Epirubicin hydrochloride (4'-Epidoxorubicin hydrochloride), a semisynthetic L-arabino derivative of doxorubicin, has an antineoplastic agent by inhibiting Topoisomerase[1]. Epirubicin hydrochloride is a Forkhead box protein p3 (Foxp3) inhibitor and inhibits regulatory T cell activity[2].

IC50 & Target[1]



In Vitro

Epirubicin hydrochloride (4'-Epidoxorubicin hydrochloride), like doxorubicin, exerts its antitumor effects by complex with DNA, resulting in damage to DNA and interference with the synthesis of DNA, RNA, and proteins. Epirubicin hydrochloride may also affect the integrity and activity of cellular membranes. Maximal cell kill caused by Epirubicin hydrochloride occurs during the S phase of the cell cycle. With higher concentrations effects are also seen in early G2 as well as G1 and M phases[1].
Epirubicin hydrochloride display antineoplastic activity against most cancer cells. Epirubicin hydrochloride is cytotoxic to Hepatoma G2 cells with IC50 of 1.6 μg/mL at 24 hr. 1.6 μg/mL Epirubicin hydrochloride induces apoptosis of Hep G2 cells, and higher activity of catalase by 50%, Se-dependent glutathione peroxidase by 110%, Cu, Zn-superoxide dismutase by 172% and Mn-superoxide dismutase by 135%. Epirubicin hydrochloride increases the cellular expression of NADPH-CYP 450 reductase, and reduces GST-π expression[3].

In Vivo

Epirubicin hydrochloride (4'-Epidoxorubicin hydrochloride) are clinically active against a broad range of tumor types, including breast cancer, malignant lymphomas, soft tissue sarcomas, lung cancer, pleural mesothelioma, gastrointestinal cancer, head and neck cancer, ovarian cancer, prostatic carcinoma, transitional bladder carcinoma and so on[4].
Epirubicin hydrochloride at a dose of 3.5 mg/kg suppresses tumor mass of human breast tumor xenograft R-27 by 74.4 %[5].

Cell Assay

Hep G2 cells (500 cells/well, monolayer) are plated in a 96-well plate. The next day the cells are treated with Epirubicin in the medium. At the end of the incubation periods, 15% volume of MTT dye solution is added. After 1 hr of incubation at 37°C, an equal volume of solubilization/stop solution (dimethylsul-foxide) is added to each well for an additional 1 hr incubation. The absorbance of the reaction solution at 570 nm is recorded.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
