A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 167869-21-8, Name is PD98059, molecular formula is C16H13NO3.

Over the last decade, there has been substantial interest in the use of melatonin (MLT) and MLT-like compounds in the treatment of several diseases. MLT can scavenge different reactive oxygen species and can also stimulate the synthesis of antioxidant enzymes. Our ongoing study relies on changing the groups in the different modifiable sites of the indole ring to increase the antioxidant activity. In this study a new approach for substitution of indole ring as indole based MLT analogue was proposed. We report the synthesis and characterization of a series of new indole-7-aldehyde hy-drazide/hydrazone derivatives as indole-based MLT analogues. Anticancer potential of the compounds were evaluated both by their antioxidant and CYP1 inhibitory activities. In vitro antioxidant capacity of the compounds was investigated both in a cell-based (DCFH assay) and a cell-free (DPPH assay) assay. Potential inhibitory effects of the compounds on CYP1 catalytic activity were investigated via EROD assay. Cytotoxic activity of the compounds was further evaluated by the MTT assay in CHO-K1 cells. MLT analogues having an o halogenated aromatic moiety exhibited effective antioxidant properties without having any cytotoxic effect. In conclusion, MLT derivatives represent promising scaffolds for discovery of effective antioxidant agents.

1-[1-(4-Chlorobenzenesulfonyl)-1H-indole-3-yl]-3-[4-(pyridin-2-yl)piperazin-1-yl]propan-1-one

The title compound was prepared by an aza-Michael addition reaction between 1-[1-(4-chlorobenzenesulfonyl)-1H-indole-3-yllprop-2-en-1-one and 2-piridylpiperazine catalyzed by SiO2. The structural identity of the title compound was proven by elemental analysis and spectroscopic methods (IR, NMR). The compound was assayed in a binding assay at the 5-HT6 receptor, showing poor affinity.

Orientation-dependent effects of indeno [1,2-b] indole-spirofluorene donor on photovoltaic performance of D-pi-A and D-D-pi-A sensitizers

Dyes JY70-73 based on indeno[1,2-b]indole-spirofluorene (IISF) donor have been synthesized and applied in dye-sensitized solar cells, two of them feature donor-pi-acceptor (D-pi-A) configuration and the others adopt a D-D-pi-A structure. Orientation-dependent effects of IISF donor are clearly observed in the photovoltaic properties of D-pi-A type dyes JY70 and JY72, though close power conversion efficiency (PCE) achieves finally owing to the trade-off effect of open-circuit voltage (V-OC) and short-circuit current density (J(SC)). By contrast, regioisomeric dyes JY71 and JY73 with an auxiliary diphenylamine donor present a significantly different photovoltaic performance. Under the [Co(phen)(3)](2+/3+) electrolyte, device based on JY73 gives much higher V-OC and J(SC), hence a greater PCE (7.40%) which is over two times higher than its regioisomeric JY71 (3.31%). Reasons for that have been systematically investigated. Cocktail co-sensitizations of dyes JY73 and JY70/JY72 both promote the PCEs up to over 8%, and device based on JY72&JY73 achieves the highest PCE of 8.32%.

Cu-catalysed direct bis-thiolation of benzoheterocycles with arylsulfonyl hydrazides

A series of bis-arylsulfenylated indoles (10), benzofurans (3), and benzothiophenes (3) and of monosulfenylated indoles (5), 12 of which are novel, were prepared in good yields via a Cu-catalysed direct sulfenylation of benzoheterocycles with arylsulfonyl hydrazides. Sulfonothioates are probably the major thiolated intermediates in this transformation.
