General description

S-(4-Nitrobenzyl)-6-thioinosine (NBTI) belongs to the family of S6-substituted 6-thiopurine nucleosides, which regulate nucleoside transport mechanisms in animals. It acts as a ligand of adenosine transporter. Binding sites for NBTI is located on brain capillaries. It functions as a covalent photoaffinity probe for nucleoside transport.

Biochem/physiol Actions

Inhibitor of equilibrative nucleoside transporters (ENTs), particularly adenosine transporters, in central nervous system and vascular smooth muscle.
Potent adenosine uptake inhibitor
