NCIt definition : A purine analogue with potential antineoplastic activity. 8-Azaguanine interferes
with the modification of transfer ribonucleic acid (tRNA) by competing with guanine
for incorporation into tRNA catalyzed by the enzyme tRNA-guanine ribosyltransferase
(tRNA-guanine transglycosylase). Altered guanine modification of tRNA has been implicated
in cellular differentiation and neoplastic transformation. 8-Azaguanine also inhibits
the formation of 43S and 80S initiation complexes, thereby interfering with initiation
of translation and inhibiting protein synthesis. This agent inhibits tumor cell growth
and stimulates cell differentiation. (NCI04);
