A number of N6-(N-arylcarbamoyl)-2-substituted-9-benzyl-8- azaadenines, obtained by a modification of the synthetic scheme used to prepare selective A1 ligands, by only three or two steps, are described. At first we prepared a series

Some new 1,2,3-triazolo[4,5-e]-1,2,4-triazolo[3,4-c]pyrimidines were prepared starting from the corresponding 1,2,3-triazolo[4,5-d]pyrimidines via the formation of the 1,2,4-triazole ring. Thus suitable hydrazino derivatives 6 were condensed with triethyl orthoformate, triethyl orthoacetate and triethyl orthobenzoate to give the expected tricyclic derivatives 7, 8 and 9. Intramolecular cyclization of the ethoxycarbonylhydrazino derivatives 10 gave the tricyclic compounds 11 bearing an hydroxyl group in the 3 position. The v-triazolo-s-triazolopyrimidine derivatives were tested towards the A1 and A(2A) adenosine receptors in binding assays, but they did not show any receptor affinity.

Novel 5-amino or substituted amino 1,2,3-triazoles are disclosed as having anticoccidial activity. The compounds are useful for controlling coccidiosis when administered in minor quantities to animals, in particular to poultry, usually in admixture with animal sustenance.
