A new chromophore, 2-(4-nitrophenyl)-1H-indole (NPI), was synthesized as a potential photolabile protecting group. Caged benzoic acids featuring the NPI chromophore were model compounds. Benzoic acid released in moderate yields (~ 40–60%) upon photolysis of caged without any additional chemical reagents. Interestingly, an aldehyde, 1-(5-(1-formyl-1H-indol-2-yl)-2-nitrophenyl)ethyl benzoate, iso...

2-(3-(1H-Indol-3-yl)-5-(p-tolyl)-4,5-dihydro-1H-pyrazol-1-yl)-4-substituted-5-(substituted diazenyl)thiazoles and 2-(1H-indol-3-yl)-9-substituted-4,7-disubstituted pyrido[3,2-e][1,2,4]triazolo[4,3-a]pyrimidin-5(7H)-ones were synthesized via reaction of hydrazonoyl halides with each of 3-(1H-indol-2-yl)-5-(p-tolyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide and 7-(1H-indol-3-yl)-2- thioxo-5-substi...

Indole glucosinolates, derived from the amino acid Trp, are plant secondary metabolites that mediate numerous biological interactions between cruciferous plants and their natural enemies, such as herbivorous insects, pathogens, and other pests. While the genes and enzymes involved in the Arabidopsis thaliana core biosynthetic pathway, leading to indol-3-yl-methyl glucosinolate (I3M), have been ...

The synthesis of (2R,S)-1-(6-methoxy-4-(methoxymethyl)-1H-indol-5-yloxy)-3-(2-(2-methoxyphenoxy)ethylamino)propan-2-ol and (2R,S)-1-(4-methoxy-6-(methoxymethyl)-1H-indol-5-yloxy)-3-(2-(2-methoxyphenoxy)ethylamino)propan-2-ol is described. The compounds were tested for electrographic, antiarrhythmic, hypotensive, and spasmolytic activity, as well as for alpha(1)-, alpha(2)- and beta(1)-adrenocep...

5-phenyl-1,3,4-thiadiazol-2-amine (1), on reaction with substituted indolaldehyde in presence of glacial acetic acid give N-((2-substituted indol-3-yl)methylene)-5-phenyl-1,3,4-thiadiazol-2-amine (26). The compounds 2-6 when treated with acetyl chloride in presence of triethylamine undergo cycloaddition to produce 4-(2-substituted indol-3-yl)-1-(5-phenyl-1,3,4-thiadiazol-2-yl)azetidin-2-one (7-...

Successful alkylations of the nitrogen of ethyl indol-2-carboxylate were carried out using aq. KOH in acetone. The respective N-alkylated acids could be obtained without separating the N-alkylated esters by increasing the amount of KOH and water. The use of NaOMe in methanol led to transesterification instead of the alkylation, while the use of NaOEt led to low yields of the N-alkylated acids. ...

Much data in the literature suggest a role for protein kinase C (PKC) in regulating keratinocyte proliferation and differentiation. Nevertheless, the exact role of this family of isoenzymes is unclear, since PKC agonists (e.g., phorbol esters) are known to stimulate expression of both proliferative and differentiative markers in keratinocytes. Similarly, PKC inhibitors have been demonstrated bo...

The aim of the present study is to synthesize some novel ecofriendly fungicides and bactericides of indole-2,3-dione derivatives, having important pharmacodynamic significance. The ligands used in the present account are derived by the condensation of 1,3-dihydro-3-[2-(phenyl)-2-oxoethylidene]-2H-indol-2- one, 1,3-dihydro-3-[2-(4-nitrophenyl)-2-oxoethylidene]-2H-indol-2-one and 1,3-dihydro-3-[2...

The novel organic salt 7-((5-bromo-1H-indol-3-yl)(4-methoxyphenyl)methyl)1,3,5-triaza-7-phosphaadamantan-7-ium tetrafluoroborate was synthesized from a Lewis acid (LA) and Lewis-base (LB) reaction between 1,3,5-triaza-7-phosphaadmantane 5-bromo-3-(4-methoxybenzylidene)-3-H-indol-1-ium (LA). obtained base adduct, being the title compound, analyzed validated by 1H, 13C, 31P, 19F 1D-NMR-spectrosco...

In the paper by Vishnupriya, Suresh, Bharkavi et al. (2014), the chemical name in the title should be given as ‘4-(2bromophenyl)-2-(1H-indol-3-yl)-6-(thiophen-2-yl)pyridine-3carbonitrile’ and the correct scheme is shown below. In the paper by Vishnupriya, Suresh, Gunasekaran et al. (2014), the chemical name in the title should be given as ‘4-(4chlorophenyl)-2-(1H-indol-3-yl)-6-phenylpyridine-3-...
