Intracellular studies of the nucleoside reverse transcriptase inhibitor active metabolites: a review
Rodriguez Orengo J, SantAna J, Febo I, Diaz C, Rodriguez J, Garcia R, et al.
P R Health Sci J
. 2000 Apr;
19(1):19-27.
PMID: 10761201
Nucleoside reverse transcriptase inhibitors (NRTIs) plasma concentrations do not correlate with clinical efficacy or toxicity. These agents need to be phosphorylated to become active against HIV-infection. Thus, the characterization of...
