SM 5887 Usage And Synthesis
Description
small and small-cell lung cancers. Amrubicin, a completely synthetic anthracycline derivative, mediates its growth inhibitory action via topoisomerase II inhibition. It is activated in viva by the formation of its 13-OH metabolite, amrubicinol, via reaction with carbonyl reductase. In contrast to doxorubicin and daunorubicin whose metabolites are inactive in the blood, amrubicinol is 10-100 fold more cytotoxic than amrubicin. In phase II clinical trials, amrubicin showed antitumor activity against non-small-cell lung cancers (response rate exceeding 20%) and against untreated extensive stage small-cell-lung cancers (response rate 78.8%). Amrubicin demonstrated a smaller distribution-volume, a shorter half-life in mice and also less chronic cardiotoxicity in preclinical studies compared to doxorubicin. Amrubicin was generally well tolerated with major adverse events being anaemia, leucopenia, thrombocytopenia and neutropenia.

Uses
Amrubicin (SM-5887) hydrochloride is a DNA topoisomerase II inhibitor, used for the research of cancer.
brand name
Calsed
in vivo
Amrubicin (SM-5887) (25 mg/kg, i.v.) exhibits significant antitumor activities against both SCLC tumors, Lu-24 and Lu-134, with T/C-values (comparing the mean tumor growth rates of the treated group with those of the control group for each day that the tumors are measured) at day 14 of 17% and 9%, respectively. Amrubicin (SM-5887) (25 mg/kg, i.v.) in combination with cisplatin and irinotecan significantly inhibits the growth of tumors compared to amrubicin alone in mice bearing LX-1 tumor cells. Amrubicin (SM-5887) alone or combined with tegafur and uracil also suppresses tumor growth in human cancer xenograft models[2].
