The title compound, C(23)H(18)N(2)O(4)S(2), contains a pyrrolo group fused onto the plane of an indole ring with phenyl-sulfonyl and p-toluene-sulfonyl groups bonded to the indole and pyrrolo rings. The angles between the mean planes of the pyrrolo-indole ring and the phenyl-sulfonyl and p-toluene-sulfonyl rings are 73.7 (6) and 80.6 (0)°, respectively. The dihedral angle between the mean plane...

Pathogenic strains of Xanthomonas campestris pv. glycines which cause hypertrophy of leaf cells of susceptible soybean cultivars and nonpathogenic strains which do not cause hypertrophy were compared for their ability to produce indole compounds, including the plant hormone indole-3-acetic acid (IAA) in liquid media with or without supplementation with l-tryptophan. Several additional strains o...

Anoxybacillus rupiensis Ir2 (JQ912240), thermophilic bacteria capable of utilizing aromatic hydrocarbon especially N-compounds that form part of petroleum components.In an attempt to investigate the ability of this bacterium to degrade quinoline and indole, the strain Ir2 was grown on these N-compounds separately as a sole source of carbon and nitrogen. Results showed that strain Ir2 was able t...

Recent interest in tryptophan metabolism has been stimulated by evidence that tryptophan is a precursor of nicotinic acid in mammals (1) as well as in Neurospora CTUSSU (2). The formation of kynurenine, kynurenic acid, and xanthurenic acid from tryptophan has been demonstrated by numerous experiments (3-5) and has been confirmed by isotope technique in the case of kynurenine and kynurenic acid ...

The crystal structures of four indole derivatives with various substituents at the 2-, 3- and 5-positions of the ring system are described, namely, ethyl 3-(5-chloro-2-phenyl-1H-indol-3-yl)-3-phenyl-propano-ate, C25H22ClNO2, (I), 2-bromo-3-(2-nitro-1-phenyl-eth-yl)-1H-indole, C16H13BrN2O2, (II), 5-meth-oxy-3-(2-nitro-1-phenyl-eth-yl)-2-phenyl-1H-indole, C23H20N2O3, (III), and 5-chloro-3-(2-nitr...

The recently reported growth-promoting ability of 3-methyl-eneoxindole was examined in order to test the hypothesis that indole-3-acetic acid acts as a growth promoter only after oxidative conversion to 3-methyleneoxindole. Methyleneoxindole was synthesized from indole-3-acetic acid and N-bromosuccinimide, and its identity was confirmed by ultraviolet absorption, infrared absorption, mass spect...

In the title compounds, C12H12N2O2, (I), and C17H14N2O2, (II), respectively, the indole rings are planar and the vinyl groups lie out of the indole planes, making dihedral angles of 33.48 (5) and 41.31 (8) degrees , respectively. In (II), the dihedral angle between the phenyl and indole ring planes is 32.06 (6) degrees . In both molecules, the double bond connecting the methylnitrovinyl group a...

The in vivo regulation of intermediate reactions in the pathway of tryptophan synthesis in Neurospora crassa was examined in a double mutant (tr-2, tr-3) which lacks the functions of the first and last enzymes in the pathway from chorismic acid to tryptophan. The double mutant can convert anthranilic acid to indole and indole-3-glycerol, and the production of these indolyl compounds by germinat...

Indole and its derivatives are typical nitrogen heterocyclic compounds and have been of immense concern since they are known for the risk of their toxic, recalcitrant, and carcinogenic properties for human and ecological environment. In this study, a Gram-negative bacterial strain of eliminating indole was isolated from a coking wastewater. The strain was confirmed as Acinetobacter pittii L1 ba...

In the presence of chloroperoxidase, indole was oxidized by H2O2 to give oxindole as the major product. Under most conditions oxindole was the only product formed, and under optimal conditions the conversion was quantitative. This reaction displayed maximal activity at pH 4.6, although appreciable activity was observed throughout the entire pH range investigated, namely pH 2.5-6.0. Enzyme satur...
