Description

General description

A cell-permeable, bioactive, non-toxic quinoline based compound that acts as a highly potent, ATP-non-competitive, tight-binding type II TAM (Tyro3, Axl, and Mer) kinase inhibitor (IC₅₀ = 8, 29, and 5 nM, respectively for Tyro3, Axl, and Mer). Occupies both the ATP binding cleft and an adjacent hydrophobic pocket. Also displays inhibitory activity against Met, Aurora B, Lck, and Src, but only at relatively higher concentration (IC₅₀ = 35, 36, 51, and 338 nM, respectively). Displays modest selectivity over 39 other protein kinases (at ~1 µM). Reduces the proliferation of selected cancer lines (~ 15 µM). By inhibiting TAM receptors, it enhances anti-metastatic activity of natural killer (NK) cells via TAMR/E3 ligase (Cbl-b; casitas B-lineage lymphoma-b) pathway modulation. Reduces the number and size of 4T1 micro metastases in the liver of an orthotopic murine model of metastatic breast cancer without apparently affecting the primary mammary tumor. Also shown to reduce metastatic spreading of B16F10 melanomas, an effect that is abolished upon NK1.1 depletion.
