Preferred Label : dideoxyadenosine;
MeSH definition : 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been replaced by a hydrogen.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. The compound
is an inhibitor of HIV replication, acting as a chain-terminator of viral DNA by binding
to reverse transcriptase. Its principal side effect is nephrotoxicity. In vivo, dideoxyadenosine
is rapidly metabolized to DIDANOSINE (ddI) by enzymatic deamination; ddI is then converted
to dideoxyinosine monophosphate and ultimately to dideoxyadenosine triphosphate, the
putative active metabolite.;
