Dasatinib-d8 is intended for use as an internal standard for the quantification of dasatinib by GC- or LC-MS. Dasatinib is a potent inhibitor of the non-receptor tyrosine kinases Abl and Src as well as other members of the Src family.1,2 It is effective at sub-nanomolar concentrations, inhibiting Src, Abl, and Lck with IC50 values of 0.05, 0.5, and 0.4 nM, respectively.1,3,4 At nanomolar concentrations, dasatinib also blocks the activity of several other receptor and non-receptor tyrosine kinases, plus drug-resistant mutants.3,4 Because of these activities, dasatinib has potential therapeutic value in diseases characterized by elevated levels of these kinases, including some forms of cancer and fibrotic disease.1,5,6,7
