GA23193

Metamorphosin A

Also known as (2S)-N-[(2S)-5-amino-1-[(2S)-2-[[2-[[(2S)-1-[[(2S)-1-amino-3-(1H-indol-3-yl)-1-oxopropan-2-yl]amino]-4-methyl-1-oxopentan-2-yl]amino]-2-oxoethyl]carbamoyl]pyrrolidin-1-yl]-1,5-dioxopentan-2-yl]-5-oxopyrrolidine-2-carboxamide

Antho-LWamide II, originally isolated from the anthozoan Anthopleura elegantissima, triggers metamorphosis in Hydractinia echinata· Histochemical studies have shown that MMA is a neuropeptide
