RHF and DFT calculations were carried out to study the optimized molecular geometries and vibrational characteristics of the 4,5-ethylenedithio-1,3-dithiole-2-thione (EDT-DTT) and 4,5-ethylenedithio-1,3-dithiole-2-one (EDT-DTO) molecules and their radical cations and anions. It is found that the anionic radical of the EDT-DTO molecule is unstable. Both the neutral molecules and their radical cations have non-planar structures with C-2 symmetry while the radical anion of the EDT-DTT molecule has non-planar structure with C-1 symmetry. It is found that the most of the vibrational characteristics of the radicals are similar to their corresponding neutral molecules, however, for some of the modes significant changes are noticed. As a result of anionic radicalization of EDT-DTT, the IR intensity and Raman activity increase and Raman band becomes polarized for both the CH2 twisting modes. Drastic enhancements in the Raman activity and reduced IR intensity are noticed for the C=S/O stretching mode in going from neutral molecules to their radical ions consistent with charge separation along this bond. The C=S and C=C stretching wavenumber changes are consistent with corresponding bond length changes in going from neutral to their radical ions. (C) 2010 Elsevier B.V. All rights reserved.

New bioactive N-acylhydrazone derivatives synthesized from safrole previously have been found to promote intense vasodilation and antihypertensive activity. In this study, we describe the synthesis and the cardiovascular effects of the new N-acylhydrazone derivative (E)-N-methyl-N ‘-(thiophen-3-ylmethylene)benzo[d][1,3]dioxole-5-carbohydrazide (LASSBio-1289). Thoracic aorta and left papillary muscles from Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR) were prepared for isometric tension recording. LASSBio-1289 promoted relaxation of endothelium-intact and denuded aortic rings with respective pIC(50) (-log IC50) values of 5.07 +/- 0.09 and 4.26 +/- 0.09 (P<0.001) for WKY rats and 5.43 +/- 0.05 and 5.58 +/- 0.07 (P>0.05) for SHR. The vasodilator activity of LASSBio-1289 was increased in the KCl-contracted aorta. LASSBio-1289 attenuated the contracture elicited by Ca2+ in depolarized aorta from both WKY rats and SHR. In endothelium-intact aorta from WKY rats, LASSBio-1289-induced relaxation was unchanged after incubation with propranolol, ZM 241385, atropine, diphenhydramine, and HOE140, but was significantly reduced by L-NAME and ODQ. LASSBio-1289 decreased papillary muscles contractility only at concentrations above 200 mu m. Acute intravenous injection of LASSBio-1289 (3mg/kg) produced a significant hypotensive response in SHR but not in WKY rats, suggesting its antihypertensive profile. The antihypertensive effect was also observed in SHR during 14days of intraperitoneal and oral administration. In conclusion, our data demonstrated that LASSBio-1289 induces both endothelium-independent vasorelaxation involving the inhibition of Ca2+ influx through L-type Ca2+ channels in aorta from WKY rats and SHR, and endothelium-dependent relaxation mediated by the NO/cyclic GMP pathway in WKY rats.

Difluorinated alkenoate ethyl 3,3-difluoro-2-(N, N-diethylcarbamoyloxy)-2-propenoate reacts rapidly and in high yield with furan and a range of substituted furans in the presence of a tin(IV) catalyst. Non-fluorinated congener 2-(N, N-diethylcarbamoyloxy)-2-propenoate fails to react at all under the same conditions. These reactions have been explored using density functional theory (DFT) calculations. They reveal a highly polar transition state, which is stabilized by the Lewis acid catalyst SnCl4 and by polar solvents. In the presence of both catalyst and solvent, a two-step reaction is predicted, corresponding to the stepwise formation of the two new carbon-carbon bonds via transition states which have similar energies in all cases. Our experimental observations of the lack of reaction of the non-fluorinated dienophile, the stereochemical outcomes, and the rate acceleration accompanying furan methylation are all well predicted by our calculations. The calculated free energy barriers generally correlate well with measured reaction rates, supporting a reaction mechanism in which zwitterionic character is developed strongly. An in situ ring opening reaction of exo-cycloadduct ethyl exo-2-(N, N-diethylcarbamoyloxy)-3,3-difluoro-7-oxabicyclo[2.2.1] hept-5-enyl-2-endo-carboxylate, which results in the formation of cyclic carbonate ethyl 4,4-difluoro-5-hydroxy-2-oxo-5,7a-dihydro-4H-benzo[1,3] dioxole-3a-carboxylate by a Curtin-Hammett mechanism, has also been examined. Substantial steric opposition to Lewis acid binding prevents carbonate formation from 2-substituted furans.

