title: Synthesis and pharmacological activity of some 9-aryl-8-azapurine derivatives.
abstract: Because of the biological interest of 8-azaanologous of purine bases, the preparation of some 8-azapurines (IV) and (V), substituted in 9 position with aryl groups, is described. Compounds were obtained by closure of a pyrimidine nucleus on performed 5-amino-1,2,3-triazole derivatives. Some substances, subjected to pharmacological screening, showed an interesting antiallergic activity.
