6-Methoxypurine-9-β-D-5’(R)-C-methylriboside		Nucleoside Analogs
6-Methoxypurine-9-β-D-5’(R)-C-methylriboside is a hypoxanthine analog. Hypoxanthine is a kind of purine base mainly present in muscle tissue. And it is a metabolite produced by purine oxidase acting on xanthine. Hypoxanthine has typical anti-inflammatory effects and is a potential endogenous poly(ADP-ribose) polymerase (PARP) inhibitor. It is cytoprotective by inhibiting PAPR activity, inhibiting peroxynitrite-induced mitochondrial depolarization and secondary superoxide production. Hypoxanthine can also be used as an indicator of hypoxia .

HY-113273B

Diadenosine pentaphosphate pentaammonium		Nucleotide Analogs Adenine Nucleotide
Diadenosine pentaphosphate pentaammonium is an endogenous vasoactive purine dinucleotide which has been isolated from thrombocytes. Diadenosine polyphosphates (ApnA, n=2–7) have been identified as constituents of secretory vesicles such as in platelets, chromaffin cells, Torpedo synaptic terminals and brain synaptosomes .
