In the beginning, GNE-1858 is a potent and ATP-competitive HPK1 inhibitor. 05 µΜ) kinase activities. 6 MG132 is a proteasome inhibitor, which blocks the degradation of proteins. Biophysical measurements show formation of dimer in. Hematopoietic progenitor kinase (HPK1) is a regulator of cellular response to stress, proliferation, and apoptosis. However, a significant challenge remains to identify a small molecule inhibitor of HPK1 with sufficient potency, selectivity, and other drug-like properties suitable for proof-of-concept studies. Studies using genetic disruption of HPK1 function show enhanced T-cell signaling, cytokine production, and in vivo tumor growth inhibition.
