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).

Trisubstituted pyrazolopyrimidines as novel angiogenesis inhibitors. [PDF]

open access: yes, 2013
Current inhibitors of angiogenesis comprise either therapeutic antibodies (e.g. bevacicumab binding to VEGF-A) or small molecular inhibitors of receptor tyrosin kinases like e.g. sunitinib, which inhibits PDGFR and VEGFR.
