[CAS NO. 1239875-86-5]  SGI-7079

SGI-7079 exhibits a Ki = 5.7 nM for AXL and inhibits Gas6 ligand-induced tyrosine phosphorylation of human AXL expressed in HEK293T cells (EC50 = 100 nM). It inhibits TAM family members MER and Tyro3 similarly as AXL, and shows potent, low nM inhibition of Syk, Flt1, Flt3, Jak2, TrkA, TrkB, PDGFRβ and Ret kinases. Mesenchymal cells express increased levels of the receptor tyrosine kinase Axl and show a trend toward greater sensitivity to the Axl inhibitor SGI-7079.
