Sodium Dodecyl Sulfate Modified Carbon Nano Tube Paste Electrode for Sensitive Cyclic Voltammetry Determination of Isatin

Purpose: Isatin (IS) is a synthetically significant heterocyclic moiety with an influential pharmacodynamic indole nucleus and hence the electrocatalytic property of has been investigated. Methods: The electrochemical analysis was demonstrated by cyclic voltammetry (CV) in the potential window of 0.2 V to 1.4 V using sodium dodecyl sulfate (SDS) modified carbon nano tube paste electrode (SDSMCNTPE) over a pH range of 6 to 8.5 in 0.2 M phosphate buffer solution (PBS). Surface morphology was studied by using Field emission-scanning electron microscopy (FESEM). Results: The CV study discloses that under ideal condition oxidation of IS arises at a potential of 0.970 V accompanied with an exceptional stability, selectivity and sensitivity for the resultant SDSMCNTPE contrasting to bare carbon nano tube paste electrode (BCNTPE). Individual parameters like electrode surface area, effect of surfactant, detection limit, simultaneous detection of IS and resorcinol (RC) were studied at a scan rate of 0.1 V/s. Scan rate study uncovers the process is diffusion controlled. The oxidation peak current amplified linearly with the surge in concentration of IS under ideal condition. Detection limit (LOD) and limit of quantification (LOQ) in the solution of optimum pH (7.5) at a scan rate of 0.100V/s is 2.4×10(-7) M and 8.2 x 10(-7) M respectively. Conclusion: The proposed electrode portrays excellent repeatability, reproducibility and reliability to resistant electrode fouling.

Assembly of Indole Cores through a Palladium-Catalyzed Metathesis of Ar-X sigma-Bonds

We describe the development of a new method for construction of highly substituted indole scaffolds through the strategic utilizing of the metathesis of Ar-X sigma-bonds based on the dynamic nature of palladium-based oxidative addition/reductive elimination. A suitable and simple catalytic system has provided an appropriate platform for a productive ligand exchange and consecutive carbopalladation/C-H activation/amination of phosphine ligands with alkynes and aromatic/aliphatic amines for construction of structurally diverse indoles.

Synthesis, characterization and photophysical properties of meso-indole-boron-dipyrromethene derivatives and their cell imaging and viscosity sensing

Based on the molecular design and structural modification of boron-dipyrromethene (BODIPY), two new BODIPY derivatives with meso-substituted functional indole moieties were successfully prepared. These new compounds were characterized by NMR, HAMS and FTIR, exhibiting the different UV-vis and PL spectral phenomena because of their varied molecular structures in various solvents and different degrees of negative solvatochromism. Theoretical calculations and CV results show that the substituted NO2 group at 5-position of indole is favorable for increasing the oxidation potential of the molecules, while the NH2 group is the opposite. These two BODIPY derivatives have different sensitivities to pH changes, and can be appropriately applied as cell imaging materials due to their good physical chemical characteristics and excellent biocompatibility. In particular, the fluorescence characteristics of BODIPY derivative with the substituted NH2 group at 5-position of indole show a good solvent viscosity dependence, highlighting its potential application for testing the intracellular viscosity changes of the living cell in disease diagnosis.

Crystal structure of the acyl acid amido synthetase GH3-8 from Oryza sativa

The Gretchen Hagen 3 (GH3) family of acyl acid amido synthetases regulate the levels and activities of plant hormones containing carboxyl groups, thereby modulating diverse physiological responses. While structure-function relationships have been elucidated for dicotyledonous GH3s, the catalytic mechanism of monocotyledonous GH3 remains elusive. Rice (Oryza sativa) is a representative monocot, and its yield is controlled by the natural growth hormone IAA (indole-3-acetic acid). OsGH3-8 is a model GH3 enzyme that conjugates excess IAA to amino acids in an ATP-dependent manner, ensuring auxin homeostasis and regulating disease resistance, growth and development. Here, we report the crystal structure of OsGH3-8 protein in complex with AMP to uncover the molecular and structural basis for the activity of monocotyledonous GH3-8. Structural and sequence comparisons with other GH3 proteins reveal that the AMP/ATP binding sites are highly conserved. Molecular docking studies with IAA, the GH3-inhibitor Adenosine-5′-[2-(1H-indol-3-yl)ethyllphosphate (AIEP), and Aspartate provide important information for substrate binding and selectivity of OsGH3-8. Moreover, the observation that AIEP nearly occupies the entire binding site for AMP, IAA and amino acid, offers a ready explanation for the inhibitory effect of AIEP. Taken together, the present study provides vital insights into the molecular mechanisms of monocot GH3 function, and will help to shape the future designs of effective inhibitors.

Indole alkaloids from Gelsemium elegans

Five previously undescribed monoterpenoid indole alkaloids were isolated from the roots of Gelsemium elegans. Their structures with absolute configurations were elucidated by HRESIMS, X-ray diffraction, ECD spectra, and molecular modeling. 19,20-Epoxyhumantenine is a humantenine-type alkaloid with an epoxypropyl group at the C-20 position, (4R)-19-oxo-gelsevirine N-4-oxide is a gelsemine-related alkaloid, and gelsedethenine is a gelsedine-type alkaloid with a butenyl group at the C-20 position. Moreover, 10,11-dimethoxy-N-1-demethoxy-gelsemamide is an open-loop indole alkaloid and 11-demethoxy-gelsemazonamide is an aromatic azo-linked dimeric indole alkaloid. Among the five alkaloids, (4R)-19-oxo-gelsevirine N-4-oxide and 10,11-dimethoxy-N-1-demethoxy-gelsemamide exhibited significant inhibitory effects on nitric oxide production in lipopolysaccharide-induced RAW 264.7 macrophage cells, with IC50 values of 6.18 +/- 1.07 and 12.2 +/- 1.02 mu M, respectively.
