Quizartinib (AC220) is an inhibitor of FLT3 (Kd: 1.6 nM) and demonstrates high selectivity for FLT3 when tested against a panel of 227 additional kinases.

Gilteritinib (ASP2215) is a potent inhibitor of FMS-related tyrosine kinase 3 (FLT3) and AXL tyrosine kinase receptors (IC50 = 0.29 nM and <1 nM, respectively). In preclinical studies, gilteritinib demonstrated strong antileukemic and antitumor effects. Gilteritinib is currently in several Phase 3 clinical trials for acute myeloid leukemia.

Fostamatinib (R788)(IC50 of 41 nM), which is a prodrug of the active metabolite R406, is a Syk inhibitor. It does not work on Lyn.

Sotuletinib (BLZ945) is an orally active, effective and specific CSF-1R inhibitor (IC50: 1 nM), >1000-fold selective against its closest receptor tyrosine kinase homologs.

Ripretinib (DCC-2618) is an orally bioavailable inhibitor of (KIT) and (PDGFRA).

c-Fms-IN-2 is an inhibitor of c-FMS kinase (IC50 = 24 nM).

AKN-028 is an orally active and potent FLT3 tyrosine kinase inhibitor ( IC 50 = 6 nM). AKN-028 causes dose-dependent inhibition of FLT3 autophosphorylation.

c-Fms-IN-13 (compound 14) is a potent FMS kinase inhibitor (IC50 = 17 nM) and serves as an anti-inflammatory agent.

4SC-203 is a multi-kinase inhibitor with potential anti-tumor activity. 4SC-203 exhibits unique selectivity for Flt3, Flt3 mutants, Axl, Alk, Fak, VEGF-R2, and Trk receptors in the low nM range.

Sorafenib tosylate (Bay 43-9006) is a potent multikinase inhibitor (IC50s: 6 20 22 nM for Raf-1 VEGFR-3 B-Raf).

Cabozantinib (XL184) is a multi-targeted tyrosine kinase receptor inhibitor that inhibits VEGFR2, c-Met, Kit, Axl, and Flt3 (IC50=0.035/1.3/4.6/7/11.3 nM). Cabozantinib exhibits both antitumor and antiangiogenic activity.

Crenolanib (ARO 002) is an orally bioavailable type III tyrosine kinases inhibitor of PDGFRα β and FLT3 (IC50s: 11, 3.2, and 4 nM).

Merestinib (LY2801653) is an orally available, small molecule inhibitor of the proto-oncogene c-Met (Ki: 2 nM) with potential antineoplastic activity. Merestinib electively binds to c-Met, thereby inhibiting c-Met phosphorylation and disrupting c-Met signal transduction pathways. This may induce cell death in tumor cells overexpressing c-Met protein or expressing the constitutively activated c-Met protein.

Sitravatinib (MGCD516) is an inhibitor targeting multiple RTKs involved in driving sarcoma cell growth, including c-Met, c-Kit, PDGFRα β, PDGFR, and Axl.

Pacritinib (SB1518) (SB1518) is an effective and specific inhibitor of JAK2 and FLT3 (IC50: 23 22 nM, in cell-free assays).

FLT3-IN-10 (2-Oxazolamine, 5-(4-fluorophenyl)-N-phenyl-) (compound 7c) is a potent inhibitor of FMS-like tyrosine kinase 3 (FLT3). FLT3-IN-10 shows the potential for the treatment of FLT3-mutated acute myeloid leukemia (AML).

c-Fms-IN-10, a derivative of thieno [3,2-d] pyrimidine, is a kinase inhibitor of FMS (Colony-stimulating factor-1 receptor, CSF-1R; IC50: 2 nM) with anti-tumor activity.

c-Fms-IN-9 is a c-FMS inhibitor that inhibits unphosphorylated c-FMS kinase (uFMS) and uKIT with IC50 values of <0.01 μM and 0.1-1 μM, respectively.

FLT3-IN-3 is an effective FLT3 inhibitor, and the IC50s of FLT3 WT and FLT3 D835Y are 13 and 8 nM, respectively.
