Abstract
The inventionDiscloses an isobutyrylaminobenzo [ d]Aza derivatives
The application of the quinazoline compound in preparing the medicaments for preventing or treating the human lung cancer provides a novel quinazoline compound with good anticancer (particularly human lung cancer) activity, and is expected to be applied in preparing the medicaments for preventing or treating the human lung cancer; the invention provides isobutyrylaminobenzo [ d]Aza derivatives
Description
(I) technical field
The invention relates to isobutyrylaminobenzo [ d]Aza derivatives
The application of the fluoroquinazoline compound in preparing the medicines for preventing or treating tumor diseases.
(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.vachatte, l.gos, p.depenux, j.chem. 1204, d. chem. 1189). Of course most quinazoline compounds do not have anti-tumor activity.
Disclosure of the invention
According to the inventionAims at providing a novel quinazoline compound-isobutyrylaminobenzo [ d]Aza derivatives
The application of the quinazoline compounds in preparing medicaments for preventing or treating human lung cancer has obvious inhibition rate on human lung cancer cell strains A-549 under 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 present invention provides an isobutyrylaminobenzo [ d ] compound represented by the formula (I)]Aza derivatives
The application of the quinazoline compounds in preparing medicaments for preventing or treating human lung cancer,
further, the medicament is preferably a medicament for inhibiting the activity of a human lung cancer cell strain A-549.
