Special Issue Information

Dear Colleagues,

Whether of natural or synthetic origin, antioxidants can protect cells and tissues from free-radical-mediated damage. Antioxidants can minimize food loss, act as preservatives in drug and herbal formulations, or act as health-promoting compounds. Indeed, oxidation and inflammation are strictly connected by means of pleiotropic and redundant pathways. Antioxidants can tackle inflammation-related diseases by limiting excessive cytokine-mediated inflammatory responses. In this Special Issue, we will focus on antioxidant design, synthesis, purification, characterization, mechanisms of action, and biological and toxicological activities through in vitro, ex vivo, and in vivo investigations into synthetic antioxidants and anti-inflammatory agents. Nanotechnology-based formulations and delivery systems for these compounds, to improve bioavailability and reduce toxicity or chemical instability, will be also considered. Finally, updates on pharmacological effects, therapeutic properties, and future options in these compounds are also welcome. New protocols to assess the efficacy of these compounds will, furthermore, be considered.

The Special Issue welcomes manuscripts (reviews or research articles) regarding any aspect of synthetic antioxidants in relation to their applications in nutrition, medicinal chemistry, pharmacology and pharmacy, and food chemistry and technology.

Monolignols represent pivotal alcohol-based constituents in lignin synthesis, playing indispensable roles in plant growth and development with profound implications for industries reliant on wood and paper. Monolignols and their derivates have multiple applications in several industries. Monolignols exhibit antioxidant activity due to their ability to donate hydrogen atoms or electrons to neutralize free radicals, thus preventing oxidative stress and damage to cells. Characterized by their alcohol functionalities, monolignols present three main forms: p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol. In nature, particularly in plants, monolignols with geometry (E) predominate over their Z counterparts. The methods for obtaining the three canonical monolignols, two less-common monolignols, and a monolignol analogue are addressed to present an overview of these phenol-based compounds, particularly from a synthetic standpoint. A SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis is used to explain the advantages and disadvantages of synthesizing monolignols, key alcohol-containing raw materials with enormous significance in both plant biology and industrial applications, using bench chemical methods. The uniqueness of this work is that it provides an overview of the synthetic pathways of monolignols to assist researchers in pharmaceutical and biological fields in selecting an appropriate procedure for the preparation of their lignin models. Moreover, we aim to inspire scientists, particularly chemists, to develop more sustainable synthetic protocols for monolignols. Full article
