SMU-037
SMU-037 is an orally active and selective ROS1 inhibitor that demonstrates potent activity (IC₅₀ = 6.8 nM) and possesses the ability to penetrate the blood-brain barrier. SMU-037 shows ~25-fold selectivity over ALK, and superior sensitivity against the G2032R mutation. SMU-037 attenuates phosphorylation of ROS1 and downstream MAPK-ERK signaling pathway, leading to cell cycle arrest and apoptosis. SMU-037 effectively suppresses tumor progression in both xenograft and intracranial mouse models. SMU-037 can be used for non-small cell lung cancer (NSCLC) research.

Activité biologique
SMU-037 (compound 9y) exhibits robust activity against A549 (IC50 = 0.9 μM), HCC-78 (IC50 = 1.1 μM) and NCI-H3122 cells (IC50 = 1.1 μM), and inhibits Ba/F3 ROS1G2032R and Ba/F3 ROS1L2026R cells with IC50 values of 8.9 and 32.0 nM[1].
SMU-037 (0.001-3 μM, 8 h) attenuates phosphorylation of ROS1 and the key downstream MAPK-ERK signaling pathway in a dose-dependent manner in multiple Ba/F3 and A549 cells[1].
SMU-037 (0-100 nM, 48 h) arrests cell cycle (G0/G1 phase in ROS1WT cells and G2/M phase in ROS1G2032R cells) and induces apoptosis in both Ba/F3-ROS1WT and Ba/F3-ROS1G2032R cells[1].
