DDR1-IN-1 is a type II, subtype-selective discoidin domain receptor (DDR) tyrosine kinase inhibitor (DDR1/2 IC50 = 105 nM/413 nM) that effectively blocks collagen-induced DDR1 pY513 autophosphorylation in U2OS cells (EC50 = 86.76 nM) with excellent selectivity over a panel of >380 kinases. DDR1-IN-1 inhibits DDR2-mediated MT1-MMP activation in human rheumatoid synovial fibroblasts (RASF) upon collagen stimulation (IC50 < 2.5 μM) and enhances PI3K/mTOR inhibitor GSK2126458 antiproliferation efficacy in SNU-1040 colorectal cancer culture (123%, 70%, 50% of control, respectively, post 48-hr 250 nM DDR1-IN-1, 82.5 nM GSK2126458, or combined treatment).
DDR1-IN-1 protects cells from apoptosis by inhibiting collagen-mediated Bcl-2-interacting killer (BIK) induction at both mRNA and protein levels.[1]
Potent, selective, type II tyrosine kinase inhibitor against discoidin domain receptor DDR1/2.

During tumour dissemination, invading breast carcinoma cells become confronted with a reactive stroma, a type I collagen-rich environment endowed with anti-proliferative and pro-apoptotic properties. To develop metastatic capabilities, tumour cells must acquire the capacity to cope with this novel microenvironment.
The role of pathological angiogenesis on liver fibrogenesis is still unknown. Here, we developed fibrotic microniches (FμNs) that recapitulate the interaction of liver sinusoid endothelial cells (LSECs) and hepatic stellate cells (HSCs). We investigated how the mechanical properties of their

We present a new strategy for systematic identification of phosphotyrosine (pTyr) by affinity purification mass spectrometry (AP-MS) using a Src homology 2 (SH2)-domain-derived pTyr superbinder as the affinity reagent. The superbinder allows for markedly deeper coverage of the Tyr phosphoproteome
A Membrane-Type-1 Matrix Metalloproteinase (MT1-MMP) - Discoidin Domain Receptor 1 Axis Regulates Collagen-Induced Apoptosis in Breast Cancer Cells
The Journal of biological chemistry, 292(16), 6633-6643 (2017-03-09)
Membrane-type 1 matrix metalloproteinase (MT1-MMP) is a membrane-bound MMP that is highly expressed in cells with invading capacity, including fibroblasts and invasive cancer cells. However, pathways of MT1-MMP up-regulation are not clearly understood. A potential physiological stimulus for MT1-MMP expression
