Chemical structure of Melanotropin-Potentiating Factor

GA23188

Melanotropin-Potentiating Factor

Also known as (2S)-2-[[2-[[(2S)-6-amino-2-[[(2S)-2,6-diaminohexanoyl]amino]hexanoyl]amino]acetyl]amino]pentanedioic acid

KKGE, the C-terminal tetrapeptide of β-endorphin, potentiates the interaction of β-endorphin with its brain opiate receptors· KKGE also potentiates the melanotropic activity of melanocyte-stimulating hormones (MSH) and seems to be involved in other biological systems
