The preparation method disclosed by the invention comprises the following steps: carrying out an acylation reaction between 1-methoxynaphthalene and substituted phenylacetic acid to prepare 1-(4-methoxynaphthalene-1-yl)-2-substituted phenylethane-1-one; carrying out a reaction between 1-(4-methoxynaphthalene-1-yl)-2-substituted phenylethane-1-one and DMF-DMA to prepare (E)-3-(dimethylamino)-1-(4-methoxynaphthalene-1-yl)-2-substituted phenylpropyl-2-ene-1-one, and finally performing a ring closing reaction with guanidine hydrochloride and potassium carbonate to obtain the naphthalene ring-aminopyrimidine compound as shown in the general formular (I) in the specification. The naphthalene ring-amidopyrimidine compound disclosed by the invention has good activity of inhibiting tubulin polymerization, can effectively inhibit the proliferation activity of human breast cancer MCF-7 cells, can be used as a novel lead compound for antitumor drug research, and is suitable for market popularization 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...
