Lopez-Vidal, Eva M.;Schissel, Carly K.;Mohapatra, Somesh;Bellovoda, Kamela;Wu, Chia-Ling;Wood, Jenna A.;Malmberg, Annika B.;Loas, Andrei;Gomez-Bombarelli, Rafael;Pentelute, Bradley L. research published 《 Deep Learning Enables Discovery of a Short Nuclear Targeting Peptide for Efficient Delivery of Antisense Oligomers》, the research content is summarized as follows. Therapeutic macromols. such as proteins and oligonucleotides can be highly efficacious but are often limited to extracellular targets due to the cell′s impermeable membrane. Cell-penetrating peptides (CPPs) are able to deliver such macromols. into cells, but limited structure-activity relationships and inconsistent literature reports make it difficult to design effective CPPs for a given cargo. For example, polyarginine motifs are common in CPPs, promoting cell uptake at the expense of systemic toxicity. Machine learning may be able to address this challenge by bridging gaps between exptl. data in order to discern sequence-activity relationships that evade our intuition. Our earlier data set and deep learning model led to the design of miniproteins (>40 amino acids) for antisense delivery. Here, we leveraged and expanded our model with data augmentation in the short CPP sequence space of the data set to extrapolate and discover short, low-arginine-content CPPs that would be easier to synthesize and amenable to rapid conjugation to desired cargo, and with minimal in vivo toxicity. The lead predicted peptide, termed P6, is as active as a polyarginine CPP for the delivery of an antisense oligomer, while having only one arginine side chain and 18 total residues. We determined the pentalysine motif and the C-terminal cysteine of P6 to be the main drivers of activity. The antisense conjugate was able to enhance corrective splicing in an animal model to produce functional eGFP in heart tissue in vivo while remaining nontoxic up to a dose of 60 mg/kg. In addition, P6 was able to deliver an enzyme to the cytosol of cells. Our findings suggest that, given a data set of long CPPs, we can discover by extrapolation short, active sequences that deliver antisense oligomers.

Lu, Benjamin L.;Li, Freda F.;Kelch, Inken D.;Williams, Geoffrey M.;Dunbar, P. Rod;Brimble, Margaret A. research published 《 Investigating the individual importance of the Pam₂Cys ester motifs on TLR2 activity》, the research content is summarized as follows. TLR2 agonists are at the forefront of vaccine research for a plethora of diseases, in particular they offer a promising tool for the treatment of cancer. A detailed knowledge of their structure-activity relationship informs the methodical design of vaccine constructs that include TLR2 agonists. Herein we report the design, synthesis, and biol. evaluation of analogs of the TLR2 agonist Pam₂Cys to further probe structure-activity relationships. These analogs replace one or other of the two ester groups with ether functionalities to elucidate the role of the carbonyls on TLR2 activity. Through this we demonstrate that the C3 ester carbonyl is dispensable, but the C2 carbonyl is essential for activity.

PEP27, a 27-amino acid (aa) peptide secreted by Streptococcus pneumoniae, is an autolytic peptide that functions as a major virulence factor. To develop a clin. applicable antimicrobial peptide (AMP), we designed PEP27 analogs with Trp substitutions to enhance its antimicrobial activity compared to that of PEP27. Particularly, PEP27-2 showed strong antimicrobial activity against a wide variety of bacteria, including multidrug-resistant (MDR) bacteria. It was found that the antimicrobial activity of PEP27-2 was increased by substituting Trp for the aa at the middle position of PEP27. We found that PEP27-2 acts as an effective cell-penetrating peptide in bacterial and mammalian cells. Here, we proved that s.c. infection with MDR Staphylococcus aureus induced skin lesions such as skeletal muscle damage, deep inflammation, and necrosis of the overlaying dermis in mice. Combination treatment with antibiotics revealed synergistic effects, remarkably reducing abscess size and improving the bacteria removal rate from the infection site. Moreover, PEP27-2-antibiotic combination treatment reduced inflammation, lowering levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, inducible NO synthase (iNOS), and cyclooxygenase (COX-2) in skin abscess tissue. The results suggest that the PEP27-2 peptide is a promising therapeutic option for combating MDR bacterial strains by enhancing antibiotic penetration and protecting against MDR bacteria.

Kim, Kyunghee;Kloxin, Christopher J.;Saven, Jeffery G.;Pochan, Darrin J. research published 《 Nanofibers produced by electrospinning of ultrarigid polymer rods made from designed peptide bundlemers》, the research content is summarized as follows. Mimicking the hierarchical assembly of natural fiber materials is an important design challenge in the manufacturing of nanostructured materials with biomols. such as peptides. Here, we produce nanofibers with control of structure over multiple length scales, ranging from peptide mol. assembly into supramol. building blocks called “bundlemers,” to rigid-rod formation through a covalent connection of bundlemer building blocks, and, ultimately, to uniaxially oriented fibers made with the rigid-rod polymers. The peptides are designed to phys. assemble into coiled-coil bundles, or bundlemers, and to covalently interact in an end-to-end fashion to produce the rigid-rod polymer. The resultant rodlike polymer exhibits a rigid, cylindrical nanostructure confirmed by transmission electron microscopy (TEM) and, correspondingly, exhibits shear-thinning behavior at low shear rates observed in many nanoscopic rod systems. The rigid-rod chains are further organized into final fiber materials via electrospinning processing, all the while preserving their unique rodlike structural characteristics. Morphol. and structural investigations of the nanofibers through SEM, transmission electron microscopy, and X-ray scattering, as well as mol. characterization via Fourier transform IR (FTIR) and Raman spectroscopy, show that continuous nanofibers are composed of oriented rigid-rod chains constituted by α-helical peptides within bundle building blocks. Mech. properties of electrospun fibers are also presented. The ability to produce nanofibers from the oriented rigid-rod polymer reveals bundlemer chains as a viable tool for the development of new fiber materials with targeted structure and properties.

