Elacridar是一种P-糖蛋白的强效抑制剂,其IC50值为193 nM。[1]
P-糖蛋白(渗透性糖蛋白)是一种重要的膜蛋白,属于MDR/TAP亚家族的跨膜糖蛋白,分子量约为170kDa,可将许多外源性物质从细胞泵出。P-糖蛋白主要在特定的细胞类型如胰腺、肝脏、结肠和肾脏细胞中表达。该分子在N端包含6个跨膜结构域,在大的细胞质结构域中也包含一个ATP结合位点。P-糖蛋白在胞质一侧结合底物,当ATP与胞质一侧结合时,底物从细胞中排出。P-糖蛋白可将毒素或药物泵回肠腔,在肝细胞中则可泵入胆管。在一些癌细胞中,P-糖蛋白过表达,其与癌细胞的多重耐药性有关。[2]
在过表达P-糖蛋白的MDCKII 细胞中,浓度为1 μM的elacridar可以显著地抑制P-糖蛋白的活性。[3]在亲代MDCK-II细胞中,浓度为5 μM的elacridar可完全抑制极化sunitinib的转运。[4] Elacridar在体外不能抑制多种人细胞色素P450的酶活。使用elacridar进行小鼠口服和腹腔微乳液给药,剂量为10 mg/kg,其绝对生物利用度分别为约0.47和1.3。[3]给小鼠使用剂量为10 mg/kg的elacridar也会显著增加sunitinib在脑部的积累。[4]

一般建议 | 不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
细胞实验[1]: | |
细胞系 |
人肾癌细胞系786-O和人乳腺癌细胞系MCF-7 |
溶解方法 |
在DMSO中的溶解度大于56.4 mg/mL。为了获得更高的浓度,可以将离心管在37℃加热10分钟和/或在超声波浴中震荡一段时间。原液可以在-20℃以下储存几个月。 |
反应条件 |
5 μM,24 h |
应用 |
Elacridar是P-糖蛋白的抑制剂,也可抑制ABCG2。在786-O细胞中,Elacridar显著加强sunitinib诱导的细胞毒性。P-糖蛋白功能实验表明,Elacridar可抑制P-糖蛋白的活性。 |
动物实验[2]: | |
动物模型 |
10-14周的野生型、Abcb1a/1b-/-、32Abcg2-/-27和Abcb1a/1b/Abcg2-/-小鼠,均具有99%以上的FVB遗传背景 |
剂量 |
口服给药,100 mg/kg |
应用 |
在野生型小鼠中,Elacridar显著增加sunitinib的脑累积(12倍),相当于sunitinib在Abcb1a/1b/Abcg2-/-小鼠中的水平。在Abcb1a/1b/Abcg2-/-小鼠中,Elacridar对sunitinib的脑浓度无显著影响。 |
注意事项 |
请测试所有化合物在室内的溶解度,实际溶解度和理论值可能略有不同。这是由实验系统的误差引起的,属于正常现象。 |
