Number: 514/263.23
Name: Drug, bio-affecting and body treating compositions > Designated organic active ingredient containing (doai) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., o,s,se or te) or nitrogen as the only ring hetero atoms doai > Hetero ring is six-membered consisting of two nitrogens and four carbon atoms (e.g., pyridazines, etc.) > 1,3-diazines (e.g., pyrimidines, etc.) > Polycyclo ring system having 1,3-diazine as one of the cyclos > Bicyclo ring system having the 1,3-diazine as one of the cyclos > Exactly four ring nitrogens in the bicyclo ring system > Purine (including hydrogenated) > Additional hetero ring attached directly or indirectly to the purine ring system by nonionic bonding > The additional hetero ring consists of carbon and chalcogen as the only ring members
Description: Subject matter wherein the additional hetero ring includes at least one atom each of chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) and carbon, and contains no other elements as ring members.
