Number: 544/250
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 having two or more ring hetero atoms of which at least one is nitrogen (e.g., selenazines, etc.) > The six-membered hetero ring consists of two nitrogens and four carbons (e.g., 1,2-diazines, etc.) > 1,3-diazines > Polycyclo ring system having the diazine ring as one of the cyclos > Tricyclo ring system having the diazine ring as one of the cyclos > Three or more ring hetero atoms in the tricyclo ring system
Description: Compounds wherein the tricyclo ring system includes at least one ring hetero atom in addition to the two ring nitrogens of the six-membered hetero ring.
