Abstract
The invention discloses pivaloyl amido chloro benzo [ d]Aza derivatives
Description
(I) technical field
The invention relates to an application of quinazoline compounds, in particular to pivaloyl amino chloro benzo [ d]Aza derivatives
Application of the quinazoline compound in preparing a medicament for preventing or treating human cervical cancer.
(II) background of the invention
The quinazoline compounds have a plurality of good biological activities and are widely applied in the field of medicine, particularly, some quinazoline derivatives with special structures have obvious antiviral activity, antibacterial activity, antitumor activity and the like, and the quinazoline compounds are marketed as antitumor drugs. For example, Gefitinib (Gefitinib) and Erlotinib (Erlotinib) are marketed for the treatment of lung cancer, and Lapatinib (Lapatinib) is marketed for the treatment of breast cancer, both of which belong to the quinazoline class of compounds. Novel quinazoline compounds and their biological activities are also commonly reported in the literature (see y. -y. ke, h. -y. shiao, y. c. hsu, c. -y. Chu, w. -c. wang, y. -c. lee, w. -h. lin, c. -h. chen, j. t. a. hsu, c. -w. chang, c. -w.lin, t. -k. yeh, y. -s.chao, m.s.coumar, h. -p.hsieh, chemed chem 2013, 8, 136-148; a.garofalo, a.farce, s.ravez, a.lemoine, p.six, p.vatte, l. gosense, p.depenux, j.chem.1204, d.m.1189, d.1189). Of course most quinazoline compounds do not have anti-tumor activity.
Disclosure of the invention
The invention aims to provide a novel quinazoline compound, namely pivaloylaminochlorobenzo [ d]Aza derivatives
The application of the quinazoline compound has good inhibition effect on human cervical cancer cell strains Siha under a certain dosage; and the preparation method of the compound is simple and convenient, easy to operate, easy to obtain raw materials, low in production cost and suitable for industrial application.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a pivaloylaminochlorobenzo [ d ] compound represented by formula (I)]Aza derivatives
The application of the quinazoline compounds in preparing medicaments for preventing or treating tumors, in particular to the application in preparing medicaments for preventing or treating human cervical carcinoma:
