[Conformation states of thymopentin and its synthetic analogs]

Spatial structures of the biologically active fragment Arg-Lys-Asp-Val-Tyr of tymopoetin (tymopentin) and its synthetic analogs: [Lys1-Arg2]-, [Glu3]- and [Gly3] have been investigated by theoretical conformational analysis. These results indicate that the conformational properties of fragments are represented in aqueous solution by five different backbone forms.
