Based on our contemporary studies on the structures of biologically active molecules, we focus our attention on the aliphatic chain and its conformation. That flexible spacer definitely influenced the balanced position of all pharmacophoric points in molecules of biological ligands. The one atomic linker and two or three atomic spacers with one heteroatom X =O, S, CH2, NH have been taken into account. The conformational preferences clearly depend on the heteroatom X. In the discussion, we utilize our own X-ray data, computation chemistry methods, population analysis, and statistical data from the Cambridge Structural Database (CSD).

Focusing on the literature progress since 2002, the present review explores the highly significant role that multicomponent reactions (MCRs) have played as a very important tool for expedite synthesis of a vast number of organic molecules, but also, highlights the fact that many of such molecules are biologically active or at least have been submitted to any biological screen. The selected papers covered in this review must meet two mandatory requirements: (1) the reported products should be obtained via a multicomponent reaction; (2) the reported products should be biologically actives or at least tested for any biological property. Given the diversity of synthetic approaches utilized in MCRs, the highly diverse nature of the biological activities evaluated for the synthesized compounds, and considering their huge structural variability, much of the reported data are organized into concise schemes and tables to facilitate comparison, and to underscore the key points of this review.

Three different approaches to constructing bio-sensing units based on double-stranded (ds) DNA molecules, capable of detecting various biologically active compounds, are considered. The first approach is based on the abnormal optical activity of the liquid-crystalline dispersion formed from ds DNA molecules, modified by relevant physical factors or treated with biologically active compounds. The second one is based on the abnormal optical activity of the liquid-crystalline dispersions formed first from the ds DNA and then treated with coloured biologically active compounds. The third one is based on the abnormal optical activity, specific to particles of the liquid-crystalline dispersions, where the neighbouring DNA molecules are crosslinked by artifical polymeric bridges. These approaches permit the detection of biologically relevant compounds of various origins.

Hypothesis/aims of study. Myometrial relaxation and contraction require synchronous cellular interactions. At present, it has been established that the coordination of myometrial contractile activity is carried out by a conduction system constructed from gap junctions with intercellular channels. There are no clinical data on inhibiting (nitric oxide synthase) and activating (connexin-43) factors of uterine contractile activity in the myometrium during pregnancy and parturition in the published literature. This study was undertaken to measure the expression levels of nitric oxide synthase, adhesion molecules CD51, CD61, and connexin-43 in the myometrium during pregnancy and parturition; and to assess the role of inhibitory and activating factors in the development of uterine contractile activity. Study design, materials and methods. An immunohistochemical study of myometrial biopsy specimens obtained from the lower uterus segment during cesarean section was performed in eight women with a full-term physiological pregnancy, in another eight individuals in the active phase of uncomplicated parturition, and in eight patients with uterine inertia. Integrins (CD51 and CD61 proteins) were used as markers of cell adhesion. Localization and the number of intercellular contacts were assessed by measuring the expression level of connexin-43, with the intensity of oxidative processes assessed by nitric oxide synthase activity. Results. In the myometrium, in the active phase of physiological parturition, a three-fold increase in the expression of activating (CD51, CD61, and connexin-43) factors of uterine contractile activity and a five-fold decrease in that of inhibitory (nitric oxide synthase) ones occur compared to those in full-term physiological pregnancy. Conclusion. In the pathogenesis of uterine inertia and resistance to labor induction, an important role is played by the decreased expression of adhesion molecules (CD51, CD61) and connexin-43 and the increased expression of nitric oxide synthase in the myometrium.

