| Bioactivity | Mitoxantrone is a potent topoisomerase II inhibitor. Mitoxantrone also inhibits protein kinase C (PKC) activity with an IC50 of 8.5 μM. Mitoxantrone induces apoptosis of B-CLL (B-chronic lymphocytic leukaemia) cells. Mitoxantrone shows antitumor activity[1][2][3][4]. Mitoxantrone also has anti-orthopoxvirus activity with EC50s of 0.25 μM and and 0.8 μM for cowpox and monkeypox, respectively[5]. |
| Invitro | Mitoxantrone inhibits PKC in a competitive manner with respect to histone H1, and its Ki value is 6.3 μM and in a non-competitive manner with respect to phosphatidylserine and ATP[1].Mitoxantrone (0.5 μg/mL, 48 h) induces a decrease in B-CLL cells. Mitoxantrone induces DNA fragmentation and the proteolytic cleavage of poly(ADP-ribose) polymerase (PARP), demonstrating that the cytotoxic effect of Mitoxantrone is due to induction of apoptosis[2].Mitoxantrone shows cytotoxicity to human breast carcinoma cell lines MDA-MB-231 and MCF-7 with IC50 values of 18 and 196 nM, respectively[3]. |
