The therapeutic potential of gallic acid and its derivatives as anti-cancer, antimicrobial and antiviral agents is well known. We have examined the mechanism by which natural gallic acid and newly synthesized gallic acid alkyl esters and related protocatechuic acid alkyl esters inhibit HIV-1 protease to compare the influence of the aromatic ring substitutions on inhibition. We used Zhang-Poorman's

A series of alkyl gallates was synthesized by reacting gallic acid with the corresponding alcohols. Their structures were determined on the basis of spectroscopic data, including NMR and MS. The antifungal activities of these compounds against plant pathogenic fungi in vitro and in vivo were assessed.
通过没食子酸与相应的醇反应,合成了一系列没食子酸烷基酯。根据 NMR 和 MS 等光谱数据确定了这些化合物的结构。评估了这些化合物在体外和体内对植物病原真菌的抗真菌活性。
An efficient synthesis of alkyl gallates under microwave irradiation was described. The reaction took place in 6-10 mins, which was much shorter than the traditional synthetic methods, with almost quantitative yields.

In the present investigation, gallicacid was isolated from Alchornea glandulosa (Euphorbiaceae) and eight esters were synthesised. These compounds were evaluated against TNF-α-induced NFκB activation with stably transfected 293/NFκB-Luc human embryonic kidney cells. Gallates with IC 50 values in a range of 10–56 µM mediated inhibitory activity higher than gallicacid (IC 50 76.0 ± 4.9 µM). In addition
