Description:	Idarubicin hydrochloride is an anthracycline antileukemic drug. It inhibits the topoisomerase II interfering with the replication of DNA and RNA transcription.
In Vitro:	The IC50 of idarubicin is 3.3±0.4 ng/mL on MCF-7 monolayers and 7.9±1.1 ng/mL in multicellular spheroids[1]. Idarubicin has shown a greater cytotoxicity than daunorubicin or doxorubicin in various in vitro systems. This has been attributed to a better ability of idarubicin to induce the formation of topoisomerase II -mediated DNA breaks[2].Idarubicin is about 57.5-fold and 25-fold more active than doxorubicin and epirubicin, respectively[3]. Idarubicin produces a concentration-dependent reduction in cell growth, with an IC50 value of approximately 0.01 μM. Idarubicin produced a concentration-dependent inhibition of DNA synthesis[4].
Cell Assay:	Stock solutions of idarubicin hydrochloride is dissolved in distilled water (1 mg/mL). MCF-7 monolayer are exposed to idarubicin or its metabolite idarubicinol at 0.01, 0.1, 1, 10, 100, and 1000 ng/mL for 24 hours. Multicellular spheroids are exposed to the same range of idarubicin　and idarubicinol concentration as monolayers (0.01-1000 ng/mL) for 24 h and, in separate experiments, at the drug concentration of 100 ng/mL for 6, 12, 24 and 48 h. The inhibition of cell proliferation is determined by counting the viable cells with an hemocytometer. Results are expressed as percentage of cell survival vs. control cultures[1].
