Urocortin II, human 

Urocortin II, human is a selective endogenous peptide agonist of type-2 corticotropin-releasing factor (CRF2) receptor. Urocortin II, human has an effect of promoting satiet and neuroprotective effect. Urocortin II, human also has bactericidal, antiparasitic and pro-inflammation activity. Urocortin II, human can activate NF-κB pathway and ERK1/2 MAP kinase. Urocortin II, human can reduce pulmonary arterial hypertension and shows cardiac protection effect. Urocortin II, human can be used for the researches of infection, inflammation, metabolic, neurological and cardiovascular disease^{[1][2][3][4][5]}.

Urocortin II, human shows bactericidal activity against E. coli, P. pseudoalcaligenes and M. luteus with EC₅₀ values of 2.81, 1.16 and 4.92 μM^[3].
Urocortin II, human shows antiparasitic activity against L. major, L. tropica and L. infantum with EC₅₀ values of 9.20, 22.41 and 12.47 μM^[3].
Urocortin II, human (0.1-1000 nM, 6-24 h) induces IL-8 mRNA and protein expression, activates the NF-κB pathway (IkBα degradation, p65 phosphorylation) and ERK1/2 MAP kinase in human colonic epithelial NCM460 cells overexpressing CRHR2α^[5].

Urocortin II, human (0.1-10 μg/mouse; i.c.v.; 30 minutes before the start of the dark) reduces the intake of foods and water and inhibit delayed movement in Wistar rats^[1].
Urocortin II, human (2.5 μg/kg; i.p.; single dose) shows neuroprotective effect in intracerebral hemorrhage of rats^[2].
Urocortin II, human (1 nM/mouse, i.p., administered at 1, 12, and 24 h after cecal ligation and puncture) improves survival rate, reduces bacterial load and inflammatory mediator levels in blood and peritoneal fluid, and alleviates tissue pathological damage in female BALB/c mouse models of sepsis^[3].
Urocortin II, human (5 μg/kg, i.p., twice a day for 10 days) reduces pulmonary arterial hypertension, improves exercise capacity and attenuates pulmonary arterial and right ventricular remodelling and dysfunction in Monocrotaline (HY-0750)-induced rats^[4].
