Field of application
RGH-235 is a potent, selective, and orally active H3 receptor antagonist/inverse agonist with high affinity (Ki=3.0-9.2 nM, depending on species), without affinity to H1, H2 or H4 receptors.
JNJ10191584 (VUF6002) is an orally active and selective histamine H4 receptor antagonist with a Ki value of 26 nM. JNJ10191584 shows 540-fold selectivity to H4 receptor over H3 receptor with a Ki value of 14.1 μM. JNJ10191584 inhibits chemotaxis of eosinophils and mast cells with IC50 values of 530 nM and 138 nM, respectively.
Cetirizine methyl ester is an impurity of Cetirizine. Cetirizine, a second-generation antihistamine and the carboxylated metabolite of hydroxyzine, is a specific, orally active and long-acting histamine H1-receptor antagonist.
Cipralisant (GT-2331) enantiomer is the enantiomer of Cipralisant, Cipralisant is an orally active, potent, selective, and high affinity histamine H3 receptor antagonist (rat Ki=0.47 nM).
Tecastemizole (Norastemizole), a major metabolite of Astemizole, is a potent and selective H1 receptor antagonist. Tecastemizole shows anti-inflammatory activities.
Dimaprit dihydrochloride is a selective histamine H2 receptor agonist, it also inhibits nNOS with an IC50 of 49 μM. Dimaprit dihydrochloride can stimulate gastric acid secretion.
Oxatomide is a potent and orally active dual H1-histamine receptor and P2X7 receptor antagonist with antihistamine and anti-allergic activity. Oxatomide almost completely blocks the ATP-induced current in human P2X7 receptors (IC50 of 0.95 μM). Oxatomide inhibits ATP-induced Ca2+ influx with an IC50 value of 0.43 μM and also inhibits serotonin.
Imetit dihydrobromide (VUF 8325 dihydrobromide) is a high affinity and potent agonist of histamine H3 and H4 receptors, with Ki values of 0.3 and 2.7 nM, respectively. Imetit mimics histamine effect in triggering a shape change in eosinophils (EC50=25 nM).
