Abstract

The invention discloses a c-Met / histone deacetylase (HDAC) double-target inhibitor based on a crizotinib structure, and a synthesis method and application of the double-target inhibitor. According tothe inhibitor disclosed by the invention, c-Met inhibitor crizotinib and HDAC inhibitor vorinostat are taken as a lead structure to design a double-target inhibitor with a single structure; the crizotinib structure is used as a hat-shaped structure of the HDAC inhibitor to replace aniline acyl in a vorinostat structure; a hydroximic acid structure in the vorinostat is retained as a chelating groupof metal zinc ions; connecting groups with different structures are introduced between the the crizotinib structure and the hydroximic acid structure; and the double-target inhibitor with a single structure is designed through the principle of pharmacophores combination, so that the obtained double-target inhibitor has good inhibition effects on c-Met and HDAC, and can be used for synergisticallyinhibiting the c-Met and HDAC.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a c-Met / HDAC dual-target inhibitor based on the structure of crizotinib and its synthesis method and application. Background technique [0002] In the HGF / MET signaling pathway, HGF activates c-Met, activates the downstream RAS–RAF–MEK–MAPK and PI3K–AKT signaling pathways, and makes the proto-oncogene (c-Myc) and G1 / S-specific cycle protein- The expression of D1 (cyclin D1) increases, and the activity of cell cycle inspection proteins p21 and p27 decreases, promoting cell cycle progression and survival. Histone deacetylase (HDAC) is also a key regulator of cell cycle progression. Inhibiting HDAC can promote the expression of cell cycle check proteins p21 and p27, block the cell cycle, reduce the transcription of cyclin D1, and accelerate the degradation of c-Myc . Therefore, c-Met inhibitors and HDAC inhibitors have a certain synergistic effect on the mechanism of ...
