Abstract

The invention discloses a naphthalene ring-aminopyrimidine type compound, a preparation method and application thereof, and belongs to the technical field of preparation of new drug compounds. The preparation method disclosed in the present invention comprises: 1-methoxynaphthalene and substituted phenylacetic acid are prepared by acylation reaction to obtain 1-(4-methoxynaphthalene-1-yl)-2-substituted phenylethane-1-one , and then react with DMF-DMA to obtain (E)-3-(dimethylamino)-1-(4-methoxynaphthalene-1-yl)-2-substituted phenyl prop-2-ene-1- Ketone, finally obtains the naphthalene ring-amino pyrimidine type compound (I) shown in the general formula (I) in the ring-closing reaction with guanidine hydrochloride and potassium carbonate. The naphthalene ring-aminopyrimidine type compound of the present invention has a good activity of inhibiting tubulin polymerization, and can effectively inhibit the proliferation activity of human breast cancer MCF-7 cells, and can be used as a leading compound for novel antitumor drug research, and is suitable for the market promotion and application.

Description

technical field [0001] The invention belongs to the technical field of compound preparation, and in particular relates to a naphthalene ring-aminopyrimidine type compound, a preparation method thereof and an application in preparation of tubulin inhibitor antitumor drugs. Background technique [0002] Microtubules are composed of α and β tubulin dimers and are key components of the eukaryotic cytoskeleton. Microtubules are involved in a variety of cellular functions such as maintenance of cell shape, cell signaling, secretion, intracellular transport, and cell division. During mitosis in eukaryotic cells, microtubules form a spindle that guides chromosome division into two daughter cells. Disruption of microtubule function can cause dividing cells to arrest in the G2 / M phase, leading to apoptosis. Tubulin has become one of the important targets in the current research and development of anticancer drugs. Although paclitaxel, vinblastine and other tubulin inhibitor antineo...
