Celastramycin A is an antibiotic that inhibits the growth of bacteria and mycobacteria and is also a potent innate immune suppressor [1][2].
Celastramycin A is a benzoyl pyrrole-type compound isolated from endophytic bacteria Streptomyces MaB-QuH-8 living in plants of the Celastraceae family. Celastramycin A exhibited high activity against a series of multiresistent bacteria and mycobacteria [1]. Celastramycin A inhibited the growth of Gram-positive bacteria and mycobacteria with minimal inhibitory concentration (MIC) as low as 0.05 μg/ml [1]. In the ex vivo Drosophila culture system, Celastramycin A showed a potent immunosuppressive effect with IC50 value of 0.008 μg/mL. In human umbilical vein endothelial cells (HUVECs), Celastramycin A potently inhibited the production of IL-8 with IC50 value of 0.06 μg/mL. So Celastramycin A could be used as a lead compound for novel immunosuppressive agents [2].

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。
