Diphenyl-Furanones and Diphenyl-Oxopyrrole Derivatives: From Analytical Reagents for Amino Groups to New Fluorochromes for Cytochemical Staining of Chromatin DNA and Chromosomes: Proposal for Intercalative Binding and Fluorescence Mechanism

Colorants, 2023
Diaryl-furanones are specific analytical reagents for the biochemical detection of primary amines by fluorescence techniques. Well-known reagents are fluorescamine (Fluram) and 2-methoxy-2,4-diphenyl-3(2H)-furanone (MDPF), yielding fluorescent products ...

Comprehensive Evaluation of Fructus Tsaoko, Seeds of Tsaoko Fructus and Ginger Made Seeds of Tsaoko Fructus Based on Drug-Like Compounds and Aroma Analysis. [PDF]

Food Sci Nutr
This study mainly consists of two parts. First, after screening for drug‐like metabolites via LC–MS and GC–MS, a comprehensive evaluation model was established using a principal component analysis‐based weighted scoring method, by which the drug‐likeness ranking of three samples was determined.

Reactions of 5-(4-methoxy-3-methylphenyl)-2(3H)-furanone with some electrophilic and nucleophilic reagents [PDF]

, 2017
5-(4-Methoxy-3-methylphenyl)-2(3H)-furanone was prepared and reacted with some nucleophilic and electrophilic reagents. The condensation of furanone with aromatic aldehydes or phthalic anhydride yielded the corresponding 3-arylidenefuranone derivatives ...

Exploration of Antifungal and Immunomodulatory Potentials of a Furanone Derivative to Rescue Disseminated Cryptococosis in Mice [PDF]

Scientific Reports, 2017
AbstractCryptococcus neoformans infection is quite complex with both host-pathogen interaction and host immune profile determining disease progress and therapeutic outcome. Hence in the present study, the potential utility of (E)-5-benzylidenedihydrofuran-2(3 H)-one (compound-6) was explored as an effective anticryptococcal compound with ...

2,5-Dimethoxy-2,5-dihydrofuran chemistry: a new approach to 2(5H)-furanone derivatives

, 2008
2,5-Dimethoxy-2,5-dihydrofuran is a synthetic equivalent of 2(5H)-furanone or 2-trimethylsilyloxyfuran, useful C(4) synthons in the preparation of 5-substituted-2(5H)-furanone derivatives. The reaction conditions adopted allow to obtain different classes
