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.

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.

Merestinib (LY2801653) is an orally available, small molecule inhibitor of the proto-oncogene c-Met (Ki: 2 nM) with potential antineoplastic activity. Merestinib electively binds to c-Met, thereby inhibiting c-Met phosphorylation and disrupting c-Met signal transduction pathways. This may induce cell death in tumor cells overexpressing c-Met protein or expressing the constitutively activated c-Met protein.

Sitravatinib (MGCD516) is an inhibitor targeting multiple RTKs involved in driving sarcoma cell growth, including c-Met, c-Kit, PDGFRα β, PDGFR, and Axl.

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.

WRG-28 is a potent and selective, allosteric discoidin domain receptor 2 (ddr2) inhibitor(IC50 : 230 nM)

SR-302 is a potent and selective inhibitor of DDR p38, with IC50 values of 0.125 μM for p38α, 0.023 μM for DDR1, and 0.018 μM for DDR2. It is utilized in research related to fibrotic diseases, such as kidney and lung fibrosis, atherosclerosis, and various types of cancer.

USP1-IN-11 (compound 38-P2) is a selective, reversible, and non-competitive inhibitor of USP1 (Ubiquitin-specific protease 1). It activates the DDR (DNA damage repair) pathway, leading to cell cycle arrest and apoptosis, thereby inhibiting cell survival. USP1-IN-11 increases sensitivity to Olaparib in drug-resistant cells and works synergistically with Andrographolide in cancer cells with functional BRCA. In the MDA-MB-436 xenograft model, USP1-IN-11 demonstrates significant dose-dependent antitumor activity.

USP1-IN-11 (compound 38-P2) is a selective, reversible, and non-competitive inhibitor of USP1 (Ubiquitin-specific protease 1). It promotes the activation of the DDR (DNA damage repair) pathway, inducing cell cycle arrest and apoptosis, thereby inhibiting cell viability. USP1-IN-11 increases the sensitivity of cells resistant to Olaparib and shows synergistic effects with Andrographolide in cancer cells with normal BRCA function. In the MDA-MB-436 xenograft model, USP1-IN-11 exhibits a significant dose-dependent antitumor effect.

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).

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.

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

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].
