Request The Product List ofDiscoidin Domain Receptor (DDR) Discoidin Domain Receptor (DDR)

Discoidin domain receptors (DDRs) are receptor tyrosine kinases with the unique ability among receptor tyrosine kinases to respond to collagen. Several signaling molecules have been implicated in DDR signaling, including Shp-2, Src, and MAPK pathways. DDRs have been reported to induce the expression of various genes including matrix metalloproteinases and bone morphogenetic proteins, but the regulatory mechanisms underlying DDR-induced gene expression remain to be determined. DDRs regulate cell-collagen interactions in normal and pathological conditions and thus are emerging as major sensors of collagen matrices and potential novel therapeutic targets.

DDR1 inhibitor 2.45

2125676-13-1

DDR1 inhibitor 2.45 (Compound 2.45) is a novel potent, selective, bioavailable Discoidin Domain Receptor 1 (DDR1) inhibitor with IC50 of 29 nM, displays 64-fold selectivity over DDR2 in biochemical assays; also possesses excellent kinome selectivity against a kinase panel of 468 kinases; Compound 2.45 inhibits DDR1 phosphorylation (70% inhibition at 1 uM in HT1080 cells overexpressing DDR1) and recruitment of SHC1 in vitro, and modulates phenotype of collagen stimulated renal epithelial cells; Compound 2.45 preserves renal function and reduces tissue damage in Col4a3−/− mice (the preclinical mouse model of Alport syndrome).

GY10263

DDR-TRK-1

1934246-19-1

DDR-TRK-1 (DDR1 inhibitor 6j) is a potent, selective selective DDR1 inhibitor with IC50 of 9.4 nM, also potently inhibits TRK family with IC50 of 18-100 nM; DDR-TRK-1 inhibits colony formation and migration of Panc-1 pancreatic cancer cells. In cellular and mouse models of lung fibrosis, DDR-TRK-1 inhibits signaling, expression of fibrotic markers and fibrotic features such as hydroxproline expression; DDR-TRK-1 is selective in KINOMEscan at 1 uM,t he closest off target is CDK11 (370 nM).

GY06883

Dual DDR1 and DDR2 inhibitor 5n

2241813-33-0

Dual DDR1 and DDR2 inhibitor 5n is a highly potent, selective, dual Discoidin domain receptor DDR1 and DDR2 inhibitor with Kd of 7.9 and 8.0 nM, IC50 of 9.4 and 20.4 nM, repectively; displays significant selectivity against a panel of 403 wild-type kinases at 1 uM (Abl1 IC50=494 nM); dose-dependently inhibited lipopolysaccharide (LPS)-induced interleukin-6 (IL-6) release in mouse primary peritoneal macrophages (MPMs), attenuates lung pathophysiologic changes in LPS-challenged mice, effectively decreases the levels of TNF-α and IL-6 both in BALF and serum.

GY06777

DDR inhibitor X

1644069-80-6

DDR inhibitor X is a potent discoidin domain receptor (DDR) inhibitor with IC50 of 3.3 nM for DDR2, and shows 53% inhibition on DDR1 at 1.5 nM.

GY10031

VU6015929
