Abstract

Astrocytes function as spatial K+ buffers by expressing a rich repertoire of K+ channels. Earlier studies suggest that acid-sensitive tandem-pore K+ channels, mainly TWIK-related acid-sensitive K+ (TASK) channels, mediate part of the passive astroglial membrane conductance. Here, using a combination of electrophysiology and pharmacology, we investigated the presence of TASK-like conductance in hippocampal astrocytes of rat brain slices. Extracellular pH shifts to below 7.4 (or above 7.4) induced a prominent inward (or outward) current in astrocytes in the presence of tetrodotoxin, a Na+ channel blocker, and 4,4′-diisothiocyanatostilbene-2,2’-disulfonate, a co-transporter blocker. The pH-sensitive current was insensitive to quinine, a potent blocker of tandem-pore K+ channels including TWIK-1 and TREK-1 channels. Voltage-clamp analysis revealed that the pH-sensitive current exhibited weak outward rectification with a reversal potential of −112 mV, close to the Nernst equilibrium potential for K+. Furthermore, the current–voltage relationship was well fitted with the Goldman–Hodgkin–Katz current equation for the classical open-rectifier ‘leak’ K+ channel. The pH-sensitive K+ current was potentiated by TASK channel modulators such as the volatile anesthetic isoflurane but depressed by the local anesthetic bupivacaine. However, unlike TASK channels, the pH-sensitive current was insensitive to Ba2+ and quinine. Thus, the molecular identity of the pH-sensitive leak K+ channel is unlikely to be attributable to TASK channels. Taken together, our results suggest a novel yet unknown leak K+ channel underlying the pH- and anesthetic-sensitive background conductance in hippocampal astrocytes. [ABSTRACT FROM AUTHOR]

43. Effect of inorganic salts on the inhibition of hydrolyzing halo-ester in a two-phase solution

Author

Abstract

Effect of the inorganic salts on the conversion of halo-ester (ethyl-2-bromoisobutyrate, EtOBuBr) hydrolyzing in an alkaline aqueous solution/organic solvent two-phase medium was investigated. The rate of hydrolyzing EtOBuBr and the conversion are obviously affected by the inorganic salts. The experimental data verify the proposed mechanism of hydrolysis. The reaction steps which hydrolyze these bromo-alkyl bonds (Br-C bond) and ester functional groups (-COOR) are developed and discussed. A kinetic model of the main reaction steps was established in which the rate expressions were derived. The intrinsic rate constants of the reactions were determined from the experimental data of EtOBuBr hydrolysis via parameter estimation. The results indicated that the conversion of hydrolyzing EtOBuBr is highly dependent on the concentration of alkaline compound in the aqueous solution. It is also found that sodium carbonate, sodium chloride, sodium nitrate and sodium sulfate inhibit the reaction, while calcium carbonate enhances it. The corresponding rate constants of hydrolyzing EtOBuBr in a variety of inorganic salt concentrations were searched.
