Three germacranolides, as well as five flavonoids, natural steroid and simple phenolic compounds, were isolated from the inflorescence of Stizolophus balsamita growing in Iran. The paper presents active compounds found for the first time in the inflorescence of this species. The flavonoids, simple phenolic compounds and natural steroids have been isolated for the first time in the genus Stizolophus. The MTT assay was employed to study in vitro cytotoxic effects of the taxifolin against human fibroblasts. We also evaluate the possible biological properties/cosmetic effects of Stizolophus balsamita extract and taxifolin on the human skin. Sixty healthy Caucasian adult females with no dermatological diseases were investigated. We evaluate the effects of S. balsamita extract and taxifolin on skin hydration and transepidermal water loss (TEWL). It was revealed that S. balsamita extract might decrease TEWL level and fixed the barrier function of the epidermis. The presence of bioactive phytochemical constituents in S. balsamita inflorescences makes them a valuable and safe source for creating new cosmetics and medicines.

The aim of the research was to establish efficient microclonal propagation conditions of endangered Crambe mitridatis plants in vitro and to study the possible effect of aseptic cultivation on biochemical composition (hydroxycinnamic acids, flavonoids, phenolic compounds) of plants. Methods. In vitro plant culture methods were applied. Seeds were used for aseptic culture initiation. Morphogenic potential of root, leaf and petiole explants was studied on Murashige-Skoog medium with addition of plant growth regulators. The content of biologically active compounds was measured using spectrometry in plants grown in aseptic conditions and in the greenhouse. Results. Morphogenic potential of root, leaf and petiole explants was studied and the highest regeneration frequency of plantlets was established for root explants (80 %), for petiole explants (50 %) and the lowest for leaf explants (20 %). It was found that plants cultivated in aseptic conditions have higher hydroxycinnamic acids, flavonoids and phenolic compounds compared to plants grown in vivo. Conclusions. It is advisable to multiply C. mitridatis plants in vitro via root and petiole explants. Aseptic cultivation contributes to synthesis of biologically active compounds (auxin synergists) in C. mitridatis plants.Keywords: in vitro culture, hydroxycinnamic acids, flavonoids, phenolic compounds, Crambe mіtridatis.

The pyrazoline ring is defined as a “privileged structure” in medicinal chemistry. A variety of pharmacological properties of pyrazolines is associated with the nature and position of various substituents, which is especially evident in diarylpyrazolines. Compounds with a chalcone fragment show a wide range of biological properties as well as high reactivity which is primarily due to the presence of an α, β-unsaturated carbonyl system. At the same time, bicyclic monoterpenoids deserve special attention as a source of a key structural block or as one of the pharmacophore components of biologically active molecules. A series of new diarylpyrazoline derivatives based on isobornylchalcones with different substitutes (MeO, Hal, NO2, N(Me)2) was synthesized. Antioxidant properties of the obtained compounds were comparatively evaluated using in vitro model Fe2+/ascorbate-initiated lipid peroxidation in the substrate containing brain lipids of laboratory mice. It was demonstrated that the combination of the electron-donating group in the para-position of ring B and OH-group in the ring A in the structure of chalcone fragment provides significant antioxidant activity of synthesized diarylpyrazoline derivatives.

Pale-flowered licorice (Glycyrrhiza pallidiflora Maxim.) is the pea family (Fabaceae) perennial herb. It is a Russian Far East endemic. Pale-flowered licorice refers to the false (not sweet) licorice section (Pseudoglycyrrhiza Krug.), which do not accumulate glycyrrhizin derivatives. The G. pallidiflora successful introduction has been carried out over the past 5 years in the “Apothecary garden” territory, FRC UUH SB RAS, Kemerovo. Phytochemical studies screening biologically active compounds main classes of the plant aerial part confirmed the presence of a complex of phenolic compounds. The content of catechin derivatives and condensed-type tannins - proanthocyanidins (PAC) data in G. pallidiflora herb were obtained for the first time. In different years of cultivation, licorice herb accumulates phenolic compounds - up to 2.83 ± 0.22% in terms of gallic acid, flavonoids - up to 2.44 ± 0.03% in terms of rutin and PAC in terms of cyanidine chloride - up to 2.61 ± 0.11%. It was found that the maximum content of the phenolic compounds and PAC sum was observed in the herb for 4 years development. The greatest number of flavonoids accumulates in the herb harvested in the 3rd year of cultivation. A positive significant linear relation was found between antioxidant activity (AOA) and the total phenolic compounds and PAC content (r≥0.98). Considering that BAC with IC values ≤ 50 μg / ml in the DPPH assay refer to active antioxidant’s licorice herb can be classified as a plant with high antioxidant potential. It was found that the iron chelating activity of the G. pallidiflora herb is in direct dependence (r≥0.94) on the content of flavonoids. The obtained results demonstrate the importance of further study of this plant as a source of BAC, including plant antioxidants.

