A naphthalimide-based fluorescent probe for the highly sensitive and selective detection of nerve agent mimic DCP in solution and vapor phase

Although human beings enjoy a relatively peaceful atmosphere, chemical terrorist attacks are still a public safety emergency, and the ability to rapidly and precisely detect chemical warfare agents (CWAs) presents a major challenge. In this study, we have developed a simple fluorescent probe based on naphthalimide that displays high selectivity and sensitivity for the nerve agent mimic diethyl chlorophosphate (DCP) in DMF solution. This probe, which is weakly fluorescent because of the PET character of the piperazine moiety, displays significant green emission in the presence of DCP. Based on the fluorescence calibration curve, the detection limit of this DCP probe was measured to be as low as 5.5 nM. Futhermore, the probe solution or filter paper can be used to selectively and sensitively detect DCP vapor, which shows the potential of its practical application.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 111974-74-4, you can contact me at any time and look forward to more communication. Formula: C17H19Cl2N3S.

Irregularly Bridged Epipolythiodioxopiperazines and Related Analogues: Sources, Structures, and Biological Activities

Epipolythiodioxopiperazines (ETPs) are a class of biologically active fungal secondary metabolites characterized by a bridged polysulfide piperazine ring. Regularly, the sulfide functionality is attached in the alpha-positions of the dioxopiperazine scaffold. However, ETPs possessing irregular sulfur bridges have rarely been explored. This review summarizes that 83 compounds of this subtype have been isolated and characterized since the discovery of gliovirin in 1982. Herein, particular emphasis is given to the isolation, chemistry, and biological activity of this subtype. For a better understanding, a relevant summary focusing on the source microorganisms and their taxonomy is provided and will help elucidate the fascinating chemistry and biology of these unusual ETPs.

Reduction of 2-hydroxy-3-arylmorpholines to 3-aryl morpholines

2-Hydroxy-3-aryl morpholines are readily prepared from arylboronic acids, aqueous glyoxal, and 1,2-aminoethanols by a variant of the Petasis borono-Mannich reaction. We now show that the 2-hydroxy-3-aryl morpholines may be deoxygenated to 3-aryl morpholines by treatment with methanesulfonic anhydride and triethylamine to afford intermediate 3,4-dihydro-2H-1,4-oxazines, followed by reaction with a triacetoxyborohydride salt and acetic acid to afford 3-aryl morpholines. This reaction sequence constitutes a three step, two pot preparation of 3-aryl morpholines from readily available starting materials (1,2-aminoethanols, arylboronic acids, and glyoxal) with excellent functional group tolerance and adaptability to scale.

Intending biological activities and SAR we propose replacements of fluorine, methyl and methoxy of synthetic compounds for noteworthy antimicrobial, antioxidant, anticancer and anti-tuberculosis activities. Among these compounds 3a, 4a and 5e were progressively strong against E. coli and K. pneumonia. Whereas, compounds 4a, 5a and 6a with addition of various functional groups (OCH3, CH3) were excellent against S. aureus and B. subtilis. Compound 5c exhibited strong RSA and dynamic ferrous ion (Fe2+) metal chelating impact with IC50 of 7.88 +/- 0.93 and 4.06 +/- 0.31 mu g/mL, respectively. Compound 5e was considerably cytotoxic against all cancer cells displaying activity better than the standard drug. Compounds 6b and 6e inhibited M. tuberculosis (MIC 1.0 mg/L) considerably.

An entry to non-racemic beta-tertiary-beta-amino alcohols, building blocks for the synthesis of aziridine, piperazine, and morpholine scaffolds

A method for the preparation of enantiopure beta-tert-amino alcohols bearing a tetrasubstitutedC-stereocenter, as well as their conversion into selected medicinally privileged heterocyclic systems (morpholines, aziridines, piperazines) is reported. These compounds were obtained through enantiospecific sigmatropic rearrangement of allyl carbamates as a key step. The latter were prepared from the corresponding beta,beta ‘-dialkyl-substituted non-racemic allyl alcohols. In addition, an asymmetric synthesis of such highly substituted allylic alcoholsviaeither enantioselective 1,2-reduction of enones, enzymatic kinetic resolution, or a functionalization of chiral propargyl alcohols, with discussion of scope and limitations of each method is reported.

