title: Novel nucleotide analogues as potential substrates for TMPK, a key enzyme in the metabolism of AZT.
abstract: Novel cyclic and acyclic analogues of dTMP and AZTMP were synthesized from the corresponding cycloSal-phosphotriesters. This method yielded the nucleotides in good yields with a simple work-up. Investigation of the substrate properties of the modified nucleotides towards TmpK showed, that they are very poor substrates for this key enzyme in the bioactivation of AZT.
