eCF506-d5 

eCF506-d₅ is deuterated labeled eCF506 (HY-112096). 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.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
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^[2].

eCF506 shows a moderate oral bioavailability (25.3%). A significant reduction of phospho-SRC^Y416 is observed in the xenograft sections from mice treated with eCF506 relative to the untreated animal controls^[2].
