Abstract
Methyl di- and tri-O-caffeoylquinates were synthesized by esterification of methyl quinate with di-O-acetylcaffeoyl chloride, following deprotection of the acetyl groups. Moreover, 4,5-di-O-caffeoylquinic acid was synthesized by esterification of quinide with di-O-acetylcaffeoyl chloride, followed by a hydrolysis of product quinide. These synthetic compounds were tested for their hepatoprotective activity on _D-galactosamine (_D-GalN)/tumor necrosis factor-α (TNF- α)-induced cell death in primary cultured mouse hepatocytes, which possessed significant hepatoprotective activity concentration-dependently. The activity was enhanced by the presence of caffeoyl group. On the other hand, they showed only weak antiproliferative activities against murine colon 26-L5 carcinoma, human HT-1080 fibrosarcoma, murine B16-BL6 melanoma, and human lung carcinoma A-549 cells.
