Skyrin

Description: Skyrin is a fungal metabolite characterized by a bisanthraquinone structure. It interferes with glucagon signaling through adenylate cyclase without binding to the glucagon receptor. At 10 µM, skyrin reduces both glucagon-stimulated cAMP production and glycogenolysis. It does not interfere with epinephrine or glucagon-like peptide 1 effects on these parameters.[1]. Target: Others. Smiles: O=C1C2=CC(=CC(O)=C2C(=O)C=3C(O)=CC(O)=C(C13)C=4C(O)=CC(O)=C5C(=O)C6=C(O)C=C(C=C6C(=O)C54)C)C. References: Parker, J.C., McPherson, R.K., Andrews, K.M., et al.
