Didanosine CAS 69655-05-6

Didanosine(Videx) is a reverse transcriptase inhibitor with an IC50 of 0.49 μM.Target: NRTIs; HIVDidanosine is a dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by a hydrogen. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. Didanosine is a potent inhibitor of HIV replication, acting as a chain-terminator of viral DNA by binding to reverse transcriptase. Didanosin
A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by a hydrogen. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. Didanosine is a potent inhibitor of HIV replication, acting as a chain-terminator of viral DNA by binding to reverse transcriptase; ddI is then metabolized to dideoxyadenosine triphosphate, its putative active metabolite.
Didanosine is an orally active purine dideoxynucleoside analog indicated for adult and pediatric patients with advanced HIV infection who are either intolerant or significantly deteriorated on zidovudine. It appears to increase CD4 cell counts and decrease p24 antigen levels.Major adverse effects are pancreatitis, peripheral neuropathy and diarrhea.Unlike zidovudine, didanosine exhibits insignificant bone marrow suppression.
White Powder
ChEBI: A purine 2',3'-dideoxyribonucleoside that is inosine in which the hydroxy groups at both the 2' and the 3' positions on the sugar moiety have been replaced by hydrogen.
