ddr inhibitor

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.

DDR1/2 Inhibitor-2 (Example 31) serves as an inhibitor of DDR1/DDR2, exhibiting IC50 values below 100 nM. It is applicable in cancer and fibrotic disease research [1].

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.

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.

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

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).

S 16020-2 is an olivacine derivative, and DNA topoisomerase II inhibitor endowed with a remarkable antitumor activity against various experimental tumors.

ATR-IN-11 (Compound Hit01) is a potent inhibitor of ataxia capillaris and Rad3-related (ATR) kinases. As a promising lead compound for developing drugs targeting the ATR kinase, a key regulatory protein in the DNA damage response (DDR) that senses replication stress (RS), ATR-IN-11 has significant potential for cancer research.

ATR-IN-23 (Compound 34), a potent and selective ATR inhibitor, exhibits an IC50 of 1.5 nM, has demonstrated antiproliferative effects on LoVo cells, and induces synthetic lethality in HT-29 cells, suggesting its utility in researching DNA damage response (DDR)-deficient cancers [1].
