Background:

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].
