These polypeptide block copolymers have attracted particular attention because of their tendency to form liquid crystals and because they can be selectively degraded by enzymolysis. [Pg.187]

Recently, polypeptide hybrid polymers, particularly poly(ethylene glycol) (PEG)-polypeptide block copolymers, have been attracting significant interest for polymer therapeutics, such as drug and gene dehvery systems [1-5]. [Pg.114]

Linear polypeptide block copolymers, block copolymers with pendent sugar or peptide grafts, and modified linear or dendritic homopolymers have been used to produce vesicles based on hydrophobic interactions and packing issues. Usually, the peptides or sugars make the minority hydrophilic part of the copolymers and are thus incorporated in the corona and not in the membrane of the vesicles. For the inverse case, the hydrophobic peptides in the membrane are often too short to adopt a stable secondary structure. [Pg.170]

Kataoka et al. [57, 58] investigated the formation of polyion complexes (PIC) from a pair of oppositely charged polypeptide block copolymers, namely of anionic poly(ethylene oxide)-( foc -poly(a, P-aspartate) and cationic polyethylene oxide)- foc -poly([2-aminoalkyl]-a,P-aspartamide) (see structure in Fig. 14a), in an aqueous milieu. Mixing of the double-hydrophilic copolymers at an equimolar... [Pg.184]

The lattice model, as put forth by Flory [84, 85], has been proved successful in the treatments of the liquid crystallinity in polymeric systems, despite its artificiality. In our series of work, the lattice model has been extended to the treatment of biopolypeptide systems. The relationship between the polypeptide ordering nature and the LC phase structure is well established. Recently, by taking advantage of the lattice model, we formulated a lattice theory of polypeptide-based diblock copolymer in solution [86]. The polypeptide-based diblock copolymer exhibits lyotropic phases with lamellar, cylindrical, and spherical structures when the copolymer concentration is above a critical value. The tendency of the rodlike block (polypeptide block) to form orientational order plays an important role in the formation of lyotropic phases. This theory is applicable for examining the ordering nature of polypeptide blocks in polypeptide block copolymer solutions. More work on polypeptide ordering and microstructure based on the Flory lattice model is expected. [Pg.171]

The fiber-like structure of polypeptide block copolymers is essential in organogels that are formed by the side-by-side packing of polypeptide rods. Similarly, such side-by-side packing of polypeptide rods can also be found in cylindrical micelles self-assembled from polypeptide block copolymers. In both the fiber-like gels and cylindrical micelles, polypeptide rods assemble into ordered structures, while the flexible chains are spread out into the surroundings to stabilize the structures. [Pg.181]
