backbone length was extended (peptide 9), or the side chain of the residue at position 7 was replaced by an aromatic ring (peptide 6), or the rotation of the amide bond was restricted (peptide 8), the nanostructure changed from fibrils to vesicles. The results also indicate that the increasing hydrophilicity had little influence on the nanostructure morphology. In addition, a suitable release rate was found
antagonists with new substitutions in position 6 or positions 5 and 6 that included lysine acylated at the epsilon-amino group with different heterocyclic carboxylic acids or amino-substituted heterocyclic carboxylic acids was synthesized. These novel analogs wee synthesized on a solid-phase support via the acylation of lysine residue in otherwise protected resin-bound peptides. All analogs were tested

Insulin derivatives having a built-in glucose sensor, capable of delivering insulin from a depot as a function of the glucose concentration in the surrounding medium (e.g. tissue), such that the rate of insulin release from the depot increases with an increased glucose concentration and decreases with a decreased glucose concentration.
