Didanosine (ddI): A Nucleoside Reverse Transcriptase Inhibitor

2',3'-Dideoxyadenosine (ddA) [D3065] and didanosine (ddI) are nucleoside reverse transcriptase inhibitors. ddA is a synthetic nucleoside analogue of the naturally occurring nucleoside 2’-deoxyadenosine in which the 3'-hydroxyl group is replaced by hydrogen. Intracellularly, ddA and ddI are converted by cellular enzymes to the active metabolite, ddA- 5'-triphosphate. The triphosphate inhibits the activity of viral reverse transcriptase both by competing with the natural substrate, 2’-deoxyadenosine-5'-triphosphate, and by its incorporation into viral DNA causing termination of viral DNA chain.
