Abstract

The invention discloses a quinoline and quinazoline derivative I, a preparation method, an intermediate C, composition and an application. The preparation method comprises two methods, wherein the first method comprises steps as follows: 1, a compound A and a compound B react in a solvent under the action of alkali 1 to obtain a compound C; and 2, the product C obtained in the step 1 reacts with a compound D under the action of alkali 2; and the second comprises step as follows: the compound A and a compound E react in the solvent under the action of the alkali 1. The invention further provides the application of the compound represented in formula I or medicine composition in preparation of an EGFR (epidermal growth factor receptor) tyrosine kinase inhibitor, an A431 or H1975 cell proliferation inhibitor or medicine for preventing or treating tumor diseases. The provided compound has better antitumor activity.

Description

Technical field [0001] The present invention specifically relates to a quinoline and quinazoline derivatives, preparation methods, intermediates, compositions and applications. Background technique [0002] Protein kinases play an important role in cell signal transduction. It can transfer phosphate groups from ATP to specific amino acid residues of functional proteins, triggering a series of biochemical reactions. According to the types of amino acids used as substrates during phosphorylation, protein kinases can be divided into serine-threonine kinases (STKs) and tyrosine kinases (PTKs). Among them, PTKs can be divided into three categories: ①receptor protein tyrosine kinases (RPTKs), which are single transmembrane proteins, have been found in more than 50 species in vertebrates; ②cytoplasmic tyrosine kinases, such as Src Family, Tec family, JAK family, etc.; ③Nuclear tyrosine kinases such as Abl and Wee. [0003] The extracellular domain of RPTKs is a ligand binding domain. T...
