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)

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,

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 ...

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.

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.

TMEM16A Ca2+‐activated Cl− channel: Functional interactions with cytoskeletal and membrane‐associated proteins

The Journal of Physiology, EarlyView.
Abstract figure legend The calcium‐activated chloride (ClCa) channel TMEM16A (also known as ANO1) plays critical roles in ion transport, neurotransmission and smooth muscle contraction. Dysregulation of TMEM16A channel activity contributes to the development and progression of various diseases.

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 ...

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

The Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...
