Jagged-1 (188-204) TFA(219127-21-6 free base) is a fragment of the JAG-1 protein. JAG-1 is Notch ligand, a peptide that is the most conspicuously expressed ligand in skin. JAG-1 induces epidermal maturation. Exposing submerged keratinocytes monolayers to JAG-1 with elevated calcium concentration produces stratification with loricrin expression and NF-alphaB activation.

UFP101 is a synthetic peptide that functions as an antagonist of the nociceptin receptor, demonstrating high affinity with a Ki of 0.06 nM in CHO cells expressing the human receptor. It exhibits selectivity for the nociceptin receptor over the κ-opioid receptor, with a Ki of 204 nM in CHO cells expressing the rat receptor. The compound effectively inhibits GTPγS release from the nociceptin receptor in CHO cell membranes, with an EC50 of 1.86 nM.
