Coumarins are compounds characterized by a benzopyrone structure resulting from the condensation of pyrone and benzene ring. They commonly found as secondary metabolites in various plants, microorganisms, sponges. These play crucial role defence mechanisms, extensive research has revealed numerous biological activities associated with these compounds. Coumarin its derivatives show significant potential candidates for new drugs due to their exceptional biocompatibility wide range activities, including antimicrobial, anticancer, antimitotic, antioxidant, anti-inflammatory, anticoagulant properties. Beyond medicinal applications, simple versatile scaffold structures coumarins have use fields such food production, agriculture, cosmetics, textiles. This review covers classification coumarin derivatives, well chemical synthesis methods. Furthermore, it delves into properties, diverse application areas coumarins.

ABSTRACT Rationale Gentiana urnula Harry Sm is a frequently utilized traditional Chinese medicine (TCM) with applications in the treatment of range ailments including jaundice, gastrointestinal ulcers, and influenza. Despite its widespread uses, there lack comprehensive researches on chemical composition. Methods This study integrated SIRIUS, quantitative structure‐retention relationship (QSRR), liquid chromatography high‐resolution mass spectrometry (LC‐HRMS) to identify compounds Sm. Results A total 213 were identified high confidence based retention time (t R ), MS 1 , MS/MS. Among compounds, 26 positively firstly More than 5000 classified Spatial distribution revealed similarities compound between roots stems, while differences observed leaves flowers. Conclusions lays foundation for further investigations into biological activity pharmacological mechanism

Abstract In this work, we reported the synthesis of a novel series isatin‐incorporated thiazolyl‐coumarin derivatives 4(a–h) by one‐pot three‐component reaction substituted isatin, thiosemicarbazide, and 3‐(2‐bromoacetyl) coumarin. The structures coumarin‐thiazole scaffolds were precisely established their IR, NMR, HRMS spectral data. UV–Vis absorption study target molecules was investigated in six different solvents. Geometrical optimization, molecular electrostatic potential regions, quantum chemical parameters assessed using density functional theory (DFT) to explore electronic properties derivatives. synthesized compounds screened for vitro antimycobacterial activity against Mycobacterium tuberculosis ; all exhibited excellent antitubercular efficacy with MIC ≤ 3.25 µg/mL; among them, 4c 4f most potent 1.56 µg/mL. Furthermore, silico docking analyses enoyl‐ACP reductase (InhA) enzyme conducted; ligands demonstrated favorable binding interactions within active site InhA enzyme.

Despite the widespread ortho-functionalization of cyclic diaryliodoniums in organic chemistry, corresponding meta-functionalization is less explored. Herein, we report a practical meta-selective activation hypervalent iodoniums for synthesis 4-amino coumarin derivatives broad functional group tolerance and environmentally friendly manner. The practicability this protocol was further highlighted by late-stage modification some common pharmaceuticals natural products.

Due to their remarkable biological and pharmacological activities such as antibacterial, antifungal, anticoagulant, antioxidant, anticancer, anti-inflammatory properties, synthesis of coumarins derivatives has attracted considerable attention in research development among both organic medicinal chemists. In this paper, we demonstrated for the first time a two-step tandem enzymatic coumarin bioamide through sustainable continuous-flow technology. Salicylaldehyde dimethyl malonate were firstly reacted obtain carboxylate methyl derivatives, which then with various biogenic amines at 50 °C about 40 min under catalysis lipase TL IM from Thermomyces lanuginosus reactors. Reaction parameters reaction solvent, catalyst type, reactant ratio, residence time, temperature comparative experiments traditional batch process studied. Ideal product yields (62.7–87.1%) obtained. Environmentally friendly methanol was applied medium. Substantially shorter times well significant increase yield obtained compared process. This innovative approach provides promising green, efficient rapid strategy pharmaceutical further on novel derivatives.
