The dissociation constant (pKa) of a drug is a key parameter in drug discovery and pharmaceutical formulation. The hydroxy substituent has a significant effect on the acidity of hydroxycinnamic acid. In this work, the acidic constants of coumaric acids are obtained experimentally by spectrophotometry ...
Structures of resveratrol and common coumarins with potential antidiabetic properties. The structural diversity of phenyl propanoids and other phenolic acids such as gallate derivatives also come from their ability to polymerize to form diverse complex molecules. When two units of phenyl propanoids are ...
