Abstract

The invention relates to a medicine for treating malignant tumor, in particular to an application of seven oceanic bromophenol compounds to the preparation of the medicine for treating malignant tumor. The bromophenol compounds of the invention and the derivatives thereof such as salt, ester, aether, etc. have favorable inhibition effect on protein tyrosine kinase, and can be used for preventing and treating the malignant tumor of high expression C-kit receptor.

Description

The application of ocean bromine phenolic compound in preparation treatment malignant tumor medicine
Technical field
The present invention relates to treat the medicine of malignant tumor, specifically the preparation method of ocean bromine phenol compounds, pharmacologically active, purposes and pharmaceutically acceptable salt, ester, ether and other tangible chemical equivalence thing; (protein tyrosinekinase, PTK) inhibitor can be used for treating the malignant tumor of various high expressed C-kit receptors as protein tyrosine kinase for this chemical compound and derivant thereof.
Background technology
Along with the development that molecular weight tumor is learned, the research of antitumor drug also acts on the newtype drug of molecular target from traditional cell toxicity medicament trend.Protein tyrosine kinase (PTK) is one of target of treatment of cancer, proto-oncogene C-kit is the congener of HZ4 cat family sarcoma virus kit oncogene, be positioned at No. 4 chromosomes long-armed on, the coding 145-165kDa transmembrane receptor (CD117), have tyrosine kinase activity.Its product is an III type tyrosine protein kinase growth factor receptors, its similar is in M-CSF and platelet-derived thing growth factor receptors, belong to the immunoglobulin superfamily member, have outer 5 the immunoglobulin-like similar structures of born of the same parents ligand binding domain, stride membrane-proximal region and tyrosine protein kinase district in film district, the film.In normal structure, C-kit albumen is expressed at mastocyte, Interstitial cell, melanocyte and galactophore epithelial cell.The autocrine of C-kit signal path and paracrine stimulate the generation of participant's tumor, and play the effect of oncogene in kinds of tumors.C-kit albumen is somatomedin and stem cell factor (SCF) receptor, and the interaction between it and part stem cell factor can activate intrinsic tyrosine kinase, makes the intracellular protein phosphorylation thereupon, causes the activation of signal transduction path in the cell.Proto-oncogene C-kit sudden change can cause that the proteic extracellular fragment of C-kit or born of the same parents' inner segment change, cause C-kit protein receptor continuous openness, the continuous autophosphorylation of various substrate proteins, make the conducted signal cascade of characteristics such as regulating cell differentiation, propagation, apoptosis, chemotactic and adhesion discharge and expansion, promoted the cell growth by this approach, suppressed apoptosis, the normal biological characteristics of cell disappears and develops into tumor cell.The oncogenic potential of C-kit is confirmed in many experiments, discoveries such as Hines, transfection the MCF-7 breast cancer cell of the C-kit growth and the multiplication rate that tie up in the culture medium speed, and this propagation can be prevented by anti-C-kit antibody; Caruana etc. to transfection the reorganization NIH3T3 fibroblast of C-kit gene cultivate, find that the activation of C-kit can promote cell proliferation and produce the Phenotype of a variation that this has obtained confirmation in cell clone and nude mice tumor model.In recent years, more and more researchers research is sought the small molecular protein tyrosine kinase inhibitor, thereby is developed new type anticancer medicine efficiently about the tumor of C-kit receptor as molecule target treatment high expressed C-kit receptor.
From modern medicines research and development historical as seen, the Application and Development of each original new drug, at first from the discovery of certain class new type natural lead compound, the ocean is origin of life ground, in the unique ecological environment of ocean, Sargassum can produce some very distinctive active substances mostly.The inventor obtains the bromine phenolic compound of a novel structure from a kind of marine red alga, active testing shows that it has very strong inhibition activity to the PTK enzyme, can be used for the control of the malignant tumor of high expressed C-kit receptor, comprise gastrointestinal stromal tumor (GIST), Mastocytosis type leukemia, germ cell tumor, small cell lung cancer, acute leukemia, neuroblastoma, melanoma, ovarian cancer and breast carcinoma etc.
Summary of the invention
