产品介绍

描述

熊果酸(UA)是一种羟基五环三萜酸(HPTA),具有抗菌、 抗癌、 抗氧化和抗炎作用。它还可以促进周围神经损伤后的神经再生。UA可以激活GABA能神经递质系统,从而延长睡眠持续时间。[GABA= γ-氨基丁酸]


应用

熊果酸可作为起始材料,用于与氯乙酸乙酯反应合成熊果酸乙氧甲酰基甲酯(ECU)。ECU可作为关键中间体,用于全合成重要的生物化合物3-乙酰基-2-[(未)取代苯基]-2,3-二氢-1,3,4-噁二唑-5-甲酯 3-O-乙酰基熊果酸。熊果酸也可用于制备新型杂环衍生物,以便进行各种活性研究。

Description

Ursolic acid (UA) is a hydroxyl pentacyclic triterpenoic acid (HPTA), which exhibits anti-bacterial, anti-cancer, anti-oxidative and anti-inflammatory effects. It can also promote neuroregeneration after peripheral nerve injury. UA can enhance sleep duration by activating the GABAergic neurotransmitter system. [GABA= γ-aminobutyric acid]Ursolic acid can be used as a starting material to synthesize ethoxycarbonylmethyl ursolate (ECU) by reacting with ethyl chloroacetate. ECU is further used as a key intermediate in the total synthesis of a biologically important compound 3-acetyl-2-[(un)substituted phenyl]-2,3-dihydro-1,3,4-oxadiazol-5-Me 3-O-acetylursolate. Ursolic acid can also be used to prepare novel heterocyclic derivatives for various activity studies.
