Abstract
The invention provides a brand new anilinoquinazoline compound of the structure in the formula (I). The anilinoquinazoline compound has a tyrosine kinase inhibiting effect. Real-time fluorogenic quantitative PCR measurement results indicate that the VEGF expression quantity is reduced by 1000 times or more through the target compound, the inhibiting effect on VEGF expression is quite obvious, and the inhibiting activity is far higher than that of vandetanib. Further experiments indicate that the target compound has the better antineoplastic activity compared with vandetanib under the anoxia condition and is expected to be the medicine for treating tumors.
Description
technical field [0001] The invention relates to the technical field of medicinal chemistry, in particular to a nitroimidazole group-containing aniline quinazoline compound and a preparation method and application thereof. Background technique [0002] The following descriptions of the background related to the present invention are provided to assist an understanding of the present invention and should not be considered as prior art to the present invention. All cited publications are incorporated by reference in their entirety. [0003] Tumor cells grow with blood vessels as the center. Cells that are more than 180 μm away from blood vessels are prone to form necrotic areas due to decreased oxygen concentration and lack of nutrients. The low oxygen concentration area at the front of the necrotic area is hypoxic tissue. Hypoxic cells account for about 10-50% of tumor cells. %, most of them are in the G0 phase of cell dynamics, showing no proliferation or slow proliferation,...
