UNC1062 is a highly selective tyrosine kinase inhibitor that specifically targets MERTK. This compound effectively suppresses MERTK-mediated downstream signaling, induces apoptosis in cell cultures, reduces colony formation in soft agar, and inhibits invasion of melanoma cells. Notably, UNC1062 demonstrates potent inhibition of MERTK kinase activity, with an IC50 of 1.1 nM and a Morrison Ki of 0.33 nM. It also displays specificity within the TAM family, exhibiting IC50 values of 60 nM for TYRO3 and 85 nM for AXL [1].
