Background:

Urocortin, rat is a selective agonist of CRF receptor, with Kis of 0.32, 2.2, and 0.62 nM for hCRF1, rCRF2α and mCRF2β, respectively.

Urocortin, rat is a selective agonist of CRF receptor, with Kis of 0.32, 2.2, and 0.62 nM for human CRF1, rat CRF2α and mouse CRF2β, respectively[1].

Urocortin (0.01 to 10 μg) decreases food intake in both food-deprived and non-deprived rats and such a effect also observed in mice after 1 μg of Urocortin i.c.v. administration. Urocortin has the potential of inducing anxiogenic behavior[2].
