Dual application of chiral derivatives of xanthones in medicinal chemistry and liquid chromatography

Over several years, xanthone derivatives have been the core of several studies, essentially due their wide range of biological and pharmacological activities [1]. Recently, chiral derivatives of xanthones (CDXs) have come to arouse great interest considering enantioselectivity studies associated with biological activities [2,3] as well as selectors for chiral stationary phases (CSPs) in liquid chromatography (LC) [4,5]. From the perspective of Medicinal Chemistry, some CDXs synthetized by our group revealed interesting biological activities [2,3]. Besides the potential as new drugs, CDXs afford promising LC enantioresolution results [6]. In a continuation of our study, new enantiomerically pure CDXs were synthetized for biological activity evaluation as well as selectors for new CSPs, confirming that CDXs have important applications not only in the field of Medicinal Chemistry but also for analytical applications.
