Chemistry and Material Sciences naturally depend greatly on Synthesis as the initial stage for the existence of compounds and materials with desired behaviors, within the overall streamline of Design/Synthesis — Properties — Application/Function, and their relations. Such a general approach is of a too wide scope to be properly treated in a single set of publications, but this one on'Synthesis and Applications in Chemistry and Materials'restricts itself by aiming to show the strength and international character of the current research in synthetic chemistry that is being developed in Portugal or abroad by teams that cooperate with this country. Hence, it gathers representative contributions of main Portuguese research groups and foreign collaborating ones. Nevertheless, the topic should be understood in a wide sense, being open to types of studies with significance on sustainable synthesis and applications in chemistry, materials and/or related sciences.

Natural phenolics are powerful bioactive compounds, but their use as antioxidant agents in lipid-based foodstuffs and cosmetics is limited due to their hydrophilic traits. A promising technique to overcome low solubility of phenolics is to increase their hydrophobicity by grafting with lipophilic moiety to form lipid-enriched phenolics (lipo-phenolics). Another way to enhance the amphiphilic traits of phenolics is by lipophilization with phospholipids in a suitable solvent to form phenolics-enriched phospholipids (pheno-phospholipids). Both functionalized phenolics (phenolipids) exhibit high bioavailability and antioxidative potential. Functional phenolics-enriched phospholipids (pheno-phospholipids) play an important role in enhancing the functional properties of both phenolic compounds and phospholipids in food for their use in nutrition and health. Phenolipids have also found applications on an industrial scale, likely due to low costs, the availability of starting materialand safety. Recent advances in the field of lipophilization allow accessing molecules with high potency and targeted action covering a wide spectrum of bioactivities. Owing to their cost and availability, phenolipids find applications in niche sectors such as cosmetics and pharmaceutics as well as in the novel food. This book reports on the chemistry, preparation, and functionality of lipid-enriched phenolics (lipo-phenolics), broadening their applications in food, pharmaceuticals and cosmetics. The strategies of the lipophilization of phenolics, the effect of modification on the biological properties and potential applications of the resulting lipo-phenolics are reviewed. The text also discusses the preparation, physicochemical characteristics and functional properties of phenolipids and phytosomes, including the latest developments and their current industrial status.

Translational medicine addresses the gap between research and the clinical application of new discoveries. To efficiently deliver new drugs to care centers, a preclinical evaluation, both in vitro and in vivo, is required to ensure that the most active and least toxic compounds are selected as well as to predict clinical outcome. Antimicrobial nanomedicines have been shown to have higher specificity in their therapeutic targets and the ability to serve as adjuvants, increasing the effectiveness of pre-existing immune compounds. The design and development of new standardized protocols for evaluating antimicrobial nanomedicines is needed for both the industry and clinical laboratory. These protocols must aim to evaluate laboratory activity and present models of pharmacokinetic-pharmacodynamic and toxicokinetic behavior that predict absorption and distribution. Likewise, these protocols must follow a theranostics approach, be able to detect promising formulations, diagnose the infectious disease, and determine the correct treatment to implement a personalized therapeutic behavior. Given the possibilities that nanotechnology offers, not updating to new screening platforms is inadequate as it prevents the correct application of discoveries, increasing the effect of the valley of death between innovations and their use. This book is structured to discuss the fundamentals taken into account for the design of robust, reproducible and automatable evaluation platforms. These vital platforms should enable the discovery of new medicines with which to face antimicrobial resistance (RAM), one of the great problems of our time.

Early anthropological evidence for plant use as medicine is 60,000 years old as reported from the Neanderthal grave in Iraq. The importance of plants as medicine is further supported by archeological evidence from Asia and the Middle East. Today, around 1.4 billion people in South Asia alone have no access to modern health care, and rely instead on traditional medicine to alleviate various symptoms. On a global basis, approximately 50 to 80 thousand plant species are used either natively or as pharmaceutical derivatives for life-threatening conditions that include diabetes, hypertension and cancers. As the demand for plant-based medicine rises, there is an unmet need to investigate the quality, safety and efficacy of these herbals by the “scientific methods”. Current research on drug discovery from medicinal plants involves a multifaceted approach combining botanical, phytochemical, analytical, and molecular techniques. For instance, high throughput robotic screens have been developed by industry; it is now possible to carry out 50,000 tests per day in the search for compounds, which act on a key enzyme or a subset of receptors. This and other bioassays thus offer hope that one may eventually identify compounds for treating a variety of diseases or conditions. However, drug development from natural products is not without its problems. Frequent challenges encountered include the procurement of raw materials, the selection and implementation of appropriate high-throughput bioassays, and the scaling-up of preparative procedures. Research scientists should therefore arm themselves with the right tools and knowledge in order to harness the vast potentials of plant-based therapeutics. The main objective of Plant and Human Health is to serve as a comprehensive guide for this endeavor. Volume 1 highlights how humans from specific areas or cultures use indigenous plants. Despite technological developments, herbal drugs still occupy a preferential place in a majority of the population in the third world and have slowly taken roots as alternative medicine in the West. The integration of modern science with traditional uses of herbal drugs is important for our understanding of this ethnobotanical relationship. Volume 2 deals with the phytochemical and molecular characterization of herbal medicine. Specifically, it focuess on the secondary metabolic compounds, which afford protection against diseases. Lastly, Volume 3 discusses the physiological mechanisms by which the active ingredients of medicinal plants serve to improve human health. Together this three-volume collection intends to bridge the gap for herbalists, traditional and modern medical practitioners, and students and researchers in botany and horticulture.

This book investigates the main vegetable biomass types, their chemical characteristics and their potential to replace oil as raw material for the chemical industry, according to the principles of green chemistry. Authors from different scientific and technical backgrounds, from industry and academia, give an overview of the state of the art and ongoing developments. Aspects including bioeconomy, biorefineries, renewable chemistry and sustainability are also considered, given their relevance in this context. Furthermore, the book reviews green chemistry principles and their relation to biomass, while also exploring the main processes for converting biomass into bioproducts. The need to develop renewable feedstock for the chemical industry to replace oil has been identified as a major strategic challenge for the 21st century. In this context, the use of different types of vegetable biomass – starch, lignocellulosic, oleaginous, saccharide and algae – can be seenas a viable alternative to the use of non-renewable, more expensive raw materials. Furthermore, it offers a model for adding economic value to the agro industrial chains such as soybean, sugarcane, corn and forests, among others. This will in turn contribute to the sustainability of a wide range of chemicals, mainly organics and their transformation processes, which are widely used by modern society.
