In vitro
In vitro	R428 blocks the catalytic and procancerous activities of Axl. R428 inhibits Axl with low nanomolar activity and blocks Axl-dependent events, including Akt phosphorylation, breast cancer cell invasion, and proinflammatory cytokine production. ^[1] In a recent study, the Axl inhibitor R428 shows a mean IC50 dose of ∼ 2.0μM for the primary CLL B cells after 24 hours of treatment and normal B-, T-, and natural killer (NK) cells show no significant amount of cell death at this dose of R428 (2.5 μM) under similar experimental conditions. ^[2]

In Vivo
In vivo	Pharmacologic investigations reveal favorable exposure after oral administration such that R428-treated tumors display a dose-dependent reduction in expression of the cytokine granulocyte macrophage colony-stimulating factor and the epithelial-mesenchymal transition transcriptional regulator Snail. In support of an earlier study, R428 inhibits angiogenesis in corneal micropocket and tumor models. R428 administration reduces metastatic burden and extends survival in MDA-MB-231 intracardiac and 4T1 orthotopic (median survival, >80 days compared with 52 days; P < 0.05) mouse models of breast cancer metastasis. ^[1]
