Here we report the development of an 18F-labeled, activity-based small molecule probe targeting the cancer-associated serine hydrolase NCEH1. We undertook a focused medicinal chemistry campaign to simultaneously preserve potent and specific NCEH1 labeling in live cells and animals, while permitting facile 18F radionuclide incorporation required for PET imaging. The resulting molecule, [18F]JW199, labels active NCEH1 in live cells at nM concentrations and greater than 1,000-fold selectivity relative to other serine hydrolases. [18F]JW199 displays rapid, NCEH1-dependent accumulation in mouse tissues. Finally, we demonstrate that [18F]JW199 labels aggressive cancer tumor cells in vivo, which uncovered localized NCEH1 activity at the leading edge of triple-negative breast cancer tumors, suggesting roles for NCEH1 in tumor aggressiveness and metastasis. A Covalent PET probe: An 18F-labeled, activity-based small molecule probe, [18F]JW199, potently and selectively targets NCEH1 in live cells and displays rapid, NCEH1-dependent accumulation in mouse tissues and tumor xenografts.
