Description

A kind of new inhibitor of EGF-R ELISA and application thereof
[technical field]
The present invention relates to suppress skin factor acceptor and associated receptor technical field, specifically, is a kind of new inhibitor and application thereof of EGF-R ELISA.
[background technology]
EGF-R ELISA (EGFR) is one type of important film Tyrosylprotein kinase growth factor receptors of striding, and is positioned cytolemma, is equal to HER2/ErbB-2/Neu/pl85, HER3/ErbB-3, HER4/ErbB-4 and is included into HER/ErbB family.By extracellular region, stride the film district and intracellular region three parts are formed.Its part comprises Urogastron (epidermal growth factor; EGF), transforming growth factor-alpha (transforming growth factor-α; TGF-α), the plain (betacellulin of beta cell; BTC), amphiregulin (amphiregulin), epidermin (epiregulin), heparin-bounding Urogastron (heparin-binding EGF, HB-EGF) etc., important with EGF and TGF-α.EGFR combines the back interaction to form homodimer or heterodimer with its ligand extracellular region.Compare with homodimer, heterodimer plays a part even more important in signal transmission such as mediated cell propagation, differentiation, migration.Dimeric formation causes the activation in Tyrosylprotein kinase district in the born of the same parents, and then through changeing phosphorylation and phosphorylation, impels receptor tyrosine residue phosphorylation, starts a series of cascade reactions such as ras-MAPK, PI3K, PLC γ/PKC, STAT.Signal is passed in the nucleus.Finally cause a series of genes involved activation, promote cell from G 1Phase carries out the transition to the S phase, thereby genetic expression in examining and cell Growth and Differentiation are produced regulating effect.
At present existing broad research confirms the mistake of EGFR to be expressed in SCCHN, and (head and neck squamous cell carcinoma HNSCC) reaches 90%~100%, and kidney reaches 50%~9O%; Lung cancer reaches 40%~8O%; Mammary cancer reaches 14%~90%, and colorectal cancer (colorectal cancer) reaches 25%~77%, and ovarian cancer reaches 25%~70%; Prostate cancer reaches 39%~47%; Neurogliocytoma reaches 40%~63%, carcinoma of the pancreas reach 30%~50% and bladder cancer reach 31%~48%, in the multiple noumenal tumour such as cancer of the stomach, thymus neoplasms relevant report is also arranged all in addition.The over-expresses of EGFR often indicates that prognosis of patients is poor, shift fast, to chemicotherapy resistances, hormone resistance, existence weak point etc.Therefore, suppress propagation and the transfer that the EGFR Tyrosylprotein kinase can stop tumour cell effectively.
The cancer cell multiplication that the objective of the invention is to utilize imidazo [1,2-a] pyrazine analog derivative to suppress the active of EGFR and regulated and control.
