Imetit dihydrobromide
S-[2-(Imidazol-4-yl)ethyl]isothiourea dihydrobromide

Biological Activity

[Description]:

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)[1][2][3].

[Target]

H3 Receptor:0.3 nM (Ki)

H4 receptor:2.7 nM (Ki)

[In Vivo]

Imetit dihydrobromide (2.5-10 mg/kg; i.p.) reduces the licking response induced by Apomorphine[4]. Animal Model: Male Sprague-Dawley rats[4] Dosage: 2.5, 5, 10 mg/kg Administration: i.p. (30 min before Apomorphine) Result: Reduced the licking response induced by Apomorphine.
