The Impact of H1–H4 Receptor Antagonists on the Levels of Selected Oxidative Stress Markers in Liver and Muscle Tissue in an Animal Model of Colitis [PDF]
Background/Objectives: The global prevalence and incidence of inflammatory bowel diseases have risen in the past two decades. Among them, Crohn’s disease and ulcerative colitis are still challenging to treat due to vascular and proliferative alterations.

Function and Role of Histamine H1 Receptor in the Mammalian Heart [PDF]
Histamine can change the force of cardiac contraction and alter the beating rate in mammals, including humans. However, striking species and regional differences have been observed. Depending on the species and the cardiac region (atrium versus ventricle)

Novel chalcone-based fluorescent human histamine H 3 receptor ligands as pharmacological tools [PDF]
Novel fluorescent chalcone-based ligands at human histamine H(3) receptors (hH(3)R) have been designed, synthesized, and characterized. Compounds described are non-imidazole analogs of ciproxifan with a tetralone motif.

Histamine elicits glutamate release from cultured astrocytes
Astrocytes play key roles in regulating brain homeostasis and neuronal activity. This is, in part, accomplished by the ability of neurotransmitters in the synaptic cleft to bind astrocyte membrane receptors, activating signalling cascades that regulate ...

Histamine and migraine revisited: mechanisms and possible drug targets
Objective To review the existing literature on histamine and migraine with a focus on the molecule, its receptors, its use in inducing migraine, and antihistamines in the treatment of migraine. Background Histamine has been known to cause a vascular type

Catalytic Enantioselective Intramolecular Aza‐Michael Addition to α,β‐Unsaturated Esters
A general method for accessing enantioenriched saturated N‐heterocycles via a catalytic enantioselective intramolecular aza‐Michael reaction to α,β‐unsaturated esters is described. A superbasic bifunctional iminophosphorane (BIMP) catalyst was key to enabling reactivity of the high pKa sulfonamide pronucleophile, whilst delivering good to excellent ...

Histamine: A Mediator of Intestinal Disorders—A Review
Within the gastrointestinal tract, histamine is present at relatively high concentrations, especially during inflammatory processes. Histamine is a biogenic amine with numerous effects on many cell types, mediated by the activation of its four different ...

Structure of the human histamine H1 receptor gene [PDF]
Histamine H1 receptor expression has been reported to change in disorders such as allergic rhinitis, autoimmune myocarditis, rheumatoid arthritis and atherosclerosis. Here we report the isolation and characterization of genomic clones containing the 5´ flanking (regulatory) region of the human histamine H1 receptor gene. An intron of approx. 5.8 kb was
