Abstract
In the presence study tetrazine naming according four naming system of heterocyclic nomenclature as common nomenclature, method of replacement, Hantzsch-Widmann Systematic or IUPAC and fused system. each system contain special rules for naming which are different from the other as following explaining with example structures. Tetrazine pharmacological activity as Antibacterial, antifungal, anticancer, antiviral, antimalarial, and antimicrobial activities found in several tetrazine compounds. Some tetrazineees derivatives are not bad analgesics and anti-inflammatories, other 1,2,4,5 -tetrazines exhibit significant antimalarial activity. A number of tetra hydro-s-tetrazines have been shown to have antibacterial and antifungal properties, with several 1, 4-dihydro-s-tetrazine derivatives possessing antiviral and anticancer properties.
