Target Point | Keap1-Nrf2 |
Passage | NF-κB |
Background | It is an inhibitor of Nrf2 pathway and can be used in the study of adjuvant chemotherapy compounds. |
Biological Activity | Brusatol是一种 Nrf2 通路抑制剂,可使多种癌细胞对 Cisplatin 和其他化疗活性分子敏感。Brusatol 通过抑制 Nrf2 介导的防御机制来增强化疗的疗效。]。 |
In Vitro | Nrf2抑制剂如Brusatol的潜在治疗应用是在具有组成型高水平转录因子的细胞中Nrf2途径组分的下调。 Brusatol通过不依赖于Keap1和蛋白酶体和自噬蛋白质降解系统的机制引起Nrf2的消耗。 Brusatol通过转录后机制在小鼠Hepa-1c1c7肝细胞瘤细胞中引起Nrf2蛋白的快速和短暂消耗。 Brusatol还抑制新鲜分离的原代人肝细胞中的Nrf2 [1]。为了探索Brusatol(BR)与CDDP组合可能的协同细胞毒性,该研究使用MTT试验研究了Brusatol和CDDP共处理对CT-26细胞活力的影响。用不同浓度的Brusatol(0.05,0.15,0.45,1.35,4.05和12.15μg/ mL)和CDDP(0.05,0.15,0.45,1.35,4.05和12.15μg/ mL)处理CT-26细胞48小时,或者单独或组合使用。用Brusatol和CDDP处理48小时后,CT-26细胞的活力以剂量依赖性方式降低,IC50值分别为0.27±0.01和1.44±0.22μg/ mL。当Brusatol与CDDP以1:1的恒定浓度比组合时,与单药治疗相比,细胞生长抑制显著增强; Brusatol和CDDP共处理的IC50值为0.19±0.02μg/ mL [2]。 |
In Vivo | 为了探索Brusatol在体内的抗癌作用,将在裸鼠中生长的A549异种移植物用作模型。向裸小鼠注射A549细胞以诱导肿瘤生长,然后单次ip注射2mg/kg Brusatol。在注射后24小时或48小时分离肿瘤。注射后24小时或48小时Nrf2蛋白水平显著降低,表明Brusatol能够到达肿瘤组织并抑制Nrf2通路。为了测量肿瘤生长,进行了两个不同的实验。在第一个实验中,一旦肿瘤大小达到平均230 mm3,DMSO,Brusatol(2 mg/kg),顺铂(2 mg/kg)或顺铂(2 mg/kg)和Brusatol(2 mg/kg)每隔一天腹腔注射联合治疗,共5次。单独的顺铂或Brusatol不显著抑制肿瘤生长,而在组合组中,肿瘤大小显著减少。在任何组中均未观察到显著的体重减轻[3]。 |
Cell Experiment | 将对数生长的CT-26细胞以4×103细胞/孔的密度接种到96孔板上。在37°C温育24小时后,新鲜培养基含有一系列浓度的Brusatol(0.05,0.15,0.45,1.35,4.05和12.15μg/ mL)和CDDP(0.05,0.15,0.45,1.35,4.05和12.15μg)以100μL/孔加入/ mL);每种浓度用于处理六个重复孔。在37℃温育48小时后,将细胞进一步与MTT(10mg/mL)在37℃温育4小时。然后除去上清液,用100μLDMSO溶解沉淀物。使用酶标仪在490nm的波长下测量吸光度。细胞毒性表示为抑制细胞生长50%的Brusatol和CDDP的浓度(IC 50值)。计算抑制率。通过将CT-26细胞单独或组合暴露于各种浓度的每种药剂48小时,研究了Brusatol与CDDP结合的可能的协同效应。使用CalcuSyn软件2.0 [2]评估协同效应。 |
Animal Experiment | 使用小鼠[3]无胸腺裸鼠。给4-6周龄的小鼠注射A549细胞。一旦肿瘤达到80 mm3(两次五次顺铂治疗方案)或280 mm3(单次五次顺铂治疗方案),将小鼠随机分成四组,腹腔注射DMSO,顺铂(2 mg)/kg),Brusatol(2 mg/kg),或每隔一天组合一次,共5次。在最初的五次顺铂治疗方案后,治疗停止1周,使小鼠恢复,然后重复第二次五次顺铂治疗方案[3]。 |
