DDR1-IN-1 is a potent and selective DDR1 receptor tyrosine kinase inhibitor with an IC50 of 105 nM; 4-fold less potent for DDR2 (IC50 = 413 nM)[1].

ChEBI: DDR1-IN-1 is a secondary carboxamide resulting from the formal condensation of the carboxy group of 4-[(4-ethylpiperazin-1-yl)methyl]-3-(trifluoromethyl)benzoic acid with the amino group of 5-(5-amino-2-methylphenoxy)-1,3-dihydro-2H-indol-2-one. It is a potent inhibitor of discoidin domain receptor tyrosine kinase 1 and 2 (DDR1/2) with IC50 = 105 nM and 413 nM, respectively. It has a role as an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor. It is a N-alkylpiperazine, a member of benzamides, a member of (trifluoromethyl)benzenes, a secondary carboxamide, an aromatic ether and a member of oxindoles.

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). ent). ned treatment).
