Clofazimine-d7 is intended for use as an internal standard for the quantification of clofazimine by GC- or LC-MS. Clofazimine is an antimycobacterial compound with MICs ranging from 0.03 to 0.12 μg/ml against clinical isolates of M. paratuberculosis.1 It also has activity against 80 isolates of M. fortuitum, M. chelonae, and M. fallax (MICs = ≤0.25-8 μg/ml).2 Clofazimine (25 mg/kg per day) reduces the number of M. tuberculosis-infected cells in the spleen and lungs of mice infected with the multidrug-resistant clinical isolate strain CNL.3 Formulations containing clofazimine have been used for the treatment of leprosy and drug-resistant tuberculosis.4

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。
