TECHNICAL RESEARCH NOTES

01

Cyclic heptapeptide analog of α-MSH with enhanced metabolic stability versus linear parent peptide

02

Selective agonist activity at MC3R and MC4R; MC4R activation implicated in CNS-mediated pathways

03

Resistant to enzymatic degradation due to cyclic backbone and D-Phe substitution at position 4

04

Avoid prolonged exposure to light; lyophilized form is photosensitive — store in amber vials
