Abstract
The invention discloses a cyclohexyl methoxy formyl amino quinazoline compound, and preparation and application thereof. The cyclohexyl methoxy formyl amino quinazoline compound provided by the invention has obvious inhibitory activity on human breast cancer cell strain MCF-7 and human promyelocytic leukemia cell strain HL-60, and is expected to be applied to preparation of medicines for preventing or treating human breast cancer and human lung cancer. The invention provides a preparation method of the cyclohexyl methoxy formamido quinazoline compound, which is simple, easy to operate, easy to obtain raw materials, low in production cost and suitable for practical use.
Description
(I) technical field
The invention relates to a quinazoline compound, in particular to a cyclohexyl methoxy formamido quinazoline compound, a preparation method thereof and application of the compound in preparing a medicament 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
The invention aims to provide a novel quinazoline compound with anticancer activity, namely a cyclohexyl methoxy formamido quinazoline compound, and a preparation method and application thereof, wherein the compound has good inhibition effect on a human lung cancer cell strain A-549, a human breast cancer cell strain MCF-7, a human promyelocytic leukemia cell strain HL-60 or a human cervical cancer cell strain 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:
in a first aspect, the present invention provides a cyclohexylmethoxycarboxamidoquinazoline compound of the formula (i):
