c kit in 5 1

Cediranib (AZD2171) (AZD2171) is a highly potent (IC50 < 1 nmol L) ATP-competitive inhibitor of recombinant KDR tyrosine kinase in vitro, also inhibits Flt1 4 (IC50: 5 nM ≤3 nM), similar activity against PDGFRβ and c-Kit, selective more for VEGFR than PDGFR-α (36-fold), CSF-1R (110-fold), and Flt3 (1000-fold) in HUVEC cells.

AMG-25 (c-Kit-IN-5-1) is a selective and potent c-Kit inhibitor that inhibits c-Kit, KDR, p38, Lck, and Src, and can be used in the study of mast cell-associated fibrosis.

Imatinib Impurity E is a specific impurity found in Imatinib, an orally available inhibitor of multiple tyrosine kinases, including BCR ABL, v-Abl, PDGFR, and c-kit. Imatinib (STI571) operates by semi-competitively inhibiting enzyme activity; it binds adjacent to the ATP binding site, inducing a closed or self-inhibited conformation [1] [2] [3] [4]. Additionally, Imatinib acts as an inhibitor against SARS-CoV and MERS-CoV [5].
