Experimental and numerical hydrodynamic studies of ionic liquid-aqueous plug flow in small channels

The hydrodynamic characteristics of liquid-liquid plug flow were studied in microchannels with 0.2 and 0.5 mm ID both experimentally and numerically. For the experiments high speed imaging and bright field micro-Particle Image Velocimetry were used, while the numerical simulations were based on the volume-of-fluid (VOF) method. The two immiscible liquids were a 1 M HNO3 aqueous solution which formed the dispersed plugs and a mixture of 0.2 M n-octyl(phenyl)-N, N-diisobutylcarbamoylmethypho sphine oxide (CMPO) and 1.2 M Tributylphosphate (TBP) in the ionic liquid 1-butyl-3-methylimidazolium bis[(trifluoromethyl) sulfonyl] amide ([C(4)min][NTf2]). The thickness of the film surrounding the plugs, and the plug velocity and length were measured and compared against literature correlations. For the cases studied (0.0224 < Ca < 0.299) it was observed that the liquid film was largely affected by the changes in the shape of the front cap of the plug. The plug length was affected by both the Capillary number and the ratio of the aqueous to ionic liquid phase flow rates while the plug volume depended on the channel diameter and the mixture velocity. The numerical simulations showed that, in agreement with the measurements, a parabolic velocity profile develops in the middle of the plugs while the circulation patterns in the plug are affected by the channel size. The pressure profile along the channel with a series of plugs and slugs was predicted numerically while the pressure drop agreed well with a correlation which included the dimensionless slug length and the ratio Ca/Re.

Which DFT levels of theory are appropriate in predicting the prolyl cis-trans isomerization in solution?

The performances of the M06-2X and omega B97X-D functionals with various basis sets as well as the double-hybrid DSD-PBEP86-D3BJ/cc-pVTZ level of theory with the implicit PCM and SMD solvation methods were assessed for the conformational preferences of Ac-Pro-NHMe in chloroform and water. The M06-2X/def2-TZVP//M06-2X/6-31+G(d) and DSD-PBEP86-D3BJ/cc-pVTZ//M06-2X/6-31+G(d) methods with PCM in chloroform and SMD in water exhibited the best performances for these conformational preferences consistent with experimental results in chloroform and water. As a further step in checking the applicability of these DFT methods, we have undertaken a study of the conformational preferences of Ac-Pro-OMe, Ac-X-OMe, and Ac-X-NHMe (X = Pro derivatives) in chloroform and/or water. Almost the same results were obtained at both levels of theory. The order of the distributions of puckerings depending on the trans and cis peptide bonds was different depending on the substitution position, the chirality, and the solvent polarity. The cis populations of the prolyl peptide bond for Ac-X-OMe and Ac-X-NHMe (X = Pro and its derivatives) were well predicted with RMSD < 6% in chloroform and water, compared with the experimental values. In addition, the calculated barriers Delta G(c-t)double dagger to the cis-to-trans isomerization of the prolyl peptide bond for Ac-Pro-NHMe, Ac-X-OMe (X = Pro, Hyp, Flp, and flp), and Ac-X-NHMe (X = 5-Mep, 5-Tbp, and 5-tbp) in chloroform and/or water were consistent with the experimental values within 1 kcal mol(-1). Hence, the M06-2X/def2-TZVP//M06-2X/6-31+G(d) and DSD-PBEP86-D3BJ/cc-pVTZ//M06-2X/6-31+G(d) methods with PCM in chloroform and SMD in water appeared to be appropriate in predicting the conformational preferences and the cis-trans isomerization of the longer peptides containing Pro or Pro derivatives in chloroform and water.

