Embodiment 1

[0060] Substrate peptide STTPGGTLFSTTPG (the sequence of the substrate peptide is shown in SEQIDNO: 1 in the sequence listing, referring to the mTOR kinase test method of PerkinElmer Company), the substrate peptide was synthesized by Jill Biochemical (Shanghai) Co., Ltd., and its N 5-carboxyfluorescein (5-FAM) labeling is carried out at the end to facilitate fluorescence detection and improve the sensitivity of detection. The peptide structure of the obtained substrate peptide is shown in formula II:

Abstract

The invention discloses application of a polyphenolic compound. The polyphenolic compound shown in formula I can be used for preparing an mTOR inhibitor, especially an mTORC1 inhibitor. The invention further discloses application of the polyphenolic compound in the preparation of medicine for preventing and / or treating cancer, metabolic disorder syndrome, neurodegenerative diseases or inflammation. The diseases include diseases which are prevented and / or treated by inhibiting the catalytic activity of the enzyme of mTORC1. Preferably, the diseases include cancer, metabolic disorder syndrome, neurodegenerative diseases or inflammation. The polyphenolic compound can effectively inhibit the catalytic activity of the enzyme of mTOR and is good in curative effect on the cancer, metabolic disorder syndrome, neurodegenerative diseases or inflammation.

Description

technical field [0001] The present invention relates to the application of a polyphenolic compound. Background technique [0002] Mammalian target of rapamycin (mTOR) is an atypical highly conserved serine / threonine protein kinase, also known as FK506-binding protein 12 (FKBP12)-binding protein of rapamycin complex (FRAP ), or the target protein of rapamycin and FKBP12 (RAFT), which belongs to the phosphoinositide kinase-related protein kinase family (Phosphatidylinositol3-kinase (PI3K)-likekinase (PIKK) superfamily of kinases). In cells, it exerts its physiological activity mainly by forming two protein complexes with different functions, mammalian target of rapamycin complex 1 (mTORC1) and mammalian target of rapamycin complex 2 (mTORC2). mTORC1 contains mTOR, Raptor, Deptor, PRAS40 and mLST8, while mTORC2 contains mTOR, Riptor, Deptor, Protor, mSin1 and mLST8. The main function of mTORC1 is to regulate protein synthesis and cell cycle progression, while mTORC2 plays an ...
