Abstract:
:Allopurinol and allopurinol ribonucleoside tested in vitro and in vivo for activity against Leishmania donovani. Activity in vitro was low against the amastigote form of this parasite with ED50 values of the order of 54 and 96 microM and 86 and 213 microM respectively for the two compounds. In vivo inhibition of up to 47% was achieved with allopurinol ribonucleoside given in the drinking water. However, low blood levels were found in the mouse relative to those in man. Low in vivo activity was also seen with allopurinol ribonucleoside against L. major and other species of Leishmania causing cutaneous lesions. The metabolism of allopurinol ribonucleoside in aldehyde oxidase deficient mice (inbred strains DBA/1, DBA/2) resembled that of man, but the antileishmanial activity remained low. Other compounds, formycin B, sinefungin and the lepidine WR6026 were highly active against mice infected with L. donovani or L. major.
