ddr-1-in-1

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

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

DDR1-IN-1 dihydrochloride is a selective and potent inhibitor of the DDR1 receptor tyrosine kinase, exhibiting an IC50 of 105 nM, and it demonstrates fourfold reduced potency against DDR2, with an IC50 of 413 nM.

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.

Phosphoramide mustard cyclohexanamine is the active metabolite of cyclophosphamide, an alkylating agent that cross-links DNA strands, organizes cell division and causes cell death, and has antitumor activity.

DDR2-IN-1 (Compound 129) is recognized as a highly effective DDR2 inhibitor, displaying an IC50 value of 26 nM. It is a suitable choice for conducting osteoarthritis research.

DDR1-IN-4 (Compound 2.45) is a highly potent inhibitor that selectively targets Discoidin Domain Receptor 1 (DDR1) autophosphorylation, demonstrating exceptional efficacy with IC50 values of 29 nM for DDR1 and 1.9 μM for DDR2.

DDR1-IN-6 is a potent and selective inhibitor of Discoidin Domain Receptor family member 1 (DDR1), exhibiting remarkable inhibitory activity at an IC50 of 9.72 nM. It effectively suppresses the auto-phosphorylation of DDR1b (Y513) with an IC50 value of 9.7 nM. Furthermore, DDR1-IN-6 displays strong anti-cancer activity.

DDR1-IN-5 is a potent and selective inhibitor of the Discoidin Domain Receptor family, member 1 (DDR1). It effectively inhibits the phosphorylation of DDR1b (Y513) with an IC 50 value of 4.1 nM. Furthermore, DDR1-IN-5 demonstrates remarkable anti-cancer activity. Its inhibitory potency against DDR1 (IC 50 = 7.36 nM) makes it a promising compound for targeted therapy in cancer treatment.

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).

BTX161 is a Thalidomide analogue. BTX161 is a potent CKIα degrader. In human AML cells, BTX161 mediates the CKIα degradation better than Lenalidomide as well as activates DNA damage response (DDR) and p53, and also stabilizes the p53 antagonist MDM2[1].

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].
