The cellular delivery of nucleotides through various pronucleotide strategies has expanded the utility of nucleosides as a therapeutic class. Although highly successful, the highly popular ProTide system relies on a four-step enzymatic and chemical process to liberate the corresponding monophosphate. To broaden the scope and reduce the number of steps required for monophosphate release, we have developed a strategy that depends on initial chemical activation by a sulfur atom of a methylthioalkyl protecting group, followed by enzymatic hydrolysis of the resulting phosphoramidate monoester. We have employed this ProTide strategy for intracellular delivery of a nucleotide antagonist of eIF4E in mantle cell lymphoma (MCL) cells. Furthermore, we demonstrated that chemical inhibition of cap-dependent translation results in suppression of c-Myc expression, increased p27 expression, and enhanced chemosensitization to doxorubicin, dexamethasone, and ibrutinib. In addition, the new ProTide strategy was shown to enhance oral bioavailability of the corresponding monoester phosphoramidate.
