Previously, it was shown that B. subtilis B-8130 produce bactericides and biologically active substances while fermenting different phyto-substrates. The bacilli release somatostatin-like peptide during solid-state fermentation of beet pulp sugar, sea-buckthorn leaves and flax seeds. The growth of bacterial culture is accompanied by the formation of biofilm that encapsulates phyto-carriers. The combination of all above factors determines high biological activity of probiotics and their effects on digestion in animals. We tested the addition of 0.1% B. subtilis B-8130 fermented substrate to the pig ration. The experiments showed higher weight gain, lowered daily feed expenses and improved survival. We found substantial changes in morphology of the small intestine epithelial cells associated with intensive absorption of feed nutrients in pigs that were fed with fermented sea-buckthorn leaves. This suggests influence of probiotics on digestion mediated by hormonal system.

The rapid development pace of the pharmaceutical science constantly increases the demand for new kind of medicine featured with high biological activity and non-toxicity at the same time. Setting the aim to enlarge the amount of scientific findings in the domain of biologically active substances, 1,2,4-triazole and theophylline were used as the starting material. These compounds form the basis for the majority of drugs, such as diuretics, antifungal and antibacterial medicaments. The combination of heterocycles put under research demonstrate a repeated probability increase in the variety of activities. Therefore, the relevance of the following study is determined by valuable properties of these substances. Besides that, the presence of a hydrazide element accounts for a high probability level of antimicrobial, particularly anti-tuberculosis activity.  In order to identify optimal conditions for the synthesis and physicochemical property research, 2-((5-((theophylline-7'-yl)methyl)-4-R-4H-1,2,4-triazole-3-yl)thio) acetohydrazide ylidenderivatives were obtained. The process of production was carried out through long chain reactions, using the sodium salt of theophylline as a substrate. The conversion is well known being described in many papers. Hydrazide was taken as the starting compound. It was dissolved in water-alcoholic medium while separately, aldehyde was dissolved or mixed in ethyl alcohol as well. The resulting solutions were decanted. The precipitate formed immediately or after a certain period of time, which is likely due to the state of matter of the starting aldehyde. 10 compounds (light-yellow crystalline materials with sharp melting point) were synthesized after that. Their structures and physicochemical properties were confirmed with modern methods of analysis. It is established that the reaction proceeds rapidly with a yield of 77‒95% in water-alcoholic medium at a temperature of about 80 °C.

In our country, wormwood ragweed (Ambrosia artemisiifolia) may cause serious problems. Nearly 5 million hectares of agricultural area was infected with ragweed (Ambrosia artemisiifolia), which is believed useless weed. Allergological point of view, most problematic weeds adventive. However, many physiologically very beneficial compound also included, those with the effects have been known also by the Indians. On this basis, herbs can be thought of as ragweed. Our goal was to present that the ragweed contains antifungal active substances as well. In this paper we tested the biological activity of the extracts against Alternaria alternata F.00750 in vitro. We related based on our examination that ragweed contains biologically active agents, by which it is hampered the reproduction of the Alternaria alternata. The minimum effective concentration was 300 mg extract in a Petri dish, which was three days inhibited the growth of fungus. Full fungicidal effect was observed over dose 525 mg.

