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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: oxazolidine, you can also check out more blogs about1676-86-4

Poly(l-lysine) modified zein nanofibrous membranes as efficient scaffold for adhesion, proliferation, and differentiation of neural stem cells

Excellent biocompatibility and bioactivity are necessary requirements for a scaffold for nerve repair and regeneration. Natural plant protein zein was chosen as the primary material and poly(l-lysine), which is composed of common amino acids in the human body, was used to modify it. Poly(l-lysine) modified zein (ZPLL) with different PLL contents of 1.46%, 3.57%, and 6.18% was synthesized and nanofibrous membranes were prepared by electrospinning. The hydrophilicity of the membranes improved with an increase of PLL content. The biodegradability of the membranes was proved by in vitro experiments. Compared with pure zein membranes, ZPLL membranes can efficiently improve cell viability, adhesion, proliferation, and differentiation of neural stem cells (NSCs) and the effect of PLL content was further investigated. The results show that when the PLL content was 3.57%, cell adhesion and proliferation proved to be the best and most differentiated toward mature neurons with extensive neurite formation and astrocytes rather than oligodendrocytes. The ZPLL was made into nerve conduits for future study and they may be a promising biomaterial for nerve repair and regeneration.

Biocatalysis as useful tool in asymmetric synthesis: An assessment of recently granted patents(2014-2019)

The broad interdisciplinary nature of biocatalysis fosters innovation, as different technical fields are interconnected and synergized. A way to depict that innovation is by conducting a survey on patent activities. This paper analyses the intellectual property activities of the last five years (2014-2019) with a specific focus on biocatalysis applied to asymmetric synthesis. Furthermore, to reflect the inventive and innovative steps, only patents that were granted during that period are considered. Patent searches using several keywords (e.g., enzyme names) have been conducted by using several patent engine servers (e.g., Espacenet, SciFinder, Google Patents), with focus on granted patents during the period 2014-2019. Around 200 granted patents have been identified, covering all enzyme types. The inventive pattern focuses on the protection of novel protein sequences, as well as on new substrates. In some other cases, combined processes, multi-step enzymatic reactions, as well as process conditions are the innovative basis. Both industries and academic groups are active in patenting. As a conclusion of this survey, we can assert that biocatalysis is increasingly recognized as a useful tool for asymmetric synthesis and being considered as an innovative option to build IP and protect synthetic routes.
