Abstract:
Phlojodicarpus sibiricus, a valuable endangered medicinal plant, is a source of angular pyranocoumarins used in pharmacology. Due to limited resource availability, other pyranocoumarin sources are needed. In the present research, the chemical composition of a closely related species, Phlojodicarpus villosus, was studied, along with P. sibiricus. High-performance liquid chromatography and mass-spectrometric analyses, followed by antibacterial activity studies of root extracts from both species, were performed. P. sibiricus and P. villosus differed significantly in coumarin composition. Pyranoco

Abstract:
This study explores the synthesis of a diverse series of linear (spiro)pyranocoumarins and their corresponding oximes, compounds known for their promising biological activities. Building on previous work, the authors expand the array of target compounds, adding structural features such as dimethyl groups and various cycloaliphatic rings. The novel synthetic procedure applied herein couples o-hydroxyacetyl coumarins with respective ketones via Kabbe condensation, yielding 16 derivatives, including 12 new compounds. A further step engages these (spiro)pyranocoumarins with hydroxylamine hydrochlo

Abstract:
This overview article contains information about pyranocoumarins over the last 55 years. The article is based on the authors’ phytochemical and physiological studies in vivo and in vitro as well as search and analysis of data in literature available on Google Scholar, Web of Science, PubMed, and ScienceDirect before January 2022. Pyranocoumarins are synthesized in plants of the Apiaceae, Rutaceae families, and one species in each of the Cornaceae, Calophyllaceae, and Fabaceae families can synthesize this class of compounds. The physiological role of these compounds in plants is not clear. It h

Abstract:
New pyranocoumarin and coumarin-sulfonamide derivatives were prepared and evaluated for their antioxidant, antimicrobial, and/or anti-inflammatory activities. Coumarin-sulfonamide compounds 8a–d demonstrated significant antioxidant activity, while 7c,d, 8c,d, and 9c,d exhibited antimicrobial activity equal to or higher than the standard antimicrobials against at least one tested microorganism. Regarding the anti-inflammatory testing, pyranocoumarins 2b, 3a,b and 5c and coumarin-sulfonamide compound 9a showed more potent antiproteinase activity than aspirin in vitro; however, five compounds wer

Abstract:
This study investigated the extraction and quantification of specific phenolic compounds, including chlorogenic acid and several pyranocoumarin derivatives, from the leaves and roots of Peucedanum japonicum. Using high-performance liquid chromatography, this study aimed to optimize extraction methodologies with different solvents to maximize the yield of bioactive compounds. The extraction process involved meticulous steps, including reflux extraction and solvent evaporation, and the total phenolic content was assessed using a spectrophotometric assay. The results demonstrated that ethanol and

Abstract:
Pyrano- and dipyranocoumarins are classes of naturally occurring organic compounds with very interesting biological activities. This review focuses on the synthetic strategies for the synthesis of pyranocoumarins and dipyranocoumarins and the biological properties of those compounds. The synthesis involves the formation of the pyran ring, at first, from a coumarin or the formation of pyranone moiety from an existing pyran. Pyranocoumarins and dipyranocoumarins present anti-HIV, anti-cancer, neuroprotective, antidiabetic, antibacterial, antifungal, anti-inflammatory activities. Especially khell
