UNC2025 is a potent, ATP-competitive and highly orally active Mer/Flt3 inhibitor with IC50 values of 0.74 nM and 0.8 nM, respectively. UNC2025 is >45-fold selectivity for MERTK relative to Axl (IC50= 122 nM; Ki = 13.3 nM). UNC2025 exhibits an excellent PK properties, and can be used for the research of acute leukemia. UNC2025 is against FLT3, MER, AXL, TRKA, TRKC, QIK, TYRO3, SLK, NuaK1, KIT and Met with IC50 values of 0.35 nM, 0.46 nM, 1.65 nM, 1.67 nM, 4.38 nM, 5.75 nM, 5.83 nM, 6.14 nM, 7.97 nM , 8.18 nM and 364 nM, respectively. UNC2025 (25-300 nM; 1 hour) mediates potent and dose-dependent decreases in MERTK phosphorylation/activation in both cell lines and inhibition of MERTK correlated with decreased phosphorylation of previously reported MERTK-dependent signaling components STAT6, AKT, and ERK1/2.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
