DKM 2-93 is a relatively selective inhibitor of UBA5 with an IC₅₀ of 430 μM.

IC50: 430 μM (UBA5), 90 μM (PaCa2 cells), 30 μM (Panc1 cells)^[1]

Ubiquitin-like modifier activating enzyme 5 (UBA5) is a novel pancreatic cancer therapeutic target. DKM 2-93 impairs pancreatic cancer cell survival through covalently modifying the catalytic cysteine of UBA5, thereby inhibiting its activity as a protein that activates the ubiquitin-like protein UFM1 to UFMylate proteins. DKM 2-93 inhibits PaCa2 and Panc1 cells survival with IC₅₀s of 90 and 30 μM, respectively^[1].

DKM 2-93 daily treatment significantly impairs tumor growth of PaCa2 cells in vivo in tumor xenograft studies in immune-deficient mice without causing any weight loss or overt toxicity^[1].
