Dutasteride-13C6
目录号 : GC43579An internal standard for the quantification of dutasteride
Cas No.:1217685-27-2
Sample solution is provided at 25 µL, 10mM.
Dutasteride-13C6 is intended for use as an internal standard for the quantification of dutasteride by GC- or LC-MS. Dutasteride is a dual inhibitor of 5α-reductase types I and II (Kis = 6 and 7 nM, respectively). Its inhibition is time-dependent with apparent Ki values of 17 and 4.3 nM at 10- and 30-minute reaction times, respectively. Dutasteride decreases prostate weight in a rat model of benign prostatic hypertrophy induced by testosterone after castration when administered daily for 28 days at doses of 0.045 mg/kg as a solution or 0.756 mg/kg in subcutaneous microspheres. It also decreases prostate weight in large probasin-large T antigen mice, a transgenic model of prostate cancer. Formulations containing dutasteride have been used in the treatment of benign prostatic hyperplasia.

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,
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 saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
