A new synthesis of 6-amino-1-hydroxyethoxymethyl-4(5H)-oxopyrazolo[3,4-d] pyrimidine ( 4) has been mentioned. Compound 4 exhibited inhibition of amastigotes of Leishmania donovani to the extent of 89% at 30 mu g/mL, whereas iso-guanine analogue 5 had the inhibition only to the extent of 52.8% at 100 mu g/mL in vitro. In hamster model the maximum inhibitory response for compound 4 against amastigotes multiplication was observed to be 94% at 50 mg/kg single dose for 5 consecutive days.
