Physical and Chemical Properties | Bioactive Bemcentinib (R428, BGB324) is an Axl inhibitor with IC50 of 14 nM. The selectivity for Axl is more than 100 times higher than for Abl. The selectivity of Axl is also higher than that of Mer and Tyro3 (50 to 100 times higher) and InsR, EGFR, HER2, and PDGFRβ (100 times higher). |
Use | Use R428 is an AXL tyrosine kinase inhibitor and is considered an anticancer drug. |
In vitro study | R428 blocks the catalytic and cancer-promoting activity of Axl. Nanomolar R428 inhibits Axl activity and blocks Axl-dependent processes including Akt phosphorylation, breast cancer cell invasion, and pro-inflammatory cytokine production. A recent study showed that the Axl inhibitor R428 on primary CLL B cells after 24 hours of treatment, the average IC50 is about 2.0 μm, while the normal B cells under similar conditions, T cells and natural killer cells (NK) there was no significant cell death at the concentration of R428 (2.5 μm). |
In vivo study | Pharmacological studies have shown that oral R428 treatment can reduce the expression of macrophage colony stimulating factor and transcriptional regulator Snail of epithelial mesenchymal transition in tumor, which is dose dependent. R428 inhibits angiogenesis in corneal microcapsules and tumor models, supporting a previous study. In MDA-MB-231 intracardiac and 4T1 orthotopic breast cancer metastasis mouse models, R428 treatment reduced the metastatic burden of cancer cells and prolonged survival (median survival greater than 80 days compared to 52 days in the control group, P<0.05). |
