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 was adopted as the international name. [5] Initially it was seen to have activity against murine tumours and then in clinical trials it was found to be active against leukaemia and lymphomas. Doxorubicin was isolated from a mutated variant of S. peucetius (var. caesius). It differs from daunorubicin only by the addition of a ...
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 ]
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 ...
In contrast, only one known non-wild type species, Streptomyces peucetius subspecies caesius ATCC 27952, was initially found to be capable of producing the more widely used doxorubicin. [1] This strain was created by Arcamone et al. in 1969 by mutating a strain producing daunorubicin, but not DXR, at least in detectable quantities. [2]
Doxorubicin intercalating DNA. Streptomyces, yielded the medicines doxorubicin (Doxil), daunorubicin (DaunoXome), and streptozotocin (Zanosar). Doxorubicin is the precursor to valrubicin (Valstar), myocet, and pirarubicin. Daunorubicin is the precursor to idarubicin (Idamycin), epirubicin (Ellence), and zorubicin. [citation needed]
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.
"7+3" in the context of chemotherapy is an acronym for a chemotherapy regimen that is most often used today (as of 2014) as first-line induction therapy (to induce remission) in acute myelogenous leukemia, [1] [2] excluding the acute promyelocytic leukemia form, which is better treated with ATRA and/or arsenic trioxide and requires less chemotherapy (if requires it at all, which is not always ...
