Reversed-phase thin-layer chromatography and reversed-phase high-performance liquid chromatography were used for lipophilicity determination of a library of 30 thiazole chalcones and aurones previously synthetized in our laboratory. The experimental lipophilicity data have been compared with theoretical lipophilicity parameters estimated by various computational methods. Good correlations between the experimental and calculated lipophilicity parameters have been found for both investigated classes of compounds. Correlations between the lipophilicity of the thiazole chalcones and aurones and their antiproliferative activity were discussed. The methodologies and data gathered in this study will contribute to the lipophilicity studies of chalcones and aurones derivatives, two important classes of compounds in medicinal chemistry.

Article Synopsis
- The study investigates the genes related to flavonoid synthesis, regulation, and transport in a plant species called Ilex asprella, identifying 28,478 differentially expressed genes (DEGs) across leaf, stem, and root tissues.
- A detailed analysis reveals specific patterns of gene expression for flavonoid pathways, indicating that different pathways are dominant in different plant tissues: roots are more active in stilbenes and anthocyanins, while leaves focus on flavonols, and stems are associated with isoflavones.
- The research highlights the presence of key regulatory genes and transporters in these pathways and notes the lack of certain genes necessary for producing specific flavonoids, providing insights valuable for medicinal

, an annual herb belonging to the Leguminosae family, is traditionally consumed as tea in the form of dried whole herbs or beans. To deepen our understanding of the chemical constituents of we isolated 16 compounds, categorised as flavone derivatives (-), including a novel compound nomameflavone A (), a chalcone derivative (), an aurone derivative (), a chromone derivative (), a juglone derivative (), anthraquinone derivatives (-), phenolic compounds (-), and sterol derivatives (, ). The structure of each compound was elucidated using NMR and MS.

Arginase, a difficult-to-target metalloenzyme, is implicated in a wide range of diseases, including cancer, infectious, and cardiovascular diseases. Despite the medical need, existing inhibitors have limited structural diversity, consisting predominantly of amino acids and their derivatives. The search for innovative arginase inhibitors has now extended to screening approaches.

Aurones are a minor subgroup of flavonoids. Unlike other subgroups such as chalcones, flavones, and isoflavones, aurones have not been extensively explored as pancreatic lipase inhibitors. In this work, we studied the pancreatic lipase inhibitory potency of synthetic aurone derivatives.
