THE ESTIMATION OF HYPOXANTHINE [PDF]

Journal of Biological Chemistry, 1942
In a previous paper there was described a procedure for the isolation of the purines in a form suitable for the quantitative determination of the individual substances (1). A later publication reported a method for the separation of adenine and hypoxanthine and the determination of the adenine by precipitation of adenine picrate and titration of the ...

Didanosine determination in diluted alkaline electrolyte by adsorptive stripping voltammetry at the mercury film electrode [PDF]

Journal of Electrochemical Science and Engineering, 2012
A stripping method for the determination of didanosine at the submicromolar concentration levels is described. The method is based on controlled adsorptive accumulation of didanosine at thin-film mercury electrode followed by a linear cyclic scan ...

The ATM Kinase Inhibitor AZD0156 Is a Potent Inhibitor of Plasmodium Phosphatidylinositol 4‐Kinase (PI4Kβ) and Is an Attractive Candidate for Medicinal Chemistry Optimization Against Malaria

Angewandte Chemie, EarlyView.
AZD0156, an ATM kinase inhibitor in clinical development, shows promising multistage antiplasmodial activity by targeting Plasmodium falciparum phosphatidylinositol 4‐kinase (PfPI4Kβ). With an improved specificity profile relative to other PfPI4Kβ inhibitors and moderate efficacy in a P.

Hypoxanthine as a Measurement of Hypoxia [PDF]

Pediatric Research, 1975
The hypoxanthine concentration in plasma was found to be a sensitive parameter of hypoxia of the fetus and the newborn infant. The plasma level of hypoxanthine in the umbilical cord in 29 newborn infants with normal delivery varied between 0 and 11.0 mumol/liter with a mean of 5.8 mumol/liter, SD 3.0 mumol/liter.

Hypoxanthine Induces Muscular ATP Depletion and Fatigue via UCP2

Frontiers in Physiology, 2021
Hypoxanthine (Hx), an intermediate metabolite of the purine metabolism pathway which is dramatically increased in blood and skeletal muscle during muscle contraction and metabolism, is characterized as a marker of exercise exhaustion.
