Effects of membrane transport activity and cell metabolism on the unbound drug concentrations in the skeletal muscle and liver of drugs: A microdialysis study in rats. [PDF]

open access: yesPharmacol Res Perspect, 2021
Unbound concentrations of of 14 commercial drugs in rat liver, muscle, and blood Abstract The unbound concentrations of 14 commercial drugs, including five non‐efflux/uptake transporter substrates—Class I, five efflux transporter substrates—class II and four influx transporter substrates—Class III, were simultaneously measured in rat liver, muscle, and

Positive chronotropic action of HCN channel antagonism in human collecting lymphatic vessels. [PDF]

open access: yesPhysiol Rep, 2022
Hyperpolarisation‐activated cyclic‐nucleotide gated (HCN) channels primarily determine sinoatrial pacemaking. In human lymphatic vessels HCN channel proteins are also expressed but have a negligible functional role in ex vivo phasic activity when investigated using the HCN inhibitors ivabradine, ZD7288 and caesium.

The role of endocardial endothelium in the effect of histamine on myocardial contractions of histamine H1 and H2 receptor blockade [PDF]

open access: yesPraxis Medica, 2016
Endocardial endothelium (EE) is a barrier which controls the passage of macromolecules and fluids between the blood and the adjacent miocardial interstitium. At the same time it is the place of synthesis of numerous endothelial mediators. Histamine as an

Analytical and Pharmacological Characterization of 1-(Furan-2-Carbonyl)-LSD (1F-LSD) and Comparison With 1-(Thiophene-2-Carbonyl)-LSD (1T-LSD). [PDF]

open access: yesDrug Test Anal
The novel lysergamide 1‐(furan‐2‐carbonyl)‐LSD (1F‐LSD) was analytically characterized. 1F‐LSD showed LSD‐like activity in vivo similar to 1‐(thiophene‐2‐carbonyl)‐LSD (1T‐LSD) used for comparison. Administration studies in mice and LC–MS analysis revealed that 1F‐LSD served as a prodrug.

The Concise Guide to PHARMACOLOGY 2023/24: G protein-coupled receptors

open access: yesBritish Journal of Pharmacology, Volume 180, Issue S2, Page S23-S144, October 2023., 2023
The Concise Guide to PHARMACOLOGY 2023/24 is the sixth in this series of biennial publications. The Concise Guide provides concise overviews, mostly in tabular format, of the key properties of approximately 1800 drug targets, and about 6000 interactions with about 3900 ligands.

Improved PIEZO1 agonism through 4‐benzoic acid modification of Yoda1

open access: yesBritish Journal of Pharmacology, Volume 180, Issue 16, Page 2039-2063, August 2023., 2023
Background and Purpose The protein PIEZO1 forms mechanically activated, calcium‐permeable, non‐selective cation channels in numerous cell types from several species. Options for pharmacological modulation are limited and so we modified a small‐molecule agonist at PIEZO1 channels (Yoda1) to increase the ability to modulate these channels.

Association of Inpatient Prescribing of First-Generation Antihistamines With Delirium in Older Adults: A Cross-Sectional Study. [PDF]

open access: yesJ Am Geriatr Soc
ABSTRACT Background Small studies have reported associations between first‐generation antihistamines and delirium. It is unclear whether first‐generation antihistamines cause clinically important delirium among older adult inpatients. Objective To estimate the association between inpatient physician prescribing of first‐generation antihistamines and ...

Allergen‐free extracts from birch, ragweed, and hazel pollen activate human and guinea‐pig submucous and spinal sensory neurons

open access: yesNeurogastroenterology &Motility, Volume 35, Issue 7, July 2023., 2023
Low molecular extracts from birch, ragweed, and hazel pollen strongly excite enteric and DRG neurons. Nerve activation was mediated by histamine in birch and ragweed, but not in hazel pollen extracts. Abstract Background Non‐allergenic, low molecular weight components of pollen grains are suspected to trigger changes in gut functions, sometimes leading

The transport function of the human lymphatic system—A systematic review

open access: yesPhysiological Reports, Volume 11, Issue 11, June 2023., 2023
Abstract Physiological properties and function of the lymphatic system is still somewhat of a mystery. We report the current knowledge about human lymphatic vessel contractility and capability of adaptation. A literature search in PubMed identified studies published January 2000–September 2022.

Critical role of mitogen‐inducible gene 6 in restraining endothelial cell permeability to maintain vascular homeostasis

open access: yesJournal of Cell Communication and Signaling, Volume 17, Issue 1, Page 151-165, March 2023., 2023
Graphical abstract Xing et al. (2022) investigated the critical role of MIG6 in vascular permeability. MIG6 deficiency promotes VEGFA‐induced vascular permeability via activation of PLCγ1‐Ca2+‐eNOS signaling and perturbation of the balance in RAC1/RHOA activation, resulting in endothelial barrier disruption.
