Provided are a method for manufacturing 3,4,5-tricaffeoylquinic acid, which can produce 3,4,5-tricaffeoylquinic acid with high efficiency by a simple operation in a short process using inexpensive raw materials, and intermediate compounds. The method for manufacturing 3,4,5-tricaffeoylquinic acid of the invention includes at least Step (1) of allowing a compound represented by Formula (1) or a compound represented by Formula (2) to react with a compound represented by Formula (4); and Step (2) of deprotecting the product obtained in Step (1), and producing 3,4,5-tricaffeoylquinic acid:
Recently, a novel lignan sevanol was isolated from the thyme plant Thymus armeniacus. During structure-functional elucidation it showed significant biological activity on ASIC3 acid sensing channels. Herein we describe the first synthesis of sevanol with a 3% overall yield. The construction of a dihydronaphthalene ring by oxidative dimerization of a protected dihydroxycinnamic acid ester in the presence

in good yields of the target products either as the carboxylic acid or the methyl ester form. Eight new compounds were evaluated for their ability to influence the feeding behaviour of the pea aphid Acyrthosiphon pisum. Artificial diet bioassays showed that two compounds are toxic (mortality and growth inhibition) at lower concentrations than the reference 3,5-dicaffeoyl quinic acid.
New conjugates 1–6 containing 5-dFCR and selected hydroxycinnamic acids were synthesized and tested in vitro against pancreatic cancer (PDAC) lines. The ADME properties and molecular docking to CES2 or human albumin were discussed.
