Structural, spectroscopic (FT-IR, FT-Raman, NMR) and computational analysis (DOS, NBO, Fukui) of 3,5-dimethylisoxazole and 4-(chloromethyl)-3,5-dimethylisoxazole: A DFT study

The theoretical and computational analysis of two isoxazole derivatives 3,5-dimethylisoxazole and 4-chloromethyl-3,5-dimethylisoxazole were carried out along with some of the experimental evidences. The density functional theory calculations of these compounds were done with DFT/B3LYP/6-31+G(d,p) basis set using Gaussian 09 software. From the DFT calculations, the optimization geometry, vibrational analysis, electronic properties, local reactivity descriptors, natural bond orbitals, and other structural properties of the title compounds were elucidated. The chemical shifts of every C and H atom of the title compounds were calculated using Gauge Independent Atomic orbitals (GIAO) method for both proton and carbon NMR spectra. The molecular electrostatic potential of DMI has been found out and the difference in MEP on addition of chloromethyl group is also discussed. The hyperpolarizability calculations of the investigated molecules shows that the nonlinear optical activity of CDMI is greater when compared to DMI.

Stress-dependent miR-980 regulation of Rbfox1/A2bp1 promotes ribonucleoprotein granule formation and cell survival

Upon stress, profound post-transcriptional adjustments of gene expression occur in spatially restricted, subcellular, membraneless compartments, or ribonucleoprotein (RNP) granules, which are formed by liquid phase separation of RNA-binding proteins with low complexity sequence domains (LCDs). Here, we show that Rbfox1 is an LCD-containing protein that aggregates into liquid droplets and amyloid-like fibers and promiscuously joins different nuclear and cytoplasmic RNP granules. Using Drosophila oogenesis as an in vivo system for stress response, we demonstrate a mechanism by which Rbfox1 promotes cell survival. The stress-dependent miRNA miR-980 acts to buffer Rbfox1 levels, since it targets only those Rbfox1 transcripts that contain extended 3?UTRs. Reduced miR-980 expression during stress leads to increased Rbfox1 levels, widespread formation of various RNP granules, and increased cell viability. We show that human RBFOX proteins also contain multiple LCDs and form membraneless compartments, suggesting that the RNP granule-linked control of cellular adaptive responses may contribute to a wide range of RBFOX-associated pathologies in humans.

Cocrystals of zonisamide: Physicochemical characterization and sustained release solid forms

We report four cocrystals of the antiepileptic drug, zonisamide (ZNS), which encounters half-life fluctuation when administered adjunctly with other antiepileptic drugs. Single crystals for two of the novel cocrystals of ZNS were successfully prepared from solvent evaporation experiments and their crystal structures were determined. Pharmaceutically acceptable cocrystals were analyzed for their dissolution rate, solubility and stability to draw conclusions on the impact of cocrystallization on the physicochemical properties of ZNS. It was found that the cocrystals showed lower solubility and dissolution rates and offer potential benefits in the development of sustained release formulations of ZNS which could address issues regarding its half-life fluctuation. Recent attempts to explore newer therapeutic applications have suggested ZNS as a potential drug for weight loss management. In this regard, the cocrystal of ZNS with caffeine, which has also been used in weight loss management, promises potential applications in the development of a novel fixed-dose combination drug which could offer synergistic therapeutic benefits in the treatment of obesity.

Novel small molecule targeting the hemagglutinin stalk of influenza viruses

Combating influenza is one of the perennial global public health issues to be managed. Antiviral drugs are useful for the treatment of influenza in the absence of an appropriate vaccine. However, the appearance of resistant strains necessitates a constant search for new drugs. In this study, we investigated novel anti-influenza drug candidates using in vitro and in vivo assays. We identified anti-influenza hit compounds using a high-throughput screening method with a green fluorescent protein-tagged recombinant influenza virus. Through subsequent analyses of their cytotoxicity and pharmacokinetic properties, one candidate (IY7640) was selected for further evaluation. In a replication kinetics analysis, IY7640 showed greater inhibitory effects during the early phase of viral infection than the viral neuraminidase inhibitor oseltamivir. In addition, we observed that hemagglutinin (HA)-mediated membrane fusion was inhibited by IY7640 treatment, indicating that the HA stalk region, which is highly conserved across various (sub)types of influenza viruses, May be the molecular target of IY7640. In an escape mutant analysis in cells, amino acid mutations were identified at the HA stalk region of the 2009 pandemic H1N1 (pH1N1) virus. Even though the in vivo efficacy of IY7640 did not reach complete protection in a lethal challenge study in mice, these results suggest that IY7640 has potential to be developed as a new type of anti-influenza drug. IMPORTANCE Anti-influenza drugs with broad-spectrum efficacy against antigenically diverse influenza viruses can be highly useful when no vaccines are available. To develop new anti-influenza drugs, we screened a number of small molecules and identified a strong candidate, IY7640. When added at the time of or after influenza virus infection, IY7640 was observed to successfully inhibit or reduce viral replication in cells. We subsequently discovered that IY7640 targets the stalk region of the influenza HA protein, which exhibits a relatively high degree of amino acid sequence conservation across various (sub)types of influenza viruses. Furthermore, IY7640 was observed to block HA-mediated membrane fusion of H1N1, H3N2, and influenza B viruses in cells. Although it appears less effective against strains other than H1N1 subtype viruses in a challenge study in mice, we suggest that the small molecule IY7640 has potential to be optimized as a new anti-influenza drug.

Harnessing the TEMPO-Catalyzed Aerobic Oxidation for Machetti-De Sarlo Reaction toward Sustainable Synthesis of Isoxazole Libraries

A practical synthesis of isoxazole/isoxazoline derivatives via Machetti-De Sarlo reaction under sustainable conditions has been accomplished. This protocol involves the use of readily available 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) to catalyze the cyclocondensation of primary nitroalkanes with alkynes/alkenes to afford a library of isoxazole/isoxazoline products. From an eco-benign perspective, notable advantages of this method are as follows: (i) water as the solvent, (ii) air as the oxidant, (iii) transition metal-free, (iv) no base required, (v) no toxic byproduct, (vi) no need of solvent extraction, (vii) diverse substrate scope, (viii) high chemical yields, (ix) excellent chemo- and regioselectivity, (x) short reaction time, (xi) gram-scale synthesis, (xii) extension to heterogeneous version, and (xiii) catalyst recyclability. For these reasons, the developed method is appropriate for safe laboratory use and can be expected to inspire the progress of TEMPO-based organocatalysis for the preparation of isoxazole/isoxazoline moieties in an environmentally benign fashion.

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 7063-99-2 is helpful to your research. Synthetic Route of 7063-99-2
