7-oxohernangerine

CHEBI:66841 ·resolve ·ANTIVIRAL ·EXACT SEEDED

An oxoaporphine alkaloid that is 7H-dibenzo[de,g]quinolin-7-one substituted by a methylenedioxy group across positions 1 and 2, a methoxy group at position 11 and a hydroxy group at position 10. Isolated from Hernandia nymphaeifolia and Lindera chunii, it exhibits activity against HIV-1 integrase. — ChEBI
