Photoabsorption spectra of a natural polyphenol compound for therapeutic applications: the protocatechuic acid in dilute water solution at room temperature

The UV-Vis absorption spectra of the protocatechuic acid, a potential new drug for the treatment of cancerous tumors and central nervous diseases, is for the first time fully reproduced in water solution at room temperature; these results open up the routes to integrated experimental/simulated studies in order to identify characteristic spectroscopic features of such a molecule and its derivatives within different hosting receptors in nature.
