    <description> belongs to the class of organic compounds known as naphthofurans. Naphthofurans are compounds containing a furan ring fused to a naphthalene moiety. Furan is a 5 membered- ring aromatic ring with four carbon and one oxygen atoms. Naphthalene is a polycyclic aromatic hydrocarbon  made up of two fused benzene rings.</description>
