Class Information
Number: 546/31
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen as the only ring hetero atoms (class 540, subclass 1) > Hetero ring is six-membered consisting of one nitrogen and five carbons > Polycyclo ring system having the six-membered hetero ring as one of the cyclos > Octacyclo ring system having the six-membered hetero ring as one of the cyclos > Plural ring hetero atoms in the octacyclo ring system (e.g., flavanthrone, cepharanthrine, etc.)
Description: Compounds wherein the octacyclo ring system includes at least one ring hetero atom in addition to the ring nitrogen of the six-membered hetero ring.