A Computationally Designed Peptide Derived from Escherichia coli as a Potential Drug Template for Antibacterial and Antibiofilm Therapies

Computer-aided screening of antimicrobial peptides (AMPs) is a promising approach for discovering novel therapies against multidrug-resistant bacterial infections. Here, we functionally and structurally characterized an Escherichia coli-derived AMP (EcDBS1R5) previously designed through pattern identification [alpha-helical set (KK[ILV]((3))[AILV])], followed by sequence optimization. EcDBS1R5 inhibited the growth of Gram-negative and Gram-positive, susceptible and resistant bacterial strains at low doses (2-32 mu M), with no cytotoxicity observed against non-cancerous and cancerous cell lines in the concentration range analyzed (<100 mu M). Furthermore, EcDBS1R5 (16 mu M) acted on Pseudomonas aeruginosa pre-formed biofilms by compromising the viability of biofilm-constituting cells. The in vivo antibacterial potential of EcDBS1R5 was confirmed as the peptide reduced bacterial counts by two-logs 2 days post-infection using a skin scarification mouse model. Structurally, circular dichroism analysis revealed that EcDBS1R5 is unstructured in hydrophilic environments, but has strong helicity in 2,2,2-trifluoroethanol (TFE)/water mixtures (v/v) and sodium dodecyl sulfate (SDS) micelles. The TFE-induced nuclear magnetic resonance structure of EcDBS1R5 was determined and showed an amphipathic helical segment with flexible termini. Moreover, we observed that the amide protons for residues Met2-Ala8, Arg10, Ala13-A1a16, and Trp19 in EcDBS IRS are protected from the solvent, as their temperature coefficients values are more positive than -4.6 ppb center dot K-1. In summary, this study reports a novel dual-antibacterial/antibiofilm alpha-helical peptide with therapeutic potential in vitro and in vivo against clinically relevant bacterial strains.

Selectively convert fructose to furfural or hydroxymethylfurfural on Beta zeolite: The manipulation of solvent effects

The selective synthesis of furfural or hydroxymethylfurfural (HMF) from fructose on single catalyst (Beta zeolite, 1113) is challenging task. However, in this study, selectivity of H beta zeolite was discovered easily to tune by solvent effects. Strong solvent effects on the selectivity of fructose conversion were observed in different manners depending on the solvent used. It was shown that the coordinated state of framework aluminum, induced by solvent effects, has a major impact on the selectivity. The solvents with amide group were discovered to induce the reversible tetrahedral-octahedral framework aluminum transformation, but the configuration of aluminum was no influenced by other solvents such as gamma-butyrolactone (GBL). Compared with other solvents, the GBL was not able to enhance turnover frequency (TOF) value of reaction but also suppress the degradation of furfural. Interestingly, a considerable yield of furfural (50.25%) was obtained combined with tetrahedral and octahedral framework aluminum active sites in GBL, while high selectivity of HMF (83.3%) was achieved in presence of single tetrahedral framework aluminum over H beta in NMP.

Ribosomal Formation of Thioamide Bonds in Polypeptide Synthesis

It has been well established that the ribosome can accept various nucleophiles on the Xacyl-tRNA in the A site during elongation, where X can be amino, N-alkyl-amino, hydroxy, and thiol groups. However, it remains elusive that the ribosome is able to accept an electrophile in the P site other than the carboxyl group during elongation. Here we report ribosomal formation of a thioamide bond in the mRNA-dependent polypeptide synthesis. In this study, amino(carbothio)-acyl-tRNA was prepared by flexizyme and used for the expression of peptides containing a thioamide bond in the nascent peptide chain. We give strong evidence that the thioamide-peptide was formed but accompanied by the amide counterpart due to rapid carbo(S-to-O) exchange during the preparation of amino(carbothio)acyl-tRNA. We also demonstrate the ribosomal formation of thioamide and N-methyl-thioamide bonds in linear as well as macrocyclic peptide scaffolds in the mRNA-dependent manner, showing its potential for applications in peptide-based drug discovery and studying peptide/protein structure and function.