The paper presents a review of the publications on the anticancerogenic activity of the biologically active component of propolis – caffeic acid phenethyl ester (CAPE). Literature data indicate numerous biological properties of CAPE, namely: antioxidant, anti-inflammatory, antiviral, immunostimulatory, anti-angiogenic and others. In numerous tests, both in vitro and in vivo, the significant activity of CAPE has been confirmed, including an action against HT-29 human colon adenoma cells, and five: human, murine and other tumor cell cultures. The authors also emphasize that CAPE supports the anticancerogenic effect of drugs, including doxorubicin and cisplatin, due to the reduction of cancer cell survival by 45% and 34%, respectively, compared to the above-mentioned drugs used alone. The conducted research indicates that the induction of apoptosis in cells, i.e. programmed cell death, can be mentioned among the main mechanisms of the anticancerogenic activity of CAPE.

Background: Snail mucus (SM) is secreted by the pedal gland of snails, and has a fibrous structure when it crawls upside down on the plane. It contains biologically active compounds that have medical functions, such as glycol acid, natural antibiotics, and glycoprotein. Methods: For this paper, we prepared fibers using electrospinning to simulate this natural fiber for the first time, and we can produce the nanofiber with mucus from a snail. The effects of dissolution time and the spun solution were also investigated. Result: The results show that biomimetic nanofibers with different diameters can be obtained using electrospinning. When the concentration of the spun liquid was increased from 6wt% to 8wt%, a fiber with about a 200 nm diameter can be obtained. Adjusting the concentration plays a crucial role in electrospinning.

Dietary phenolic compounds are considered as bioactive compounds that have effects in different chronic disorders related to oxidative stress, inflammation process, or aging. These compounds, coming from a wide range of natural sources, have shown a pleiotropic behavior on key proteins that act as regulators. In this sense, this review aims to compile information on the effect exerted by the phenolic compounds and their metabolites on the main metabolic pathways involved in energy metabolism, inflammatory response, aging and their relationship with the biological properties reported in high prevalence chronic diseases. Numerous in vitro and in vivo studies have demonstrated their pleiotropic molecular mechanisms of action and these findings raise the possibility that phenolic compounds have a wide variety of roles in different targets.

Nowadays, the high blood pressure is one of the main causes of death and cardiovascular diseases. Vasodilator drugs are frequently used to treat arterial hypertension. Experiments were undertaken to determine whether hydroalcoholic extracts obtained from leaves of field-grown Alpinia purpurata and A. zerumbet cultured in vitro under different plant growth regulators induce a vasodilator effect on Wistar rat mesenteric vascular bed pre-contracted with norepinephrine. Plant extracts were able to induce a long-lasting endothelium-dependent vasodilation. Efficiency on activity of A. purpurata reached 87% at concentration of 60 μg. The extract of A. zerumbet maintained in medium containing IAA, induced the relaxation (17.4%) at 90 μg, as compared to the control (MS0) that showed a better vasodilator effect (60%). These results are in agreement with the quantification of phenolic compounds in the extracts, which were 50% lower for those plants cultured in IAA. A. purpurata was assayed for the first time in relation to its vasodilator activity. This paper showed a strong probability of correlation between the pharmacological activities of A. purpurata with their content in phenolic compounds.
