| alpha-naphthoflavone | An extended flavonoid resulting from the formal fusion of a benzene ring with the h side of flavone. A synthetic compound, it is an inhibitor of aromatase (EC 1.14.14.14). | alpha-naphthoflavone |
| beta-naphthoflavone | An extended flavonoid resulting from the formal fusion of a benzene ring with the f side of flavone. | beta-naphthoflavone |

| morusin | An extended flavonoid that is flavone substituted by hydroxy groups at positions 5, 2' and 4', a prenyl group at position 3 and a 2,2-dimethyl pyran group across positions 7 and 8. | morusin |
| muromonab-cd3 | An extended flavonoid that consists of a pyranochromane skeleton that is 2H,6H-pyrano[3,2-g]chromen-6-one substituted by geminal methyl groups at position 2, a 2,4-dihydroxyphenyl group at position 8, a hydroxy group at position 5 and a prenyl group at position 7. Isolated from Morus alba and Morus species it exhibits anti-inflammatory activity. | cudraflavone B |
