Celastramycin A

Catalog No.: A47189
Antibiotic
Celastramycin A is an antibiotic derived from Streptomyces MaB-QuH-8, known for its significant antimicrobial activity against a variety of gram-negative bacteria and mycobacteria, with minimum inhibitory concentrations (MICs) ranging from 0.05 to 3.1 μg/ml. This compound exhibits immunosuppressive effects, evidenced by its ability to modulate immune responses in ex vivo Drosophila and human models, demonstrating an IC50 of 0.008 μg/ml through the immune deficiency pathway and inhibiting TNF-α signaling. Additionally, Celastramycin A effectively reduces IL-8 production in human umbilical vein endothelial cells (HUEVCs), with an IC50 of 0.06 μg/ml, making it a valuable tool for research in microbial resistance and immune modulation.
