Abstract

The invention discloses a 3-aryl coumarin derivative as well as a preparation method and application thereof. The preparation method comprises the following steps of: carrying out tandem condensation-lactonization reaction on substituted phenylacetic acid and substituted 2-hydroxybenzaldehyde as raw materials in the presence of triethylamine and acetic anhydride, and after the reaction is finished, respectively and independently carrying out three post-treatment methods to obtain the 3-aryl coumarin derivative. The 3-aryl coumarin derivative provided by the invention has good affinity to SIRT3 protein, can up-regulate the deacetylase activity of the SIRT3 protein and reverse ISO (isoprenaline) stimulated and induced cardiac hypertrophy, and can be used for preparing anti-cardiovascular disease or anti-diabetes drugs.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry and pharmacy, and in particular relates to a 3-aryl coumarin derivative and its preparation method and application. Background technique [0002] Protein post-translational modification is the key to the regulation of protein function. Sirtuins (silent information regulartors, silent information regulators) protein family, as important sirtuins, play an important role in regulating genome stability, energy metabolism, and responding to cellular stress (Theranostics, 2020, 10(18) ,8315). Among the seven members of the Sirtuins family, SIRT3 (Silent Information Regulator 3) protein is a class of NAD-dependent deacetylase localized in mitochondria, and is widely expressed in mitochondria-rich organs such as kidney, heart, brain and liver , whose regulated acetylation modification is critical for maintaining mitochondrial homeostasis in these organs (Cell, 2010, 143(5), 802-812). [0003] Studies...
