Bacteriophage-encoded endolysins can recognize and bind specific bacteria, and act to cleave the glycosidic and/or amide bonds in the peptidoglycan (PG) bacterial cell wall. Cleavage of the cell wall generally results in the death of the bacteria. Their utility as bacteriolytic agents could be exploited for human and veterinary medicines as well as various biotechnological applications. As interest grows in the commercial uses of these proteins, there has been much effort to successfully employ rational design and engineering to produce endolysins with bespoke properties. In this review, we interrogate the current structural data and identify structural features that would be of benefit to engineering the activity and specificity of phage endolysins. We show that the growing body of structural data can be used to predict catalytic residues and mechanism of action from sequences of hypothetical endolysins, and probe the importance of secondary structure repeats in bacterial cell wall-binding domains.

Temperature-dependency of back-extraction behavior of inert platinum group metals (PGMs) like Ru(III) and Rh(III) has been investigated in a biphasic system consisting of H2C2O4(aq) and betainium bis(trifluoromethylsulfonyl)amide ([Hbet][Tf2N]) after extracting these PGMs as well as that of non-inert Pd(II). At 298 K, Pd(II) in [Hbet][Tf2N] phase was stripped high efficiency (78.8%) by 0.1 M H2C2O4 within 2 min. In contrast, back-extraction of Rh(III) and Ru(III) did not proceed at all in practice under the same condition, demonstrating the inertness of these PGMs. When the sample temperature was risen up to 353 K, the stripping of Rh(III) was promoted, and completed within 300 min at 353 K. The stripping efficiency of Ru(III) was still as low as 24.2% at 300 min and 353 K, and took 48 h in use of 1 M H2C2O4(aq) for completion. Further mechanistic studies by means of UV-vis absorption spectroscopy clarified that the complexation of these PGMs and oxalate ion (C2O4 (2-)) is rate-determining in their stripping, and is successfully accelerated and enhanced by elevating the temperature and increasing the concentration of the stripping agent.

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. you can also check out more blogs about 2491-20-5. Quality Control of H-Ala-OMe.HCl.

M-2 muscarinic acetylcholine receptor (M2R) is a prototypical G protein-coupled receptor (GPCR) that responds to acetylcholine and mediates various cellular responses in the nervous system. Here, we used attenuated total reflection-Fourier transform infrared spectroscopy analyses on M2R reconstituted in a lipid membrane to understand the molecular mechanism behind the ligand binding-induced conformational changes. Upon agonist binding, M2R shows large spectral change of the amide-I band corresponding to backbone C=O stretch, which likely connects with the receptor activation in the lipid environment. These results pave the way to probe effects of different ligand binding on GPCRs using vibrational spectroscopy.

Pharmacological analysis of the transmembrane action potential configuration in myoepithelial cells of the spontaneously beating heart of the ascidian Styela rustica in vitro

The mechanisms of action potential (AP) generation in the myoepithelial cells of the tunicate heart are not yet well understood. Here, an attempt was made to elucidate these mechanisms by analyzing the effects of specific blockers of K+, Na+ and Ca2+ currents on the configuration of transmembrane APs and their frequency in the spontaneously beating ascidian heart. In addition, an immunocytochemical analysis of heart myoepithelial cells was performed. Staining with anti-FMRF-amide and anti-tubulin antibodies did not reveal any nerve elements within the heart tube. Treatment with 1 mmol l(-1) TEA (I-K blocker) resulted in depolarization of heart cell sarcolemma by 10 mV, and inhibition of APs generation was recorded after 3 min of exposure. Prior to this moment, the frequency of AP generation in a burst decreased from 16-18 to 2 beats min(-1) owing to prolongation of the diastole. After application of ivabradine (3 or 10 mu mol l(-1)), the spontaneous APs generation frequency decreased by 24%. Based on these results and published data, it is concluded that the key role in the automaticity of the ascidian heart is played by the outward K+ currents, Na+ currents, activated hyperpolarization current I-f and a current of unknown nature I-X.

