pEC50: 11.46 (human CRF1, CHO cells), 9.36 (human CRF2, CHO cells), 9.85 (rat CRF2α, CHO cells)[1] Ki: 0.4 nM (hCRF1, cell assay), 1.8 nM (rCRF2α, cell assay), and 5.7 nM (mCRF2β, cell assay)[2]
In Vitro Urotensin I is a 41-aa neuropeptide, acts as an agonist of CRF receptor with pEC50s of 11.46, 9.36 and 9.85 for human CRF1, human CRF2 and rat CRF2α receptors in CHO cells[1] and with Kis of 0.4, 1.8, and 5.7 nM for hCRF1, rCRF2α and mCRF2β receptors in cell assay, respectively[2]. Urotensin I exhibits a striking sequence homology with ovine corticotropin-releasing factor and with frog sauvagine, and has potent hypotensive activity and corticotropin-releasing activity[3]. Urotensin I stimulates the release of ACTH from an isolated dispersed goldfish anterior pituitary cell column[4].
