Chemical Structure
Celastramycin A
- CAS No.: 188988-62-7
- Formula:C17H18Cl3NO3
- Molecular Weight:390.69
IUPAC Name: (3-chloro-5-hexyl-2,6-dihydroxyphenyl)(4,5-dichloro-1H-pyrrol-2-yl)methanone
InChIKey: VPAMZQVPJOAFJG-UHFFFAOYSA-N
SMILES: O=C(C1=C(O)C(CCCCCC)=CC(Cl)=C1O)C2=CC(Cl)=C(Cl)N2
Biological Activity: Celastramycin A is an antibiotic isolated from Streptomyces MaB-QuH-8, which exhibits antimicrobial activity against series of gram-negative bacteria and mycobacteria, with MICs between 0.05-3.1 μg/ml[1]. Celastramycin A exhibits immunosuppressing efficacy in ex vivo Drosophila through immune deficiency pathway (IC50 of 0.008 μg/ml), inhibits the immunoresponse in human innate immunity through TNF-α signaling, inhibits IL-8 production in HUEVCs with IC50 of 0.06 μg/ml[2].
