Rhodamine 123 is a fluorescent dye (λex=503 nm, λem=527 nm). The intensity of R123 fluorescence has a peak at concentration of 50 μM, and decreases to zero at higher concentrations due to self-quenching.

Deferitazole (FBS 0701) is a novel and orally active, selective and high affinity iron chelator.

A derivative of EDTA that chelates iron and reduces the number of metal ions complexed with anthracycline and, consequently, decrease the formation of superoxide radicals.
