Mitoxantrone-d8 dihydrochloride is deuterated labeled Mitoxantrone dihydrochloride (HY-13502A). Mitoxantrone dihydrochloride is a potent topoisomerase II inhibitor. Mitoxantrone dihydrochloride also inhibits protein kinase C (PKC) activity with an IC50 of 8.5 µM. Mitoxantrone dihydrochloride induces apoptosis of B-CLL (B-chronic lymphocytic leukaemia) cells. Mitoxantrone dihydrochloride shows antitumor activity[1][2][3][4]. Mitoxantrone dihydrochloride also has anti-orthopoxvirus activity with EC50s of 0.25 µM and and 0.8 µM for cowpox and monkeypox, respectively[5].
