UNC2025 是高效的、具有口服活性的、ATP 竞争性的Mer/FLT3双抑制剂，IC50值分别为 0.74 nM 和 0.8 nM。它对MERTK 的选择性比 Axl 高 45 倍(IC50:122 nM;Ki:13.3 nM)。它具有良好的 PK 特性，可用于研究急性白血病。

UNC-2025（ IC50 of 0.74 nM and 0.8 nM） is a potent and orally bioavailable dual MER/FLT3 inhibitor. UNC-2025 is about 20-fold selectivity higher than Axl and Tyro3.

In 697 B-ALL cells, UNC-2025 potently inhibits Mer phosphorylation with IC50 of 2.7 nM. In A549 NSCLC and Molm-14 AML cell lines, UNC-2025 causes significant inhibition of colony formation dependent on Mer8 and Flt3. [1] In H2228 and H1299 cell lines, UNC-2025 inhibits MERTK oncogenic signaling downstream, such as basal and stimulated pAKT and pERK1/2. In four NSCLC cell lines, UNC-2025 also induces apoptotic cell death, and decreases colony formation. [2]

In mice bearing 697 acute leukemia tumors, UNC-2025 (3 mg/kg, p.o.) shows good solubility and DMPK properties, and results in effective target inhibition. [1] In mice bearing H2228 or A549 tumors, UNC-2025 (50 mg/kg, p.o.) inhibits tumor growth. [2]
