生物活性:
Pixantrone (BBR 2778 (free base)) hydrochloride, a mitoxantrone analog, is a topoisomerase II inhibitor and DNA intercalator, with anti-tumor activity.
体内研究:
Pixantrone (i.v., 27 mg/kg, every 7 days, three times) hydrochloride does not worsen pre-existing moderate degenerative cardiomyopathy, causes minimal cardiotoxic in mice following repeated treatment cycles and results in less mortality than mitoxantrone in doxorubicin-pretreated mice.Pixantrone (i.v., 16.25 mg/kg, every week, three times) hydrochloride modulates Lymph node cells (LNC) responses, affacts T cell subpopulations in TAChR-immunized Lewis rats and also shows preventive and therapeutic effect in experimental autoimmune myasthenia gravis (EAMG) rats.
体外研究:
Pixantrone (0-10 μM, 72 h) hydrochloride induces cell death in multiple cancer cell lines independent of cell cycle perturbation.Pixantrone (25-500 nM, 24 h) hydrochloride can induce DNA damage, hinder chromosome segregation, and induce severe chromosomal aberrations and mitotic catastrophes in PANC1 cells.Pixantrone (0-100 μM, 72 h) hydrochloride potently inhibits growth of human leukemia K562 cells, etoposide-resistant K/VP.5 cells, MDCK and ABCB1-transfected MDCK/MDR cells with IC50s of 0.10 μM, 0.56 μM, 0.058 μM and 4.5 μM, respectively.Pixantrone (0.01-0.2 μM) hydrochloride leads to a concentration-dependent formation of linear DNA through acting on topoisomerase IIα and produces semiquinone free radicals in an enzymatic reducing system, although not in a cellular system, most likely due to low cellular uptake.Pixantrone (0.01-10 μM) hydrochloride shows potent inhibitory activities against rat 97-116 peptide-specific T cell proliferation.
