Abstract: Intramolecular N-7 alkylation of 6-substituted purines gave rise to a new series of tricyclic purine derivatives. The new compounds were evaluated for their cytotoxicity, their antileishmania activity together with their capacity to modulate NO production in macrophages. As a result compound 1 exhibited a modest activity against KB cells. On the other hand 4a was active against Leishmania and it diminished NO production of BCG-induced J774A.1 cells.
