Investigating the binding of acridine, acridine orange, and acridine yellow G to humic acid through fluorescence quenching.
A fluorescence quenching method was used to determine the equilibrium binding constants for the association of acridine, acridine orange, and acridine yellow G to humic acid. The fluorescence of each polycyclic aromatic nitrogen heterocycle (PANH) was monitored as aliquots of humic acid were added, and a Stern-Volmer plot was produced in which the slope is the equilibrium constant of the bindin...
متن کاملMeasurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide
Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...
متن کاملReaction of carcinogens with acridine.
Only a very small number of the known substances is strongly carcinogenic. This indicates that carcinogenicity is linked to different qualities which all must be present to produce cancer. The various chemical reactions or qualities brought into relation with carcinogenicity reflect one or more of these factors. None of them seems to comprise all involved parameters. At the same time, none of t...
متن کاملSolvatochromic Spectral Investigations of Acridine
Optical absorption and fluorescence emission spectral studies of acridine in different solvents namely, carbon tetrachloride, dichloromethane, propan-2-ol, ethanol, methanol, acetonitrile, and N,Ndimenthyl formamide have been investigated. Oscillator strength and transition dipole moment of the acridine have been elucidated from the optical absorption measurement. The ratio of the excited state...
متن کاملAcridine 0.75-hydrate
The title compound, C(13)H(9)N·0.75H(2)O was obtained during a study of the polymorphic system of acridine, by slow evaporation from an ethanol-water solution. There are two acridine mol-ecules (indicated by I and II, respectively) and one and a half water mol-ecules in the asymmetric unit. The half-mol-ecule of water is located on a crystallographic twofold axis. The crystal structure is built...
