体外研究 (In Vitro) |
在使用 16β-[18F]氟-5α-DHT (18-FDHT) 的竞争性测定中,去势抵抗性 LNCaP/AR 细胞中的恩杂鲁胺 (MDV3100) 对 AR 的亲和力高于 ICI 176334(AR 过表达)。对 LNCaP/AR 前列腺细胞,依折麦布没有激动作用。 Enzalutamide 通过与亲代 LNCaP 细胞中存在的合成雄激素 R1881 结合,抑制跨膜丝氨酸蛋白酶 2 (TMPRSS2) 和前列腺特异性抗原 (PSA) 的激活。突变 AR 蛋白(W741C,Trp741 改为 Cys)的转录活性受到 enzalutamide 的抑制 [1]。此外,恩杂鲁胺抑制共激活剂的募集和配体-受体复合物的核转位[2]。

体内研究 (In Vivo) |
当以 10 mg/kg 的剂量给予携带 LNCaP/AR 异种移植物的去势雄性小鼠时,恩杂鲁胺 (MDV3100) 显着减少肿瘤生长 [1]。当以 0.5 至 5 mg/kg 的剂量口服给药时,恩杂鲁胺的药代动力学表现出剂量依赖性[4]。

溶解度 (体内) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.38 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (5.38 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. View More
Solubility in Formulation 3: 2.5 mg/mL (5.38 mM) in 5% DMSO + 40% PEG300 + 5% Tween80 + 50% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. Solubility in Formulation 4: 15% DMSO +85% PEG 300 : 10mg/mL Solubility in Formulation 5: 10 mg/mL (21.53 mM) in 1% Tween-80 in PBS (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication (<60°C). 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! 6、如不确定怎么将母液配置成体内动物实验的工作液,请查看说明书或联系我们; 7、 以上所有助溶剂都可在 Invivochem.cn网站购买。 |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
