Any condition in which the main influencing factor is a naturally occurring compound or related synthetic analog with a molecular structure based on the cyclopenta[a]phenanthrene carbon skeleton, that is, a phenanthrene, to the a side of which a three-carbon fragment is fused. According to the definition at the Chemical Entities of Biological Importance (ChEBI) database, 'By extension, one or more bond scissions, ring expansions and/or ring contractions of the skeleton may have occurred' which expands the class to include molecules based on but not containing the cannonical arrangement of four fused cycloalkane rings.
