Pharmacogenetics of Potassium Channel Blockers [PDF]
The QT interval on surface electrocardiograms provides a model of a multicomponent integrated readout of many biological systems, including ion channels, modulatory subunits, signaling systems that modulate their activity, and mechanisms that regulate the expression of their responsible genes.

Pulmonary vasoconstrictor action of KCNQ potassium channel blockers [PDF]
Background KCNQ channels have been widely studied in the nervous system, heart and inner ear, where they have important physiological functions. Recent reports indicate that KCNQ channels may also be expressed in portal vein where they are suggested to ...

Proarrhythmic and Torsadogenic Effects of Potassium Channel Blockers in Patients. [PDF]
The most common arrhythmia requiring drug treatment is atrial fibrillation (AF), which affects 2 to 5 million Americans and continues to be a major cause of morbidity and increased mortality. Despite recent advances in catheter-based and surgical therapies, antiarrhythmic drugs continue to be the mainstay of therapy for most patients with symptomatic ...

Photochromic potassium channel blockers: design and electrophysiological characterization. [PDF]
Voltage-gated potassium (K v) channels are membrane proteins that open a selective pore upon membrane depolarization, allowing K(+) ions to flow down their electrochemical gradient. In neurons, K v channels play a key role in repolarizing the membrane potential during the falling phase of the action potential, often resulting in an after ...

Identification of cellular ion channels that facilitate Hazara nairovirus infection enables selection of clinically approved compounds with anti-nairoviral properties [PDF]
The Nairoviridae family of segmented negative-sense RNA viruses includes the serious human pathogen Crimean-Congo haemorrhagic fever virus (CCHFV), associated with a case/fatality rate of up to 40% for which no approved vaccines or treatments exist ...

Palmitic acid reduces cytosolic potassium and induces IL-1β production in lipopolysaccharide-primed human macrophages [PDF]
Saturated fatty acids, particularly palmitic acid (PA), promote inflammation and contribute to chronic diseases such as type 2 diabetes and cardiovascular disease.

Сardioprotective agents with biaromatic structure. Part 5. Potassium Kv1.5-channels blockers
The Kv1.5 potassium channel provides an ultra-rapid delayed rectifier potassium current, IKur, that acts selectively in human atrial cells. This makes selective Kv1.5 blockade a promising approach to control atrial arrhythmias without the adverse ...

Role of the potassium channels in vasorelaxant effect of asafoetida essential oil [PDF]
Objective: In a previous work, we showed that asafoetida essential oil (AEO), from oleo-gum resin of Ferula asafoetida L. from the Apiaceae family, has a vasodilatory effect. This effect was both endothelium-dependent and endothelium-independent.
