The front cover picture, designed by Tsuchimoto, illustrates the world of formation o-bis(3-indolyl)arenes that we had not anticipated. Before starting this research project, our purpose was to develop a unique-forming process 3-arylindoles reacting indoles with 7-oxabicyclo[2.2.1]hept-5-en-2-one in presence (Lewis) acid catalyst and H−Si. Contrary expectations, treatment two substrates CF3SO3H...

The glucosinolate(GS)-myrosinase system of Brassicaceae, including the model plant Arabidopsis thaliana (L.), comprises a defence which is effective especially against generalist herbivores. Based on their side chain structure GS are grouped into aliphatic, aromatic, and indolyl GS. Indolyl GS are widely distributed among A. thaliana ecotypes and the Brassicaceae family, but the presence of ali...

The reaction of indole derivatives with cyanoacetic acid followed by treatment with DMFDMA gave the intermediate indolyl enaminonitriles (3). Further reaction with aminoguanidine yielded 5 ́-cyanomeridianin analogues (4). The same intermediate reacted with pmethoxyphenylhydrazine to give the pyrazolyl derivative (8). Treatment of (2E)-3-dimethylamino-2-(1H-indol-3-yl)-propenoate (3a) with hydrox...

Tst-1/SCIP/Oct-6, a POU domain transcription factor, is transiently expressed by developing Schwann cells and is required for their normal development into a myelinating phenotype. In tst-1/scip/oct-6-null sciatic nerves, Schwann cells are transiently arrested at the "promyelinating" stage, when they have a one-to-one relationship with an axon but before they have elaborated a myelin sheath. To...

Nerve growth factor-induced B (NGFI-B) genes are orphan nuclear receptors, and NGFI-B alpha (Nur77, TR3) is overexpressed in bladder tumors and bladder cancer cells compared with nontumorous bladder tissue. 1,1-Bis(3'-indolyl)-1-(p-methoxyphenyl)-methane (DIM-C-pPhOCH(3)) and 1,1-bis(3'-indolyl)-1-(p-phenyl)methane have previously been identified as activators of Nur77, and both compounds inhib...

BACKGROUND Septic shock is a leading cause of mortality in intensive care units. No new interventions in the last 20 years have made a substantial impact on the outcome of patients with septic shock. Identification of inhibitable pathways that mediate death in shock is an important goal. MATERIALS AND METHODS Two novel caspase inhibitors, (2-indolyl)-carbonyl-Ala-Asp-fluoromethylketone (IDN 1...

Two new long chain tryptophan compounds viz [3-(indolyl-30)-2-(N-octadecamido)]-methylpropionate (4) and sodium-[3-(indolyl-30)-2(N-octadecamido)]-propionate (5) have been prepared and their ̄uorescence properties ( max, f, f, rss, quenching) have been investigated in homogeneous media and in phosphatidyl choline vesicles. Both 4 and 5 in a membrane mimicking system of phosphatidylcholine vesic...

The Rh(II)- and Cu(II)-catalyzed reactions of N-bis(trimethylsilyl)methyl, N-(2-indolyl)methyl α-diazoamides are investigated to delineate how conformational, steric and electronic factors influence the site- and chemoselectivity of the metallocarbenoid reaction. The N-bis(trimethylsilyl)methyl (N-BTMSM) group is found to be essential in promoting the metallocarbenoid reaction at the N-(2-indol...

N-(α-ketoacyl)anthranilic acids reacted with phenylhydrazinium chloride in boiling acetic acid to afford 2-(indol-2-carboxamido)benzoic acids in good to excellent yields and 2-indolyl-3,1-benzoxazin-4-ones as by-products. The formation of the latter products could easily be suppressed by a hydrolytic workup. Alternatively, by increasing the reaction temperature and/or time, 2-indolyl-3,1-benzox...
