(D-Ala²,N-Me-Phe⁴,methionin(O)-ol⁵)-Enkephalin

Also known as (2S)-2-amino-N-[(2R)-1-[[2-[[(2S)-1-[[(2S)-1-hydroxy-4-methylsulfinylbutan-2-yl]amino]-1-oxo-3-phenylpropan-2-yl]-methylamino]-2-oxoethyl]amino]-1-oxopropan-2-yl]-3-(4-hydroxyphenyl)propanamide

DAMME (FK 33-824) shows only slight preference for µ-receptors over δ-receptors and has no significant affinity for K-receptors· DAMME exerts a potent analgesic effect after systemic administration· It is one of the best-known analogs that has undergone fairly extensive clinical testing
