flt3/stk1

4SC-203 是一种具有潜在的抗肿瘤活性的多激酶抑制剂。4SC-203在低 nM 范围内对 Flt3、Flt3 突变体、Axl、Alk、Fak、VEGF-R2 和 Trk 受体表现出独特的选择性。

Quizartinib, also know as AC220 and AC010220, is an orally available FLT3 STK1 inhibitor with potential antineoplastic activity. Class III receptor tyrosine kinase inhibitor AC220 selectively inhibits class III receptor tyrosine kinases, including FMS-related tyrosine kinase 3 (FLT3 STK1), colony-stimulating factor 1 receptor (CSF1R FMS), stem cell factor receptor (SCFR KIT), and platelet derived growth factor receptors (PDGFRs), resulting in inhibition of ligand-independent leukemic cell proliferation and apoptosis. Mutations in FLT3, resulting in constitutive activation, are the most frequent genetic alterations in acute myeloid leukemia (AML) and occur in approximately one-third of AML cases.
