Description

N-(BENZOYL)-PHENYLALANINE COMPOUND, A PHARMACEUTICAL COMPOSITION CONTAINING SAME, AND A USE THEREOF The present invention claims the priority of an invention patent application filed in China on January 20, 2021, titled "N-(benzoyl)-phenylalanine compound, a pharmaceutical composition containing same, and a use thereof", with application number 202110075764.7. Technical Field The present invention relates to the field of pharmaceutical chemistry, and relates to a N-(benzoyl)-phenylalanine compound used as an <semantics>α4β7<annotation encoding="application / x-tex">\alpha 4\beta 7< / annotation>< / semantics> integrin antagonist, a pharmaceutical composition containing same as an active ingredient, and their uses for prevention and / or treatment of <semantics>α4β7<annotation encoding="application / x-tex">\alpha 4\beta 7< / annotation>< / semantics> integrin related diseases (such as autoimmune and inflammatory diseases). Technology Background Integrin is a member of integral protein family. It is a kind of heterodimer cell surface protein that generally exists on the surface of vertebrate cells and depends on Ca2+or Mg2+. It is used to mediate the mutual recognition and adhesion between cells and between cells and extracellular matrixes, and plays the role of connecting the external effects and the internal structure of cells. Integrin is a transmembrane heterodimer composed of two non-covalently bound transmembrane subunits (i.e. <semantics>α<annotation encoding="application / x-tex">\alpha< / annotation>< / semantics> and <semantics>β<annotation encoding="application / x-tex">\beta< / annotation>< / semantics>). The extracellular head can combine with extracellular matrix protein, and the intracellular tail can connect with actin. Both subunits of the integrin are glycosylated and bound together by a non-covalent bond. Currently, there are a total of 18 known <semantics>α<annotation encoding="application / x-tex">\alpha< / annotation>< / semantics> subunits and 8 known <semantics>β<annotation encoding="application / x-tex">\beta< / annotation>< / semantics> subunits. Among them, the <semantics>α4β7<annotation encoding="application / x-tex">\alpha 4\beta 7< / annotation>< / semantics> integrin is expressed on the surface of lymphocytes and recognizes the mucosal address in cell adhesion molecule-1 (MAdCAM-1) of the extracellular ligand, which is expressed in the high endothelial venules (HEV) of the intestinal mucosal venules and the gut-associated lymphoid tissues (GALT). α4β7 integrin control the transfer of lymphocytes to intestinal tissues and their retention in the intestine through their interaction with MAdCAM-1. Someone has proposed that inhibiting the interaction between integrin and its ligand is an effective method for treating various autoimmune and inflammatory diseases, and blocking the <semantics>α4β7<annotation encoding="application / x-tex">\alpha 4\beta 7< / annotation>< / semantics>-MAdCAM-1 interaction has shown therapeutic effects on inflammatory bowel diseases, such as Crohn's disease (CD) and ulcerative colitis (UC). Therefore, there is an urgent need to develop <semantics>α4β7<annotation encoding="application / x-tex">\alpha 4\beta 7< / annotation>< / semantics> integrin antagonists for the prevention and / or treatment of autoimmune and inflammatory diseases (especially inflammatory bowel diseases). Summary of the Invention The purpose of the present invention is to provide a N-(benzoyl)-phenylalanine compound with a novel structure, which has high selectivity and inhibitory activity on <semantics>α4β7<annotation encoding="application / x-tex">\alpha 4\beta 7< / annotation>< / semantics> integrin, and can be administered orally. In addition, the purpose of the present invention is to provide a pharmaceutical composition containing the aforementioned compound as an active ingredient for the drug. In addition, the purpose of the present invention is to provide the intended use of aforementioned compound or pharmaceutical composition for the prevention and / or treatment of <semantics>α4β7<annotation encoding="application / x-tex">\alpha 4\beta 7< / annotation>< / semantics> integrin related diseases (such as autoimmune and inflammatory diseases). Specifically, the aforementioned purposes of the present invention are achieved through the following solutions: [1] Compounds as shown in general formula (1) or pharmaceutically acceptable salts,

Unless otherwise specified, the terms "arylsulfonylamino" and "heteroarylsulfonylamino" used in this article refer to the aforementioned aryl or heteroaryl, namely -NH-S (=O)2-aryl (such as benzenesulfonylamino) and -NH-S(=O)2-heteroaryl (such as furan-2-sulfonylamino), which are sequentially connected to the parent molecule through sulfones and nitrogen atoms. Unless otherwise specified, the terms "arylaminosulfonyl" and "heteroarylaminosulfonyl" used in this article refer to the aforementioned aryl or heteroaryl, namely -S (=O)2-NH-aryl (such as phenylaminosulfonyl) and <semantics>−S(=O)2<annotation encoding="application / x-tex">-S(=O)_2< / annotation>< / semantics>-NH-heteroaryl (such as furan-2-ylaminosulfonyl), which are sequentially connected to the parent molecular through nitrogen atoms and sulfonyl. Unless otherwise specified, the term "independently" used in this article refers to at least two functional groups (or segments) with the same or similar value range that exist in the structure and can have the same or different meanings in specific situations. For example, if R1 and R2 are independently hydrogen, halogen, hydroxyl, cyano, alkyl or aryl, then when R1 is hydrogen, R2 can be hydrogen, halogen, hydroxyl, cyano, alkyl or aryl; similarly, when R2 is hydrogen, R1 can be hydrogen, halogen, hydroxyl, cyano, alkyl or aryl. Unless otherwise specified, the term "substitution" and its variant forms used in this article mean that one or more (such as 1, 2, 3 or 4) atoms or atomic clusters (such as hydrogen atoms) on the designated atoms are substituted by other equivalents, provided that the normal valence of the designated atoms or atomic clusters in the current situation is not exceeded and stable compounds can be formed. Unless otherwise specified, the connecting site of the substituent in this article can be any suitable position of the substituent.
