Synthesis method of octadecyl gallate

The invention provides a synthesis method of octadecyl gallate. The synthesis method is characterized in that octadecyl gallate is obtained from gallic acid and octadecanol under the catalytic action of cation exchange resin 731 or cation exchange resin 7

Design, Synthesis, and Antifungal Activity of Alkyl Gallates Against Plant Pathogenic Fungi In Vitro and In Vivo

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.

Antiproliferative and apoptosis-inducing activities of alkyl gallate and gallamide derivatives related to (-)-epigallocatechin gallate

Green tea and (-)-epigallocatechin gallate (EGCG: one of the main components of green tea) are reported to have cancer-preventive activity in humans. A previous SAR study of EGCG and derivatives indicated that a galloyl group is essential for the activity. To test this hypothesis, we synthesized various alkyl gallate and gallamide derivatives and evaluated their antiproliferative effects on human leukemia HL-60 cells. Dodecyl 3,4,5-trihydroxybenzoate (6c) showed the most potent activity, being more potent than EGCG. To clarify the molecular mechanism of the antiproliferative action, we investigated the effects of 6c on various factors. Compound 6c was found to induce apoptosis mediated by endoplasmic reticulum (ER)-stress-related caspase-12. Upregulation of gadd-153, an ER-stress marker protein, was also observed. These results indicate that 6c induced apoptosis via the ER-stress-related pathway.

Evaluation of anti-herpetic and antioxidant activities, and cytotoxic and genotoxic effects of synthetic alkyl-esters of gallic acid

The n-alkyl esters of gallic acid (CAS 138-57-8) have a diverse range of uses as anti-oxidants in food, cosmetics and pharmaceutical industries. Pharmaceutical studies performed with these compounds have found that they have many therapeutic potentialities including anti-cancer, antiviral and antimicrobial properties. However, more interest has been devoted to their antioxidant activity due to the ability to scavenge and reduce reactive oxygen species (ROS) formation. In this study, gallic acid and 14 different alkyl gallates were tested. The cytotoxicity and anti-herpetic (HSV-1, KOS and 29-R strains) activity were studied by using the MTT (3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide) colorimetric assay and the cell viability by using the Trypan blue dye exclusion method. The genotoxicity was studied by the Comet assay and the antioxidant activity by using the DPPH (1,1-diphenyl-2- picrylhydrazyl) radical scavenging and microsomal lipid peroxidation-inhibiting activities. The results showed that all the tested compounds have anti-herpetic activity at non cytotoxic concentrations with selectivity indices (SI = CC 50/EC50) varying from 0.89 to 18.34, depending on the used HSV-1 strain. It was observed that all tested alkyl gallates showed some degree of genotoxicity, at the tested concentrations, except cetyl gallate, at 256.60 μmol/L (p 50 values varying from 17 to 31 μmol/L; and microsomal lipid peroxidation-inhibiting activity with IC50 values varying from 21 to 59 μmol/L. It was observed that the presence of hydroxyl groups in these molecules is important for their pharmacological profile, but the length of the lateral carbonic chain does not have considerable influence.
