S center dot center dot center dot N chalcogen bonded complexes of carbon disulfide with diazines. Theoretical study

Carbon disulfide complexes with diazine (pyridazine, pyrimidine or pyrazine) have been studied by density functional BLYP-D3 and ab initio CCSD(T) methods. All possible conformers of these complexes have been found. In the chalcogen bonded complexes, the CCSD(T)/cc-pvtz calculated interaction energies (Delta E) range between -0.89 and -2.19 kcal mol(-1). These complexes are more stable than those stabilized by hydrogen bond. The linear correlation between the DE and the most negative values of the electrostatic potential surfaces (V-s,V-min) on the nitrogen atom of the diazines has been found. According to the symmetry- adapted perturbation theory (SAPT) analysis, in the chalcogen bonded complexes among all of the attraction forces the electrostatic component is the most important one, while in the hydrogen bonded and stacking complexes the dispersion contribution is the leading term. Moreover, the Natural Bond Orbitals (NBO), AIM and Noncovalent Interaction Index (NCI) analyses have been performed. (C) 2017 Elsevier B. V. All rights reserved.

Discovery of Novel Pyridazine-Based Cyclooxygenase-2 Inhibitors with a Promising Gastric Safety Profile

Cyclooxygenase-2 (COX-2) is implicated in the development of chronic inflammatory diseases. Recently, pyridazine derivatives have emerged as a novel prototype to develop COX-2 inhibitors. Accordingly, some pyridazine-based COX-2 inhibitors are reported herein. The reaction of aldehyde 3 and different hydrazines yielded the corresponding hydrazones. The hydrazones were further derivatized to the title compounds, which were assessed for COX-1 and COX-2 inhibitory action, gastric ulcerogenic effects, and lipid peroxidation properties. Molecular docking studies and determination of the physicochemical parameters were also carried out. The allocated structures of the reported compounds were coherent with their spectroscopic data. The compounds 9a (IC50 = 15.50 nM, 114.77%), 9b (IC50 = 17.50 nM, 101.65%), 12 (IC50 = 17.10 nM, 104.03%), 16b (IC50 = 16.90 nM, 105.26%), and 17 (IC50 = 17.70 nM, 100.5%) displayed better COX-2 inhibition than celecoxib (IC50 = 17.79 nM, 100%). These outcomes were harmonious with the molecular docking studies of 9a, 9b, 12, 16b, and 17. These compounds also displayed comparable onset and the duration of action concerning celecoxib and indomethacin in the in vivo studies. No ulcerogenic effects were observed for 9a and 12, whereas 9b, 16b, and 17 showed an insignificant ulcerogenic effect compared to celecoxib. The compounds 9a, 9b, 12, 16b, and 17 displayed a better lipid peroxidation profile than celecoxib and indomethacin. The compounds 9a (%ABS = 84.09), 9b (%ABS = 84.09), 12 (%ABS = 66.87), 16b (%ABS = 75.02), and 17 (%ABS = 81.42) also displayed appreciable calculated absorption compared to celecoxib (%ABS = 82.09). The compounds 9a, 9b, 11, 16b, and 17 have been recognized and postulated as non-ulcerogenic COX-2 inhibitors with promising physicochemical parameters and gastric safety profile. These compounds may be useful candidates to combat diseases caused by higher levels of COX-2.

Imidazo[1,2-b]pyridazine as Building Blocks for Host Materials for High-Performance Red-Phosphorescent Organic Light-Emitting Devices

A novel electron-transporting unit, imidazo [1,2-b]pyridazine (IP), was first reported for developing host materials. The IP moiety possesses excellent electron-transporting ability and great thermal stability. Using carbazole as p-type units and IP as n-type units, several bipolar host materials, namely, IP6Cz, IP68Cz, IP36Cz, and IP368Cz, were developed through altering the substitution site of the IP core. Among these four materials, 6-site-substituted IP6Cz and 6,8-site-substituted IP68Cz exhibit the best electroluminescence (EL) performance. IP6Cz- and IP68Cz-based red phosphorescent organic light-emitting diodes using Ir(pq)(2)acac as the emitter exhibit extremely high EL efficiency with the maximum external quantum efficiency (eta(ext,max)) of 26.9 and 25.2% and an insignificant efficiency roll-off. Moreover, IP6Cz- and IP68Cz-based deep-red devices doped by Ir(piq)(2)acac also show satisfactory EL performance with a eta(ext,max) of 20.5 and 19.9%, respectively. The influence of different substitution sites of the IP core on the photophysical and electrochemical properties was systematically investigated. This study demonstrates that IP could be a first-rate electron-transporting unit for bipolar materials for red-emitting devices.

Electron impact ionisation cross-sections for complex molecules

The main goal of this work is to compute the total ionisation cross-section for electron scattering from various complex molecules. The targets chosen are pyridazine, alanine, glycine, benzoic acid, phenylacetylene, ethylbenzene and n-propylbenzene. There is no previous literature available for these molecules except for pyridazine, alanine and glycine, and hence we present the first report of their ionisation cross-section. We apply the complex scattering potential-ionisation contribution (CSP-ic) method to compute the cross-sections from the respective ionisation threshold to 5000 eV. The result for the pyridazine molecule shows an excellent agreement with the available experimental data and binary encounter-Bethe (BEB) cross-sections. In the absence of any experimental comparison for other molecules, we have also calculated their BEB ionisation cross-sections. These two methods are well known for giving reasonable estimates of the ionisation cross-sections. The CSP-ic method is based on the molecular structure and properties, while the BEB method deals with molecular orbitals. Thus, comparing the two results will check the accuracy of these theoretical models and further increase the credibility of the reported cross-section. In general, fairly good agreement is observed between the two results. However, any inconsistencies observed are backed by valid reasons.

Discovery of Small Molecule Splicing Modulators of Survival Motor Neuron-2 (SMN2) for the Treatment of Spinal Muscular Atrophy (SMA)

Spinal muscular atrophy (SMA), a rare neuromuscular disorder, is the leading genetic cause of death in infants and toddlers. SMA is caused by the deletion or a loss of function mutation of the survival motor neuron 1 (SMN1) gene. In humans, a second closely related gene SMN2 exists; however it codes for a less stable SMN protein. In recent years, significant progress has been made toward disease modifying treatments for SMA by modulating SMN2 pre-mRNA splicing. Herein, we describe the discovery of LMI070/branaplam, a small molecule that stabilizes the interaction between the spliceosome and SMN2 pre-mRNA. Branaplam (1) originated from a high-throughput phenotypic screening hit, pyridazine 2, and evolved via multiparameter lead optimization. In a severe mouse SMA model, branaplam treatment increased full-length SMN RNA and protein levels, and extended survival. Currently, branaplam is in clinical studies for SMA.

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 88-17-5 is helpful to your research. Name: 2-(Trifluoromethyl)aniline.