Optical Kerr effect spectroscopy of CS2 in monocationic and dicationic ionic liquids: insights into the intermolecular interactions in ionic liquids

A comparative study of the intermolecular dynamics of CS2 in monocationic and dicationic ionic liquids (ILs) was performed using optical heterodyne-detected Raman-induced Kerr effect spectroscopy (OHD-RIKES). The reduced spectral densities (RSDs) of mixtures of CS2 in 1-alkyl-3-methylimidazolium bis[(trifluoromethane)sulfonyl]amide ([C(n)C(1)im][NTf2] for n = 3-5) and 1,2n-bis(3-methylimidazolium-1-yl) alkane bis[(trifluoromethane)sulfonyl]amide ([(C(1)im)(2)C-2n][NTf2](2) for n = 3-5) were investigated as a function of concentration at 295 K. An additivity model was used to obtain the CS2 contribution to the RSD of a mixture in the 0-200 cm(-1) region. One of the aims of this study is to show how CS2 can be used as a probe of intermolecular/interionic interactions in ILs. The concentrations were chosen such that the CS2-to-imidazolium ring mole fraction of a mixture with [(C(1)im)(2)C-2n][NTf2](2) (DIL(2n)) is the same as that of a mixture with [C(n)C(1)im][NTf2] (MIL(n)). As found previously for CS2 in monocationic ILs, the intermolecular spectrum of CS2 in dicationic ILs is lower in frequency and narrower than that of neat CS2. The new result is that the intermolecular spectrum of CS2 is higher in frequency in DIL(2n) than in the corresponding MIL(n), indicating that CS2 molecules experience a stiffer potential in dicationic ILs than in monocationic ILs. The intermolecular dynamics of CS2 being higher in frequency in DIL(2n) than in MIL(n) is consistent with recent molecular dynamics simulations (Lynden-Bell and Quitevis, J. Chem. Phys., 2018, 148, 193844) that show the stiffer potential is the result of greater confinement of CS2 in DIL(2n) than in MIL(n). We also show in this study how effects due to dilution and the intermolecular potential seen by a solute molecule in solution are unraveled.

Evolving Accelerated Amidation by SpyTag/SpyCatcher to Analyze Membrane Dynamics

SpyTag is a peptide that forms a spontaneous amide bond with its protein partner SpyCatcher. This protein superglue is a broadly useful tool for molecular assembly, locking together biological building blocks efficiently and irreversibly in diverse architectures. We initially developed SpyTag and SpyCatcher by rational design, through splitting a domain from a Gram-positive bacterial adhesin. In this work, we established a phage-display platform to select for specific amidation, leading to an order of magnitude acceleration for interaction of the SpyTag002 variant with the SpyCatcher002 variant. We show that the 002 pair bonds rapidly under a wide range of conditions and at either protein terminus. SpyCatcher002 was fused to an intimin derived from enterohemorrhagic Escherichia coli. SpyTag002 reaction enabled specific and covalent decoration of intimin for live cell fluorescent imaging of the dynamics of the bacterial outer membrane as cells divide.

Asymmetric syntheses of the N-terminal alpha-hydroxy-beta-amino acid components of microginins 612, 646 and 680

The asymmetric syntheses of the N-terminal alpha-hydroxy-beta-amino acid components of microginins 612, 646 and 680 are reported. Conjugate addition of lithium (R)-N-benzyl-N-(alpha-methylbenzyl)amide to the requisite (E)-alpha,beta-unsaturated ester followed by in situ enolate oxidation with (-)-(camphorsulfonyl)oxaziridne (CSO) gave the corresponding anti-alpha-hydroxy-beta-amino esters. Sequential Swern oxidation followed by diastereoselective reduction gave the corresponding syn-alpha-hydroxy-beta-amino esters. Subsequent N-debenzylation (i.e., hydrogenolysis for microginin 612, and NaBrO3-mediated oxidative N-debenzylation for microginins 646 and 680) followed by acid catalysed ester hydrolysis gave the corresponding syn-alpha-hydroxy-beta-amino acids, the N-terminal components of microginins 612, 646 and 680, in good yield. An analogous strategy for elaboration of the enantiopure anti-alpha-hydroxy-beta-amino esters facilitated the asymmetric synthesis of the corresponding C(2)-epimeric alpha-hydroxy-beta-amino acids.
