MedKoo CAT#: 201611

CAS#: 900573-88-8

Description: JI-101 is an orally active inhibitor of vascular endothelial growth factor receptor 2 (VEGFR2), platelet-derived growth factor receptor beta (PDGFRb), and the ephrin B4 receptor B4 (EphB4) with potential antiangiogenic and antineoplastic activities. Angiogenesis inhibitor JI-101 binds to and inhibits VEGFR2, PDGFRb and EphB4, which may inhibit tumor angiogenesis and, so, cellular proliferation in tumor cells overexpressing VEGFR2, PDGFRb and EphB4. The receptor tyrosine kinases VEGFR2, PDGFRb and EphB4 may be overexpressed in a number of different cancer cell types and may play crucial roles in tumor angiogenesis.

Additional Information

JI-101 is a novel orally active kinase inhibitor, which has shown potent in vitro and in vivo anticancer activity against a variety of cancer cell lines and xenografts. It is currently entering Phase II clinical development for the treatment of solid tumors. Overall, the oral bioavailability of JI-101 is 55% and the primary route of elimination for JI-101 is feces.  (source: Arzneimittelforschung. 2012 Jan;62(1):27-34. Epub 2012 Jan 10.)
