| 外観 | 白色～黄色～黄赤色粉末～結晶 | | 説明 | Acacetin is an O-methylated flavone found in various plants. It is reported to demonstrate spasmolytic, antinociceptive, anti-inflammatory, and antioxidant activity in various research models. | | 化学的特性 | Yellow Solid | | 使用 | VEGF expression inhibitor and tumor angiogenesis. A flavonoid with antiaggregatory activity in human blood. | | 定義 | ChEBI: A monomethoxyflavone that is the 4'-methyl ether derivative of apigenin. | | Synthesis Reference(s) | Tetrahedron Letters, 31, p. 6497, 1990 DOI: 10.1016/S0040-4039(00)97100-4 | | 一般的な説明 | Acacetin belongs to the category of naturally occurring plant pigments called flavonoids found in vascular plants. It was first reported to be extracted from the leaves of Robinia pseuducacia. It has been used as an active component of traditional Chinese medicine Xuelianhua. | | Biochem/physiol Actions | Acacetin has been noted to exhibit anti-peroxidative, anti-inflammatory, and anti-plasmodial properties. It has been posited to prevent the proliferation of Hep G2 cells, thereby causing cell apoptosis and subsequent anti-cancer action. It has antiarrhythmic properties and can be used in the treatment of Atrial fibrillation. | | 酵素阻害剤 | This naturally occurring flavone (FW = 286.27 g/mol; CAS 480-44-4), also known as 5,7-dihydroxy-4’-methoxyflavone and 7-O-methylapigenin, and systematically named as 5,7-dihydroxy-2-(4-methoxyphenyl)-chromen-4- one, from the black locust Robinia pseudoacacia is the aglycon of linarin and acaciin and is biosynthesized by apigenin 4'-O-methyltransferase from S-adenosyl-methionine and 5,7,4’-trihydroxyflavone (apigenin), yielding Sadenosylhomocysteine and acacetin. The chemical synthesis of acacetin was accomplished by Robert Robinson, who was awarded the 1947 Nobel Prize in Chemistry for his work on alkaloids and organic synthesis. Target(s): glutathione S-transferase; xanthine oxidase, Ki = 0.11 μM; CYP1A; CYP1B1; glutathione-disulfide reductase; DNA topoisomerase I; [myosin light-chain] kinase; and protein-tyrosine kinase, or non-specific protein-tyrosine kinase. |
