Brusatol is an Nrf2 inhibitor isolated from Brucea javanica and exhibits significant tumor inhibition in multiple cancers through decreased resistance to cancer oxidative stress injury[1,2,3]. Brusatol is confirmed to inhibit the Nrf2-Notch1 pathway, increse p-P38, LC3, Beclin 1 and p-JNK expression, downregulate BRF2, IGFBP-2, P62 and CD151[3].
In vitro, Brusatol (20, 50, 100, and 200nM; 0, 24, 48, 72, and 96h) treatment at the zygotic stage prevented the early embryo development in Kunming mice embryos[4]. Brusatol (1 and 100nM; 72h) shows an antitumor effect in an acute lymphoblastic leukemia (KOPN-8 cells) model triggered by reactive oxygen species accumulation[5]. Brusatol (0.31 to 10µM; 24 or 48h) results in breast cancer retardation via Nrf2 inhibition in breast cancer cell lines[6].
In vivo, Brusatol (2mg/kg; every 48h; 5 weeks; i.p.) hinders the progression of bladder cancer by Chac1/Nrf2/SLC7A11 pathway[7]. Brusatol (NSC 172924) sensitizes endometrial hyperplasia and cancer to progestin by suppressing NRF2-TET1-AKR1C1-mediated progestin metabolism in a Brusatol (NSC 172924)-treated (10nmol/l; 3 days) endometrial cancer cell (Ishikawa and ECC1) injected nude mice model[8].

Protocol
| Cell experiment [1]: | |
Cell lines | MCF-7, MDA-MB-231, or MDA-MB-468 |
Preparation Method | Various BC cells (MCF-7, MDA-MB-231, or MDA-MB-468) (1.0 × 104cells in 100µL DMEM with 10% FBS) were seeded in 96-well plates and cultured in an incubator at 37 °C with 5% CO2 and 90% relative humidity. Following this, when cell confluence reached about 60 to 70% (36h later), the cells were exposed to gradual concentrations of brusatol (ranging from 0.31 to 10µM) for 24 or 48h. Following this treatment, cell viability was measured using sulforhodamine B (SRB) and MTT(3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) assays. |
Reaction Conditions | 0.31 to 10µM; 24 or 48h |
Applications | The effect of two low/non-toxic concentrations (19.5 and 78nM) of brusatol did not demonstrate any significant effect on cell viability. Brusatol provoked a significant decrease in BC cell viability; however, this effect was not dose- or time-dependent. The highest cytotoxic effects of brusatol were observed at 24 and 48h of treatment. |
| Animal experiment [2]: | |
Animal models | male BALB/c-nude mice |
Preparation Method | T24 cells were injected subcutaneously into mice at a concentration of 1×106 cells per mouse. Three mice were randomly allocated into two groups, consisting of nude mice. The experimental groups were administered intraperitoneal injections of brusatol at a dosage of 2mg/kg every 48h, whereas the control groups were given injections of normal saline. Following a treatment duration of 5 weeks, the mice were administered anesthesia and subsequently euthanized to facilitate additional analysis. Sodium pentobarbital (30mg/kg) was administered as the anesthetic drug. |
Dosage form | 2mg/kg; every 48h; 5 weeks |
Applications | The tumor size of mice treated with brusatol was significantly reduced. |
