EphB Inhibitor

JI-101 is an orally active multi-kinase inhibitor. JI-101 inhibits EphB4, VEGFR-2 and PDGFR-β. JI-101 exhibits anticancer activity. JI-101 can be used in research related to ovarian cancer.

EphB4-IN-1 is a selective EphB4 tyrosine kinase inhibitor with IC₅₀ values of 0.16-0.30 μM. EphB4-IN-1 binds to the ATP binding site of EphB4 in a DFG-in conformation, forming four stable intermolecular hydrogen bonds. EphB4-IN-1 also inhibits Src, Abl1, Lck, and EGFR kinases. EphB4-IN-1 inhibits EphB4 autophosphorylation. EphB4-IN-1 can be used for the research of cancer, such as non small cell lung cancer.

JI-101 hydrochloride is an orally active angiogenesis inhibitor and anticancer agent with 55% oral bioavailability in Sprague Dawley rats, high permeability, and no P-gp substrate activity.JI-101 hydrochloride modulates angiogenesis signaling pathways in tumor vessel beds, downregulates EphB4, targets EphB4, VEGFR-2, and PDGFR-β, and inhibits multiple stages of tumor angiogenesis.JI-101 hydrochloride exerts activity against cancer cells and xenografts, exhibits mild to moderate inhibition of CYP3A4, and shows stability in pre-clinical and human liver microsomes.JI-101 hydrochloride undergoes rapid oral absorption in Sprague Dawley rats, has extensive tissue distribution with preferred lung uptake, and is excreted via bile with mono- and di-hydroxy metabolites, with feces as the primary elimination route.JI-101 hydrochloride can be used for the research of ovarian cancer and solid tumors.

EphB4-IN-2 is a tyrosine kinase inhibitor targeting the Eph family and Src family. EphB4-IN-2 binds to the ATP-binding site of the kinase domain of EphB4, and exhibits high affinity for tyrosine kinases with threonine as the gatekeeper residue, such as Abl, Lck and Src. EphB4-IN-2 can be used in research related to tumor-associated angiogenesis.
