Ningetinib is a potent, orally bioavailable tyrosine kinase inhibitor for Axl, VEGFR2 and c-Met with IC50 values of <1.0, 1.9 and 6.7 nM, respectively. Ningetinib (CT053PTSA) inhibits HGF and VEGF-stimulated HUVEC proliferation and microvascular angiogenesis in rat aortic rings with IC50 values of 8.6 and 6.3 nM, respectively.
In vivo, Ningetinib (3 mg/kg; orally) treatment on U87MG tumor-bearing nude mice potently inhibits the phosphorylation of c-Met and its downstream signaling kinases AKT and ERK1/2 for up to 6 hours in tumor tissues.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
