Biological Activity of Monoterpene-Based Scaffolds: A Natural Toolbox for Drug Discovery
(MDPI, 2025-03-27) Mołdoch, Jarosław; Agacka-Mołdoch, Monika; Jóźwiak, Grzegorz; Wojtunik-Kulesza, Karolina
One of the most common strategies used in drug design is the molecular scaffold approach, which combines traditional medicine based on natural active compounds derived from plants with modern synthetic drug development. Designing new compounds based on natural skeletons enables extensive modifications of both bioavailability and biological activity. An excellent example of a natural molecular scaffold is the monoterpenes group, which serves as a core structure for building more complex molecules by attaching various chemical groups. Their ability to interact with biological targets, combined with structural versatility, makes them promising molecular scaffolds in pharmaceutical research and green chemistry applications. This review paper focuses on selected monoterpenes (carvacrol, carvone, citral, menthol, menthone, β-pinene, thymol, and verbenone), which are frequently used as molecular scaffolds. The newly designed derivatives exhibit various biological activities, including anticancer, antibacterial, antiviral, neuroprotective, and many others.

The biological value of protein is mainly determined by its amino acid composition, and primarily depends on the optimal content of individual exogenous amino acids. The synthesis of these compounds in oat grain is influenced by genetic factors, habitat conditions and the agrotechnology used in cultivation. The aim of this study was to assess the influence of production technology (integrated, intensive) on the yield, content and amino acid profile of protein in the grain of hulled and naked oats. Field studies were conducted at the Agricultural Experimental Station Kępa—Pulawy, Osiny farm of IUNG—PIB (Poland) during two growing seasons (2019 and 2020). It was found that the total protein content of oat grain and its amino acid composition significantly depended on genotype and production technology. Naked oat grain was characterised by significantly higher protein content. The higher the intensity of production, the higher the content of total protein and exogenous and endogenous amino acids. Lysine was the amino acid that limited the biological value of protein in the grain of both oat cultivars. Its deficit was more frequent in grain from intensive production technology.
Asymmetric responses of soil dissolved organic carbon and dissolved organic nitrogen to warming: A meta-analysis
(Elsevier, 2025-02-25) Ren, Tianjing; Smreczak, Bożena; Ukalska-Jaruga, Aleksandra; Hassan, Waseem; Cai, Andong
Soil dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) play pivotal roles in regulating soil carbon and nitrogen cycles. The global effects of experimental warming on DOC and DON concentrations and their relationship (DOC:DON) remain uncertain. This study integrates a dataset containing 321 separate DOC and 187 DON independent experiments to address the magnitude and direction of warming’s impact on DOC and DON, as well as the key driving factors. Our results indicated that while warming did not significantly affect DOC concentrations, it led to a notable increase in DON concentrations (8.84%), consequently reducing DOC:DON ratio by 10.79%. Soil moisture emerged as the most influential factor (19.0%) driving DOC responses to warming, whereas soil nitrate nitrogen was the primary driver (33.2%) of DON responses to warming. Soil ammonium nitrogen exhibited a positive linear relationship with the DOC:DON ratio, while soil nitrate nitrogen responded negatively as the DOC:DON ratio increased. Our results revealed the complex responses of carbon and nitrogen cycles to warming, including their decoupling patterns. This finding highlights the sensitivity and adaptability of soil carbon and nitrogen cycles to experimental warming, uncovers that warming could disrupt the soil carbon and nitrogen balance, potentially affecting ecosystem stability and function.
Differential impacts of nitrogen addition on soil dissolved organic carbon in humid and non-humid regions: A global meta-analysis
(Elsevier, 2025-03-01) Ren, Tianjing; Smreczak, Bożena; Ukalska-Jaruga, Aleksandra; Li, Xiaojie; Hassa, Wassem; Cai, Andong
Soil dissolved organic carbon (DOC) is the most active carbon pool, providing essential carbon and energy to soil microorganisms while playing a crucial role in carbon sequestration, transport, and stabilization in soils. Nitrogen (N) addition, a key factor influencing terrestrial carbon cycling, can significantly alter soil DOC dynamics. However, the global patterns and underlying drivers of DOC responses to N addition, particularly across regions with varying aridity indices, remain unclear. This study analyzed 1132 paired observations from 103 independent studies to quantify the response pattern of DOC to N addition in humid (554 observations) and non-humid (574 observations) regions and identify the factors driving these effects. The findings revealed an asymmetrical effect of N addition on soil DOC between humid and non-humid regions, rather than on microbial biomass carbon (MBC) or soil organic carbon (SOC). Specifically, N addition significantly decreased soil DOC ( 2.49%) in humid regions, while it increased DOC (7.30%) in non-humid regions. The effect size of soil DOC decreased linearly with the ratio of MBC to SOC in humid regions but increased linearly in non-humid regions. In humid regions, soil DOC response was positively correlated with initial MBC and inversely correlated with initial soil pH, whereas the opposite trend was observed in non-humid regions. Seasonal precipitation variability was identified as a significant driver of soil DOC response, independent of temperature, soil properties, and N addition rates. Moreover, initial SOC content was the primary driving factor for soil DOC response in humid regions, while the N addition rates were the primary driver in non-humid regions. These findings have important implications for enhancing soil carbon pool management, improving global carbon models, and addressing climate change, particularly under varying climatic conditions.
The Effect of Newly Developed Microbial Biopreparations on the Chemical Composition of Strawberry (Fragaria × ananassa Duch.) Fruit Grown in an Organic Farming System
(MDPI, 2025) Nakielska, Małgorzata; Feledyn-Szewczyk, Beata; Berbeć, Adam Kleofas; Ukalska-Jaruga, Aleksandra; Frąc, Magdalena
Non-chemical methods of fertilisation and protection have been gaining importance in recent years. This trend is closely linked to current European Union (EU) agricultural policy and the growing consumer awareness of the impact of nutrition on health. Newly developed biopreparations have to be tested for their agricultural efficiency alongside a quality assessment of the resulting food. The aim of this study was to determine whether the use of newly developed microbially enriched fertilisers in organic strawberry cultivation had an effect on fruit chemical composition and heavy metal accumulation. In the research, five biopreparations (K2–K6 combinations) containing selected Bacillus strains and plant extracts were tested in 2021 and 2022 on three strawberry cultivars: ‘Honeoye’, 'Rumba’, and ‘Vibrant’. After the vegetation period, the collected fruit samples were frozen, freeze-dried, and subjected to chemical analyses to determine the total carbon and nitrogen content, as well as the concentration of microelements (Mn, Fe), macroelements (Na, Mg, K, Ca, P) and heavy metals (Cd, Pb, Cu, and Zn). The application of the tested biopreparations did not significantly impact the total carbon content of strawberry fruit. For most of the tested traits, cultivars reacted differently to the tested preparations. A higher total nitrogen content was found for treatments treated with biopreparations, especially for the ‘Vibrant’ cultivar—ranging from 15.2 g·kg−1 K2 (BacilRoots) to 16.3 g·kg−1 K3 (BacilRoots + BacilExtra) and K5 (BacilRoots + BacilExtra + BacilHumus)—being about 10–18% higher than on the control object (K1). The content of sodium, phosphorus, calcium, and magnesium did not change significantly under the influence of biopreparations. The use of the K3 and K5 treatment resulted in significantly lower iron contents when compared to those of the control (strawberries sprayed with water with no biopreparations added)—respectively, by 16.1% and 17.9%. ‘Vibrant’ treated with water (control treatment) showed the highest contents of iron, copper, and zinc when compared to those treated with biopreparations.
No exceedances of the permissible heavy metal content were found in the samples tested.
