Effect of 5-{3-[((2S)-1,4-benzodioxan-2-ylmethyl)amino]propoxy}-1,3-benzodioxole HCl (MKC-242), a novel 5-HT1A-receptor agonist, on aggressive behavior and marble burying behavior in mice

Behavioral effects of 5-{3-[((2S)-1,4-benzodioxan-2ymethyl)amino]propoxy}-1,3-benzo- dioxole HCI (MKC-242), a novel 5-HT1A-receptor agonist, were evaluated using animal models of anxiety and obsessive compulsive disorder and compared against reference compounds. MKC-242 suppressed foot shock-induced fighting behavior without loss of motor coordination in mice as the reference compounds did. The ED50 values of MKC-242, buspirone, tandospirone and diazepam were 1.7, 42, 80 and 2.0 mg/kg, p.o., respectively. The duration of the suppression of fighting by MKC-242 was longer than those of buspirone and tandospirone and comparable to that of diazepam. Similar results were also obtained with the water-lick conflict test in rats. The plasma concentration of MKC-242 in rats was much higher than the reported value of buspirone during 0.25-6 hr after oral administration. In addition, MKC-242 reduced marble burying behavior without reduction of motor activity. Fluoxetine, tandospirone and diazepam also reduced the behavior at non-sedative doses. These findings indicate that MKC-242 possesses a longer-lasting anxiolytic effect than azapirones. This might be due to the high concentration of the compound in plasma. In addition, it is also suggested that MKC-242 possesses an antiobsessional effect.

Collagen modified with epoxidized safrole for improving antibacterial activity

An epoxidized safrole, 5-(oxiran-2-ylmethyl)-benzo[d][1,3] dioxole (OYBD), was synthesized and employed to modify collagen for improving its antibacterial activity. The interaction between collagen and OYBD, and the structure/properties of the modified collagen were investigated in detail. The results indicated that the OYBD-modified collagen showed a higher de-nature temperature (Td, 90.2 degrees C), improved hydrophobic properties (contact angle from 84.2 degrees to 89.1 degrees) and enhanced tensile strength (6.2-11.0%) without destroying its triple helix structure. From observation of scanning electron microscopy (SEM), a higher density of intertwining morphology and a more stable network structure were observed, which was consistent with improved tensile strength and reduced breaking extension stress. The antibacterial test and LIVE/DEAD Baclight bacterial viability assay illustrated that the modified collagen exhibited excellent antibacterial activity to both Gram-negative and Gram-positive bacteria. Furthermore, the OYBD-modified collagen still exhibited cytocompatibility, supporting human fibroblast proliferation, which holds a great potential for developing antibacterial collagen-based biomaterials.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 526-95-4, in my other articles.

The ring-puckering potential energy function and theoretical calculations for silacyclopent-2-ene-d(0) and 1,1-d(2) and the difluoro and dichloro derivatives

High level ab initio and DFT calculations have been carried out for silacyclopent-2-ene and its 1,1-d(2), 1,1-difluoro, and 1,1-dichloro derivatives. The previously published far-infrared spectra of the ring-puckering vibration, which had been interpreted to be characteristic of a rigid planar molecule, have been reanalyzed for the hydride and 1,1-d(2) derivative. Both the spectra and the theoretical calculations show the molecule to have a small barrier to planarity. The experimental data analyzed with a Gaussian barrier produce a barrier of 49 cm(-1) as compared to a value of 47 cm(-1) computed using the CCSD/6-311++G(d,p) basis set. The experimental value for the deuteride was determined to be 41 cm(-1) from the one-dimensional approximation. All MP2 and DFT computations for the 1,1-difluoro derivative predict a planar structure whereas the MP2 computation when used with triple-zeta basis set predicts a barrier of 13 cm(-1) for the chloride. Vibrational frequencies were also computed for these molecules and compared to experimental results for the characteristic frequencies for these types of molecules. (c) 2007 Elsevier Inc.

Experimental and Computational Evaluation of Piperonylic Acid Derived Hydrazones Bearing Isatin Moieties as Dual Inhibitors of Cholinesterases and Monoamine Oxidases

A set of piperonylic acid derived hydrazones with variable isatin moieties was synthesized and evaluated for their inhibitory activity against the enzymes acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and monoamine oxidases A and B (MAO-A/B). The results of in vitro studies revealed IC50 values in the micromolar range, with the majority of the compounds showing selectivity for the MAO-B isoform. N-[2-Oxo-1-(prop-2-ynyl)indolin-3-ylidene]benzo[d][1,3]dioxole-5-carbohydrazide (3) was identified as a lead AChE inhibitor with IC50=0.052 +/- 0.006 mu m. N-[(3E)-5-chloro-2-oxo-2,3-dihydro-1H-indol-3-ylidene]-2H-1,3-benzodioxole-5-carbohydrazide (2) was the lead MAO-B inhibitor with IC50=0.034 +/- 0.007 mu m, and showed 50 times greater selectivity for MAO-B over MAO-A. The kinetic studies revealed that compounds 2 and 3 displayed competitive and reversible inhibition of AChE and MAO-B, respectively. The molecular docking studies revealed the significance of hydrophobic interactions in the active site pocket of the enzymes under investigation. Further optimization studies might lead to the development of potential neurotherapeutic agents.

