The effects of anisole (methoxybenzene) and veratrole (1,2-dimethoxybenzene) on the resting membrane potential (RMP), action potential (AP) and membrane potassium currents were investigated in snail neurons under current- and voltage-clamp conditions. Anisole (0.9-3 mM) scarcely influenced the AP, but it

Definitive X-ray crystallographic evidence is obtained for a single hole (or a polaron) to be uniformly distributed on the three equivalent 1,2-dimethoxybenzenoid (or veratrole) rings in the hexamethoxytriptycene cation radical. This conclusion is further supported by electrochemical analysis and by

Several 5,10-dihydroindeno[1,2-b]indole derivatives incorporating methoxy, hydroxyl, and halogen (F, Cl, and Br) moieties on the indene fragment of the molecule were prepared and tested against five carbonic anhydrase (CA, EC 4.2.1.1) isoforms. The inhibitory potencies of these compounds against the

Diselenides are known precatalysts for catalytic oxidations. The use of these widely available compounds as catalysts for the oxidation of alcohols was investigated, still leaving many mechanistic questions to be answered. By using a range of analytical techniques, we found

Carbonic anhydrases (CAs, EC 4.2.1.1) are inhibited by sulfonamides, inorganic anions, phenols, coumarins (acting as prodrugs) and polyamines. A novel class of CA inhibitors (CAIs), interacting with the CA isozymes I, II (cytosolic) and IX, XII (transmembrane, tumor-associated) in a

Mature gregarious male desert locusts, Schistocerca gregaria, emit the courtship inhibition pheromone phenylacetonitrile. Wings and legs, in particular the fore wings, have been identified as the main releasing sites. Abdomen and head emit only trace amounts of this pheromone. In

Silene latifolia and its pollinator, the noctuid moth Hadena bicruris, represent an open nursery pollination system wherein floral volatiles, especially veratrole (1, 2-dimethoxybenzene), lilac aldehydes, and phenylacetaldehyde are of key importance for floral signaling. Despite the important role of floral

The anaerobic veratrol O-demethylase mediates the transfer of the methyl group of the phenyl methyl ether veratrol to tetrahydrofolate. The primary methyl group acceptor is the cobalt of a corrinoid protein, which has to be in the +1 oxidation state

Thermal degradation of levoglucosan (1,6-anhydro-beta-D-glucopyranose) was shown to be substantially suppressed in the presence of some aromatic compounds under the conditions of N2/240-340 degrees C/15 min. This stabilization effect is also discussed with CH-pi interaction between levoglucosan and pi-electrons in

Flower odors are important signals for chemical communication between plants and flower visitors. Here, we studied the naive responses of Culex pipiens pipiens biotype molestus Forskal 1775 (Diptera: Culicidae) to typical flower odors and assessed the learning capacity of mosquitoes

The mechanism of the anti-inflammatory action of phenolic compounds was examined using neutrophil chemotaxis. Chemotactic activity of guinea pig peritoneal neutrophils to N-formylmethionyl-leucylphenylalanine (FMLP) was suppressed in a concentration-dependent manner. The order of drug potency in inhibiting the neutrophil chemotaxis

We applied two-color resonant two-photon mass-analyzed threshold ionization (MATI) spectroscopy to investigate the molecular properties of the selected rotamers of o-dimethoxybenzene (ODMB) and m-dimethoxybenzene (MDMB). The present experimental results show that only one stable configuration is involved in the photoexcitation

The lignin models anisole, 1,2-dimethoxybenzene, 1,4-dimethoxybenzene, and 1,3,5-trimethoxybenzene were reacted with ozone in aqueous solution, and major products were identified and quantified with respect to ozone consumption when reference material was available. Hydroxylation products in yields equivalent to those of

From 3-methoxyphenol-grown cells of Acetobacterium dehalogenans, an inducible enzyme was purified that mediated the transfer of the methyl groups of veratrol (1,2-dimethoxybenzene) to a corrinoid protein enriched from the same cells. In this reaction, veratrol was converted via 2-methoxyphenol to

The anaerobic cleavage of ether bonds of methoxylated substrates such as vanillate or veratrol in acetogenic bacteria is mediated by multi-component enzyme systems, the O-demethylases. Acetobacterium dehalogenans harbours different inducible O-demethylases with various substrate spectra. Two of these enzyme systems

The absorption rates of 4-bromophenol, 2,4-dibromophenol, 3,4,5-trichloroguaiacol, and tetrachloroveratrol across fish gill epithelium have been measured in a perfused gill preparation from rainbow trout (Oncorhynchus mykiss). In additional experiments the absorption rate of tetrachloroveratrol was measured in free swimming fish.

[reaction: see text]. A protocol for performing Rh catalyzed aromatic borylations in cyclohexane has been devised. Borylation at the 5-position of several 1,3-substituted aromatic species ranging from electron-rich (1,3-(NMe(2))(2)C(6)H(4)) to electron-deficient (1,3-(CF(3))(2)C(6)H(4)) yields the corresponding aryl boronate esters. Veratrole was
