Life cycle assessment of chemical synthesis of genistein and its glucosyl derivatives to be employed in the modulation of angiogenesis of hepatocellular cancer

Abstract

This work is focused on the application of Life Cycle Assessment (LCA) methodology for the quantification of the potential environmental impacts associated to the obtainment of three glucosyl derivatives of genistein. Genistein is known to possess the ability in vitro to contribute to control signaling of some molecules like Angiopoietin-2 that has a key role in angiogenesis and fibrosis from which Hepatocellular cancer can arise. Therefore, a fine tuning of genistein uptake and bioavailability (e.g., through glycosylation) may provide innovative anti-angiogenic therapies with benefits for cancer chemoprevention and treatment.The production of pharmaceutical quality genistein, from which the derivatives are obtained, was modelled considering a recently optimized published procedure. The preparation of 7-O-(β-D-glucosyl)genistein (or genistin) was experimentally conducted by exploiting a two-step synthetic protocol. During the work-up procedure, two further derivatives were isolated.In order to also comprise the potential human health benefits of the synthesized compounds, this work also proposes for the first time a potential damage assessment factor for genistein and its derivatives.
