Synthesis and investigations of the absorption spectra of hetarylazo disperse dyes derived from 2,4-quinolinediol

Synthesis of some novel hetarylazoquinoline dyes was achieved by diazotisation of nine heterocyclic amines using nitrosyl sulphuric acid, coupling with 2,4-quinolinediol. These dyes were characterized by UV-vis, FT-IR and 1H NMR spectroscopic techniques and elemental analysis. Visible absorption spectra of the dyes are discussed, both the effects of varying pH and solvent upon the absorption ability of azoquinolines. The colour of the dyes was discussed with respect to the nature of the heterocyclic ring and to the substituents therein. Temperature and concentration effects on the visible absorption maxima of the dyes are also reported.

Histone acetyltransferase inhibitors: An overview in synthesis, structure-activity relationship and molecular mechanism

Acetylation, a key component in post-translational modification regulated by HATs and HDACs, is relevant to many crucial cellular contexts in organisms. Based on crucial pharmacophore patterns and the structure of targeted proteins, HAT inhibitors are designed and modified for higher affinity and better bioactivity. However, there are still some challenges, such as cell permeability, selectivity, toxicity and synthetic availability, which limit the improvement of HAT inhibitors. So far, only few HAT inhibitors have been approved for commercialization, indicating the urgent need for more successful and effective structure-based drug design and synthetic strategies. Here, we summarized three classes of HAT inhibitors based on their sources and structural scaffolds, emphasizing on their synthetic methods and structure?activity relationships and molecular mechanisms, hoping to facilitate the development and further application of HAT inhibitors.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Recommanded Product: 288-16-4

Tert-Butyl 1,5-bis(4-(benzo[d]isothiazol-3-yl)piperazin-1-yl)-1,5- dioxopentan-2-ylcarbamate urea/thiourea derivatives as potent H +/K+-ATPase inhibitors

Amino acids are known to possess variable efficacy against ulceration. Considering the good antiulcer activity of amino acids, a series of urea/thiourea derivatives of glutamic acid conjugated benzisothiazole analogue 3a-u with various substituents on aryl ring were synthesized, spectroscopically characterized and evaluated for in vitro H+/K+-ATPase inhibition. Majority of the compounds possessed potency compared to that of omeprazole, a reference drug. In particular, methoxy derivatives 3p-u were the most active compounds possessing a significant 15-fold increase for para substituent thus, contributing positively to gastric H+/K +-ATPase inhibition.

Collection of ion-trap mass spectre of sulfonylurea pyrolysis products

The pyrograms of 14 sulfonylureas, i.e. herbicides characterized by high biological activity and low application dose are discussed and the mass spectra of over 30 relevant pyrolysis products as obtained with a heated filament pyrolyzer interfaced to a capillary gas chromatograph/ion-trap detector mass spectrometer are presented. Such a data compilation is useful for diagnostic purposes for both intact sulfonylureas and their metabolites after degradation in soil, because metabolites and pyrolysis products are often identical and most of their mass spectra are lacking in commercially available mass spectral libraries. The performance of the ion-trap detector based on the quality of the mass spectra is briefly discussed.

SPECTROSCOPIC PROPERTIES AND PROTONATION EQUILIBRIA IN 1,2-BENZISOTHIAZOLES

The protonation equilibria of 1,2-benzisothiazoles, involving substituents at position 3, or the ring nitrogen at position 2, have been investigated by potentiometric and/or spectrophotometric methods.The values of the protonation constants (log Kobs) have been compared with values calculated according to the linear relationships of Barlin and Perrin.For compounds with substituents at position 3, the protonation constants have been determined potentiometrically.The presence of the benzisothiazole moiety induces an increase of base strength, with respect to that expected from the calculated substituent effects according to Barlin and Perrin.The protonation constants of the heterocyclic nitrogen at position 2 have been determined spectroscopically in very acidic solutions.The comparison of the values observed with those calculated following Barlin and Perrin for substituted isoquinoline shows that the ring nitrogen is less basic than expected.
