Beskrivning: Phloroglucinol (phlo) is a phenol derivative that shows a cytoprotective effect from oxidative damage by enhancing the activity of cellular catalase. It can also be used to prepare synthetic analogs of A-type proanthocyanidins (PACs) such as 2,8-dioxabicyclo nonane derivatives by reacting with the corresponding flavylium salts. Phlo can react with benzaldehyde derivatives to form phloroglucinol-based microporous polymeric organic frameworks (phlo-POF) with potential applications in ion exchange and gas adsorption. Phloroglucinol is an antispasmodic and a derivative of phenol.

Beskrivning: 6-Aminofluorescein has been demonstrated to be useful fluorescent labeling reagent for fullerene-based liposome nanostructures termed 'buckysomes'. 6-aminofluorescein dissolved in 0,1 N NaOH can be quantified from a maximum absorbance at 490 nm. Decarboxylated 6-aminofluorescein dissolved 6 N HCl (prepare by constant boiling at 110 °C for 24 h) can be quantified from a maximum absorbance at 454 nm. Aldehyde groups are formed by oxidateive damage to proteins, which can be detected by conjugation to decarboxylated 6-aminofluorescein. 6-Aminofluorescein has been used to determine its ability to potentiate the antiviral activity of poly r (A-U).
