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-stimulatingfactor 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.
Edicotinib, also known as JNJ-40346527, is a small molecule and orally available inhibitor of colony-stimulatingfactor-1 receptor (CSF1R; FMS) with potential antineoplastic activity. FMS tyrosine kinase inhibitor JNJ-40346527 blocks the receptor-ligand interaction between FMS and its ligand CSF1, thereby preventing autophosphorylation of FMS. As a result, unphosphorylated FMS cannot activate FMS-mediated signaling pathways, thus potentially inhibiting cell proliferation in FMS-overexpressed tumor cells.
c-Fms-IN-10 is the derivative of thieno [3,2-d] pyrimidine, a kinase inhibitor of FMS (Colony-stimulatingfactor-1 receptor, CSF-1R; IC50: 2 nM) with anti-tumor activity.
CSF1R-IN-13 is a powerful CSF1R inhibitor with potential applications in researching cancer diseases [1]. CSF1R, also known as colonystimulatingfactor 1 receptor, is a critical growth factor that regulates various cell types, including bone marrow progenitor cells, monocytes, macrophages, and giants [1]. CSF1R-IN-13 shows promise in furthering our understanding of cancer-related disorders (WO2019134661A1, compound 32) [1].
