Molarity Calculator

Celastramycin A isomer is an isomer of Celastramycin A (HY-122292), an antibiotic against Gram-negative bacteria and Mycobacterium tuberculosis with an MIC of 0.05-3.1 μg/mL. Celastramycin A exerts immunosuppressive effects in Drosophila ex vivo via the immunodeficiency pathway (IC50 of 8 ng/mL), inhibits human innate immune responses via the TNF-α pathway, and inhibits IL-8 production in HUEVC with an IC50 of 60 ng/mL.
