Caspofungin-d4 (acetate) is intended for use as an internal standard for the quantification of caspofungin by GC- or LC-MS. Caspofungin is an antifungal compound that is classified as an echinocandin, as it acts by noncompetititvely inhibiting the enzyme 1,3-β glucan synthase and preventing the synthesis of glucan in the fungal cell wall.1 It is effective against disseminated or invasive aspergillosis and candidiasis.2,3 Caspofungin has a 50% minimum effective concentration against Aspergillus spp. of 0.015 μg/ml.4 It does not antagonize other antifungal compounds, like amphotericin B, and, in some cases, may show additive or synergistic activity.1,3,5

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。
