Alkyl gallates showed elicitor activities on tobacco in both whole plants and cell suspensions. Methyl gallate (MG), ethyl gallate (EG), and propyl gallate (PG) infiltration into tobacco leaves induced hypersensitive reaction-like lesions and topical production of autofluorescent compounds revealed under UV light. When sprayed on tobacco plants at 5 mM, EG promoted upregulation of defense-related genes such as the antimicrobial PR1, β-1,3-glucanase PR2, Chitinase PR3, and osmotin PR5 target genes. Tobacco BY-2 cells challenged with EG underwent cell death in 48 h, which was significantly reduced in the presence of the protease inhibitor aprotinin. The three alkyl gallates all caused alkalinization of the BY-2 extracellular medium, whereas gallic acid did not trigger any pH variation. Using EGTA or LaCl3, we showed that Ca2+ mobilization occurred in BY-2 cells elicited with EG. Overall, our findings are the first evidence of alkyl gallate elicitor properties with early perception events on the plasma membrane, potential hypersensitive reactions, and PR-related downstream defense responses in tobacco.

The aim of this study was to investigate the bioactive constituents of Qingwen Baidu Decoction (QBD) in a rat model of acute lung injury (ALI) induced by lipopolysaccharide (LPS). Our previous studies showed that ethyl gallate (EG) and pentagalloylglucose (PGG) were the active components of QBD for the treatment of ALI.
MATERIALS AND METHODS:
We isolated two compounds and identified the structures of them by nuclear magnetic resonance and mass spectrometer. Lung injury was induced by intratracheal instillation with LPS (5 mg/kg). Rats were randomly divided into six groups: Control group; LPS group; 5 mL/kg DEX + LPS group; 6.6 g/kg QBD extract + LPS group; 17.16 mg/kg PGG + LPS group; 7.26 mg/kg EG + LPS group. The effects of compounds on LPS-induced the number of total cells, neutrophils influx, protein leakage, W/D weight ratio and pulmonary histological changes were examined.
The results demonstrated that pretreatment with EG and PGG could notably inhibit lung edema and attenuate the pulmonary histological changes (P<0.05). The pretreatment also decreased the number of total cells and polymorphonuclear leukocytes in bronchoalveolar lavage fluid (BALF) (P<0.05).
Ethyl gallate and pentagalloylglucose of QBD played a protective role in preventing LPS-induced ALI. The results supported further study of EG and PGG as potential candidates for preventing ALI.

In recent years, the exploration for potential inhibitors of HIV has been increased due to the development of drug resistant HIV strains in infected people undergoing antiretroviral agents treatment. In this report, we studied the anti-HIV properties of ethyl gallate (EG) against a panel of HIV-1 strains in in vitro conditions. Different clinical isolates and laboratory strains of HIV-1 were tested for their sensitivity with EG. We found that EG exhibited non-toxic nature over a wide range of cell lines from different tissue origin. Serum proteins have little to no impact on the antiviral activity of EG. In the present study, EG was found to be a promising anti-HIV agent.