In the carried out of the research, Xylotroph macromycetes have been researched as a perspective producer of bıologıcal actıve substances used for various purposes today in world practice which spread in Azerbaijan and some of their features (the biological activity of synthesized metabolites, toxicity, antimicrobial activity and dynamics of biomass formation ). It became clear that fungi such as Ganoderma lucidum (Curtis) P. Karst., Laetiporus sulphureus (Bull.) Murrill, Pleurotus ostreatus (Jacq.) P. Kumm, Schyzophyllum commune Fr and Trametes versicolor (L.) Lloyd considered as a perspective producer of bıologıcal actıve substances is widely spread in the forests of Azerbaijan, and some of them are even dominant species of xylomicobiot inherent in the nature of Azerbaijan. As a result of studies with isolated strains of these fungi, it was shown that both in the culture solution (CS) and in the vegetative mycelia (VB), there are metabolites with biological activity. The result of research also became clear that antimicrobial activity of CS in all cases is higher than in water or alcohol extracts of dry biomass (1,1-1,2 times), although it defines the overall biological activity of VB extracts to the relationship of Paramecium caudatum gives a higher increase effect. In addition, the selected active strains do not lag behind the known strains in terms of the amount of biomass formed (up to 8.7 g/l in 7 days) and manifestations of forms of biological activity. This gives a serious basis to realize the production of biologically active substances for different (food, feed, medical and other) purposes on their basis.

Abstract Drone brood homogenate and compositions based on it are gaining popularity as functional food products and biologically active food additives. It has antioxidant, androgenic, anabolic, sedative, antidepressant, immunotropic, cosmetic and other properties. Royal jelly and drone brood have a pronounced biological activity, as they contain a large amount of decenoic acids, sulfhydryl groups, proteins, peptides and other biologically active substances. The possibility of expanding the spectrum of biological activity determines the relevance of developing a product containing a composition of drone brood and royal jelly. A significant superiority of the safety of biologically active substances in adsorbed drone brood and royal jelly in comparison with lyophilized ones was shown, which indicates the preferred method of stabilizing the combined product. The purpose of the work was to compare two technological methods for preparing a combined product. The first method consisted in the joint adsorption of royal jelly and drone brood, and the second - in separate adsorption and drying, followed by joint dry granulation of the components. It is shown that the differences in the physicochemical characteristics of products obtained by different methods are insignificant. The composition has intermediate values of physicochemical indicators between drone brood and royal jelly.

The synthesis of рolycyclic quinoid compounds, which exhibit a wide range of biological activity is one of the most promising and actively developing areas of the fine organic synthesis. Heterocyclic compounds including those that can be donors of nitrogen oxide NO occupy a special place among biologically active structures. These substances include a number of N-oxides, e.g., 1,2-diazet-1,2-dioxides, furoxanes and their benzo analogs, and N,N′-pyrazole dioxides. The reason for the high biological activity of N-oxides of nitrogenous heterocycles, which cannot easily generate nitrogen oxide NO may be their oxidative properties. Thus, N-oxides of nitrogenous heterocycles are of interest due to their high biological activity. We have developed an approach to the synthesis of 5-hydroxy-10-R-benzo[a]phenazine-12-oxides that contain the N-oxide fragment, which makes these compounds promising for studying their biological activity. We have demonstrated that the treatment of 2-arylamino-1,4-naphthoquinones with hydroxylamine in ethanol at 50-60 °С leads to selective oximation at position 1 and the formation of 2-arylamino-1,4-naphthoquinone-1-oximes. It has been shown that the interaction of 2-arylamino-1,4-naphthoquinone-1-oximes with the nitrating mixture in acetic acid results in the formation of 5-hydroxy-10-R-benzo[a]phenazine-12-oxides. Our work is a continuation of the study on the interactions of 2-arylamino-1,4-naphthoquinones and 4-arylamino-1,2-naphthoquinones with nitrosylsulfuric acid in acetic acid and the interaction of 2-alkyl(benzyl)amino-1,4-naphthoquinones with nitrosylsulfuric acid or nitrating mixture in acetic acid. The former reactions lead to the formation of 3-R-benzo[b]phenazine-6,11-dione-5-oxides and 9-R-benzo[a]phenazine-5,6-dion-7-oxides, respectively. The latter reaction leads to the formation of 2-alkyl(aryl)naphtho[2,1-d][1,3]oxazole-4,5-dione-4-oximes and 2-alkyl(aryl)-1-hydroxy-1H-naphtho[2,3-d]imidazole-4,9-dione as main products.
