In the crystal structure of the title compound, C(21)H(15)BrNO(2) (+)·CF(3)SO(3) (-), the cations form inversion dimers through π-π inter-actions between the acridine ring systems. These dimers are further linked by C-H⋯π and C-Br⋯π inter-actions. The cations and anions are connected by multidirectional C-H⋯O and C-F⋯π inter-actions. The acridine and benzene ring systems are oriented at 10.8 (1...

An octathymidylate covalently linked via its 3'-end to an acridine derivative inhibited the cytopathic effect of Simian Virus SV40 on CV-1 cells in culture. Control experiments revealed that this effect was virus-specific and did not arise as a result of oligonucleotide degradation by nucleases. A photoactive probe was covalently attached to the 5'-end of the oligonucleotide-acridine conjugate....

Acridine dye binding by cells of Escherichia coli has been characterized in terms of a number of parameters. There is a temperature-dependent, readily reversible binding of acriflavine which occurs to a greater extent with acridine-sensitive mutants of E. coli K-12 than with wild-type E. coli B or K-12. There is an essentially irreversible internal binding of acriflavine which occurs when the c...

ABSTRACT: The interaction of two cationic dyes namely, acridine orange and pinacyanol chloride with an anionic polyelectrolyte, heparin, has been investigated by spectrophotometric method.The polymer induced metachromasy in the dyes resulting in the shift of the absorption maxima of the dyes towards shorter wavelengths. The stability of the complexes formed between acridine orange and heparin w...

In the title compound, C(23)H(20)NO(2) (+)·CF(3)SO(3) (-), the acridine ring system is oriented at a dihedral angle of 23.1 (1)° with respect to the benzene ring and the carboxyl group is twisted at an angle of 74.1 (1)° relative to the acridine skeleton. In the crystal, adjacent cations are linked through C-H⋯π inter-actions and neighboring cations and anions via weak C-H⋯O hydrogen bonds. The...

In the crystal structure of the title compound, C(21)H(15)BrNO(2) (+)·CF(3)SO(3) (-), adjacent cations are linked through C-Br⋯π and π-π contacts [centroid-centroid distance = 3.744 (2) Å], and neighbouring cations and anions via C-H⋯O, C-F⋯π and S-O⋯π inter-actions. The acridine and benzene ring systems are oriented at a dihedral angle of 18.7 (1)°. The carb-oxy group is twisted at an angle of...

In the crystal structure of the title compound, C(21)H(16)NO(2) (+)·CF(3)SO(3) (-)·H(2)O, the anions and the water mol-ecules are linked by O-H⋯O inter-actions, while the cations form inversion dimers through π-π inter-actions between acridine ring systems. These dimers are linked by C-H⋯O and C-F⋯π inter-actions to adjacent anions, and by C-H⋯π inter-actions to neighboring cations. The water m...

In the crystal structure of the title mol-ecular salt, C(21)H(15)FNO(2) (+)·CF(3)SO(3) (-)·H(2)O, the cations form inversion dimers through π-π inter-actions between the acridine ring systems. These dimers are linked via C-H⋯O and C-F⋯π inter-actions to adjacent anions, and by C-H⋯π and C-F⋯π inter-actions to neighbouring cations. The water mol-ecule links two sites of the cation by C-H⋯O inter...
