“…1 H-NMR analysis also indicated tolyporphin-related compounds were in the 90% MeOH fraction of the hexanes partition based on characteristic N-H resonances between −2 to −3 ppm. Distinctive absorption spectral maxima 16,17 at approximately 400 and 676 nm were also hallmarks of tolyporphinrelated compounds and guided their isolation by HPLC. Successive reversed-and normalphase HPLC on these fractions yielded compounds of sufficient purity for spectroscopic and spectrometric characterization.…”

Tolyporphins L–R: Unusual Tetrapyrroles from a Brasilonema sp. of Cyanobacterium

et al. 2019

Tolyporphins L-R (2-8) have been isolated from a mixed cyanobacterium-microbial culture. The structures of tolyporphins L and M have been revised to four constitutional isomers, isolated as two mixtures of dioxobacteriochlorins (2/3 and 4/5). In contrast, tolyporphin P ( 6) is a fully oxidized tetrapyrrole, while tolyporphins Q and R (7 & 8) are oxochlorins. X-ray structures are reported for the first time for tolyporphin A (1), R ( 8), E (9), revealing unexpected stereochemical variation within the series.

“…Based on the principle of ‘similar compatibility’, the CF/PEEK composite interface can be modified by coating the fibre surface with a sizing agent 24 . The compatibility between CF and resin and the interface chemical bonding between CF and resin can be increased, thereby improving the interface performance of the composites 25–27 …”

As a high‐performance thermoplastic polymer, poly(ether‐ether‐ketone) (PEEK) has excellent thermal stability and mechanical properties; it is widely used in the aerospace field. However, PEEK has high viscosity, high processing temperature and poor fluidity in the molten state. In preparing carbon fibre (CF)/PEEK composites, poor impregnation performance will occur, resulting in high porosity and poor mechanical properties of the CF/PEEK composites. This mini‐review focuses on improving the interface of the CF/PEEK composite by coating the CF surface and introduces the preparation of CF/PEEK composites by coating CF with a resin‐based sizing agent, a mixed sizing agent and nanoparticles. Meanwhile, the properties of CF/PEEK composites prepared by different coating methods are compared. © 2022 Society of Industrial Chemistry.

“…More hydrophobic peptide samples (4, 5, and their derivatives) were dissolved in 400 μL of a water/acetonitrile mixture (95:5). 1 H NMR and 13 C{ 1 H} NMR spectra were recorded on a high field Bruker 500 MHz spectrometer equipped with a broadband inverse gradient probe head. Spectra were referenced to the residual solvent signal (CDCl 3 at 7.24 ppm or MeOD at 4.87 ppm).…”

One-Pot Cyclization and Cleavage of Peptides with N-Terminal Cysteine via the N,S-Acyl Shift of the N-2-[Thioethyl]glycine Residue

et al. 2021

We developed a one-pot method for peptide cleavage from a solid support via the N,S -acyl shift of N -2-[thioethyl]glycine and transthioesterification using external thiols to produce cyclic peptides through native chemical self-ligation with the N -terminal cysteine. The feasibility of this methodology is validated by the syntheses of model short peptides, including a tetrapeptide, the bicyclic sunflower trypsin inhibitor SFTI-1, and rhesus Θ-defensin RTD-1. Synthesis of the whole peptide precursor can be fully automated and proceeds without epimerization or dimerization.
