Discoidin Domain Receptor (DDR)

DDR inhibitor is a potent discidin domain receptor (DDR) inhibitor. The IC50 of DDR2 is 3.3 nM, and DDR1 has 53% inhibition at 1.5 nM.

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

DDR1-IN-1 is an effective and specific DDR1 receptor tyrosine kinase inhibitor (IC50: 105 nM), about 3-fold selectivity over DDR2.

DDR-TRK-1, a selective discoid domain receptor 1 (DDR1) inhibitor, exhibits an IC50 value of 9.4 nM and also inhibits the TRK family.

MitoBloCK-6 is an effective inhibitor of Erv1 ALR with IC50 values of 900 nM and 700 nM, respectively. Additionally, MitoBloCK-6 inhibits Erv2 (IC50=1.4 μM). It induces apoptosis in hESCs by promoting the release of cytochrome c.

WRG-28 is a potent and selective, allosteric discoidin domain receptor 2 (ddr2) inhibitor(IC50 : 230 nM)

FGFR1 DDR2 inhibitor 1 is an inhibitor of discoidin domain receptor 2 (DDR2) and fibroblast growth factor receptor 1 (FGFR1), with IC50 values of 31.1 nM, 108.4 nM, and 3.2 nM for FGFR1, KG-1, and DDR2, respectively.

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.

DDR1-IN-2 (DDR1 inhibitor 7rh) (DDR1 inhibitor 7rh) is a potent, selective, ATP-competitive Discoidin domain receptor 1 (DDR1) inhibitor (IC50: 6.8 nM in cell-free kinase assays).

LCB 03-0110 (3-(2-(3-(Morpholinomethyl)phenyl)thieno[3,2-b]pyridin-7-ylamino)phenol) is a potent inhibitor of discoidin domain receptor family tyrosine kinases and strongly inhibits several tyrosine kinases, including the c-Src family, spleen tyrosine kinase, Bruton's tyrosine kinase, and vascular endothelial growth factor receptor 2, which are important for immune cell signaling and inflammatory reactions.

DDR1-IN-4 (Compound 2.45) is a highly potent inhibitor that selectively targets Discoidin Domain Receptor 1 (DDR1) autophosphorylation, demonstrating exceptional efficacy with IC50 values of 29 nM for DDR1 and 1.9 μM for DDR2.

VU6015929 is an inhibitor of active dual discoidin domain receptor 1 2 (DDR1 2)( IC50s of 4.67 nM and 7.39 nM, respectively).
