Cell experiment: | MDA-MB-231 cells are treated with eCF506 or dasatinib (10 nM), and cell migration compared with untreated cell control (DMSO, 0.1%, v/v) at 6, 12, and 24 h. Cells are imaged and analyzed using an IncuCyte-ZOOM microscope with integrated scratch-wound migration software module[1]. |
Animal experiment: | Mice[1]In vivo PD study is performed in a xenograft model of HCT116 cells in mice. HCT116 cells are injected subcutaneously, and tumors are allowed to grow up to 3-mm in diameter. Subsequently, mice are dosed daily for 3 d with eCF506 (50 mg/kg, in nanopure water) or vehicle (nanopure water) by oral gavage and culled 3 h after the last dose (n=4). Tumors are excised, fixed, and sections labeled for phospho-SRCY416 and stained with hematoxylin[1]. |
产品描述 | eCF506 is a highly potent and orally bioavailable inhibitor of the non-receptor tyrosine kinase Src with an IC50 of less than 0.5 nM. eCF506 induces a very potent antiproliferative effect in both MCF7 and MDA-MB-231 cells. eCF506 inhibits phosphorylation of SRC and FAK at low nanomolar levels, with complete inhibition observed at 100 nM. eCF506 significantly reduces cell motility at 10 nM as early as 6 h into the study, with equivalent efficacy to dasatinib. eCF506 exclusively inhibits SFK, with subnanomolar IC50 values against SRC and YES (IC50=0.5, 2.1 nM). It is important to highlight that eCF506 displays a vast difference in activity (>950-fold difference) between ABL and its primary target SRC[1]. eCF506 shows a moderate oral bioavailability (25.3%). A significant reduction of phospho-SRCY416 is observed in the xenograft sections from mice treated with eCF506 relative to the untreated animal controls[1]. [1]. Fraser C, et al.
