(Leu31,Pro34)-Peptide YY (human) is a Peptide YY (HY-P1514) derivative and is a potent and selective Y1 agonist with a KD of 1.0 nM[1]. | [in vivo]
(Leu31,Pro34)-Peptide YY (0.1-1 nmol/day; ICV; 14 days) displays anxiolytic and antidepressant effect in rats[2]. | Animal Model: | Male Sprague Dawley rats weighing 150-170 g, OBX/Sham model[2] | | Dosage: | 0.1, 0.3 and 1 nmol/day | | Administration: | ICV, for 14 days | | Result: | Significantly decreased hyperlocomotion and immobility time in OBX animals. Reversed the deficit in social contacts in OBX animals. Reduced grooming behavior in sham animals.
