PNP inhibitors selectively kill cancer cells lacking SAMHD1
Molecular & Cellular Oncology, 2020 Purine nucleoside phosphorylase inhibitors (PNP-Is) were developed to ablate transformed lymphocytes. However, only some patients with leukemia benefit from PNP-Is. We provide a molecular explanation: the deoxyribonucleoside triphosphate (dNTP) hydrolase

Thermodynamic reaction control of nucleoside phosphorolysis [PDF]
, 2020 Nucleoside analogs represent a class of important drugs for cancer and antiviral treatments. Nucleoside phosphorylases (NPases) catalyze the phosphorolysis of nucleosides and are widely employed for the synthesis of pentose‐1‐phosphates and nucleoside ...

An Enzymatic Flow-Based Preparative Route to Vidarabine
Molecules, 2020 The bi-enzymatic synthesis of the antiviral drug vidarabine (arabinosyladenine, ara-A), catalyzed by uridine phosphorylase from Clostridium perfringens (CpUP) and a purine nucleoside phosphorylase from Aeromonas hydrophila (AhPNP), was re-designed under ...

Purine nucleoside phosphorylase: A new marker for free oxygen radical injury to the endothelial cell [PDF]
, 1990 The effect of ischemia and reperfusion on purine nucleoside phosphorylase was studied in an isolated perfused rat liver model. This enzyme is localized primarily in the cytoplasm of the endothelial and Kupffer cells; some activity is associated with the ...

Targeting purine metabolism in ovarian cancer
Journal of Ovarian Research, 2022 Purine, an abundant substrate in organisms, is a critical raw material for cell proliferation and an important factor for immune regulation. The purine de novo pathway and salvage pathway are tightly regulated by multiple enzymes, and dysfunction in ...

Purine Nucleoside Phosphorylase Deficiency [PDF]
Arthritis & Rheumatism, 1979 AbstractThe biochemical features of two families with purine nucleoside phosphorylase deficiency are compared. Laboratory studies and an evaluation of kinetic and physical properties of erythrocyte purine nucleoside phosphorylase give evidence that a) the degree of abnormality in uric acid and nucleoside concentrations in plasma and urine reflect the ...
