2'-Deoxy-N7-methylguanosine is a hydrogenolysis product of guanosine. It can be synthesized in four steps from glycosyl chloride, glycosylamine, and methyl iodide. The catalytic hydrogenolysis of 2'-deoxy-N7-methylguanosine with Raney Ni gives the corresponding 6-amino derivative. Hydrolysis of this amino group converts it to a nucleoside. This nucleoside has been shown to hydrolyze with half-life of about 1 hour at pH 8.5 and 37°C. The hydrolysis of purines by 2'-deoxy-N7-methylguanosine is inhibited by adenosine analogues like 2',3'-dideoxyadenosine and 3',4'-dideoxyadenosine.
