Description

Dehydrobruceine B, a quassinoid, can be isolated from Brucea javanica. Dehydrobruceine B shows a synergistic effect with Cisplatin (HY-17394) to induce apoptosis via mitochondrial method. Dehydrobruceine B increases apoptosis-inducing factor (AIF) and Bax expression and suppresses Keap1-Nrf2[1].

In Vitro

Dehydrobruceine B (1 μM; 48 h) and Cisplatin (3-18 μM; 48 h) combination synergizes the cytotoxic and apoptotic effects in A549 cells[1].
Dehydrobruceine B (1 μM; 24 h) induces excessive generation of intracellular ROS in Cisplatin (3 μM, 6 μM; 24 h)-treated A549 cells[1].
Dehydrobruceine B (1 μM; 24 h) increases depolarization of mitochondrial membrane potential (MMP) and translocation of cytochrome c in Cisplatin (3 μM, 6 μM; 24 h)-treated A549 cells[1].
Dehydrobruceine B (1 μM; 24 h) enhances the change of anti-apoptotic and pro-apoptotic protein levels in A549 cells[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[1]

Cell Line: A549 cells
Concentration: 1 μM; with or without Cisplatin
Incubation Time: 48 hours
Result: Upregulated the protein level of Bax, while downregulated the levels of Bcl-2 and Bcl-xL.
Enhanced caspase activation and PARP cleavage.

Apoptosis Analysis[1]

Cell Line: A549 cells
Concentration: 1 μM; with or without Cisplatin
Incubation Time: 48 hours
Result: Inhibited cell viability with 9 μM and 18 μM Cisplatin, respectively.
Induced cell apoptosis with 3 μM and 6 μM Cisplatin, respectively.

Immunofluorescence[1]

Cell Line: A549 cells
Concentration: 1 μM; with or without 3 μM and 6 μM Cisplatin, respectively
Incubation Time: 24 hours
Result: Resulted apoptosis-inducing factor (AIF) translocated from cytosol into nucleus dramatically in the co-treatment condition.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
