ABD957 is a potent and selective covalent inhibitor of the ABHD17 family of depalmitoylases, with an IC50 of 0.21 µM for ABHD17B. ABD957 can block N-Ras signaling and the growth of NRAS-mutant AML cells[1].
ABD957 (500 nM; pretreated for 1 h) attenuates N-Ras depalmitoylation in AML cells[1].ABD957 (0.11 nM-10 μM; 72 h) blocks the signaling and proliferation of NRAS-mutant leukemia cells[1].

ABHD17 regulation of plasma membrane palmitoylation and N-Ras-dependent cancer growth
Nat Chem Biol 2021 Aug;17(8):856-864.PMID:33927411DOI:PMC8900659
Multiple Ras proteins, including N-Ras, depend on a palmitoylation/depalmitoylation cycle to regulate their subcellular trafficking and oncogenicity. General lipase inhibitors such as Palmostatin M (Palm M) block N-Ras depalmitoylation, but lack specificity and target several enzymes displaying depalmitoylase activity. Here, we describe ABD957, a potent and selective covalent inhibitor of the ABHD17 family of depalmitoylases, and show that this compound impairs N-Ras depalmitoylation in human acute myeloid leukemia (AML) cells. ABD957 produced partial effects on N-Ras palmitoylation compared with Palm M, but was much more selective across the proteome, reflecting a plasma membrane-delineated action on dynamically palmitoylated proteins. Finally, ABD957 impaired N-Ras signaling and the growth of NRAS-mutant AML cells in a manner that synergizes with MAP kinase kinase (MEK) inhibition. Our findings uncover a surprisingly restricted role for ABHD17 enzymes as regulators of the N-Ras palmitoylation cycle and suggest that ABHD17 inhibitors may have value as targeted therapies for NRAS-mutant cancers.