Novel amide and imidazole compounds as potent hematopoietic prostaglandin D-2 synthase inhibitors

In seeking novel and potent small molecule hematopoietic prostaglandin D-2 synthase (H-PGDS) inhibitors as potential therapies for PGD(2)-mediated diseases and conditions, we explored a series comprising multiple aryl/heteroaryl rings attached in a linear arrangement. Each compound incorporates an amide or imidazole linker between the pyrimidine or pyridine core ring and the tail ring system. We synthesized and screened twenty analogs by fluorescence polarization binding assay, thermal shift assay, glutathione S-transferase inhibition assay, and a cell-based assay measuring suppression of LPS-induced PGD(2) stimulation. Amide analogs show ten-fold greater shift in the thermal shift assay in the presence of glutathione (GSH) versus the same assay run in the absence of GSH. The imidazole analogs did not produce a significant change in thermal shift between the two assay conditions, suggesting a possible stabilization effect of the amide linker in the synthase-GSH-inhibitor complex. Imidazole analog 23, (KMN-010034) demonstrates superior potency across the in vitro assays and good in vitro metabolic stability in both human and guinea pig liver microsomes.

Effects of Amide-Based modifiers on surface activation and devulcanization of rubber

This paper examines the mechanisms of interaction between two modifiers in asphalt binder: an amide-based bio-modifier, and natural rubber vulcanized by sulfur crosslinks. The amide-rich bio-modifier surface-activates the rubber, cleaving the disulfide bonds and leading to partial surface devulcanization. Computational modeling and laboratory experiments were used to evaluate the devulcanization mechanism and its effects. Results show that non-covalent interaction between the -NH2 site of the bio-modifier and the S-S crosslink of the rubber is stronger than with the C-S part of the rubber, which can potentially induce partial devulcanization. This phenomenon is reflected in the empirical results: a reduction in viscosity, due to devulcanization; and an increased resistance to fatigue, due to improved interaction between rubber and bitumen. This study provides an in-depth understanding of the surface devulcanization mechanism of rubber, in addition to insights into the complex devulcanization process happening inside a bio-modified mixture of rubber and asphalt binder. The results of this study help expand the knowledge of bio-modifiers and present a new approach for devulcanization.

Synthesis of pi-conjugated poly(arylene)s by polycondensation of 1,4-bis(3-methylpyridin-2-yl)benzene and aryl dibromides through regiospecific C-H functionalization process

On the basis of the Ru-catalyzed regiospecific direct double arylation of benzene rings possessing 3-methylpyridin-2-yl substituents to produce 1-aryl-2-(3-methylpyridin-2-yl)benzene derivatives, the synthesis of poly(p-phenylene) derivatives having 2,5-bis(3-methylpyridin-2-yl) substituents is described. The reaction of 1,4-bis(3-methylpyridin-2-yl)benzene with bromobenzene (2 equiv) was carried out in the presence of [RuCl2(eta(6)-C6H6)](2) (5 mol %) in 1-methyl-2-pyrrolidone at 120 degrees C for 24 h to produce 1,4-bis(3-methylpyridin-2-yl)-2,5-diphenylbenzene in 99% yield as a sole product. Neither 2,6-diphenylated nor further phenylated products was produced under the examined conditions. This regiospecific double arylation process was then applied to the synthesis of pi-conjugated polymers by use of aryl dibromides such as 1,4-dibromobenzene, 2,7-dibromo-9,9-dihexylfluorene, and 2,5-dibromothiophene. For example, a polymer was obtained in 73% yield by using 1,4-dibromobenzene, whose M-n and M-w/M-n were estimated to be 3300 and 1.51, respectively. The bathochromic shift of the ultraviolet (UV)-visible absorption spectrum with respect to that of the model compound, 1,4-bis(3-methylpyridin-2-yl)-2,5-diphenylbenzene, indicated the extension of the pi-conjugation. The blue fluorescence was also observed for the polymer upon the UV irradiation. (c) 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2018, 56, 2771-2777

Formal Deoxygenative Hydrogenation of Lactams Using (PNP)-P-H-Pincer Ruthenium Complexes under Nonacidic Conditions

A formal deoxygenative hydrogenation of amides to amines with RuC12(NHC)(PNHP) (NHC = 1,3-dimethylimizadol-2-ylidene, PNHP = bis(2-diphenylphosphinoethyl)amine) is described. Various secondary amides, especially NHlactams, are reduced with H2 (3.0-5.0 MPa) to amines at a temperature range of 120-150 C with 1.0-2.0 mol % of PNHP Ru catalysts in the presence of Cs2CO3. This process consists of (1) deaminative hydrogenation of secondary amides to generate primary amines and alcohols, (2) dehydrogenative coupling of the transient amines with alcohols to generate imines, and (3) hydrogenation of imines to give the formally deoxygenated secondary amine products.
