Difelikefalin-d5 hydrochloride
Based on 1 Customer Validation
Difelikefalin-d5 hydrochloride (CR-845-d5 hydrochloride; FE-202845-d5 hydrochloride) is the deuterated-labeled Difelikefalin (HY-17609). Difelikefalin (CR-845; FE-202845) is an orally active peripherally acting kappa opioid receptor agonist. Difelikefalin reduces acute kidney injury, decreases oliguria, maintains urine flow, inhibits cytokine expression, and improves survival in endotoxemia after ischemia/reperfusion. Difelikefalin suppresses pruritus signals and exhibits neuromodulatory antipruritic activity. Difelikefalin can be used in research related to acute kidney injury, chronic kidney disease-associated pruritus, and atopic dermatitis.
