| | KX2-391 Usage And Synthesis |
| Uses | A synthetic, orally bioavailable small molecule and non-ATP competitive Src tyrosine kinase inhibitor with an IC50 of average 72 nM. | | Uses | KX2-391 is a Src Inhibitor with efficacy against certain hepatic and leukemia cell lines. | | Biological Activity | kx2-391 is a highly selective inhibitor of src kinase with ic50 value of 20nm [1].kx2-391 is a non-atp competitive inhibitor of src. it is the first inhibitor that targets src kinase within the substrate binding site. kx2-391 inhibits src catalyzed trans-phosphorylation of fak, shc, paxillin as well as src kinase autophosphorylation. kx2-391 has no effects on pdgfr, egfr, jak1, jak2 and lck demonstrating it as a selective inhibitor. it is also found to be an inhibitor of tubulin polymerization through binding to the unique confirmation on heterodimeric tubulin. in cellular assays, kx2-391 shows growth inhibition in nih3t3/c-src527f cells and syf/c-src527f cells with gi50 values of 23nm and 39nm, respectively [1, 2].since src acts as a regulator in cell proliferation survival, motility and invasiveness, kx2-391 is potent against a variety of solid tumors and many leukemia tumors. it is shown to inhibit primary tumor growth and to suppress metastasis [2]. | | target | Src (HuH7) | | references | [1] fallah-tafti a, foroumadi a, tiwari r, et al. thiazolyl n-benzyl-substituted acetamide derivatives: synthesis, src kinase inhibitory and anticancer activities. european journal of medicinal chemistry, 2011, 46(10): 4853-4858.
