S-(4-Nitrobenzyl)-6-thioinosine (NBTI, NBMPR) is a small molecule inhibitor of equilibrative nucleoside transporter (ENT) proteins. These transport proteins are described in relation to their sensitivity to S-(4-Nitrobenzyl)-6-thioinosine (NBTI, NBMPR), designated as either es (S-(4-Nitrobenzyl)-6-thioinosine (NBTI, NBMPR)-sensitive) or ei (S-(4-Nitrobenzyl)-6-thioinosine (NBTI, NBMPR)-insensitive). They provide good research tools anticancer, antiviral, cardioprotective, and neuroprotective agents. Inhibition of ENT1 by S-(4-Nitrobenzyl)-6-thioinosine (NBTI, NBMPR) blocks the uptake and transport of adenosine, which affects the regulation of extracellular adenosine levels and the cardiac system signaling associated with adenosine.
