Usage

Chemical composition

A modified form of the nucleoside adenosine, consisting of a purine base (adenine) attached to a ribose sugar molecule, with two amino groups attached to the purine ring.

Potential applications

Studied for its potential as an antiviral agent, particularly in inhibiting the replication of RNA viruses, and as a therapeutic agent for certain genetic disorders.

Role in RNA research

Used as a probe in studies of RNA structure and function, and investigated for its role in RNA modification.

Synthesis of sugar-modified 2,6-diaminopurine and guanine nucleosides from guanosine via transformations of 2-aminoadenosine and enzymatic deamination with adenosine deaminase

Treatment of 2,6-diaminopurine riboside (2-aminoadenosine) with α- acetoxyisobutyryl bromide in acetonitrile gave mixtures of the trans 2',3'- bromohydrin acetates 2. Treatment of 2 with zinc-copper couple effected reductive elimination, and deprotection gave 2,6-diamino-9-(2,3-dideoxy-β- D-erythro-pent-2-enofuranosyl)purine (3a). Treatment of 2 with Dowex 1 x 2 (OH-) resin in methanol gave the 2',3-anhydro derivative 4. Stannyl radical- mediated hydrogenolysis of 2 and deprotection gave the 2'-deoxy 6a and 3'- deoxy 7a nucleosides. Treatment of the 3',5'-O-(tetraisopropyldisiloxanyl) derivative (5a) with trifluoromethanesulfonyl chloride - 4- (dimethylamino)pyridine gave 2'-triflate 5c. Displacement with lithium azide -dimethylformamide and deprotection gave the arabino 2'-azido derivative 8a, which was reduced to give 2,6-diamino-9 (2-amino-2-deoxy-β-D- arabinofuranosyl)purine (8b). Sugar-modified 2,6-diaminopurine nucleosides were treated with adenosine deaminase to give the corresponding guanine analogues.
