Notes: [Ala11,D-Leu15]-Orexin B is a synthetic peptide agonist of the orexin 2 (OX2) receptor.{68451} It selectively induces calcium mobilization in CHO-K1 cells expressing OX2 over CHO-K1 cells expressing OX1 (EC50s = 0.13 and 52 nM, respectively, for the human receptors). [Ala11,D-Leu15]-Orexin B inhibits forskolin-, PACAP (1-27)-, or VIP-induced cAMP formation in primary rat neuronal cells (IC50s = 42, 32.3, and 22.9 nM, respectively).{28459} It increases mean arterial pressure (MAP), heart rate, and phrenic nerve activity in rats when intracranially administered at a dose of 0.75 pmol/animal.{68452}
