Urocortin II (mouse) trifluoroacetate salt

Urocortin II, mouse is a potent and selective endogenous peptide agonist of type-2 corticotropin-releasing factor (CRF2) receptor with Ki values of 0.66 nM and ﹥100 nM for CRFR2 and CRFR1, respectively. Urocortin II, mouse activates CRF2 receptors in a cAMP/PKA- and Ca2+/CaMKII-dependent manner.Urocortin II, mouse is expressed in discrete areas of the central nervous system, and activates central neurons involved in the processing of visceral sensory information, and in modulating autonomic outflow[1][2][3].

Urocortin II, mouse (1-10 μg; icv and i.v.; 成年雄性 SD 大鼠) 诱导 Fos 的表达[2]。 Urocortin II, mouse (1 μg; icv; 成年雄性 SD 大鼠) 参与中枢自主神经系统和食欲控制[2]。 Animal Model: Adult male Sprague-Dawley rats (250-300 g)[2] Dosage: 1, 5, and 10 μg Administration: Intracerebroventrical injection and intravenous injection; 1, 5, or 10 μg per animal in 2 μL of saline for i.c.v. injections or 200 μL for i.v. administration Result: Induced Fos expression in a dose-dependent manner. Animal Model: Adult male Sprague-Dawley rats (250-300 g)[2] Dosage: 1 μg Administration: Intracerebroventrical injection Result: Reduced food intake over the 12-h interval.
