Biophysical characterization of KV3.1 potassium channel activating compounds

European Journal of Pharmacology, 2015
The effect of two positive modulators, RE1 and EX15, on the voltage-gated K(+) channel Kv3.1 was investigated using the whole-cell patch-clamp technique on HEK293 cells expressing Kv3.1a. RE1 and EX15 increased the Kv3.1 currents in a concentration-dependent manner with an EC50 value of 4.5 and 1.3µM, respectively. However, high compound concentrations

Toxicology of potassium channel-directed compounds in mosquitoes

NeuroToxicology, 2017
Potential targets for new vector control insecticides are nerve and muscle potassium channels. In this study, the activities of known potassium channel blockers (4-aminopyridine, quinidine, and tetraethylammonium) and the insecticide propoxur were compared to three experimental catechols and several other compounds against Anopheles gambiae and Aedes ...

M2U4O12 compounds of potassium, rubidium and thallium

Journal of Nuclear Materials, 1988
Solid state reactions of M2CO3 (M = K, Rb and Tl) and UO2 with M/U = 0.5 were studied in air and in inert atmosphere at about 900°C. X-ray diffraction studies show that (1) M2U4O13 compounds are formed when the reaction mixture is heated in air and (2) MUO3 phases are obtained in inert atmosphere.

Reaction of Ammonia with Graphite-Potassium Compounds

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1994
Reaction of ammonia vapor with a KC 8 GIC and treatment (vacuum and heating) produces a new second stage GIC: K(NH 3 ) 0.5 C 8 with di=815 pm. The stage 1 GIC can be obtained by reaction with potassium vapor. Similar treatment with KC 24 leads to a stage 2 GIC:K(NH 3 ) 1.3 C 24 with a smaller di=648 pm.

New Graphite Intercalation Compounds : The Potassium Pnictographitides

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1998
Abstract New first stage ternary compounds associating potassium and phosphorous were synthesized in liquid potassium containing a few atomic percent of red phosphorous. The structural arrangement of these alkali metal rich phases was studied by X-Ray diffraction. Electrical measurements parallel and perpendicular to the c-axis were carried out between

Superconductivity in graphite-potassium intercalation compound C8K

Solid State Communications, 1978
Abstract The critical temperature T c , and the angular and temperature dependences of the upper critical field H c2 in highly oriented pseudo-single crystals of C 8 K have been studied by using a magnetic susceptibility measurement. The magnetic susceptibility abruptly changes around 139 mK at zero field.

The stability of potassium-graphite deintercalation compounds

Carbon, 1996
We have synthesized K-GICs (potassium-graphite intercalation compounds) by the modified two-bulb method. The compounds were kept under a stabilization agent (liquid paraffin). The stage transition of K-GDICs (graphite deintercalation compounds), owing to the slow diffusion of water, was observed by X-ray diffraction measurements.
