didanosine, ddI (drug)
didanosine, ddI (drug) is a Nucleoside reverse transcriptase inhibitor (NRTI) Small molecule drug developed by French National Agency for Research on AIDS and Viral Hepatitis. It is currently in Phase 3 development for HIV-1 infection (as part of combination antiretroviral therapy).
Didanosine is a nucleoside reverse transcriptase inhibitor (NRTI) that blocks HIV reverse transcriptase, preventing the virus from converting its RNA genome into DNA and replicating within host cells.

Mechanism of action
Didanosine is a purine nucleoside analog that is phosphorylated intracellularly to its active form, dideoxyadenosine triphosphate (ddATP). This active metabolite competes with natural deoxyadenosine triphosphate for incorporation into the growing DNA chain during reverse transcription, causing chain termination and inhibiting HIV replication. It was one of the early antiretroviral agents used in HIV treatment.
