Abstract
Metabolically labile prodrugs can experience stark differences in catabolism incurred by the chosen route of administration. This is especially true for phosph(on)ate prodrugs, in which successive promoiety removal transforms a lipophilic molecule into increasingly polar compounds. We previously described a phosphonate inhibitor of enolase (HEX) and its bis-pivaloyloxymethyl ester prodrug (POMHEX) capable of eliciting strong tumor regression in a murine model of enolase 1 (ENO1)-deleted glioblastoma following parenteral administration. Here, we characterize the pharmacokinetics and pharmacodynamics of these enolase inhibitors in vitro and in vivo after oral and parenteral administration. In support of the historical function of lipophilic prodrugs, the bis-POM prodrug significantly improves cell permeability of and rapid hydrolysis to the parent phosphonate, resulting in rapid intracellular loading of peripheral blood mononuclear cells in vitro and in vivo. We observe the influence of intracellular trapping in vivo on divergent pharmacokinetic profiles of POMHEX and its metabolites after oral and parenteral administration. This is a clear demonstration of the tissue reservoir effect hypothesized to explain phosph(on)ate prodrug pharmacokinetics but has heretofore not been explicitly demonstrated.

Abstract
Cancers harboring homozygous deletion of the glycolytic enzyme enolase 1 (ENO1) are selectively vulnerable to inhibition of the paralogous isoform, enolase 2 (ENO2). A previous work described the sustained tumor regression activities of a substrate-competitive phosphonate inhibitor of ENO2, 1-hydroxy-2-oxopiperidin-3-yl phosphonate (HEX) (5), and its bis-pivaloyoxymethyl prodrug, POMHEX (6), in an ENO1-deleted intracranial orthotopic xenograft model of glioblastoma [Nature Metabolism 2020, 2, 1423-1426]. Due to poor pharmacokinetics of bis-ester prodrugs, this study was undertaken to identify potential non-esterase prodrugs for further development. Whereas phosphonoamidate esters were efficiently bioactivated in ENO1-deleted glioma cells, McGuigan prodrugs were not. Other strategies, including cycloSal and lipid prodrugs of 5, exhibited low micromolar IC50 values in ENO1-deleted glioma cells and improved stability in human serum over 6. The activity of select prodrugs was also probed using the NCI-60 cell line screen, supporting its use to examine the relationship between prodrugs and cell line-dependent bioactivation.
