The invention relates to a purpose of a medicine which is prepared by triptolide and is used for curing tumor that is relevant to c-KIT tyrosine kinase. The invention verifies that a micromolecule natural product triptolide (TPL) can down-regulate the protein expression of D816V point mutation c-KIT for the first time, inhibit the phosphorylation thereof and induce the cell apoptosis of STI571 resistance c-KIT point mutation (D816). The invention discloses a novel micromolecule stayer of tyrosine kinase, more particularly overcomes the problem that the resistance property of the medicine STI 571 can be inhibited by the first-line tyrosine kinase that is used on the clinic at present. The TPL can be used for developing a novel specific medicine for curing tumors being relevant to c-KIT mutation, such as gastrointestinal stromal tumor, systemic mastocytosis and small cell lung cancer, etc.

The subject invention concerns peptide molecules that specifically inhibit the enzymatic function of tyrosine kinases, including the JAK and EGF receptor (EGFR) family of kinases, to autophosphorylate, i.e., to transfer a phosphate group from ATP to an amino acid in the kinase. Phosphorylation of proteins is the most fundamental method for signal transduction among proteins in a cell. Inhibition of tyrosine kinase autophosphorylation activities inhibits the enzyme's signaling and shuts down the functioning pathways originating from the enzyme. The JAK2 and EGFR tyrosine kinases are involved in both inflammatory disorders and cancer. In these disorders, the tyrosine kinases can often be activated in an uncontrolled fashion. The subject application also concerns antibodies that bind to a tyrosine kinase autophosphorylation site. The subject invention also concerns pharmaceutically acceptable formulations of the subject peptides and antibodies, and methods for treating inflammatory and oncological disorders by inhibiting tyrosine kinase signaling in these situations by administering a peptide or antibody of the present invention.
