  2. Bcl-2 Family Keap1-Nrf2 Apoptosis
  3. Dehydrobruceine B

Dehydrobruceine B 是一种苦木素,可从鸦胆子 (Brucea javanica) 中分离得到。Dehydrobruceine B 与 Cisplatin (HY-17394) 通过线粒体途径,协同诱导细胞凋亡 (apoptosis)。Dehydrobruceine B 还增加凋亡诱导因子 (AIF) 和 Bax 表达,抑制 Keap1-Nrf2

生物活性

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].

体外研究
(In Vitro)

Dehydrobruceine B (1 μM; 48 h) 和 Cisplatin (3-18 μM; 48 h) 在 A549 细胞中具有协同作用,致使细胞毒性和凋亡效应[1]
Dehydrobruceine B (1 μM; 24 h) 在 Cisplatin (3 μM, 6 μM; 24 h) 处理的A549细胞中,诱导胞内 ROS 产生[1]
Dehydrobruceine B (3 μM, 6 μM; 24 h) 在 Cisplatin (3 μM, 6 μM; 24 h) 处理的A549细胞中,促进线粒体膜电位 (MMP) 的去极化和细胞色素 c 的易位[1]
Dehydrobruceine B (1 μM; 24 h) 增强 A549 细胞抗凋亡和促凋亡蛋白水平的变化[1]

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.