Study on the Electrical Conductive Mechanism in the Five-layered Structure of Organic Light-emitting Diodes

The Electrical conductive mechanism was studied using a five-layered structure of organic light-emitting diodes. The manufactured device structure was ITO/2,2-bistrifluoromethyl-4,5-difluoro-1,3-dioxole (AF)/N,N’-diphenyl-N,N’bis(3-methylphenyl)-1,1′-biphenyl-4,4′-diamine(TPD)/tris(8-hydroxyquinoline)aluminum (Alq(3))/(2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP)/LiF/Al. From the analysis of the current density-luminance-voltage characteristics of the five-layered device, four conductive mechanisms depending on the applied voltage region were found. In the Schottky region, where the electric field E is below 1.6 x 10(5) V/cm, the obtained Schottky coefficient beta(ST) is 3.98 x 10(-24) JV(-1/2)m(1/2). In the negative-resistance region, where the electric field is below 3.7 x 10(5) V/cm, the current density J is proportional to E(-2.41), In the Poole-Frenkel region, where the electric field is below 6.4 x 10(5) V/cm, the obtained Poole-Frenkel coefficient beta(P F) is 7.80 x 10(-24) JV(-1/2)m(1/2). The experiment obtained value of beta(P F) corresponds to 1.96 times that of beta(ST), which is theoretically expected because beta(P F) = 2 beta(ST). In the Folwer-Nordheim region, where the electric field is above 8.30 x 10(5) V/cm, the obtained potential barrier empty set(F N) is 0.42 eV.

Gas permeation in poly(ether imide) nanocomposite membranes based on surface-treated silica. Part 2: With chemical coupling to matrix

Nanocomposite membranes based on nano-sized SiO2 particles with chemical coupling to the polymer matrix are described with special emphasis on gas permeation properties. In this paper, poly(ether imide) with reactive imide rings in the backbone was used as the matrix to which the SiO2 particles were chemically bonded via an amine-containing silane coupling agent. Four types of nanocomposite membranes were prepared by solution casting and melt processing and characterized in terms of morphology and void volume formed due to adding SiO2 particles. The relative gas permeability of the nanocomposite with chemical coupling to matrix was decreased by the presence of SiO2 particles. Diffusion coefficients computed from time lag data also decreased with SiO2 content. However, solubility coefficients computed by dividing the experimental permeability by the diffusivity obtained from the observed time lag increased with SiO2 content contrary to simple composite theory. These permeation properties are discussed in terms of the void volume fraction estimated by density observations. In addition, TEM and SEM were used to explore the morphology of these nanocomposite membranes. (c) 2006 Elsevier Ltd. All rights reserved.

Gas Permeation and Hemocompatibility of Novel Perfluorinated Polymers for Blood Oxygenation

Gas permeation properties of three highly permeable perfluorinated polymers (polyhexafluoropropylene (PHFP), amorphous Teflon AF2400, and polyperfluoro(2-methyl-2-ethyl-dioxole-1,3) (PPFMED)), which are promising materials for the dense thin layer of hollow fiber membranes for extracorporeal membrane oxygenation have been studied using nitrogen, oxygen, and carbon dioxide. Hemocompatibility of the polymeric films has also been investigated on whole blood from healthy donors. Gas permeation of the polymers increases in the order PHFP < PPFMEDD < AF2400, with PHFP alone having the permeability coefficients of the gases do not below those of polydimethylsiloxane applied as the selective layer of blood oxygenation membranes. Hemocompatibility of the polymers declines in the order PHFP > PPFMED > AF2400, with the most permeable polymer AF2400 exhibiting the worst hemocompatibility among the other polymers studied. Polyperfluoro(2-methyl-2-ethyl-dioxole-1,3) is shown to be the most appropriate polymer to fabricate hollow fiber membranes for blood oxygenation.

Enhanced flow injection analysis for measurements of S-nitrosothiols species in biological samples using highly selective amperometric nitric oxide sensor

A highly selective nitric oxide (NO) sensor is fabricated and applied to devise an enhanced flow injection analysis (FIA) system for S-nitrosothiols (RSNOs) measurement in biological samples. The NO sensor is prepared using a polytetrafluoroethylene (PTFE) gas-permeable membrane loaded with Teflon AF (R) solution, a copolymer of tetrafluoroethylene and 2,2-bis(trifluoroethylene)-4,5-difluoro-1,3-dioxole, to improve selectivity. This method is much simpler and possesses good performance over a wide range of RSNOs concentrations. Standard deviation for three parallel measurements of blood plasma is 4.0%. The use of the gas sensing configuration as the detector enhances selectivity of the FIA measurement vs. using less selective electrochemical detectors that do not use PTFE/Teflon type outer membranes.

Nuclear Spin Selective Torsional States: Implications of Molecular Symmetry

We consider a class of molecules with C-2 symmetry axis and three segments A, B, C which can rotate independently about that axis, corresponding to two independent torsions (B vs. A and C vs. B). The torsions may be feasible either in the electronic ground or in the excited states. We determine the corresponding molecular symmetry group, i.e. the Abelian group G(16)(A) representing 16 feasible permutations and permutation-inversions, and its permutation subgroup with eight permutations, together with their properties, e.g. their character tables and the corresponding 16 or 8 irreducible representations (IREPs), respectively. Accordingly, the molecules which belong to this class have at most eight different nuclear spin isomers (NSIs). A subset of them survives at low temperature, T -> 0. The corresponding NSI selective wavefunctions contain products of torsional times nuclear wavefunctions with specific IREPs. The NSIs are characterized by these IREPs. As an example, we determine the molecular symmetry adapted torsional wavefunctions of the model 2-[4-(cyclopenta-2,4-dien-1-ylidene)cyclohexa-2,5-dien-1-ylidene]-2H-1,3-dioxole, abbreviated as CCD. In order to demonstrate the principles of the derivations, we employ a simple model, with the C-2 symmetry axis oriented along the laboratory Z-axis, and with all degrees of freedom frozen in the equilibrium structure of CCD, except the two torsional degrees of freedom. The resulting torsional wavefunctions represent different NSIs of CCD, ready for subsequent applications, e.g. for demonstrations of NSI selective dynamics.
