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].
Vandetanib Fumarate is an orally available tyrosine kinase inhibitor. Vandetanib Fumarate works by blocking RET (REarranged during Transfection), vascular endothelial growth factor receptor (VEGFR-2, VEGFR-3), and epidermal growth factor receptor and to a
L-Sepiapterin, also known as Sepiapterin, is a precursor compound crucial for the production of tetrahydrobiopterin (BH4), which serves as a coenzyme for endothelial nitric oxide synthase (eNOS). This compound demonstrates its efficacy by improving endothelial dysfunction in small mesenteric arteries from db/db mice and promoting angiogenesis. Moreover, L-Sepiapterin exerts inhibitory effects on cellular proliferation and migration in ovarian cancer cells through the down-regulation of p70S6K-dependent vascular endothelial growth factor receptor-2 (VEGFR-2) expression[1][2].
