General description
7-Desacetoxy-6,7-dehydrogedunin (7DG) is structurally similar to HSP90 (heat shock protein 90) inhibitor, also known as gedunin.
Biochem/physiol Actions
7-Desacetoxy-6,7-dehydrogedunin (7DG) is a selective inhibitor of protein kinase R (PKR). 7DG appears to directly interact with the C-terminal half of PKR, and unlike C16, does not bind the ATP catalytic pocket. 7-Desacetoxy-6,7-dehydrogedunin completely protected macrophages from anthrax lethal toxin (LT)-induced pyroptotic cell death, a model for inflammasome-mediated caspase-1 activation, with an (IC50) of 5 μM, showing a role for PKR in pyroptosis.

Formation of the inflammasome, a scaffolding complex that activates caspase-1, is important in numerous diseases. Pyroptotic cell death induced by anthrax lethal toxin (LT) is a model for inflammasome-mediated caspase-1 activation. We discovered 7-desacetoxy-6,7-dehydrogedunin (7DG) in a phenotypic screen as
