Description

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

5'-S-(2-aminoethyl)-6-N-(4-nitrobenzyl)-5'-thioadenosine (SAENTA), 5'-S-(2-acetamidoethyl)-6-N-[(4-substituted)benzyl]-5'-thioadenosine analogues, 5'-S-[2-(6-aminohexanamido)]ethyl-6-N-(4-nitrobenzyl)-5'-thioadenosine (SAHENTA), and related compounds were synthesized by S(N)Ar displacement of fluoride from 6-fluoropurine intermediates with 4-(substituted)benzylamines. Conjugation of the pendant amino groups of SAENTA and SAHENTA with fluorescein-5-yl isothiocyanate (FITC) gave fluorescent probes that bound