Predicting the Shear Viscosity of Carbonated Aqueous Amine Solutions and Their Blends by Using an Artificial Neural Network Model

In the present work, a neural network (NN) model based on quantitative structure-viscosity relationship was implemented for predicting the shear viscosity of CO2-loaded and CO2-free aqueous amine solutions and their blends. A total of 1682 amine + CO, + water viscosity data sets for primary, secondary, and tertiary amines and 220 data points for further accuracy examinations were used. Molecular mechanic methods with CHARMM + CFF force fields were utilized in order to optimize, simulate, and extract the required molecular structure properties. Then, weighted nearest neighbor feature selection algorithm was used for selecting the most influencing descriptors, while cascade-forward NN (CFNN) model was applied for prediction purposes. For generality examinations, CO2-loaded aqueous systems of 3DMA1P(1) + EAE(2), MEA(1) + PZ(2), DMA2P(1) + MEA(2), DEAE(1) + PZ(2), and CO2 + pure water were used to find the solution viscosities, and comparisons were made against experimentations, which showed the quite robustness of the proposed model for the systemsm which were completely unaware of the trained model. Comparison between the values of average relative deviation of the NN model and the most important semiempirical viscosity models showed that CFNN model outperforms the other alternatives.

0D to 3D Pr-III metal-organic networks crystal engineered for optimal iodine adsorption

Four new praseodymium(III) metal-organic compounds varying in dimensionality from 0D to 3D have been designed and synthesized based on N-heterocyclic polycarboxylic acids, including pyridine-2,6-dicarboxylic acid (H(2)pydc) and pyrazine-2,3-dicarboxylic acid (H(2)pzdc). Altering the concentration of piperazine (pip, ancillary ligand) enables control over the dimensionality of the compound by switching between the 0D [H(2)pip][Hpip][Pr(pydc)(3)]center dot 4H(2)O (I) and the 1D {[Pr(pydc)( Hpydc)(H2O)(2)]center dot 4H(2)O}(n) (II) coordination polymer (CP). Upon replacing H(2)pydc with H2pzdc, CP II is converted to the 2D CP [Pr(pzdc)(Hpzdc)(H2O)(3)](n) (III) and using the metalloligand [Zn(Hpzdc)(2)(H2O)(2)](2-) the 3D heterometallic CP {[Pr2Zn(pzdc)(4)(H2O)(6)]center dot 2H(2)O}(n) (IV) is formed. Compound IV shows high stability in the absence of uncoordinated solvent molecules and is stable up to 400 degrees C, even in the presence of humidity. Therefore, IV was utilized for iodine adsorption in the vapour phase and in the presence of humidity. The results confirm the remarkable potential of IV for reversible adsorption of iodine vapour.

Alterations in Mediterranean mussel (Mytilus galloprovincialis) composition exposed to cyanotoxins as revealed by analytical pyrolysis

Cylindrospermopsin (CYN) and Microcystin-LR (MC-LR) are biotoxins produced by cyanobacteria species that, due to climate change and water eutrophication, proliferate together with an increase of the associated cyanotoxins. Both toxins are usually found in the aquatic environment and filter feeding organisms such as mussels are particularly exposed which may be the cause of metabolic alterations. In this work, pyrolysis gas chromatography mass spectrometry (Py-GC/MS) is used to evaluate compositional changes in mussel (M. galloprovincialis) after exposure for 14 days to cyanotoxins of Chrysosporum ovalisporum (CYN), Microcystis aeruginosa (MC-LR) and to a combination of both toxins. The pyrolysis of mussel flesh produced complex chromatograms, with up to 100 different compounds, but very similar between treatments. Major groups found were N compounds (pyridine, N-alkyl molecules) (18.2 % +/- 1.5) and peptide/protein derived compounds that include alkyl indols and diketo-piperazines (DKPs) (17.7 % +/- 2.4), series of medium chain length (C-14-C-22) saturated, mono and polyunsaturated fatty acids (45.1 % +/- 5.0), steroids (7.5 % +/- 0.6) and aromatics with undetermined origin (8.9 % +/- 1.1). A chemometric treatment of the chromatographic data allowed the discrimination between the different mussel populations exposed to cyanotoxins. The results are discussed in terms of the probable effects exerted by the biotoxins in mussel composition and the possible metabolic pathways affected.
