Protocatechuic aldehyde is a phenolic aldehyde, a compound released from cork stoppers into wine.[1]

This molecule can be used as a precursor in the vanillin synthesis by biotransformation by cell cultures of Capsicum frutescens, a type of Chili pepper.[2] It is also found in the mushroom Phellinus linteus.[3]

Pharmacological effects

Protocatechuic aldehyde regulates G protein-coupled estrogen receptor-1 (GPER-1) and exhibits protective effects in endothelial dysfunction and atherosclerosis.[4]
