Definitions
- the present invention relates to a salt of a 4-aniline quinazoline derivative. Specifically, the present invention relates to a salt form of N- ⁇ 4-[3-chloro-4-(3-fluoro-benzyloxy)phenylamino]-quinazolin-6-yl acrylamide, and preparation thereof A method, a pharmaceutical composition comprising the salt forming form, and the use of the salt forming form for preventing and/or treating a tumor. Background technique
- Cancer is thought to be a disease mediated by intracellular signaling systems or signaling mechanisms.
- the cells receive many instructions from outside the cell to direct the cell to proliferate.
- the purpose of the signaling system is to accept these or other signals on the cell surface, introduce it into the cell, and then pass these signals to the nucleus, cytoskeleton, and affect the transcription of the gene. And protein synthesis.
- the most common cause of cancer is a series of defects, which can be defects in certain proteins (when they are mutated), or defects in the regulation of the amount of protein in the cell, resulting in overproduction or underproduction of the protein.
- defects usually, there is a significant damage in the cells that causes a constitutive state, thereby causing the nucleus to receive a proliferative signal, and in fact these signals do not exist. This can happen through a variety of mechanisms.
- cells will start to produce true growth factors for their own receptors, so-called autocrine loop mechanisms.
- Epidermal growth factor receptor has been identified as a critical driver of cell growth and reproduction. In common tumors, such as non-small cell lung cancer, epidermal growth factor receptors are abundantly expressed, far beyond the normal range.
- the epidermal growth factor receptor family consists of EGFR (Erb-Bl), Erb-B2 (HER-2/neu), Erb-B3 and Erb-B4.
- Epidermal growth factor receptors are involved in disease progression in most cancers, particularly colon and breast cancer. Overexpression and mutation of this receptor have been clearly identified as major risk factors for breast cancer with poor prognosis.
- EGFR belongs to the family of protein tyrosine kinases (PTKs), a class of enzymes that catalyze the transfer of a phosphate group from hydrazine to a tyrosine residue located on a protein substrate.
- PTKs protein tyrosine kinases
- Protein tyrosine kinases play a role in normal cell growth. Overexpression of EGFR causes the receptor to be activated in the absence of ligand, phosphorylating certain proteins, and producing a signal for cell division. Therefore, EGFR, through the action of its own tyrosine kinase, leads to excessive amplification of weak signals, causing excessive proliferation of cells.
