応用分野
説明Nordihydroguaiaretic acid (NDGA) is a grayish-white crystalline compound that was widely used as an antioxidant in animal fats in the 1950s and 1960s. It possesses phenolic properties similar to gallates, including their advantages and disadvantages. Besides the isolation of natural material (resinous exudate of creosote bush), NDGA has also been chemically synthesized. As the result of unfavorable toxicological findings, NDGA is prohibited from use in the US. More specifically, NDGA is a potent lipoxygenase inhibitor which interferes with arachidonic acid metabolism. The compound also inhibits formyltetrahydrofolate synthetase, carbox- ylesterase,and,to a lesser extent, cyclooxygenase.
一般的な説明Nordihydroguaiaretic acid (NDGA) is used as an powerful antioxidant and potent scavenger of reactive oxygen species (ROS). NDGA is a phenolic lignan obtained from Larrea tridentata, that has been used in traditional medicine for the treatment of numerous diseases such as cancer, renal, cardiovascular, immunological, and neurological disorders, and even aging.
調製方法
製造方法Nordihydroguaiaretic acid is obtained by hydrodemethylation of dimethyl ether of guaiacolinic acid, a component of guaiac resin. It is also produced from desert plant, creosote bush (Larrea divaricata Cav. Or Corillea tridentate), which can be widely found in the border zone of southern of USA and northern of Mexico.
純化方法Crystallise the acid from dilute acetic acid. [Beilstein 6 IV 7771.]
