Description

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.
