Abstract

In the present work, the in vitro anti-proliferative and anti-bacterial activities of three semi-synthetic benzoate pinocembrin derivatives, isolated from the aerial parts of Glycyrrhiza glabra L., were investigated. As occurs in most natural compounds, the bioavailability of pinocembrin is very poor, therefore it should be improved by chemical strategies aimed to prolong its shelf life and, consequently, its activity. On this basis, three benzoate derivatives of pinocembrin (a1–a3) were synthesised and assayed in order to ascertain their biological value. Among them, compound a1 showed the highest anti-proliferative activity on a wide panel of cancer cell lines, as well as low toxic effects on non-malignant breast cells. The calculated IC50 values in HeLa and SKBR3 cells were 8.5 and 12.7 mM, respectively. Briefly, a1 treatment increased ROS levels, induced mitochondrial membrane damage leading to necrotic death of HeLa cells. Moreover, a1 displayed a promising anti-bacterial activity
