Metabolism of pyrazolo(3,4-d)pyrimidines in Leishmania braziliensis and Leishmania donovani. Allopurinol, oxipurinol, and 4-aminopyrazolo(3,4-d)pyrimidine.

Leishmania donovani and Leishmania braziliensis grown in culture formed millimolar concentrations of allopurinol ribonucleoside 5'-monophosphate from [6-14C]allopurinol. In addition, allopurinol 1-ribonucleoside, oxipurinol riboside 5'-monophosphate, and three new metabolites of allopurinol, namely, 4-aminopyrazolo(3,4-d)pyrimidine ribonucleoside 5'-monophosphate and the corresponding di- and t...

Metabolism of Pyrazolo(3,4-d)pyrimidines in Leishmania braziliensis and Leishmania donovani

Leishmania donovani and Leishmania braziliensis grown in culture formed millimolar concentrations of allopurinol ribonucleoside 5’-monophosphate from [6“C]allopurinol. In addition, allopurinol l-ribonucleoside, oxipurinol riboside 5’-monophosphate, and three new metabolites of allopurinol, namely, 4-aminopyrazolo(3,4-d)pyrimidine ribonucleoside V-monophosphate and the corresponding diand tripho...

Leishmania braziliensis brazilensis and L. donovani chagasi

This study describes the identification of aqueous-soluble antigens in Leishmania promastigotes immunologically and biochemically closely related to the major surface antigen. Proteins from surface-iodinated L. braziliensis braziliensis and L. donovani chagasì promastigotes, extracted and separated by partitioning in the detergent Triton X-114, were analyzed. Immunoblotting of the extracted pro...

Glycobiology of Leishmania donovani.

Leishmania donovani, the causative organism of visceral leishmaniasis (VL) is one of the deadliest of the entire known Leishmania species. This protozoan parasite displays immense adaptability to survive under extremely harsh conditions. Cell surface glycoconjugates play a pivotal role in parasite virulence and infectivity. This review mainly highlights on the importance of these molecules and ...

Extreme inbreeding in Leishmania braziliensis.

Leishmania species of the subgenus Viannia and especially Leishmania braziliensis are responsible for a large proportion of New World leishmaniasis cases. The reproductive mode of Leishmania species has often been assumed to be predominantly clonal, but remains unsettled. We have investigated the genetic polymorphism at 12 microsatellite loci on 124 human strains of Leishmania braziliensis from...
