Compound C28 is an orally active, potent, ATP-competitive lemur tyrosine kinase 3 (LMTK3) inhibitor with additional inhibitory potency against only 4 other kinases among a panel of 140 (IC50 = 67 nM/LMTK3, 5 nM/CLK, 6 nM/DYRK1α, 48 nM/HIPK2, 41 nM/IRAK4). LMTK3 promotes proteasome-mediated LMTK3 degradation and decreases proliferation of cancer cultures (NCI-60 panel IC50 <10 μM) and displays antitumor efficacy in xenograft and transgenic breast cancer mouse models in vivo (10 mg/mL via dialy p.o.).
Orally active, potent, ATP-competitive lemur tyrosine kinase 3 (LMTK3), CLK, DYRK1α, HIPK2 inhibitor with anticancer efficacy in cultures and in vivo.
