UNC2541 is a potent and Mer tyrosine kinase (MerTK)-specific inhibitor, binds in the MerTK ATP pocket, with an IC50 of 4.4 nM, more selective over Axl, Tyro3 and Flt3. UNC2541 inhibits phosphorylated MerTK (pMerTK; EC50, 510 nM).IC50 & Target: UNC2541 is a potent and Mer tyrosine kinase (MerTK)-specific inhibitor, binds in the MerTK ATP pocket, with an IC50 of 4.4 nM, more selective over Axl (IC50, 120 nM), Tyro3 (IC50, 220 nM) and Flt3 (IC50, 320 nM).