Azo compounds are a very unique class of chemical compounds, drawing considerations in scientific research. Azo compounds are studied as class of organic colorants which have at least a conjugated chromophore azo (-N=N-) group in fusion with one or more aromatic or heterocyclic ring system. Benzimidazole derivatives are privileged intermediates for the development of molecules of pharmaceutical or biological interest. Benzimidazole derivatives have gathered wide applications in diverse therapeutic areas such as antiulcer, anticancer agents, and anthelmintic species to name just a few. Although many azo derivatives of benzimidazole nucleus has been reported in literature but only few of them have been evaluated for their biological potencies. This review focuses primarily on those derivatives which are evaluated as anticancer, antibacterial, antifungal, antitubercular, and other medicinal agents. This review may be helpful for the investigators on the basis of substitution pattern on the nucleus with an objective to assist medicinal chemists for developing an SAR on azo benzimidazoles or similar compounds.

Novel hybrids, comprised of a biologically active protein molecule core, coated with a thin outer layer of porous metallic silver, were developed in our lab. By the conjugation of silver reducing polymer to the surface of soluble, molecular, biologically active protein molecules and subsequent addition of silver salt, electroless silver deposition, culminating in thin porous metallic coating, was directed to the surface of the protein molecules. The silver-protein hybrids thus obtained, presenting novel nanoparticles several nanometers in size, retained their solubility and biological activity.The silver coating combined with the retained biological activity of its protein core, paved the way to a series of biomedical applications of these hybrids including "wiring" of the active site of oxido-reductase enzyme to electrodes, imaging of the presence of targeted ligands displayed on cancer cell surface and antimicrobial enzymatically attenuated release of silver ions.In this presentation we shall overview the technology of protein-silver hybrid's fabrication and analytical applications of silver-glucose oxidase and silver-Avidin hybrids, followed by feasibility demonstration of using silver-glucose oxidase hybrid as novel antibacterial and antifungal agent.

Host-Guest complexation of octakis(diphenoxyphosphoryloxy)tetramethylcalix[4]resorcinarene CRA and 5,17-bis-(N-tolyliminomethyl)-25,27-dipropoxycalix[4]arene CA with bio relevant aromatic, pyridine and diterpenoid carboxylic acids in water-organic solution had been studied by the RP HPLC and molecular modelling methods. The stability constants KA (387-1914 М-1) of the supramolecular complexes had been determined. It was shown the Host-Guest interactions are depended on structure of the Host molecules and log P values of the Guests. The complexation is determined by the hydrogen bonds of the COOH group of the carboxylic acids with P=O oxygen atom of diphenoxyphosphoryl group of the calixresorcinarene CRA, and oxygen or nitrogen atoms located on the lower or the upper rim of the calixarene CA.

Various model approaches for describing the equilibrium complexation of aromatic biologically active compounds with fullerene C60 molecules are proposed. Equilibrium constants of complexation for structurally different biologically active compounds in the aquatic environment were obtained based on these approaches. Models of continuous and discrete aggregation of C60 molecules are proposed, taking into account the polydisperse nature of fullerene solutions. The model of continuous aggregation considers the sequential growth of aggregates upon addition of C60 fullerene monomers to the already existing aggregates, with the equilibrium self-association constant of fullerene KF being the same for all stages of aggregation. The discrete model takes into account the presence of separate stable aggregates and fractal type of the higher aggregates formation from C60 fullerene aggregates. It is achieved by using the simplest two-level hierarchy of clusters distribution in the fractal series 1-4-7-13, known from the literature data. The model of continuous aggregation represents the classical approach used throughout to describe the aggregation of small molecules, while the discrete aggregation model can only be applied to fullerenes. The results obtained in this study lead to the conclusion that fullerene C60 can form stable complexes with aromatic antitumor drugs, which open the possibility of using these substrates in the future in cancer therapy.

In aqueous media, biologically active substances are usually unstable, poorly soluble compounds with low bioavailability. Incorporation of these compounds into the structure of lipid-based lyotropic liquid crystalline phase or nanoparticles can increase their solubility and subsequent bioavailability. The aim of this review is to clarify the principle of self-assembly of lipidic amphiphilic molecules in the aqueous environment, to present lipid bicontinuous cubic and hexagonal phases and their current biological application.
