General description

3-Hydroxy-4-methoxycinnamic acid, predominantly trans is available as white crystals. 3-Hydroxy-4-methoxycinnamic acid is isolated from the aerial part of Artemisia capillaris, Chinese medicinal plant. It is a component of chinese herbal medicine used for a pain killer and stomachic. It is an efficient acetylcholine inhibitor. 3-Hydroxy-4-methoxycinnamic acid is bioactive metabolite of Spilanthes acmella Murr. It increases the resistance of low-density lipoprotein (LDL) to oxidation.


3-Hydroxy-4-methoxycinnamic acid was used in the synthesis of tranilast and various tranilast analogs (cinnamoyl anthranilates) by genetically engineered Saccharomyces cerevisiae yeast strain. It was also used in the synthesis of glycoside compounds by undergoing glycosidation.

We investigated the mechanism(s) by which isoferulic acid lowers plasma glucose levels in streptozotocin-induced diabetic rats (STZ-diabetic rats). In STZ-diabetic rats, isoferulic acid dose dependently lowered plasma glucose concentrations and increased plasma beta-endorphin-like immunoreactivity (BER). Both of these effects of...
