Metal-Free, Oxidant-Free, and Controllable Graphene Oxide Catalyzed Direct Iodination of Arenes and Ketones

A direct, metal-free, and oxidant-free method for the graphene oxide (GO)-catalyzed iodination of arenes and ketones with iodine in a neutral medium was explored. This iodination protocol was performed by using a simple technique to avoid the use of external metal catalysts and oxidants and harsh acidic/basic reaction conditions. In addition, by this method the degree of iodination could be controlled, and the reaction was scalable and compatible with air. This strategy opens a new field for GO-catalyzed chemistry and provides an avenue for the convenient direct iodination of arenes and ketones.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4923-87-9 is helpful to your research. 4923-87-9

Methoxy-substituted 3-formyl-2-phenylindoles inhibit tubulin polymerization

The aim of this study was the identification of the essential structural elements in the 12-formyl-5,6-dihydroindolo[2,1-a]isoquinoline system required for the inhibition of tubulin polymerization which is understood to be the predominant mode of action of this class of cytostatics. Since 2- phenylindole forms the main fragment of this tetracycle, it was used as the basic structure and modified with respect to the number and positions of the oxygen functions in the aromatic rings. Further modifications related to the nitrogen, which was both replaced by oxygen and sulfur and alkylated. All derivatives were tested for cytostatic activity in human breast cancer cells (MDA-MB 231, MCF-7) and inhibition of tubulin polymerization. The spectrum of activity ranged from inactive to IC50 values of 35 nM (cell growth inhibition) and 1.5 muM (tubulin polymerization), respectively, for the most active derivative 3e (3-formyl-6-methoxy-2-(4-methoxyphenyl)indole). Although the correlation between antiproliferative activity and inhibition of tubulin polymerization was not very pronounced, all of the potent cytostatic agents in this study disrupted microtubule assembly completely at the standard concentration of 40 muM. By fluorescence microscopy it was demonstrated that the derivative 3e degrades the cytoskeleton in a similar fashion as colchicine does leading to the condensation of the microtubules around the nucleus after treatment. The comparison between hydroxy and methoxy derivatives revealed a striking difference between the 2-phenylindole derivatives and the indoloisoquinolines. In the 2-phenylindole series, the methoxy compounds were much more effective than the free phenols, whereas in the tetracyclic system the effect of the hydroxy derivatives exceeded that of the methylated compounds by 1 order of magnitude. Preliminary studies on the binding mode showed that both the 2-phenylindole derivatives and the indoloisoquinolines bind to the colchicine site on tubulin.

Synthesis, binding assays, cytotoxic activity and docking studies of benzimidazole and benzothiophene derivatives with selective affinity for the CB2 cannabinoid receptor

Herein we report the design, synthesis, bioinformatic and biological studies of benzimidazole and benzothiophene derivatives as new cannabinoid receptor ligands. To test the hypothesis that the lack of a hydrogen bond interaction between benzimidazole and benzothiophene derivatives with Lys192 reduces their affinity for CB1 receptors (as we previously reported) and leads to CB2 selectivity, most of the tested compounds do not exhibit hydrogen bond acceptors. All compounds displayed mostly CB2 selectivity, although this was more pronounced in the benzimidazoles derivatives. Furthermore, docking assays revealed a ?-cation interaction with Lys109 which could play a key role for the CB2 selectivity index. The series displayed low toxicity on five different cell lines. Derivative 8f presented the best binding profile (Ki?=?0.08?muM), high selectivity index (KiCB1/KiCB2) and a low citoxicity. Interestingly, in cell viability experiments, using HL-60?cells (expressing exclusively CB2 receptors), all synthesised compounds were shown to be cytotoxic, suggesting that a CB2 agonist response may be involved.

Advances toward new antidepressants beyond SSRIs: 1-aryloxy-3-piperidinylpropan-2-ols with dual 5-HT1A receptor antagonism/SSRI activities. Part 2

Potent 5-HT1A/SSRIs at low nanomolar and subnanomolar concentrations were identified in a series of 1-(1H-indol-4-yloxy)-3-(4-benzo[b]thiophen-2-ylpiperidinyl)propan-2-ols. Incorporation of an alpha-Me group in the piperidine ring with its specific stereochemistry enhanced binding affinity at the 5-HT reuptake site and in vitro 5-HT1A antagonist functional activity.

A perfluorocyclopentene based diarylethene bearing two terpyridine moieties – Synthesis, photochemical properties and influence of transition metal ions

The synthesis of a perfluorocyclopentene based diarylethene bearing two terpyridine units is reported. Furthermore studies of the free ligand’s photochromism and investigations regarding the influence of various transition metal ions on the photochromic reaction are presented. The photochromism of the central diarylethene unit is strongly dependent on the transition metal present, vice versa the photochromic reaction seems to influence the MLCT transition of a binuclear Ru(II) complex.
