicin: IV: As above.
Daunorubicin is in the anthracycline family of medication. [3] It works in part by blocking the function of topoisomerase II. [2] Daunorubicin was approved for medical use in the United States in 1979. [2] It is on the World Health Organization's List of Essential Medicines. [4] It was originally isolated from bacteria of the Streptomyces type. [5]
Epirubicin is a 4'-epi-isomer of doxorubicin and a derivative of daunorubicin. As an anthracycline antibiotic it belongs to several chemical classes such as: aminoglycosides, tetracene quinones, p-quinones, primary alpha-hydroxy ketone and tertiary alpha-hydroxy ketones. Due to numerous ionisable groups, it has multiple pka (pKa1 = 9.17 (phenol ...
Cardiotoxicity (heart damage) is especially prominent with the use of anthracycline drugs (doxorubicin, epirubicin, idarubicin, and liposomal doxorubicin). The cause of this is most likely due to the production of free radicals in the cell and subsequent DNA damage .
[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.
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 ...
