c Kit IN 2

c-Kit-IN-2 is a c-KIT-targeted inhibitor with an IC₅₀ of 82 nM. It exhibits favorable anti-proliferative effects on three gastrointestinal stromal tumor cell lines GIST882, GIST430, and GIST48, with corresponding GI₅₀ values of 3 nM, 1 nM, and 2 nM, respectively.

JNK-IN-8 (JNK Inhibitor XVI) is an effective JNK inhibitor that inhibits JNK1, JNK2, and JNK3 with IC₅₀ values of 4.7, 18.7, and 1 nM, respectively. JNK-IN-8 offers the advantages of minimal off-target activity, sustained inhibition, and high specificity. JNK-IN-8 primarily acts by blocking the JNK/c-Jun signaling pathway, inhibiting the phosphorylation of the downstream transcription factor c-Jun, thereby regulating the expression of genes associated with inflammatory responses, apoptosis, and stress responses. JNK-IN-8 can be used in research on tumors, inflammation, and neurological diseases.

Famitinib (SHR1020) is a potent orally active multi-targeted kinase inhibitor that effectively inhibits the activity of c-kit, VEGFR-2, and PDGFRβ with IC50 values of 2.3 nM, 4.7 nM, and 6.6 nM, respectively [1]. It demonstrates remarkable antitumor properties in human gastric cancer cells and xenografts, inducing apoptosis [2].

4-(3-Tosyl-2-(tosylmethyl)propanoyl)benzoic acid-glu(PEG24-Me)-val-cit-NH-benzyloxyformic acid-MMAE is a component of a drug-linker conjugate for ADC. It includes a linker and a biologically active small molecule toxin, MMAE. This compound can conjugate with NN2101 (anti-c-Kit) to form NN3201, which rapidly internalizes and inhibits SCF-driven signal transduction, inducing cell cycle arrest and apoptosis through payload delivery. NN3201 exhibits significant c-Kit-dependent antitumor activity in various tumor models, such as small cell lung cancer (SCLC) and gastrointestinal stromal tumors (GIST).

AMG-25 (c-Kit-IN-5-1) is a selective and potent c-Kit inhibitor that inhibits c-Kit, KDR, p38, Lck, and Src, and can be used in the study of mast cell-associated fibrosis.

OSI-930, an orally active inhibitor of c-Kit and the vascular endothelial growth factor receptor-2 (VEGFR-2), targets cancer cell proliferation and blood vessel growth (angiogenesis) in tumors.

Midostaurin (PKC412) is a multi-targeted tyrosine kinase inhibitor with antitumor activity, exhibiting IC50 values ranging from 22 to 500 nM against PKCα/β/γ, Syk, Flk-1, Akt, PKA, c-Kit, c-Fgr, c-Src, FLT3, PDFRβ, and VEGFR1/2. Midostaurin is indicated for the treatment of acute myeloid leukemia (AML) and systemic mastocytosis (SM).

Pyridostatin Trifluoroacetate Salt is a G-quadruplexe stabilizer with Kd of 490 nM in a cell-free assay, which targets a series of proto-oncogenes including c-kit, K-ras and Bcl-2.

Henatinib is an orally active small molecule multi-kinase inhibitor with broad antitumour effects. henatinib inhibits the activity of VEGFR-2 (IC50: 0.6 nM), c-kit (IC50: 3.3 nM), PDGFR (IC50: 41.5 nM). henatinib significantly inhibits VEGFR-2 phosphorylation and its downstream signalling pathways in human umbilical vein endothelial cells (HUVECs). Henatinib significantly inhibited VEGFR-2 phosphorylation and its downstream signaling pathway in human umbilical vein endothelial cells (HUVECs).

Multi-kinase-IN-2 is an orally active inhibitor of angiokinases. multi-kinase-IN-2 significantly inhibits the activity of angiokinases such as VEGFR-1/2/3, PDGFRα/β, FGFR-1, LYN and c-KIT kinases. -IN-2 significantly attenuates phosphorylation of AKT and ERK proteins, induces apoptosis and has anticancer effects.

Famitinib malate (SHR1020) is an orally active multi-targeted kinase inhibitor that effectively inhibits the activity of c-kit, VEGFR-2, and PDGFRβ with IC50 values of 2.3 nM, 4.7 nM, and 6.6 nM, respectively. It induces cell apoptosis and demonstrates potent antitumor activity in human gastric cancer cells and xenografts, making it a valuable compound for cancer research.

Apatinib, also known as Rivoceranib and YN-968D1, is an orally bioavailable, small-molecule receptor tyrosine kinase inhibitor with potential antiangiogenic and antineoplastic activities. The free-base form is also known as Rivoceranib. Apatinib selectively binds to and inhibits vascular endothelial growth factor receptor 2, which may inhibit VEGF-stimulated endothelial cell migration and proliferation and decrease tumor microvessel density. In addition, this agent mildly inhibits c-Kit and c-SRC tyrosine kinases.

Imatinib Impurity E is a specific impurity found in Imatinib, an orally available inhibitor of multiple tyrosine kinases, including BCR/ABL, v-Abl, PDGFR, and c-kit. Imatinib (STI571) operates by semi-competitively inhibiting enzyme activity; it binds adjacent to the ATP binding site, inducing a closed or self-inhibited conformation [1] [2] [3] [4]. Additionally, Imatinib acts as an inhibitor against SARS-CoV and MERS-CoV [5].

FAK-IN-14 is a highly effective focal adhesion kinase (FAK) inhibitor that induces apoptosis and cell cycle arrest. FAK-IN-14 has weak inhibitory effects on Akt, c-kit, MEK1/2 and mTOR, but has significant inhibitory effects on FAK, FGFR1 and Pyk2.
