LRGILS-NH2 is a reversed amino acid sequence control peptide for SLIGRL-NH2, a protease-activated receptor-2 (PAR2) agonist that facilitates gastrointestinal transit in vivo.
Potent agonist of the nociceptin (ORL1) receptor, demonstrated both in vitro and in vivo. Selective, competitive antagonism at the nociceptin receptor has also been reported (pA2 = 7.02 and 6.75 in the guinea pig ileum and mouse vas deferens respectively)
