title: "Lock-in" modified cyclosal nucleotides--the second generation of cyclosal prodrugs.
abstract: A new generation of cycloSal-pronucleotides is presented. CycloSal-d4TMPs have been modified by introduction of an esterase-cleavable site in order to trap them inside cells. Hydrolysis studies in different media (PBS, CEM/0- and liver extracts) and anti-HIV evaluation of separated diastereomers revealed unexpected differences between the isomers.