Methacrolein is a major product of isoprene ozonolysis, and methacrolein oxide is an important ozonolysis intermediate. We use CBS-QB3 and RRKM/master equation calculations to characterize all methacrolein formation pathways and all the unimolecular reactions of methacrolein oxide. Our predicted methacrolein yield agrees with experiment if we assume that all of the dioxirane formed from methacrolein oxide decomposes to methacrolein. The vinyl group of methacrolein oxide allows the species to cyclize to a dioxole with a reaction barrier lower than the barriers to either hydroperoxide or dioxirane formation. Two dioxole derivatives, 1,2-epoxy-2-methyl-3propanal and 2-methyl-3-oxopropanal, should be measurable products of isoprene ozonolysis. (C) 2007 Elsevier B.V. All rights reserved.

A great deal of resources has been invested by the semiconductor industry as a whole to make ready 157 nm as the next lithography technology node. Despite of all this effort serious infrastructure issues remain to be solved. Perhaps the first one is the availability of CaF2, but a close second is a suitable soft-pellicle material. It has been previously reported(1-4) that standard 193 nm materials, like Teflon AF(R) and Cytop(R), fail catastrophically upon exposure at 157 nm radiation; and that their transmission is very poor to non-existent. In this paper we report data showing that these materials have higher transmission and lifetimes than previously thought 2. The physical lifetime of Cytop(R) of nearly 500 J/cm(2) is remarkably high, although the transmission varies as a function dose suggesting physical and chemical changes from the onset. For Teflon AF(R) the transmission is a more complex function of exposure dose, suggesting competing mechanisms. From experiments run with PVDF (polyvinyl difluoride), we conclude that the widely reported photodarkening effect is due to the presence of hydrogen in close proximity to a fluorine atom. From IR spectra we conclude that the dioxole moeity in Teflon AF(R) undergoes a series of photochemical reactions that lead to the physical destruction of the polymer.

Twenty five derivatives of the drugs terfenadine and ebastine have been designed, synthesized and evaluated as inhibitors of recombinant human CYP2J2. Compound 14, which has an imidazole substituent, is a good non-competitive inhibitor of CYP2.12 (IC50 – 400 nM). It is not selective towards CYP2.12 as it also efficiently inhibits the other main vascular CYPs, such as CYP2B6, 2C8. 2C9 and 3A4: however, it could be an interesting tool to inhibit all these vascular CYPs. Compounds 4, 5 and 13, which have a propyl, allyl and benzo-1,3-dioxole terminal group, respectively, are selective CYP2J2 inhibitors. Compound 4 is a high-affinity, competitive inhibitor and alternative substrate of CYP2J2 (K-i = 160 50 nM). Compounds 5 and 13 are efficient mechanism-based inhibitors of CYP2J2 (k(inact)/K-i values similar to 3000 L mol(-1) s(-1)). Inactivation of CYP2J2 by 13 is due to the formation of a stable iron-carbene bond which occurs upon CYP2J2-catalyzed oxidation of 13 with a partition ratio of 18 +/- 3. These new selective inhibitors should be interesting tools to study the biological roles of CYP2J2. Published by Elsevier Inc.

Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. 3130-19-6, Name is Bis(7-oxabicyclo[4.1.0]heptan-3-ylmethyl) adipate, SMILES is O=C(CCCCC(OCC1CC2OC2CC1)=O)OCC3CC4OC4CC3, in an article , author is de Guerenu, Anna Lopez, once mentioned of 3130-19-6, Related Products of 3130-19-6.

Lanthanide-doped upconverting nanoparticles (UCNP) are being extensively studied for bioapplications due to their unique photoluminescence properties and low toxicity. Interest in RET applications involving UCNP is also increasing, but due to factors such as large sizes, ion emission distributions within the particles, and complicated energy transfer processes within the UCNP, there are still many questions to be answered. In this study, four types of core and core-shell NaYF4-based UCNP co-doped with Yb3+ and Tm3+ as sensitizer and activator, respectively, were investigated as donors for the Methyl 5-(8-decanoylbenzo[1,2-d:4,5-d ‘]bis([1,3]dioxole)-4-yl)-5-oxopentanoate (DBD-6) dye. The possibility of resonance energy transfer (RET) between UCNP and the DBD-6 attached to their surface was demonstrated based on the comparison of luminescence intensities, band ratios, and decay kinetics. The architecture of UCNP influenced both the luminescence properties and the energy transfer to the dye: UCNP with an inert shell were the brightest, but their RET efficiency was the lowest (17%). Nanoparticles with Tm3+ only in the shell have revealed the highest RET efficiencies (up to 51%) despite the compromised luminescence due to surface quenching.
