There has been considerable interest in using bumetanide, a diuretic chloride importer NKCC1 antagonist, to reduce intracellular chloride ([Cl(-)](i)) in epileptic neurons, thereby shifting the polarity of GABA from excitatory to inhibitory and ameliorating the actions of GABA-acting antiepileptic drugs. However, a recent study raises the important issue of potential deleterious actions of bume...

The mol-ecular structure of the title compound, trans-[Cu(C2H)Cl(C26H24P2)2], consists of an Ru(II) cation, located on an inversion centre, in an octa-hedral environment defined by two chelating phosphines, one acetyl-ide and one chloride ligand. The -C CH and the chlorine ligands are disordered over two equivalent positions (0.5 occupancy each). The coordination geometry is distorted octa-hedr...

In the title complex, [CuCl(2)(C(24)H(24)N(2)O(2))], the Cu(II) cation is N,N',O-chelated by a 2,2'-(1,1'-binaphthyl-2,2'-diyldiimino)-diethanol ligand and coordinated by two chloride anions in a distorted square-pyramidal geometry. In the diethanol ligand, the two naphthalene ring systems are twisted with respect to each other at a dihedral angle of 68.30 (9)°. The uncoord-inated hy-droxy grou...

Brush border membrane vesicles were isolated from rabbit renal cortex by Mg(++)-precipitation and differential centrifugation. (36)Cl(-) and [(3)H]glucose uptakes were simultaneously determined by a rapid filtration technique. Lysis of the vesicles with distilled water abolished 90-95% of the radioactivity on the filters, suggesting that nearly all of the (36)Cl(-) and [(3)H]glucose counts repr...

1,2-Dichloro-3,3,4,4,5,5-hexafluorocyclopentene (F 6 cypCl 2 ) was functionalized with diphenyl- and dimesitylphosphanyl groups by a salt-elimination reaction of the respecttive chlorophosphane (PPh Cl, PMes Cl) in situ generated lithiated F cyp(Li)Cl. cyp(PR )Cl (R = Ph, Mes) functionalised again to obtain corresponding trimethylstannyl substituted compounds )(SnMe 3 Mes). These tin-precursors...

We present the first report of optical absorption spectroscopy H$^{36}\!$Cl, a radioactive isotopologue hydrogen chloride. used Fourier-transform infrared to determine line center wavenumbers fundamental rovibrational band lines P(10)-R(10) and overtone P(1)-R(7) with total uncertainty less than 0.0018 cm$^{-1}$ (60 MHz) 0.007 (0.2 GHz), respectively, at 68 % confidence level. also performed ro...

Chloride (Cl(-)) homeostasis is known to be fundamental for central nervous system functioning. Alterations in intracellular Cl(-) concentration ([Cl(-)]i) and changes in the efficacy of Cl(-) extrusion are involved in numerous neurological disorders. Therefore, there is a strong need for studies of the dynamics of [Cl(-)]i in different cell types under physiological conditions and during patho...

The rabbit cortical collecting duct (CCD) exhibits the capacity for active chloride absorption when basolateral Na-K-ATPase is inhibited by ouabain. The present studies examine the contribution of H,K-ATPase to this ouabain-insensitive Cl absorption and to related ion fluxes. Rabbits were fed a KCl-rich diet with no measurable Na for 4 to 13 d before isolation of the CCD for microperfusion. App...

In the title compound, C(6)H(10)N(6)S(2) (2+)·2Cl(-)·CH(3)OH, the pyrid-azine ring is almost planar, the greatest deviation from the mean plane being 0.025 (2) Å for one of the ring N atoms. The two thiouronium substituents are tilted out of this plane by 60.87 (6) and 57.94 (7)°. The thiouronium cations and the chloride anions are linked by strong N-H⋯Cl hydrogen bonds. The methanol solvent mo...

In the title compound, [CuCl(2)(C(8)H(9)N(3)O)], the Cu(II) atom has a distorted square-pyramidal CuCl(2)N(2)O coordination geometry. The tridentate acetohydrazide ligand occupies three basal positions, the fourth basal position being defined by a chloride anion at a distance of 2.2116 (6) Å. The second chloride anion is in the apical position and forms a longer Cu-Cl distance of 2.4655 (7) Å. ...
