Synthesis and antileishmanial activity of some 1- or 2-(dihydroxyalkyl) and 3-(dihydroxyalkoxy)pyrazolo [3,4-d] pyrimidines.

ABSTRACT

Several new derivatives of 4-amino-, 4,6-diamino- and 4-hydrazino-[3,4-d]pyrimidine dihydroxyalkyl substituted in the 1 or 2 positions, or dihydroxyalkoxy substituted in the 3 position have been synthesized. Some of these compounds were evaluated for their activity against Leishmania infantum in mice. The highest degree of antileishmanial activity was displayed by the 4-amino-1-(dihydroxyalkyl) derivatives which yielded parasite inhibition values nearly comparable with that of glucantime in a standard 5-day test.
