Subacute Toxicity of a Purine Nucleoside Phosphorylase Inhibitor in Rats

Toxicological Sciences, 1995
Rats received daily oral doses of 15, 50, 150, or 200 mg/kg CI-1000 for 4 weeks. Doses were selected based on findings from a 2-week range-finding study where doses of 250 and 500 mg/kg resulted in mortality. In the 4-week study, females given 200 mg/kg were sacrificed during Week 2 due to poor condition. Serum creatinine and urea nitrogen increased 2-

Purine Nucleoside Phosphorylase of Bovine Liver Mitochondria

1991
Purine nucleoside phosphorylase (PNPase, purine nucleoside: orthophosphate ribosyltransferase E.C. 2.4.2.1) in mammals reversibly catalyzes the phosphorolysis of the purine ribonucleosides (deoxy)inosine and (deoxy)guanosine to (deoxy)ribose-l-phosphate and the respective base.

Synthesis and Turnover of Purine Nucleoside Phosphorylase in Human Lymphocytes

1986
The inherited deficiency of purine nucleoside Phosphorylase results in severe T cell immunodeficiency disease1. We have studied the synthesis of purine nucleoside Phosphorylase during phytohumagglutinin induced T cell transformation and have examined the turnover of purine nucleoside Phosphorylase in the human lymphoblast WI-L2.
