Current Protocols in Pharmacology, 2001
AbstractThis unit describes three standard in vitro bioassays for studying histamine H1, H2 and H3 receptors in isolated intact tissues removed from the guinea pig. Both the H1 and H3 receptor assays are based on preparations of the ileum, whereas the spontaneously beating right atrium assay is used for the H2‐receptor.This unit describes three ...

Histamine H3 Receptor Agonists
Mini-Reviews in Medicinal Chemistry, 2004The SAR of H3 ligands has been difficult to evaluate because of species differences, multiple isoforms and constitutive activity, among other complicating factors. A review is given of the sometimes-conflicting affinity, activity and efficacy data of H3 agonists that has been described in literature to date.

Histamine H4 receptor agonists
Bioorganic & Medicinal Chemistry Letters, 2010Since its discovery 10 years ago the histamine H(4) receptor (H(4)R) has attracted attention as a potential drug target, for instance, for the treatment of inflammatory and allergic diseases. Potent and selective ligands including agonists are required as pharmacological tools to study the role of the H(4)R in vitro and in vivo.

Abstract Histamine [2-(4-imidazolyl)ethylamine, HA] is an endogenous biogenic amine synthesized in and released from several kinds of cells, and involved in many kinds of biological signalling (Uvnas 1991). Mast cells (a family of bone marrow-derived secretory cells) store much of the body’s HA in very high concentrations.

Histamine and Histamine Receptor Antagonists in Cancer Biology
Inflammation & Allergy - Drug Targets, 2010Histamine has been demonstrated to be involved in cell proliferation, embryonic development, and tumour growth. These various biological effects are mediated through the activation of specific histamine receptors (H1, H2, H3, and H4) that differ in their tissue expression patterns and functions.

Histamine H3-receptor isoforms
Inflammation Research, 2004Increasing evidence supports a role for HA as a neurotransmitter and neuromodulator in various brain functions, including emotion, cognition, and feeding. The recent cloning of the histamine H3 receptor allowed for the subsequent cloning of a variety of H3 receptor isoforms from different species as well as the H4 receptor.

Histamine H2-receptor antagonists
Baillière's Clinical Gastroenterology, 1988The first histamine H2-receptor antagonists were developed in the early 1970s, and they have a dominant role in today's management of peptic ulceration. The original regimens using either cimetidine or ranitidine attempted to control acidity across the 24 hours, but more 'modern' regimens use a large single dose of the H2-blocker in the evening, which ...

Histamine and Histamine Receptors in Allergic Dermatitis
2016In this chapter we will first introduce the pathophysiological process of several skin diseases including allergic dermatitis, a common skin disease, including chronic allergic contact dermatitis (CACD), and atopic dermatitis (AD). In CACD and AD patients, repeated skin exposure to antigens contributes to the development of chronic eczematous lesions ...

Histamine H2-Receptor Antagonists
Nursing Clinics of North America, 1991In summary, histamine initiates acid secretion by stimulating the H2 subtype histamine receptor on parietal cells. Cimetidine, rantidine, famotidine, and nizantidine are histamine H2-receptor antagonists that block this action of histamine, reducing gastric acid output and concentration under both basal and stimulated conditions.
