Raman and NMR spectroscopy together with DFT quantum chemical calculations have been used to elucidate conformational changes occurring during inverse temperature transition in water solution of two elastin-like polypentapeptides, poly(G1V1G2V2P) and poly(AV1GV2P). From the temperature dependences of Raman spectra and1H–1H NOESY spectra follows that above the transition temperature aβ(II)-turn conformational structure is formed on the residue located between Pro and Val1.

“…[16][17][18] Furthermore, CDs have been successfully used in adjusting self-assembling behaviors of amphiphiles. [19][20][21] Although there are some papers about complexation between CDs and a thermosensitive polymer, 22,23 only a few focus on the complexation between CDs and the side groups of a thermosensitive homopolymer. Recently, Schmitz and Ritter 24 synthesized poly(N-(3-(dimethylamino)propyl)-methacrylamide).…”

Effect of Inclusion Complexation with Cyclodextrin on the Cloud Point of Poly(2-(dimethylamino)ethyl methacrylate) Solution

We investigated the influence of addition of cyclodextrin (CD) on the cloud point of poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) aqueous solution. Both beta-CD and randomly methylated beta-cyclodextrin (RM-beta-CD) raised the cloud point of PDMAEMA solution; by contrast, the addition of alpha-CD or gamma-CD did not affect the cloud point of PDMAEMA solution. The inclusion complexation between side group of PDMAEMA and RM-beta-CD was confirmed by NMR experiments. The cloud point of PDMAEMA solution was raised gradually with the increase of concentration of RM-beta-CD. On the basis of inclusion complexation equilibrium, we deduced an equation, which clearly described the relationship between cloud point and concentration of RM-beta-CD. This analysis will provide an important theoretic guide for other related research. In comparison with copolymerization with another monomer, such a supramolecular approach avoids a series of synthesis and facilitates fine-tuning of cloud point.

Short polypeptides with four pentad repeats, (VPGVG)(4) and (VPAVG)(4), were synthesised by manual fluorenylmethoxycarbonyl/tert-butyl (Fmoc/t-Bu) solid phase peptide synthesis using a convergent approach. In the next step, the peptides were coupled via their N-terminus with activated semi-telechelic poly(ethylene glycol) O-(N-Fmoc-2-aminoethyl)-O'-(2-carboxyethyl)undeca(ethylene glycol) (Fmoc-PEG-COOH) to yield monodisperse Fmoc-PEG-peptide diblock copolymer. Both the presence of the terminal hydrophobic Fmoc group and the hydrophilic PEG chain in the copolymers were shown to play a crucial role in their self-associative behaviour, leading to reversible formation of supramolecular thermoresponsive assemblies. The peptides and their PEG derivatives were characterised by HPLC, NMR and MALDI-TOF MS. The associative behaviour of the peptides and their PEG derivatives was studied by dynamic light scattering, MAS NMR and phase contrast microscopy. [image: see text]
