cytonic acid A

CHEBI:65717 ·resolve ·ANTIVIRAL ·EXACT SEEDED

A benzoate ester obtained by the formal condensation of the hydroxy group at position 4 of 4-[(2,4-dihydroxy-6-propylbenzoyl)oxy]-2-hydroxy-6-propylbenzoic acid with the carboxy group of 2,4-dihydroxy-6-pentylbenzoic acid (olivetolic acid). It is isolated from the endophytic fungi Cytonaema and acts as an inhibitor of human cytomegalovirus (hCMV) protease. — ChEBI
