Chemical Structure
Variegatic acid
- CAS No.: 20988-30-1
- Formula:C18H12O9
- Molecular Weight:372.29
IUPAC Name: (E)-2-(3,4-dihydroxyphenyl)-2-(4-(3,4-dihydroxyphenyl)-3-hydroxy-5-oxofuran-2(5H)-ylidene)acetic acid
InChIKey: MRRYHTCWZKZVIH-JQIJEIRASA-N
SMILES: C(\C(O)=O)(=C/1\C(O)=C(C(=O)O1)C2=CC(O)=C(O)C=C2)/C3=CC(O)=C(O)C=C3
Biological Activity: Variegatic acid is a secondary metabolite derived from basidiomycete fungi. Variegatic acid is a PKCβ1 inhibitor with an IC₅₀ of 36.2 μM. Variegatic acid inhibits antigen- or calcium ionophore-induced β-hexosaminidase release (IC₅₀ values of 10.4 μM and 22.2 μM, respectively) and TNF-α secretion (IC₅₀ values of 16.8 μM and 20.1 μM, respectively). Variegatic acid suppresses the enzymatic activity of calcium-activated PKCβ1 and reduces Fe(III) to Fe(II) in a pH-dependent manner, enabling the generation of hydroxyl radicals (·OH) through reaction with H₂O₂, which facilitates the degradation of lignocellulose. Variegatic acid is useful for studying biological degradation and allergic responses.
