The well plate was then placed back into the incubator to allow the cells to acclimate with the sample and kept undisturbed for 36 h. For the fragment condensation, a solution of 7 0. Although a similar number and morphologies of live cells are noted in A and C , more dead cells are noted in the collagen coated controls C compared with the surface coated with peptide 1 A. However, on the surface coated with the irradiated peptide B , the fibroblasts do not show spindle shaped morphology, and most of the cells are dead. With the limited cytotoxicity data at hand, the cytotoxic effect observed cannot be ascribed to a particular compound.

The cytotoxicity of the pu compounds is not known. At each temperature, the sample was equilibrated for 4 min prior measurement of the spectrum.

The photoreactive peptide 1 was synthesized from hexapeptide 8which was elongated by repeated coupling of pre-prepared peptide 7 by on resin fragment condensation.

J Am Chem Soc. Furthermore, peptide 1 promotes cell adhesion and migration. The videeo was monitored by TLC until near completion 24 h. Han D, Gouma PI. Column chromatography was performed on silica gel 60, — mesh from Natland International Corp. Fluorescence spectra were measured on a Shimadzu RF spectrofluorophotometer using standard quartz cuvettes of 1 cm path length at rt.

Conclusions A photoreactive 34mer collagen-like peptide 1 with four photoreactive N -peptidylnitroindoline moieties included was synthesized, and its photochemical and photophysical properties were studied.

Experimental Reagents and solvents Fmoc amino acid derivatives were purchased from Anaspec Inc. Diphenyldiazomethane resin loading capacity 0. Author information Copyright and License information Disclaimer. Shown are representative merged images captured using bright field and fluorescence, where the green fluorescence depicts k cells and the red fluorescence indicates dead cells.

The photoreactive building block 6 0. Angew Chem, Int Ed. Upon excitation, the photoreactive peptide 1 emits a weak fluorescence, which decreases over time. Its circular dichroism supports a stable triple helix structure. These data suggest that biomimetic collagen-like photoreactive peptides could potentially be used for growing cells in 2D micropatterns based on patterns generated by photolysis prior to cell growth.

Two-dimensional images in the x — y plane are acquired through a home-built software program. Qualitative cytocompatibility studies suggest that peptide 1 is not toxic to cells, as human mesenchymal stem cells were able to grow on a surface coated with that peptide, and mouse embryonic fibroblasts remained viable.

Illumination of a thin film of the peptide, or a thin film of a photoreactive amino acid vodeo compound containing a 5-bromonitroindoline moiety, with femtosecond laser light at nm allows for the creation of well-resolved micropatterns. Next, the excess fluid was removed from the coated surface and allowed to dry overnight.

The built-in photochemical function enables the vieeo of the peptide into small peptide fragments by illumination with UV light of nm in aqueous solution. The size of the fibrils, the density of the mesh, and the mechanical properties can be controlled by varying the pH, temperature, and oive strength at which the hydrogel is prepared.

A minimum fluorescence threshold was approximated for each image stack, and the fluorescence intensity normalized accordingly. The location of each irradiated spot was recorded before a new spot was irradiated with a new laser excitation power.

However, the cells that did attach retained their viability and morphology implying that peptide 1 created a non-cytotoxic surface A. Several spots within the sample were chosen j irradiation with the femtosecond laser at nm, and each spot was irradiated with a specific excitation laser power mW, mW, mW, mW, or mW. Most Watched April 21, Washington Journal: In general, depending on the water content of the peptide sample at the time of irradiation, several peptidylnitroindolines and peptidylnitrosoindoles are possible photolysis products with potential effects on cell viability.

For the generation of patterns a photomask of the desired pattern was placed at the intermediate image plane in the optical path, and the pattern was projected onto the objective lens focal plane to partially block the illumination light.

Since the attachment of the first amino acid to diphenyldiazomethane resin does not rely on activation with a coupling reagent, this resin is highly suitable for the recovery of unreacted amino acid excess, particularly when it is a precious building block such as the photoreactive glycine derivative 6.

The one-photon absorption properties and release of carboxylic acids caged as N -acylated 7-nitroindolines have been reported in the literature.
