alpha-Helix nucleation constant in copolypeptides of alanine and ornithine or lysine

The alpha-helix is one of a small number of fundamental structural motifs of the peptide backbone that are abundant in native proteins. The forces responsible for its stability have attracted a great deal of theoretical and experimental attention. Helix formation can naturally be considered in terms of two processes, initial nucleation of a helix from a sequence of disordered residues and propagation or growth of helical structure from such a nucleus. Data from a variety of short peptide and polypeptide models have revealed more details about the propagation of helix structure than about helix nucleation. To investigate helix nucleation, we have synthesized two series of high molecular weight polypeptides containing differing ratios of alanine and one of the basic side chains, ornithine or lysine; poly L-alanine is insoluble in water. The CD signals of these copolymers have been analyzed by a program that evaluates the helix content in terms of the experimental chain-length distribution and composition, with the helix nucleation constant (sigma value) and the propagation constants (s values) for the amino acids involved. Fitting the CD data allows the determination of the propagation constants for Orn (s = 0.45) and Lys (s = 0.8) in addition to that of the helix nucleation constant once the s value for Ala is specified. The value of sigma is sensitive to the dependence of the CD signal on helix length; using the Yang equation, [theta]222 = -41000(n – x)/n, with x = 2.5, the nucleation constant value is sigma = 0.004 ± 0.002 at 4 C in the presence of 1 M salt. This value is consistent with earlier estimates based on analysis of the helix-coil transition in poly(Lys), poly(Glu), and shorter Ala-rich peptides. However, if x is taken to be zero, the resulting sigma value is 0.02, considerably larger than the above estimates.

Terpolymerization kinetics of amino acid N-carboxy anhydrides

Based on their versatility with respect to amino acid type and sequence, polypeptides have become attractive for a number of biological applications such as drug delivery, biomineralization, and drugs. N-carboxy anhydride (NCA) polymerization is a convenient way to rapidly prepare high-molecular weight polypeptides with good control over molecular weight and polydispersity. However, the kinetics of the incorporation of NCA monomers into copolypeptides during random copolymerization are poorly understood. Here, kinetic data is presented that allows insight into the NCA polymerization of a terpolymer composed of three commercially relevant amino acids, namely, glutamic acid, lysine, and tyrosine. Furthermore, kinetic data and copolymerization parameters from the copolymerization of binary mixtures of these three amino acid NCAs is used to make predictions of the terpolymer composition. This study provides access to the information necessary to prepare functional copolypeptides with better-defined sequence architecture that will be essential for the future development of polypeptide-based materials.

Microstructure characterization and thermal analysis of hybrid block copolymer alpha-methoxy-poly(ethylene glycol)-block-poly[-(benzyloxycarbonyl)- l-lysine] for biomedical applications

Hybrid block copolymers, which combine the economy and processibility of synthetic polymers with the functionality and highly ordered structures of polypeptides, can enhance control over structure formation at the nanoscale, as well as afford interesting materials that interface with Nature for a diversity of biomedical applications, such as drug delivery, tissue engineering and bioimaging. Hybrid block copolymer, alpha-methoxy-poly(ethylene glycol)-b-poly[epsilon-(benzyloxycarbonyl)-l-lysine], MPEG-b-PLL(Z), was synthesized by anionic ring-opening polymerization in excellent yield, and fully characterized using IR, 1H, 13C and 2-D NMR, GPC, TGA, DTGA, DSC, MDSC and polarimetry. Its precursor NCA, epsilon-(benzyloxycarbonyl)- l-lysine N-carboxyanhydride, l-Lys(Z)-NCA, was prepared in 97% yield; and a double doublet observed in the 1850-1750 cm-1 absorption region of its infrared spectrum, for the characteristic NCA carbonyl absorption bands, is discussed.

Biodegradable Poly(ethylene glycol)-co-poly(l-lysine)-g-histidine Multiblock Copolymers for Nonviral Gene Delivery

The development of biodegradable cationic polymers for use in nonviral gene delivery was discussed. This high molecular weight multiblock copolymer (MBC) consists of repeating units of low molecular weight poly(ethylene glycol) conjugated to low molecular weight cationic(L-lysine). These MBC protected pDNA from endonuclease digestion for at least two hours. The pK of the conjugated imidazoles was found to be 4.75 which would facilitate buffering at low pH environments of the late endosome/lysosome.

Synchrotron small-angle X-ray scattering study of cross-linked polymeric micelles

Polymeric micelles of methoxypoly(ethylene glycol)-b-poly(lactide) containing lysine units (mPEG- PLA-Lys4) were cross-linked by reacting of lysine moieties with a bifunctional bis(N-hydroxysuccinimide ester). The micelles were characterized in aqueous solution using dynamic light scattering, transmission electron microscopy, and synchrotron small-angle X-ray scattering. The mPEG-PLA-Lys4 was synthesized through the ring-opening polymerization of N6-carbobenzyloxy- L-lysine N-carboxyanhydride with amine-terminated mPEG-PLA and subsequent deprotection. The polymeric micelles showed enhanced micelle stability after cross-linking, which was confirmed by adding sodium dodecyl sulfate as a destabilizing agent. The average diameters measured via dynamic light scattering were Delivered 19.1 nm by Ingenta and 29.2 nm for non-cross-linked polymeric micelles (NCPMs) and cross-linked polymeric micelles (CPMs), respectively. The transmission electron microscopy images showed that the size of the polymeric micelles increased slightly due to crosslinking, which was in good agreement with the DLS measurements. The overall structures and internal structural changes of NCPMs and CPMs in aqueous solution were studied in detail using synchrotron X-ray scattering method. According to the structural parameters of X-ray scattering analysis, CPMs with a more densely packed core structure were formed by reacting bifunctional cross-linking agents with lysine amino groups located in the innermost core of the polymeric micelles.

Multifunctional biocompatible and biodegradable folic acid conjugated poly(epsilon-caprolactone)-polypeptide copolymer vesicles with excellent antibacterial activities

Cancer patients after chemotherapy may also suffer bacterial attack due to badly decreased immunity. Although with high bacterial efficacy, conventional antibiotics are prone to inducement of drug resistance and may be not suitable for some cancer patients. In contrast, antibacterial peptides are highly effective in inhibiting bacteria without inducing resistance in pathogens. Presented in this article is a novel kind of highly effective antibacterial peptide-based biocompatible and biodegradable block copolymer vesicle. The copolymer is poly(epsilon-caprolactone)-block-poly[phenylalanine-stat-lysine-stat-(lysine-folic acid)] [PCL19-b-poly[Phe12-stat-Lys9-stat-(Lys-FA)6]], which can self-assemble into vesicles in aqueous solution. The biocompatible and biodegradable PCL forms the vesicle membrane, whereas the poly[Phe12-stat-Lys9-stat-(Lys-FA)6] block constitutes the vesicle coronas. Compared to the individual polymer chains, the vesicles showed enhanced antibacterial activities against both Gram-positive and Gram-negative bacteria (16 mug mL-1) due to the locally concentrated antibacterial poly[Phe12-stat-Lys9-stat-(Lys-FA)6] coronas, which may avoid the inducement of antibiotic-resistant bacteria and side effects of multidrug interactions. Furthermore, folic acid is introduced into the vesicle coronas for potential further applications such as cancer-targeted drug delivery. Moreover, the amino groups can be further functionalized when necessary. This low cytotoxic, biocompatible, biodegradable, and antibacterial vesicle (without antibiotic resistance) may benefit patients after tumor surgery because it is highly anti-inflammatory, and it is possible to deliver the anticancer drug to tumor cells simultaneously.
