R428,1037624-75-1,IC-0203549
R428, as a Axl inhibitor, blocks Axl autophosphorylation on its C-terminal docking site, Tyr821, at nanomolar concentrations[1]. In vitro, R428 inhibited growth of H1299, a human non-small cell lung carcinoma cell line that had constitutively activated Axl, in a dose-dependent manner with an IC50 of approximately 4 µM[1]. In CE81T cells, the IC50 value of R428 was 1.98 µM when treated for 72 h[2]. In vitro, TNBC cells were treated with 0.5, 1 or 2 µM R428 for 30 min, 1-, 2- and 4-h disrupted the polarized localization of the Golgi apparatus towards the leading edge in migratory cells[3]. In vivo, rats were administrated 100 mg/kg body weight (p.o.) R428 that shown more severe RV hypertrophy, augmented right ventricular systolic pressure (RVSP), impaired cardiac output and worsened tricuspid annular plane systolic excursion, and a significantly increased total pulmonary vascular resistance index[4]. In vivo efficacy test it shown that R428 has a long plasma half-life (13 hours at 75 mg/kg), and distributes effectively to tissue[5]. In vivo, mice (8 weeks of age) were treated with 125 mg/kg R428 orally significantly reduced number of CD4+ T cells in the kidney compared to the T cell numbers in the kidney of nephritic B6 mice[6].
