R1498 is an inhibitor of cyclin-dependent kinase 2. It also acts by targeting angiogenesis and mitosis pathways. It is well-tolerated and orally active for hepatocellular carcinoma and gastriccancer treatment.
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 gastriccancer cells and xenografts, inducing apoptosis [2].
