Peptidic hydrogels are an interesting class of materials, with potential applications in tissue engineering and controlled drug delivery. Fmoc–Phe3 self-assembling peptide was synthesized in an aqueous phase by using a lipase from Pseudomonas fluorescens. The bioconversion afforded a self-supporting hydrogel in only 10 minutes, a feature that seems very promising for biotechnological applications. The rheological properties of such material were studied. The peptide hydrogel, used as a scaffold for culturing rat microglial cells, induced a significant cell proliferation and an increased production of the neurotrophic factor NGF. Moreover, microscopy studies demonstrated that the hydrogel was able to promote microglial cell adhesion.

with a range of unprotected side chains of aminoacid. The ability to produce amide or peptides by a traceless removal of the auxiliary is a significant virtue of the method. Meanwhile, the application of this new peptide-bond-forming reaction to the synthesis of novel endomorphin (EM) derivatives with various binding potencies was realized.

[reaction: see text] Solid-phase Staudinger ligation of small peptides was performed on a novel core-shell-type resin. Solid-phase Staudinger ligation was mediated by synthetic solid-supported phosphinothiol, which was readily prepared by a straightforward synthetic route. This protocol afforded final peptide products in excellent yields and purities and thus could provide the opportunity to facilitate

PEGA resin (a copolymer of polyethylene glycol and polyacrylamide). Here we explore the scope of this methodology for using protected and glycosylated amino acids as well as the synthesis of longer peptides on resin and show that such a method can also be applied on non-porous surfaces, in particular on gold.

Solubleoligomericstyrenesupports are reported here with high loading capacities of 1.5–1.6 mmol/g similar to resins used in solid phase peptidesynthesis. Oligoether and alkyl chains are incorporated into the scaffold to improve the supportsolubility and act as spacers between the attachment sites. Amino acids have been attached to the support in 59–85% yields and 0.87–1.3 mmol/g loading. The supports
