alpha-Naphthoflavone, also known as 7,8-benzoflavone and 2-phenyl-benzo(h)chromen-4-one, is a synthetic^[1]^[2] flavone derivative. It can be prepared from 2-naphthol and cinnamaldehyde.^[3]

alpha-Naphthoflavone is a potent inhibitor of the enzyme aromatase, the enzyme that converts testosterone to estrogen.^[1]^[2] alpha-Naphthoflavone has been shown to cause abnormal testicular development in young chickens.^[4]
