Radicals play a major role as intermediates in many chemical reactions. They contribute to transformations in the atmosphere, living organisms, chemical synthesis, combustion and detonation amongst others. This comprehensive and conclusive book discusses all these aspects. N-centered Radicals deals with NOx and NCO, relatively stable radicals whose presence in the atmosphere influences the metabolism of living organisms. Also included are NHx, NCH and N3, important in radical studies, chemical synthesis, detonation and metabolism. Until now there has been no single volume bringing together all aspects of N-centered radical chemistry, from formation, to their chemistry in aqueous environments, biological systems and the atmosphere. N-centered Radicals is essential reading for researchers in organic, physical and environmental chemistry, biology and all others examining the effects of N-centered radicals.
β-Carboline and its derivatives have generated considerable interest in recent years for their versatile properties in chemistry and pharmacology. This is due to their ability to act as agonists to benzodiazepine receptors, hydroxy serotonin receptors, and intercalate into DNA, to inhibit CDK, Topisomerase, and monoamine oxidase enzymes. Their pharmacological properties include anxiolytic, hypnotic, anticonvulsant, antiviral, antiparasitic and antimicrobial attributes. This book provides a summary of methods for the synthesis of various natural products engineered with the diverse β-carboline scaffold and their biological evaluation.

The tenn "calixarenes," introduced in 1978 by D. Gutsche to describe the cyclic oligomers produced by condensation of p-substituted phenols with fonnaldehyde, is now universally accepted in the chemical community. The condensation of phenol with fonnaldehyde was studied in the last century by A. von Baeyer. Early in this century, L. Baekeland produced the first entirely synthetic polymers from phenol-fonnaldehyde condensates and the possibility that cyclic condensation products could be obtained from t-butylphenol, and fonnaldehyde was mentioned as early as in the beginning of the 1940's by A. Zinke. Despite their long history, the realisation that calixarenes may have very significant applications and uses in supramolecular chemistry is a relatively recent phenomenon. Calixarene chemistry, in contrast to their discovery, started slowly in the 1970's but rapidly gained momentum throughout the 1980's. Following C. Pedersens discovery of the crown ethers and the seminal developments of J. -M. Lehn and D. Cram with cryptands and spherands - all three honoured with the 1987 Nobel Chemistry Prize - the time was right for a surge of interest in research areas, frequently referred to as host-guest chemistry, receptor or supramolecular chemistry, and including important comparisons with biological processes and the development of new advanced materials. Now, the cyclic, bowl or basket-shaped calixarene molecules were looked on in a different light. Rather than "having developed from harmful by-products of phenoplasts manufacture" they were now seen as potentially valuable macrocyclic receptor molecules.
The volumes of this classic series, now referred to simply as "Zechmeister after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series inauguration in 1938. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists, and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.
The first chapter describes the oldest method of communication between living systems in Nature, the chemical language. Plants, due to their lack of mobility, have developed the most sophisticated way of chemical communication. Despite that many examples involve this chemical communication process - allelopathy, there is still a lack of information about specific allelochemicals released into the environment, their purpose, as well as in-depth studies on the chemistry underground. These findings are critical to gain a better understanding of the role of these compounds and open up a wide range of possibilities and applications, especially in agriculture and phytomedicine. The most relevant aspects regarding the chemical language of plants, namely, kind of allelochemicals have been investigated, as well as their releasing mechanisms and their purpose, are described in this chapter. The second chapter is focused on the natural products obtained from Hypericum L., a genus of the family Hypericaceae within the dicotyledones. Hypericum has been valued for its important biological and chemical properties and its use in the treatment of depression and as an antibacterial has been well documented in primary literature and ethnobotanical reports. The present contribution gives a comprehensive summary of the chemical constituents and biological effects of this genus. A comprehensive account of the chemical constituents including phloroglucinol derivatives, xanthones, dianthrones, and flavonoids is included. These compounds show a diverse range of biological activities that include antimicrobial, cytotoxic, antidepressant-like, and antinociceptive effects. The third chapter addresses microtubule stabilizers, which are a mainstay in the treatment of many solid cancers and are often used in combination with molecularly targeted anticancer agents and immunotherapeutics. The taccalonolides are a unique class of such microtubule stabilizers isolated from plants of Tacca species that circumvent clinically relevant mechanisms of drug resistance. Although initial reports suggested that the microtubule stabilizing activity of the taccalonolides is independent of direct tubulin binding, additional studies have found that potent C-22,23 epoxidated taccalonolides covalently bind the Aspartate 226 residue of -tubulin and that this interaction is critical for their microtubule stabilizing activity. Some taccalonolides have demonstrated in vivo antitumor efficacy in drug-resistant tumor models with exquisite potency and long-lasting antitumor efficacy as a result of their irreversible target engagement. The recent identification of a site on the taccalonolide scaffold that is amenable to modification has provided evidence of the specificity of the taccalonolide-tubulin interaction and the opportunity to further optimize the targeted delivery of the taccalonolides to further improve their anticancer efficacy and potential for clinical development.
