Blocking Histamine H1 Improves Learning and Mnemonic Dysfunction in Mice With Social Isolation Plus Repeated Methamphetamine Injection

Journal of Pharmacological Sciences, 2008
The aim of this study was to investigate the effects of histamine H1 and H3 antagonists on learning and mnemonic dysfunction in mice. Two H1 antagonists, pyrilamine and clozapine, and the prototypic H3 antagonist thioperamide were used to study the role ...

Histamine release after injection of benzodiazepines and of etomidate. A problem associated with the solvent propylene glycol (= Libération d'histamine après injection de benzodiazépines et d'étomidate. Rôle du solvant propylène-glycol) [PDF]

, 1993
Many drugs, especially when given in rapid sequence can cause histamine release. Ten healthy volunteers were premedicated with diazepam 10 mg.70 kg-1 i.v. and lormetazepam 1 mg.70 kg-1 i.v., respectively, 30 min prior to etomidate 0.15 mg.kg-1 i.v.

Von In‐Silico bis In‐Cerebro – Entwicklung des Orexinrezeptor Antagonisten „Photorexant“ zur Photomodulation In Vitro und im Gehirn der Maus

Angewandte Chemie, EarlyView.
Durch einen strukturbasierten Designansatz wurden photoschaltbare Derivate des von der FDA zugelassenen Arzneistoffes Suvorexant entwickelt, gedockt, synthetisiert und pharmakologisch an den Orexin‐1‐ und 2‐Rezeptoren (OX1R und OX2R) charakterisiert.

In Silico to In Cerebro—Development of the Orexin Receptor Antagonist “Photorexant” for Photomodulation In Vitro and in Mouse Brains

Angewandte Chemie International Edition, EarlyView.
Following a structure‐based design approach, photoswitchable derivatives of the FDA‐approved drug suvorexant were designed, docked, synthesized, and characterized pharmacologically at the orexin 1 and 2 receptors (OX1R and OX2R). Optimized “photorexant” showed up to an 11‐fold difference in IC50 between photoisomers, enabled dynamic and reversible ...

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Clozapine:norclozapine ratio as a marker of metabolic risk and therapeutic response and effect of valproate on clozapine levels

British Journal of Clinical Pharmacology, EarlyView.
Aims Clozapine is the most effective antipsychotic in treatment‐resistant schizophrenia. Clozapine causes weight gain and increased diabetes risk. The role of its metabolite norclozapine and clozapine:norclozapine ratio (CLZ/NCLZ) in metabolic effects has been debated.

Activation of carbonic anhydrase isoforms involved in modulation of emotional memory and cognitive disorders with histamine agonists, antagonists and derivatives

Journal of Enzyme Inhibition and Medicinal Chemistry, 2021
Carbonic anhydrases (CAs, EC 4.2.1.1) activators were shown to be involved in memory enhancement and learning in animal models of cognition. Here we investigated the CA activating effects of a large series of histamine based compounds, including ...
