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.
