Analogues and derivatives of nucleic acid components have been used as key drugs in different areas of medicine over the past decades. The replacement of one or more nitrogen atoms of the heterocyclic base with a CH group affords deazapurine nucleoside analogues, and the replacement of the methine group with a nitrogen atom gives azapurine derivatives. A combination of aza and deaza moieties in the purine base leads to aza(deaza)-modified bases. Some nucleoside analogues were found to exhibit pronounced anticancer and antiviral activity. The synthesis and evaluation of biological activity of aza- and deazapurine nucleoside analogues have attracted interest from researchers four decades ago. This review describes and integrates the studies concerning certain aspects of the synthesis and(or) activity of various representatives of this class of compounds. The structure–biological activity relationships are analyzed. The successful approaches to the design of aza- and deazapurine nucleoside analogues are considered. A comparison is given for the methods of chemical and enzymatic synthesis of these compounds. The bibliography includes 161 references.

Pickering emulsions are emulsions that are stabilized by solid micro- and nanoparticles. These emulsions are in most demand for applications where the use of surfactants is restricted. The review addresses stabilization of Pickering emulsions. The attention is focused on the flocculation, coalescence, sedimentation and Ostwald ripening processes taking place in these emulsions. The structures formed by particles in the emulsion dispersion medium and in thin interlayers between the dispersed phase droplets are analyzed. Methods for preparing colloidosomes, that is, microcapsules of assembled particles, from Pickering emulsions are considered. Colloidosomes are promising for the encapsulation and prolonged release of active substances. Conversely, Pickering stimuli-responsive emulsions provide intense release of encapsulated substances upon the change in the environmental parameters. This can be used not only in medicine and pharmacology, but also in sensors, food industry, paint and varnish industry, petroleum production, etc. The bibliography includes 340 references.

Ionic liquids (ILs) are considered as an alternative to conventional organic solvents used in industry, and the distinctive physical and chemical properties of these substances are being actively investigated. Ionic liquids can be applied in a number of areas, including polymerization reactions, catalysis and biomedicine. Although the overwhelming majority of studies are focused on the liquid state of ILs, an understanding of their properties in a glassy state can stimulate innovations in organic synthesis, energy storage and cryopreservation. This review aims at a systematic description of the properties and applications of ILs in the glassy state, which has not been published previously and appears relevant and demanded by the scientific community. The bibliography includes 286 references.

The review is devoted to extraction solvents of new generation, so called combined solvents, which include ionic liquids, aqueous biphasic systems and eutectic solvents. Most of modern combined solvents are based on organic ionic components. These solvents are associated with high expectations as they are able to provide the environmental safety and green character of extraction, which are priority tasks for the development of chemistry and chemical engineering. For all classes, an overview and a brief history of research are presented; details of structure and properties are discussed; various extraction systems are compared; and typical examples of extraction of metal ions and organic compounds are given. The lack of uniform terminology and difficulties in interpreting the behaviour of some systems, especially eutectic solvents, are outlined. The advantages and drawbacks of new generation extraction solvents and relevant research tasks are summarized. The bibliography includes 408 references.

The rapid progress in the chemistry of carboranes and other polyhedral boron compounds makes the development of methods for the synthesis of their various functional derivatives a high priority. The formation of cyclic oxonium derivatives followed by the ring opening is one of the most efficient methods for the preparation of these compounds. This review addresses the data on the use of the nucleophilic ring opening of cyclic oxonium derivatives based on cobalt and iron bis(dicarbollides), which have been extensively studied in recent years. Reactions involving O-, N-, S-, P- and C-nucleophiles are considered as a route to the targeted synthesis of a wide range of organic boron derivatives, in particular various boron-containing biologically active compounds. Possible applications of the reaction products are discussed. The bibliography includes 197 references.

A comprehensive review of the methods for topological analysis of crystalline compounds as applied to the structures of coordination polymers is presented for the first time. The basic concepts of reticular chemistry, a new branch of science, which combines methods of synthetic chemistry with methods for topological design of polymer compounds, are considered. Reticular chemistry methods are illustrated with examples of the analysis and design of coordination polymers. The most complete classification of coordination polymers, which are similar in terms of various compositional and topological parameters, is given. This review describes and integrates information on the topological analysis tools, such as computer software and electronic databases. A special attention is paid to the application of topological methods in the machine analysis and the prediction of structures and properties of coordination polymers, in particular to the establishment of chemical composition–structure–property relationships and the development of knowledge bases and artificial intelligence systems. A procedure for the search for the general crystal-chemical features using automatic heuristic analysis of large sets of structural data is discussed. It is shown how this analysis can be used to determine the limits of applicability of reticular chemistry and the possibility of its extension to coordination polymers containing structurally, chemically and topologically complex building units with high conformational flexibility. Approaches of reticular chemistry are considered in detail in relation to the design of proton-conductive coordination polymers, which have received considerable attention in the past decade. The specific features of the topological structures of this class of compounds are described in a systematic way. The relationships between the chemical composition, structure and conductive properties of these compounds and the applicability of targeted design are discussed. The bibliography includes 303 references.

Arylation methods based on the generation and use of aryl radicals have been a rapidly growing field of research in recent years and currently represent a powerful strategy for carbon – carbon and carbon – heteroatom bond formation. The progress in this field is related to advances in the methods for generation of aryl radicals. The currently used aryl radical precursors include aryl halides, aryldiazonium and diaryliodonium salts, arylcarboxylic acids and their derivatives, arylboronic acids, arylhydrazines, organosulfur(II, VI) compounds and some other compounds. Aryl radicals are generated under mild conditions by single electron reduction or oxidation of precursors induced by conventional reagents, visible light or electric current. A crucial role in the development of the radical arylation methodology belongs to photoredox processes either catalyzed by transition metal complexes or organic dyes or proceeding without catalysts. Unlike the conventional transition metal-catalyzed arylation methods, radical arylation reactions proceed very often at room temperature and have high functional group tolerance. Without claiming to be exhaustive, this review covers the most important advances of the current decade in the generation and synthetic applications of (het)aryl radicals. Examples of reactions are given and mechanistic insights are highlighted. The bibliography includes 341 references.
