Bemcentinib

Bemcentinib (R428) is a selective and orally active Axl inhibitor with an IC₅₀ of 14 nM. Bemcentinib retards cancer cell migration and invasion. Bemcentinib exhibits >100-fold selectivity for Axl versus Abl and 50- and >100-fold selectivity over TAM family kinases Mer and Tyro3, respectively, in cells. Bemcentinib blocks tumor spread and prolongs survival in models of metastatic breast cancer^[1][2]. IC50 & Target:IC50: 14 nM (Axl kinase)^[1][2]. In Vitro:Bemcentinib (R428) (2 μM) significantly interferes with mechanisms of migration and invasion of Axlpos melanoma cells at levels comparable to Axl knockdown^[1].
Bemcentinib (R428) synergizes with CDDP to enhance suppression of liver micrometastasis^[2].
Bemcentinib (R428) (50 nM-1 μM) causes a concentration-dependent inhibition of preadipocyte differentiation into mature adipocytes, as evidenced by reduced lipid uptake^[3]. In Vivo:Bemcentinib (R428) (125 mg/kg, p.o.) significantly blocks MDA-MB-231-luc-D3H2LN metastases development in two independent mouse models of breast cancer dissemination, suppresses both tumor angiogenesis and vascular endothelial growth factor (VEGF)-induced corneal neovascularization in vivo^[2].
Bemcentinib (R428) (75 mg/kg/day, 25 mg/kg twice daily, p.o.) makes mice keep on a high-fat diet resulted in significantly reduced weight gain and subcutaneous and gonadal fat mass^[3].
