Biochem/physiol Actions
Ramatroban aids in the reduction of myocardial ischemia-reperfusion injury, lipopolysaccharide-induced shock, and vagal neuroeffector transmission in the tracheal smooth muscle of experimental models. In addition, it also suppresses allergen and IgE antibody-mediated skin and nasal reactions and eosinophilia in animal models with asthma.
Ramatroban is used for the treatment of allergic rhinitis as an antagonist of the thromboxane receptor.
Ramatroban is used for the treatment of allergic rhinitis as an antagonist of the thromboxane receptor. It is also an antagonist of the DP2 receptor with IC50 values of 100-170 nM. It is more potent at the DP2 receptor than the TP receptor by 4-5 fold. It is therefore a useful tool for the elucidation of PGD2/DP2 function in eosinophils, basophils, and other cells of the TH2 cell-type.

A chemoenzymatic asymmetric route for the preparation of enantiopure (R)-ramatroban has been developed for the first time. The action of lipases and oxidoreductases has been independently studied, and both were found as excellent biocatalysts for the production of adequate chiral

The pathogenesis of eosinophilic otitis media is not yet fully understood. The purpose of this paper is to describe the clinical course of our two patients with eosinophilic otitis media and to discuss the pathogenesis and treatment of this intractable

Chemoattractant receptor homologous molecule of Th2 cells (CRTH2) has been shown to mediate the chemotaxis of eosinophils, basophils and Th2-type T lymphocytes. The major mast cell product prostaglandin (PG) D(2) is considered to be the principal ligand of CRTH2. We

PGD(2) is the major prostanoid produced during the acute phase of allergic reactions. Two PGD(2) receptors have been isolated, DP and CRTH2 (chemoattractant receptor-homologous molecule expressed on Th2 cells), but whether they participate in the pathophysiology of allergic diseases remains
Update on the development of antagonists of chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2). From lead optimization to clinical proof-of-concept in asthma and allergic rhinitis.
