Modulation of expression of endothelial nitric oxide synthase by nordihydroguaiaretic acid, a phenolic antioxidant in cultured endothelial cells

Retrospective epidemiological studies have suggested that antioxidant therapy may decrease cardiovascular morbidity and mortality rates, although the mechanisms for this effect remain unclear. In the present study, we demonstrate that selective antioxidan

Novel synthetic method of nordihydroguaiaretic acid (NDGA)

Nordihydroguaiaretic acid has wide physiological activity and pharmacological activity. The invention discloses a novel synthetic method of nordihydroguaiaretic acid, wherein the method comprises thefollowing steps: carrying out reductive coupling reaction on veratone serving as a raw material under the action of a catalyst to obtain pinacol; reducing pinacol by trialkylsilane or triarylsilane under the catalysis of protonic acid or Lewis acid to generate 1,4-bis(3,4-dimethoxyphenyl)-2,3-dimethylbutane; and finally, under the action of haloid acid or Lewis acid, breaking ether bonds, and synthesizing nordihydroguaiaretic acid. The structure of the compound is characterized by 1H-NMR. Raw materials and reagents used in the method are easy to obtain, the reaction route is short, the reaction conditions are mild, the yield is high, the cost is low, and a simple and convenient path is opened up for industrial synthesis of nordihydroguaiaretic acid.

Syntheses of (+/-)-Deoxyschizandrin and the Lignan, 1,4-Bis(3,4-dimethoxyphenyl)-2,3-dimethylbutane

(+/-)-Deoxyschizandrin (1) has been synthesised through a dimerisation reaction as a key step.The Grignard reagent from 1-(3,4,5-trimethoxyphenyl)-2-bromopropane (10) on reaction with 2-t-butyl-3-phenyloxaziridine gives 1,4-bis(3,4,5-trimethoxyphenyl)-2,3-dimethylbutane (11), which is cyclised using vanadium oxytrifluoride to get deoxyschizandrin (1).Following the above methodology, 1,4-bis(3,4-dimethoxyphenyl)-2,3-dimethylbutane (2), a lignan has also been prepared.
