产品描述
ARCC-4 是一种基于 PROTAC 技术的纳摩尔雄激素受体 (AR) 降解剂,D50 为 5 nM。 ARCC-4 是一种基于恩杂鲁胺的 von Hippel-Lindau (VHL) 招募 AR PROTAC。 ARCC-4 可有效降解与抗雄激素研究相关的 AR 突变。
生物活性&实验参考方法
体外研究 (In Vitro)
当 ARCC-4 改善 AR 和 VHL 之间的蛋白质-蛋白质反应时,三促进聚合物复合物更容易结合[1]。 AR 可有效降解 -4(0.1-10,000 nM;20 小时),D50 为 5 nM,Dmax 大于 95% [1]。含有 ARCC-4(100 nM;12 小时)的模具表现出 AR。 ARCC-4 不会阻碍 PR-A 或 PR-B,但它几乎仅通过有色体色素调节 AR [1]。 ARCC-4 可有效抑制具有临床意义的 AR 突变 [1]。 ARCC-4 在高雄激素水平下仍然发挥作用 [1]。

请根据您的实验动物和给药方式选择适当的溶解配方/方案:
1、请先配制澄清的储备液(如:用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液,按从左到右的顺序依次添加助溶剂,澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明,并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀/澄清;向上述体系中加入50 μL Tween-80,混合均匀/澄清;然后继续加入450 μL ddH2O (或 saline)定容至 1 mL;

3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出,可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果,工作液请现配现用!
