One-pot multicomponent green Hantzsch synthesis of 1,2-dihydropyridine derivatives with antiproliferative activity

Beilstein Journal of Organic Chemistry, 2020
A rapid route for obtaining unsymmetrical 1,2-dihydropyridines (1,2-DHPs) as opposed to 1,4-dihydropyridines (1,4-DHPs) has been achieved via a one-pot multicomponent Hantzsch reaction.

Angiotensin Receptor Blockers Versus Calcium Channel Blockers for First‐Line Antihypertensive Therapy and Survival in Adults Aged 75 Years or Older

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background Evidence guiding first‐line antihypertensive drug choice in adults aged 75 years or older is limited, despite widespread use of angiotensin receptor blockers (ARBs) and calcium channel blockers (CCBs) in late older age. Methods We conducted a target trial emulation using a new‐user design in a nationwide linked healthcare claims ...

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 ...

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Hantzsch Reaction Starting Directly from Alcohols through a Tandem Oxidation Process

Journal of Chemistry, 2017
A Brønsted acidic ionic liquid, 3-(N,N-dimethyldodecylammonium) propanesulfonic acid hydrogen sulphate ([DDPA][HSO4]), has been successfully applied to catalyze sequential oxidation of aromatic alcohols with NaNO3 followed by their condensation with ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Direct Aminolysis of Ethoxycarbonylmethyl 1,4-Dihydropyridine-3-carboxylates

Molecules, 2015
The ethoxycarbonylmethyl esters of 1,4-dihydropyridines were directly converted into carbamoylmethyl esters in the presence of 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) in good to excellent yields under mild conditions.

A Combined MS/MS and IMS Study Into the Fragmentation Pathway of Nifedipine

Journal of Mass Spectrometry, Volume 61, Issue 7, July 2026.
ABSTRACT Collision‐induced dissociation (CID) of small molecules, typically with a molecular mass below 1500 Da, is widely applied for the structural identification of drug metabolites, synthetic by‐products and unknown compounds. Nonetheless, the interpretation of MS/MS spectra derived from protonated or sodiated molecules mainly relies on the ...

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

Medicinal Research Reviews, Volume 46, Issue 4, Page 1173-1229, July 2026.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

Malignant Hyperthermia in Sweden: Clinical Presentations and Genetic Findings

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 6, July 2026.
ABSTRACT Introduction Malignant hyperthermia (MH) is a pharmacogenetic, hypermetabolic and potentially lethal reaction to potent volatile anaesthetics and the muscle relaxant succinylcholine. To improve the understanding of MH, the aim of this retrospective study was to describe the Swedish cohort with respect to clinical manifestations, demographics ...
