General description

9-Methylcarbazole is a nitrogen-containing polycyclic aromatic hydrocarbon. Claisen-Schmidt condensation of 3-formyl-9-methylcarbazole with various amides of 3-aminoacetophenone yields N-{3-[3-(9-methyl-9H-carbazol-3-yl)-acryloyl]-phenyl}-benzamide/amide derivatives.

Application

9-Methylcarbazole was used in facile synthesis of an organic electric conducting nanowire.

1. As previously reported (Yang and Davis 1992), N-methylcarbazole (NMC) is converted to N-hydroxymethylcarbazole (NHMC), and 3-hydroxy-N-hydroxymethylcarbazole (3-OH-NHMC), two relatively stable carbinolamine metabolites by the fungus Cunninghamella echinulata (ATCC 9244). Decomposition of these two carbinolamines yields the corresponding dealkylated metabolites

N-methylcarbazole (NMC) is a procarcinogenic component of tobacco smoke particulate matter. It is metabolized by liver microsomes into some hydroxylated metabolites such as the potent mutagen N-hydroxymethylcarbazole (NHMC). Lung metabolism and toxicity of NMC is not known. Since the lung

The source of the oxygen atom in the product of the cytochrome P-450-catalyzed N-demethylation of N-methylcarbazole was determined by mass spectral analysis of the carbinolamine precursor of formaldehyde formed during incubation in oxygen 18-enriched medium. Initial experiments demonstrated that N-(hydroxymethyl)carbazole

N-Methycarbazole (NMC), a carcinogen and mutagen in tobacco smoke, was converted to two major metabolites by primary cultured rat hepatocytes as measured by high performance liquid chromatography (HPLC): N-hydroxymethylcarbazole (NHMC) and carbazole. These two metabolites had comparable retention times and

The formation of N-hydroxymethylcarbazole (NHMC), carbazole, 1-hydroxy-N-methylcarbazole, 2-hydroxy-N-methylcarbazole, and 3-hydroxy-N-methylcarbazole as products of mammalian liver microsomal metabolism of N-methylcarbazole (NMC) has been documented by several investigators. In previous studies in our laboratory, the fungus Cunninghamella echinulata (ATCC 9244) produced two
