Antimicrobial activity of carbazole derivatives

Experientia, 1982
Glycozoline and girinimbine isomers (IV andVII) were synthesized and their activity against 2 bacterial strains, viz.E. coli andS. aureus, and 2 fungal strains, viz.C. albicans andA. niger were studied. The hydroxy synthons (III) were also tested.

Assessing Carbazole Derivatives as Single-Electron Photoreductants

The Journal of Organic Chemistry, 2022
The electron-donating capabilities of carbazoles have stimulated interest in their use as photoinduced single-electron reductants. Due to the modularity of the carbazole, a further broadening and understanding of their reactivity could be achieved by manipulating the structure.

Distribution of carbazole derivatives in petroleum

Organic Geochemistry, 1984
Abstract Carbazole, its alkyl derivatives and higher benzologs have been selectively isolated from six different crude oils. In all samples, benzocarbazoles are major constituents of a series which may extend up to dibenzocarbazole derivatives. The distribution includes unsubstituted parent compounds and shows a maximum content of methyl and dimethyl

On the electrochemical fluorination of derivatives of morpholine, piperidine and carbazole

Journal of Fluorine Chemistry, 1991
Abstract Electrochemical fluorination (ECF) of α,ωdimorpholino- and dipiperidino-alkanes of different chain length (n = 1−6), of di- (methyl-piperidino)-alkanes, of morpholinocyclohexene and of N-alkyl-carbazoles gave the perfluoro-derivatives in yields up to 45 %.

Novel carbazole derivatives as NPY Y1 antagonists

Bioorganic & Medicinal Chemistry Letters, 2007
The synthesis of a series of carbazole derivatives and their SAR at the NPY Y1 receptor is described. Modulation of physicochemical properties by appropriate decoration led to the identification of a high-affinity NPY Y1 antagonist that shows high brain penetration and modest oral bioavailability.

Photophysical processes of some carbazole derivatives and benzimidazole derivatives

Chemical Physics Letters, 2006
The photophysical properties of N-(1-naphthyl)-carbazole (1-NACZ), N-(2-naphthyl)-carbazole (2-NACZ), N-(1-naphthyl)-benzimidazole (1-NABI) and N-(2-naphthyl)-benzimidazole (2-NABI) were studied. The emission wavelengths of 1-NACZ and 2-NACZ were very sensitive to the polarity of solvents.

[Antimycobacterial acting carbazole derivatives].

Archiv der Pharmazie, 1995
Carbazoles are synthesized and tested for antimycobacterial properties (M. tuberculosis H 37 Ra, Middlebrook-7H9-broth). The different antimycobacterial properties of diastereomeres are examined using compounds 32 and 33, those of a racemic compound and the (+)-enantiomer are tested with (+/-)-12/(+)-12 and (+/-)-5/(+)-5, respectively.

The detection of carbazole units and poly N-vinyl carbazole in copolymers derived from N-vinyl carbazole

European Polymer Journal, 1968
Abstract Carbazole units in copolymers can be cross-linked by reaction with a Lewis acid catalyst in methylene chloride. The reaction initially causes gel formation, followed by the development (with BF3. Et2O) of a characteristic blue colour. The blue product has been shown to be a cationic dye of the diaryl—methyl type, derived from the dye base ...
