Conformational Study of Structurally Constrained 18-Membered Cyclic Peptide-Containing N,N’-Ethylene-Bridged-(S)-Phenylalanyl-(S)-Phenylalanine
The conformation of cyclo[(2S,3’S)-2-(3’-benzyi-2’-oxopiperazin-1’-yl)-3 -phenyl-propanoyl-glycyl](2) crystallized with two water molecules (C44H46N6O6 . 2H(2)O) is compared with its solution structure and those of cyclo[(2S,3’S)-2-(3’-methyl-2’-oxopiperazin-1’-yl)-propanoyl- glycyl](2).
