| Description | Allopurinol riboside is a metabolite of allopurinol with potency against parasites. Allopurinol riboside competitively inhibits the action of purine nucleoside phosphorylase on inosine with a Ki of 277 μM. |
| In vitro | Allopurinol riboside is effective against parasites including leishmaniasis and American trypanosomiasis. Allopurinol riboside is selectively toxic because it is not metabolized by the corresponding enzymes in humans[1]. Humoral immunity is not suppressed by Allopurinol riboside. Lymphocyte blastogenesis induced by PHA and Con A is significantly suppressed by Allopurinol riboside in a concentration-dependent manner[2]. |
| In vivo | Low levels of Allopurinol riboside in plasma are attributable to incomplete absorption and rapid renal clearance. Probenecid reduces the renal clearance of allopurinol riboside, extends the half-life of allopurinol riboside in plasma, and triples the levels of allopurinol riboside in plasma[3]. Allopurinol riboside peaks in plasma 1.6 hours after administration, has an elimination half-life of 3 h, and has steady-state concentrations in the therapeutic range[4]. |
