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

open access: yesJournal 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 ...

Histamine H3 receptor inverse agonists/antagonists influence intra-regional cortical activity and inter-regional synchronization during resting state: an exploratory cortex-wide imaging study in mice [PDF]

open access: yesMolecular Brain
The histaminergic system plays a key role in modulating learning and memory, wakefulness, and energy balance. Histamine H3 receptors constitutively inhibit the synthesis and release of histamine and other neurotransmitters. Therefore, H3 receptor inverse

Structural insights into the agonists binding and receptor selectivity of human histamine H4 receptor

open access: yesNature Communications, 2023
Histamine is a biogenic amine that participates in allergic and inflammatory processes by stimulating histamine receptors. The histamine H4 receptor (H4R) is a potential therapeutic target for chronic inflammatory diseases such as asthma and atopic ...
