Revisiting Preclinical Observations of Several Histamine H3 Receptor Antagonists/Inverse Agonists in Cognitive Impairment, Anxiety, Depression, and Sleep–Wake Cycle Disorder [PDF]
A relationship appears to exist between dysfunction of brain histamine (HA) and various neuropsychiatric brain disorders. The possible involvement of brain HA in neuropathology has gained attention recently, and its role in many (patho)physiological ...

Non-imidazole heterocyclic histamine H3 receptor antagonists
Continued exploration of the SAR around the lead imidazopyridine histamine H(3) antagonist 1 has led to the discovery of several related series of heterocyclic histamine H(3) antagonists. The synthesis and SAR of indolizine, indole and pyrazolopyridine based compounds are now described.

Activity-restoring mutations in the histamine H<sub>3</sub> receptor increase constitutive activity and reduce structural stability. [PDF]
Abstract The histamine H3 receptor (H3R) is a class A G protein‐coupled receptor (GPCR) that regulates neurotransmitter release in the central nervous system. Although structures of H3R in both inactive and active states have been elucidated, the functional roles of specific residues remain unclear.

Pitolisant Inhibits Alcohol Drinking and Improves Withdrawal Negative Affect Through Lateral Habenula Histaminergic Signaling in Mice. [PDF]
Pitolisant, an FDA‐approved H3R antagonist, counteracts the rewarding and sedative effects of ethanol, reduces alcohol intake, and alleviates the negative affect during withdrawal. This might occur via the antagonism of presynaptic autoreceptors and heteroreceptors H3Rs in the lateral habenula, thereby activating the H2R/p‐CREB/BDNF signaling and ...

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]
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

Neurotransmitters and Immunity: Molecular Mechanisms, Biological Functions, Diseases, and Potential Therapeutic Targets. [PDF]
Role of neurotransmitters in multiple pathological processes. Various neurotransmitters, including ACh, EPI, NE, 5‐HT, histamine, DA, glutamate, GABA, and neuropeptides participate in regulating key pathological events, including tumor proliferation, tumor migration, remodeling of the immune microenvironment, and the development of NDDs and ...

Anticonvulsive effect of nonimidazole histamine H3 receptor antagonists
To determine the potential of histamine H3 receptor (H3R) ligands as new antiepileptic drugs (AEDs), aromatic ether, and diether derivatives (1-12) belonging to the nonimidazole class of ligands, with high in-vitro binding affinity at human H3R, were tested for their in-vivo anticonvulsive activity in the maximal electroshock (MES)-induced and ...
