Berubicin
Based on 1 Customer Validation
Berubicin (RTA 744 free base) is a Doxorubicin (HY-15142A) analog that can cross the blood-brain barrier. Berubicin inhibits P-gp and MRP1-mediated efflux and suppresses glioblastoma multiforme (GBM). Berubicin exerts toxic effects on leukemia cells by activating nuclear factor κB (NF-κB) and induces apoptosis in neuroblastoma cells. Berubicin can be used in the study of tumors related to the nervous system.

Berubicin (0.1-10 μM, 0-5 d) is more effective than Doxorubicin (Dox) in inhibiting SH-SY5Y cell growth[2].
Berubicin (0-10 μM, 0-48 h) induces apoptosis at the lower drug concentrations through caspase-9 and -3-dependent pathways and activating NF-κB, while other mechanisms of cell death may predominate at higher concentrations in SH-SY5Y cells[2].
Berubicin (0-100 μM, 24 h) inhibits three AML cell lines K562, KBM-3, OCIM2 and KBM-5 cells with IC50s of 0.18, < 0.05, < 0.05 μg/mL and 0.5 μM, and induces cell apoptosis in cultured human acute lymphoblastic leukemia (ALL) CEM cells at 0.05 μM[3][4].
Berubicin (0-10 μM, 0-8 h) is more active than Dox in inhibiting DNA synthesis (IC50 = 0.2 μM), activating NF-κB and degradation of IkBα of KBM-5 cells[4].

-
Cell Line:SH-SY5Y cells
-
Concentration:0.05, 0.5 and 5 μM
-
Incubation Time:48 h
-
Result:Induced significantly higher apoptosis at 500 nM than Dox, but higher concentrations of the drug reduced the apoptosis-inducing effect.
-
Cell Line:SH-SY5Y cells
-
Concentration:0, 0.1, 1 and 10 μM
-
Incubation Time:0, 0.5, 1, 2, 4, 6, 8, 12, 24 h
-
Result:Observed a caspase-9 cleavage band as early as 0.5 h after drug treatment and accumulated to highest levels after 12 h, and caspase-3 cleavage was seen as early as 8 h.
Did not express caspase 8, and there was no increase or decrease in caspase 7 expression.
Significantly increased p53 levels, whereas Dox had no such effect and p21 expression increased with increased p53.
Significantly reduced mitochondrial AIF and nuclear AIF accumulation increases over time.
Showed 50 times more potent than Dox in activating NF-κB.
Downregulated the expression of IκBα, Bcl-w, Bcl-XL and cyclin D1.
-
Cell Line:KBM-5 cells
-
Concentration:0, 0.1, 1, 10 μM
-
Incubation Time:0, 5, 10, 15, 30, 60, 120, 240, 480 min
-
Result:Was most active, reaching maximum activation in activating NF-kβ and degradation of IkBαat a 1 μM concentration, and Doxorubicin least active, reaching maximum at 50 μM.
