Etymology: Daunorubicin is a blend of two earlier antibiotic names, "daunomycin" and "rubidomycin," because the drug was discovered independently by two separate laboratory groups. Each team had already named its find before the two names were combined into a single term for the one compound they had both isolated. "Daunomycin" points to the Italian and French work that gave it its first name, while "rubidomycin" reflects the red colour of the compound and the "-mycin" ending that marks an antibiotic. The second name was taken from "rubidomycin," so the new word keeps the red-coloured antibiotic lineage in its ending. Its "-rubicin" ending links it to the broader anthracycline family, which takes its own name from the anthracene ring structure found in these drugs.