Kobayashi, Daishiro;Kohmura, Yutaka;Sugiki, Toshihiko;Kuraoka, Eisuke;Denda, Masaya;Fujiwara, Toshimichi;Otaka, Akira research published 《 Peptide cyclization mediated by metal-free S-arylation: S-protected cysteine sulfoxide as an umpolung of the cysteine nucleophile》, the research content is summarized as follows. Covalent linking of side chains provides a method to produce cyclic or stapled peptides that are important in developing peptide-based drugs. A variety of crosslinking formats contribute to fixing the active conformer and prolonging its biol. activity under physiol. conditions. One format uses the cysteine thiol to participate in crosslinking through nucleophilic thiolate anions or thiyl radicals to form thioether and disulfide bonds. Removal of the S-protection from an S-protected Cys derivative generates the thiol, which functions as a nucleophile. S-Oxidation of a protected Cys allows the formation of a sulfoxide that operates as an umpolung electrophile. Herein, the applicability of S-p-methoxybenzyl Cys sulfoxide (Cys(MBzl)(O)) to the formation of a thioether linkage between tryptophan and Cys has been investigated. The reaction of peptides containing Cys(MBzl)(O) and Trp with trifluoromethanesulfonic acid (TFMSA) or methanesulfonic acid (MSA) in TFA in the presence of guanidine hydrochloride (Gn · HCl) proceeded to give cyclic or stapled peptides possessing the Cys-Trp thioether linkage. In this reaction, strong acids such as TFMSA or MSA are necessary to activate the sulfoxide. Addnl., Gn · HCl plays a critical role in producing an electrophilic Cys derivative that combines with the indole by aromatic electrophilic substitution. The findings led us to conclude that the less-electrophilic Cys(MBzl)(O) serves as an acid-activated umpolung of a Cys nucleophile and is useful for S-arylation-mediated peptide cyclization.

Koshti, Bharti;Kshtriya, Vivekshinh;Naskar, Soumick;Narode, Hanuman;Gour, Nidhi research published 《 Controlled aggregation properties of single amino acids modified with protecting groups》, the research content is summarized as follows. The self-assembly of modified single amino acids has gained substantial attention due to their ease of synthesis, biocompatibility and ability to assemble into distinct structures which can potentially be used for a wide range of applications. Herein, we report the self-assembly of modified single amino acids, i.e. charged aliphatic and aromatic amino acids, which are functionalized with different protecting groups such as 9-fluorenylmethoxycarbonyl (Fmoc), tert-butyloxycarbonyl (Boc), N-carboxybenzyl (Cbz) and tert-Bu (tBu) into distinct structures. The self-assembled structures formed by these modified charged aliphatic and aromatic single amino acids were very interesting and distinct, and also showed the propensity of controlled morphol. transitions at varying concentrations and temperatures The modified single amino acids self-assembled into different well-defined morphologies such as spheres, flowers, fibers, rods and unusual broom-like structures as characterized by various microscopic techniques. The solution state ¹H-NMR, ATR-FTIR studies and control experiments with tannic acid further provided useful insights into the role of intermol. interactions which governs the process of self-assembly and implicates the crucial role of pi-pi stacking and hydrogen bonding in structure formation.

The resultant rodlike polymer exhibits a rigid, cylindrical nanostructure confirmed by transmission electron microscopy (TEM) and, correspondingly, exhibits shear-thinning behavior at low shear rates observed in many nanoscopic rod systems. The rigid-rod chains are further organized into final fiber materials via electrospinning processing, all the while preserving their unique rodlike structural characteristics. Morphol. and structural investigations of the nanofibers through SEM, transmission electron microscopy, and X-ray scattering, as well as mol. characterization via Fourier transform IR (FTIR) and Raman spectroscopy, show that continuous nanofibers are composed of oriented rigid-rod chains constituted by α-helical peptides within bundle building blocks. Mech. properties of electrospun fibers are also presented. The ability to produce nanofibers from the oriented rigid-rod polymer reveals bundlemer chains as a viable tool for the development of new fiber materials with targeted structure and properties.

Category: indole-building-block, Nalpha-FMOC-L-Tryptophan,also known as Fmoc-Trp-OH， is a useful research compound. Its molecular formula is C26H22N2O4 and its molecular weight is 426.5 g/mol. The purity is usually 95%.
Nα-Fmoc-L-Tryptophan is an N-Fmoc protected form of L-Tryptophan (T947210). L-Tryptophan is an essential amino acid that is important for cell proliferation and the biosynthesis of proteins. It is a precursor to Serotonin (HCl: S274980), a neurotransmitter that compound that aids in sleep and mental state. L-Tryptophan is also thought to cause eosinophilia-myalgia syndrome.
Fmoc-Trp-OH is an amino acid derivative
Fmoc-L-Trp-OH is an amide that contains a low bioavailability and inhibits the transfer of amino acids to ribosomes. It has been shown to inhibit the growth of cancer cells in cell culture and to have antimicrobial activity. Fmoc-L-Trp-OH is synthesized by reacting Naphthalene with glycine, followed by hydrolysis of the ester group under trifluoroacetic acid. The product is then conjugated with a polypeptide. This method of synthesis was developed as a way to produce peptides that are difficult to synthesize using solid-phase chemistry., 35737-15-6.
