Abstract:

ABSTRACT Since indole is present at up to 500 μM in the stationary phase and is an interspecies biofilm signal (J. Lee, A. Jayaraman, and T. K. Wood, BMC Microbiol. 7:42, 2007), we investigated hydroxyindoles as biofilm signals and found them also to be nontoxic interspecies biofilm signals for enterohemorrhagic Escherichia coli O157:H7 (EHEC), E. coli K-12, and Pseudomonas aeruginosa. The genetic basis of EHEC biofilm formation was also explored, and notably, virulence genes in biofilm cells were repressed compared to those in planktonic cells.

Abstract:

ABSTRACT Various pineal gland indole metabolites were separated by thin-layer chromatography after organ culture with tritiated serotonin. The amounts of methoxyindoles produced were remarkably constant and female rats in oestrus appeared to produce greater amounts than male rats. The results show a correlation between methylation and the concentration and affinity of the various hydroxyindoles for hydroxyindole-O-methyltransferase. J. Endocr. (1986) 111, 133–136

Abstract:

The basic synthetic methods for obtaining N-hydroxyindoles were studied. The first method is intramolecular reductive cyclization of ortho-substituted nitroaromatic compounds by various reducing agents. Nitrophenyl acetaldehydes (synthesis by Acheson), N,N-disubstituted amino-2-nitrostyrenes (synthesis by Somei), ortho-nitroketoetheres of different structure or 1-(o-nitroarene)-1-cyanoalkylnitroketones, ortho-nitrophenylacetonitriles were used as substrates for the synthesis of N-hydroxyindoles.

Abstract:

A recent study showed that N-acylserotonin derivatives have strong inhibitory activity against tyrosinase. To clarify the role of the 5-hydroxy group in the indole ring, 2-, 4-, 5-, 6-, and 7-hydroxyindole and 11 related compounds such as 5-hydroxyindan and 6-hydroxyquinoline were tested for their inhibition of catecholase activity of tyrosinase from human HMVII melanoma cells. 6-Hydroxyindole (5) and 7-hydroxyindole (6) were potent inhibitors, while 5-hydroxyindole (4) was a weaker inhibitor than the above-mentioned compounds (IC50 = 20, 79, 366, and 342 μM for 5, 6, 4, and kojic acid, respec

Abstract:

ABSTRACT Indole metabolites were separated by thin-layer chromatography following organ culture of rat pineal glands with tritiated tryptophan. Methoxyindole production was shown to differ substantially from results obtained when pineal glands were incubated with radiolabelled serotonin. The correlation between hydroxy- and corresponding methoxyindoles was, however, remarkably similar to previous results, and indicated that in the pineal gland, it is probable that production of methoxyindoles is dependent on the concentration of the various hydroxyindoles and their relative affinities for hydr

Abstract:

The aim of this study was to characterize the embryonic ontogeny of 5-hydroxyindoles and 5-methoxyindoles synthesis pathways in the goose pineal organ. The study was performed on embryos aged 14–28 days, which have been incubated under a 12L:12D cycle. The pineal organs were collected for measurements of indole content by HPLC every 6 h on embryonic day (ED) 14, ED 16, ED 18 and ED 22 or every 2 h on ED 24, ED 26 and ED 28. The level of tryptophan showed no significant changes during development and no day-night variations. The content of 5-hydroxytryptophan increased between ED 14 and ED 26.

Abstract:

Presented dissertation thesis is focused on the development of electrochemical methods for the determination of three important tumour biomarkers, namely homovanillic acid (HVA), vanillylmandelic acid (VMA), and 5-hydroxyindole-3-acetic acid (5-HIAA). First part of the study is focused on electrochemical behaviour of these analytes in batch arrangement using differential pulse voltammetry (DPV) at screen-printed carbon electrodes (SPCEs). It has been proved that presented method is sufficiently sensitive for monitoring above mentioned analytes. Moreover, it can be used for determination of HVA
