Ethyl 3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxylate

Acta Crystallographica Section E, 2009
The title compound, C11H9BrClN3O2, is an intermediate in the synthesis of Rynaxypyre, a new insecticidal anthranilic diamide used as a potent and selective ryanodine receptor activator. The dihedral angle between the aromatic ring planes is 78.7 (2)

Rieske iron-sulfur protein induces FKBP12.6/RyR2 complex remodeling and subsequent pulmonary hypertension through NF-κB/cyclin D1 pathway

Nature Communications, 2020
Pulmonary hypertension is a devastating disease with elevation of pulmonary artery pressure and related to abnormal calcium signalling. Here, the authors show that suppression or stabilization of the calcium channel ryanodine receptor 2 may be a ...

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Fluorescent Probes for Insect Ryanodine Receptors: Candidate Anthranilic Diamides

Molecules, 2014
Diamide insecticides with high efficacy against pests and good environmental safety are broadly applied in crop protection. They act at a poorly-defined site in the very complex ryanodine (Ry) receptor (RyR) potentially accessible to a fluorescent probe.

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

Sirtuin signalling governs calcium homeostasis and mitochondrial function in metabolic syndrome cardiomyocytes

Experimental Physiology, EarlyView.
Abstract Metabolic syndrome (MetS) is a major contributor to cardiovascular disease and is characterized by impaired Ca2+ handling and mitochondrial dysfunction in cardiomyocytes. However, the upstream mechanisms linking metabolic stress to these alterations remain incompletely defined.

TMEM16A channel signalling microdomains in the regulation of vascular function

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

The Journal of Physiology, EarlyView.
Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

Update on cellular expression and function of ANO1 channels in urethral smooth muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Activation of ANO1 channels and resulting Cl− efflux are suggested to modulate urethral smooth muscle contractility by enhancing Ca2+ influx via voltage‐dependent Ca2+ entry and resulting contraction in urethral smooth muscle cells.

Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...
