Glutathione-Mediated Neuroprotective Effect of Purine Derivatives. [PDF]

open access: yesInt J Mol Sci, 2023
Numerous basic studies have reported on the neuroprotective properties of several purine derivatives such as caffeine and uric acid (UA). Epidemiological studies have also shown the inverse association of appropriate caffeine intake or serum urate levels with neurodegenerative diseases such as Alzheimer disease (AD) and Parkinson’s disease (PD).
