High potency and broad-spectrum antimicrobial peptides synthesized via ring-opening polymerization of alpha-Aminoacid-N-carboxyanhydrides

Antimicrobial peptides (AMPs), particularly those effective against methicillin-resistant Staphylococcus aureus (S. aureus) and antibiotic-resistant Pseudomonas aeruginosa (P. aeruginosa), are important alternatives to antibiotics. Typical peptide synthesis methods involving solid-phase sequential synthesis are slow and costly, which are obstacles to their more widespread application. In this paper, we synthesize peptides via ring-opening polymerization of alpha-amino acid N-carboxyanhydrides (NCA) using a transition metal initiator. This method offers high potential for inexpensive synthesis of substantial quantities of AMPs. Lysine (K) was chosen as the hydrophilic amino acid and alanine (A), phenylalanine (F), and leucine (L) as the hydrophobic amino acids. We synthesized five series of AMPs (i.e., P(KA), P(KL), P(KF), P(KAL), and P(KFL)), varied the hydrophobic amino acid content from 0 to 100%, and determined minimal inhibitory concentrations (MICs) against clinically important Gramnegative and Gram-positive bacteria and fungi (i.e., Escherichia coli (E. coli), P. aeruginosa, Serratia marcescens (S. marcescens), and Candida albicans (C. albicans). We found that P(K10F 7.5L7.5) and P(K10F15) show the broadest activity against all five pathogens and have the lowest MICs against these pathogens. For P(K10F7.5L7.5), the MICs against E. coli, P. aeruginosa, S. marcescens, S. aureus, and C. albicans are 31 mug/mL, 31 mug/mL, 250 mug/mL, 31 mug/mL, and 62.5 mug/mL, while for P(K10F15) the respective MICs are 31 mug/mL, 31 mug/mL, 250 mug/mL, 31 mug/mL, and 125 mug/mL. These are lower than the MICs of many naturally occurring AMPs. The membrane depolarization and SEM assays confirm that the mechanism of microbe killing by P(K10F 7.5L7.5) copeptide includes membrane disruption, which is likely to inhibit rapid induction of AMP-resistance in pathogens.

Dual-pH sensitive charge-reversal polypeptide micelles for tumor-triggered targeting uptake and nuclear drug delivery

A novel dual-pH sensitive charge-reversal strategy is designed to deliver antitumor drugs targeting to tumor cells and to further promote the nuclei internalization by a stepwise response to the mildly acidic extracellular pH (?6.5) of a tumor and endo/lysosome pH (?5.0). Poly(l-lysine)-block-poly(l-leucine) diblock copolymer is synthesized and the lysine amino residues are amidated by 2,3-dimethylmaleic anhydride to form beta-carboxylic amide, making the polypeptides self-assemble into negatively charged micelles. The amide can be hydrolyzed when exposed to the mildly acidic tumor extracellular environment, which makes the micelles switch to positively charged and they are then readily internalized by tumor cells. A nuclear targeting Tat peptide is further conjugated to the polypeptide via a click reaction. The Tat is amidated by succinyl chloride to mask its positive charge and cell-penetrating function and thus to inhibit nonspecific cellular uptake. After the nanoparticles are internalized into the more acidic intracellular endo/lysosomes, the Tat succinyl amide is hydrolyzed to reactivate the Tat nuclear targeting function, promoting nanoparticle delivery into cell nuclei. This polypeptide nanocarrier facilitates tumor targeting and nuclear delivery simultaneously by simply modifying the lysine amino residues of polylysine and Tat into two different pH-sensitive beta-carboxylic amides.

Determination of enantiomeric purity of commercial 14C- and 3H- labeled L-alpha-amino acids

The enantiomeric purity of twelve commercial 14C- and 3H-labeled L- alpha-amino acids was determined using reverse isotope dilution analysis. The technique utilized reversed-phase (RP) thin-layer chromatography (TLC) and beta-cyclodextrin (beta-CD) in the mobile phase to separate D- and L-amino acids as their 5-dimethylamino-1-naphthalene sulfonyl (dansyl, DNS) derivatives. In all cases, the L-amino acid was contaminated with the D- isomer. This is the first report of the resolution of N-DNS-DL-tyrosine and N-(alpha)-DNS-DL-lysine using this methodology.

Stack exchange strategies for the synthesis of covalent double-channel photosystems by self-organizing surface-initiated polymerization

Ring-opening disulfide exchange polymerization has recently been identified as ideal for synthesizing single-channel photosystems by self-organizing surface-initiated polymerization (SOSIP). Here we introduce chemoorthogonal hydrazone exchange chemistry to engineer additional channels into single-channel photosystems. Post-SOSIP stack exchange is shown to provide facile access to complete supramolecular n/p-heterojunction architectures with high activity and freely variable composition, including oriented antiparallel redox gradients. With appropriate templation from the surface, post-SOSIP stack exchange is nearly quantitative.

Enzyme-purification and catalytic transformations in a microstructured PASSflow reactor using a new tyrosine-based Ni-NTA linker system attached to a polyvinylpyrrolidinone-based matrix

The synthesis of a Ni-nitrilotriacetic acid (Ni-NTA) attached via a new tyrosine-based linker matrix on monolithic crosslinked poly(vinyl benzyl chloride)/poly(vinylpyrrolidinone) is described. This matrix is incorporated inside a microstructured PASSflow reactor which was used for automatic purification and immobilisation of His6-tagged proteins. These could be used as stable and highly active biocatalysts for the synthesis of (R)-benzoin (6), (R)-2-hydroxy-1-phenylpropan-1-one (7) and 6-O-acetyl-d-glucal (17) in a flow-through mode.
