DDR-TRK-1 was shown to inhibit the kinase activity of Discoidin Domain Receptor 1 (DDR1) with an IC50 value of 9.4 nM. DDR receptors are linked to the progression of various human diseases, including fibrotic disorders such as pulmonary fibrosis, as well as atherosclerosis and cancer. DDR-TRK-1 showed a therapeutic effect in a mouse model of pulmonary fibrosis and inhibited Panc-1 pancreatic cancer cell colony formation and migration. DDR-TRK-1 also inhibits the TRK family kinases TRKA, TRKB, and TRKC, which are selectively expressed in neuronal tissue. DDR-TRK-1N is the negative control compound.
