**About the Special Issue Editors**

**Maria Elizabeth Tiritan** has a degree in chemistry and PhD in organic chemistry. Currently, she is Assistant Professor at the Faculty of Pharmacy of University of Porto and Team Leader of the Drug Research line at IINFACTS. Her current interests in research include exploiting new enantioselective analytical methods to quantify and identify metabolites in the biodegradation of chiral drugs in environmental matrices; synthesis of new chiral compounds for diverse biological activities, including potential antitumor and antimicrobial agents; as well as structure–activity–properties relationships. She is also involved in the design of new chiral selectors for enantiomeric separation by liquid chromatography and membranes. https://orcid.org/0000-0003-3320-730X; https://sigarra.up.pt/ffup/pt/func geral.formview?p codigo=481977; https://iinfacts.cespu.pt/.

**Madalena Pinto** is a retired Full Professor from the Faculty of Pharmacy (FFUP) and Researcher and Team Leader of the Group of Natural Products and Medicinal Chemistry at the Interdisciplinary Center for Marine and Environmental Research (CIIMAR) University of Porto, Portugal. Her research areas focus on medicinal chemistry, involving the synthesis and molecular modification of pharmacologically active compounds based on natural models of plant and marine sources, as well as the development of substances with antifouling activity. She has a special interest in chirality, namely in synthesis and bioenantioselectivity studies of chiral bioactive compounds, as well as studies of structure–activity–properties relationships; molecular recognition of artificial receptors as new chiral stationary phases for liquid chromatography is another area of interest.

**Carla Sofia Garcia Fernandes** is a researcher at the Research Center CIIMAR and Assistant Professor of Organic and Medicinal Chemistry in the Faculty of Pharmacy of the University of Porto, Portugal. She obtained her B.S. in pharmaceutical sciences at the University of Porto in 2002; M.S. in quality control - scientific area in drug substances and medicinal plants, from the same university in 2006; and her PhD in pharmaceutical and medicinal chemistry from the same university in 2012. Current research interests include design of chiral compounds with potential biological activity, development of synthetic methodologies for obtaining bioactive chiral compounds, studies of enantioselectivity and structure–activity relationships, synthesis of chiral stationary phases, analytical and preparative enantiomeric separation of diverse racemic mixtures by liquid chromatography and membranes, and chiral recognition mechanisms.
