Description

Technical Field

[0001] The present invention belongs to the field of pharmaceutical chemistry, and specifically relates to an HDAC inhibitor and a preparation method and use thereof. Background Art

[0002] Histone acetylation is an epigenetic regulatory mechanism that is regulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs). When HDACs are overexpressed, DNA and chromatin are tightly bound, which is not conducive to the transcription of specific tumor suppressor genes and promotes the occurrence and development of cancer (Biochem. J. 2003, 370 (3): 737-749).

[0003] To date, a total of five HDAC pan-inhibitors have been approved for marketing, including the hydroxamic acid compound vorinostat (SAHA) for the treatment of cutaneous T-cell lymphoma and the hydroxamic acid compound panobinostat for the treatment of relapsed or refractory multiple myeloma. However, since the HDAC inhibitors that have been marketed can act on multiple subtypes of HDAC, nausea, vomiting, bone marrow suppression and other toxic side effects are common, and HDAC subtype selective inhibitors may avoid these adverse reactions. Therefore, the development and research of HDAC subtype selective inhibitors is of great significance. Structurally, HDAC inhibitors are usually composed of an enzyme surface recognition group (Cap), a linker fragment that fills the catalytic channel, and a zinc ion chelating group (ZBG), such as ACY-1215 and TUB-A.

[0004]

[0005] A large number of studies have shown that phenanthrene compounds have a variety of biological activities, including anti-tumor, anti-inflammatory, anti-malarial, anti-viral, anti-neurological diseases, etc. (J.Med.Chem.2012,55(23):10363-10377). Tylophorine is a phenanthroline alkaloid from Asclepiadaceae. Since it was first isolated from Rhizoma Cibotii, its pharmacological activity and synthesis method have been widely studied (Bioorg.Med.Chem.Lett.2017,27(11):2369-2376). This type of alkaloid not only has very strong anti-tumor activity, but also has good therapeutic effects in anti-inflammatory, anti-microbial and anti-leukemia. Antofine, as a typical phenanthroline alkaloid, has strong anti-cancer activity and has a strong inhibitory effect on the GI tract of A549 lung cancer cells. 50 The value is 0.01 μM. However, the targets of phenanthrene compounds are unclear, and the unknown off-target risks limit their further development.

[0006] The present invention combines the structural characteristics of HDAC inhibitors and the anti-tumor activity of phenanthrene compounds, uses phenanthrene ring derivatives as Cap units, covalently connects them to hydroxamic acid groups via Linkers, and constructs target molecules to provide a new type of selective HDAC inhibitors. Summary of the invention

[0007] In order to overcome the deficiencies of the prior art, the present invention provides an HDAC inhibitor and a preparation method and use thereof. In one aspect, the present invention provides a compound represented by formula (I):

[0008]

[0009] or stereoisomers, tautomers, solvates, prodrugs, isotope labels, and pharmaceutically acceptable salts thereof; wherein R1, R2, R3, A, B and D are as defined herein.

[0010] In another aspect, the present invention provides a pharmaceutical composition comprising a compound of formula (I) or a stereoisomer, tautomer, solvate, prodrug, isotope-labeled substance, pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier.

[0011] In another aspect, the present invention provides the use of the compound of formula (I) or its stereoisomers, tautomers, solvates, prodrugs, isotope labels, and pharmaceutically acceptable salts and / or pharmaceutical compositions containing the same in the preparation of drugs for preventing and / or treating cancer-related diseases.

[0012] Beneficial effects: Compared with the prior art, the compounds of the present invention not only have better selective HDAC (HDAC1 / HDAC6) inhibitory activity, but also can achieve good anti-tumor effects by inhibiting the invasion and metastasis of tumor cells and blocking the cell cycle.
