Three new cyclohexadepsipeptides, arenamides A−C (1−3), were isolated from the fermentation broth of a marine bacterial strain identified as Salinispora arenicola. The planar structures of these ...

The coordination of transition metal ions to PrP (61−84) induces the significant geometrical changes in the PrP (61−68) and Prp (69−76) octapeptide repeat regions.
