Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 21598-06-1, molcular formula is C9H7NO3, introducing its new discovery. HPLC of Formula: C9H7NO3

The hitherto unknown 5,6-dihydroxy-3-mercaptoindole (4a) and its 2-carbomethoxy derivative (4b), as well as the analogous 5-hydroxy 3-mercaptoindoles, have been conveniently obtained as O,S-acetyl derivatives 3a-d by thiocyanation of the corresponding acetoxyindoles 1a-d with the NH4SCN/oxone system followed by SmI2 reduction and acetylation.

(Chemical Equation Presented) An original TiCl4/t-BuNH 2-mediated hydroamination/annulation domino reaction of delta-keto-acetylenes is described. The synthesis of pyrrolo[1,2-a]indole-2- carbaldehydes, starting from 2-carbonyl-1-propargyl-1H-indoles runs under mild reaction conditions, A conceivable mechanism is also discussed. TiCl4 has proved to be an effective multiactivity reagent: catalyst/Lewis acid/water scavenger. Some unpublished 2-carbonyl-1-propargyl-1H-indoles are prepared by means of Suzuki- and Negishi-lype reactions.

Rh2(S-DOSP)4-catalyzed decomposition of heteroaryldiazoacetates in the presence of styrene results in highly diastereoselective and enantioselective cyclopropanations. Heteroaryldiazoacetates containing both electron-rich and electron-deficient heterocycles, such as thiophene, furan, pyridine, indole, oxazole, isoxazole, and benzoxazole, are effective in this chemistry. These studies broaden the range of diazo compounds containing both electron-withdrawing and electron-donating groups, which undergo highly diastereoselective cyclopropanations.

For the purpose of obtaining orally potent VLA-4 inhibitors, we have carried out structural modification of the (N?-phenylureido)phenyl group in compound 1, where the group was found to be attributed to poor pharmacokinetic profile in our previous research. Through modification, we have identified several compounds with both potent in vitro activity and improved oral exposure. In particular, compound 7e with 7-fluoro-2-(1-methyl-1H-indol-3- yl)-1,3-benzoxazolyl group as a novel replacement of the (N?-phenylureido) phenyl group significantly inhibited eosinophil infiltration into bronchoalveolar lavage fluid at 15 mg/kg in an Ascaris-antigen-induced murine bronchial inflammatory model, and its efficacy was comparable to that of the anti-mouse alpha4 antibody (R1-2).

Objective: This study was aimed to investigate the in vitro antioxidant, antimicrobial, cytotoxicity, and enzyme inhibition activities of Tragopogon porrifolius and Polygonum cognatum which are naturally grown and consumed intensively by people in Sivas, Turkey. Methods: Plant materials were extracted with aqueous ethanol by maceration method. The components of the extracts were determined using the Gas Chromatography Mass Spectrometry. Antimicrobial, cytotoxic and enzyme inhibition activities of the extracts were investigated by micro dilution, XTT assay and 96-micro-well plate methods, respectively. The antioxidant activity evaluated using the DPPH radical scavenging, thiobarbituric acid and reducing power methods. The total phenol and total flavonoid content was also examined. Results: GC?MS analysis revealed the presence of 31 compounds inP. cognatum extract and 29 compounds in T. porrifolius extract. According to the results, T. porrifolius extract showed high level of antioxidant activity in comparison to P. Cognatum extract. T. porrifolius exhibited higher alpha-glucosidase inhibitory activity, and both extract showed strong alpha-amylase inhibition activity compared to reference drug acarbose. T. porrifolius and P. cognatum ethanolic extracts exhibited antimicrobial activity in the concentration range of 0.039?2.5 mg/ml. Both extracts also exhibited significant anticancer effect on MDA-MB-231 breast cancer cells. The IC50 values of T. porrifolius and P. cognatum extracts in MDA-MB-231 cells were determined as 0.0625 mg/mL and 0.053 mg/mL, respectively. Conclusion: Our findings demonstrated that T. porrifolius and P. cognatum ethanolic extracts have promising effect on antioxidant, antimicrobial and cytotoxic activity as well as enzyme inhibition activity, and hence further studies required to identify specific compounds responsible for these activities.

Negative allosteric modulators (NAMs) of GluN2B-containing NMDARs provide pharmacological tools for the treatment of chronic neurodegenerative diseases. Novel NAMs have been designed on the basis of computational studies focused on the ‘hit compound’ 3. This series of indoles has been tested in competition assay. Compounds 16 and 17 were the most active ligands (IC50 values of 83 nM and 71 nM, respectively) and they showed a potency close to that of reference compounds ifenprodil (1, IC50 = 47 nM) and 3 (IC50 = 25 nM). Furthermore, docking studies have been performed for active ligand 16 and the results were in a good agreement with biological data.

Air- and moisture-stable and recyclable palladium nanoparticles supported on modified single-walled carbon nanotubes (SWCNT-Met/Pd) behave as very efficient heterogeneous catalysts in the Ullmann coupling of imidazoles and indoles with aryl iodides to afford the corresponding C-N coupling reactions under aerobic conditions. These cross coupled products were produced in excellent yields at low palladium loading (?0.2 mol%) and the heterogeneous catalyst can be readily recovered by simple filtration and reused five times without a noticeable loss in its catalytic activity.
