Discovery and evaluation of Ca(v)3.2-selective T-type calcium channel blockers

We identified and characterized a series of pyrrole amides as potent, selective Ca(v)3.2-blockers. This series culminated with the identification of pyrrole amides 13b and 26d, with excellent potencies and/or selectivities toward the Ca(v)3.1- and Ca(v)3.3-channels. These compounds display poor physicochemical and DMPK properties, making their use difficult for in vivo applications. Nevertheless, they are well-suited for in vitro studies. (C) 2017 Elsevier Ltd.

The effect of terminal groups and halogenation of KLVFF peptide on its activity as an inhibitor of beta-amyloid aggregation

The aggregation of A beta peptide into amyloid fibrils in the brain is associated with Alzheimer’s disease (AD). Inhibition of A beta aggregation seemed a potential treatment for AD. It was previously shown that a short fragment of A beta peptide (KLVFF, 16-20) bound A beta inhibited its aggregation. In this work, using KLVFF peptide, we synthesized two peptide families and then evaluated their inhibitory capacities by conventional assays such as thioflavin T (ThT) fluorescence spectroscopy, turbidity measurement, and the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS). The effect of peptide terminal groups on its inhibitory activity was first studied. Subsequently, the influence of halogenated amino acids on peptide anti-aggregation properties was investigated. We found that iodinated peptide with amine in the N and amide in the C termini, respectively, was the best inhibitor of A beta fibers formation. Halogenated peptides seemed to decrease the number of A beta fibrils; however, they did not reduce A beta cytotoxicity. The data obtained in this work seemed promising in developing potential peptide drugs for treatment of AD.

Engineered (Lys)(6)-Tagged Recombinant Sulfide-Reactive Hemoglobin I for Covalent Immobilization at Multiwalled Carbon Nanotubes

The recombinant HbI was fused with a poly-Lys tag ((Lys)(6)-tagged rHbI) for specific-site covalent immobilization on two carbon nanotube transducer surfaces, i.e., powder and vertically aligned carbon nanotubes. The immobilization was achieved by following two steps: (1) generation of amine-reactive ester from the carboxylic acid groups of the surfaces and (2) coupling these groups with the amine groups of the Lys-tag. We analyzed the immobilization process using different conditions and techniques to differentiate protein covalent attachment from physical adsorption. Fourier transform infrared microspectroscopy data showed a 14 cm(-1) displacement of the protein’s amide I and amide II peaks to lower the frequency after immobilization. This result indicates a covalent attachment of the protein to the surface. Differences in the morphology of the carbon substrate with and without (Lys)(6)-tagged rHbI confirmed protein immobilization, as observed by transmission electron microscopy. The electrochemical studies, which were performed to evaluate the redox center of the immobilized protein, show a confinement suitable for an efficient electron transfer system. More importantly, the electrochemical studies allowed determination of a redox potential for the new (Lys)(6)-tagged rHbI. The data show that the protein is electrochemically active and retains its biological activity toward H2S.

Efficient synthesis, spectroscopic characterization and DFT based studies of novel 1-amide 4-sulfonamide-1,2,3-triazole derivatives

In the present study, for the first time 1-amide 4-sulfonamide-1,2,3-triazole scaffolds were synthesized by using an azide-alkyne Huisgen cycloaddition reaction. The target products were obtained in moderate to good yields (45-75%) by using catalytic Cul and green system H2O/EtOH. The easy availability of the inexpensive starting materials, avoiding isolation and handling of hazardous organic azides and mild reaction conditions make this method a valuable tool for generating functionalized 1,2,3-triazole derivatives. The unambiguous characterization of synthesized compounds was accomplished by using various spectroscopic techniques such as H-1 NMR, C-13 NMR, and FT-IR. The information regarding optimized geometry, were obtained by applying DFT/B3LYP-6-31G(d) method. The electrophilicity index, H-1 and C-13 chemical shift values, lithium and sodium ion affinities of the desired product 3b have been also calculated by the mentioned method. As a whole, the calculated results were found in close agreement to that of experimental data. The studies revealed that the compound 3b possesses good Li+ and Na+ affinity and cation pi interaction plays a vital role in the complexation of 3b. For the first time, nucleus-independent chemical shift index was used to confirm the cation pi interaction of 3b. (C) 2019 Elsevier B.V. All rights reserved.

OMS-2/H2O2/Dimethyl Carbonate: An Environmentally-Friendly Heterogeneous Catalytic System for the Oxidative Synthesis of Benzoxazoles at Room Temperature

A manganese octahedral molecular sieve (OMS-2) was found to be an efficient and recyclable heterogeneous catalyst for the oxidative synthesis of benzoxazoles in the gram-scale from phenolic imines at room temperature. H2O2 and biobased reagent dimethyl carbonate (DMC) were successfully employed as the environmentally friendly oxidant and solvent, respectively, in an OMS-2-catalysted redox reaction for the first time. Benzoxazoles could also be obtained from N-substituted 2-aminophenols via Cu(OH)(x)/OMS-2-catalyzed sequential oxidative transformation at elevated temperatures.

DECA, A Comprehensive, Automatic Post-processing Program for HDX-MS Data*

The open-source software, DECA, provides comprehensive back-end analysis of HDX-MS data that addresses the recent recommendations for HDX-MS data analysis and presentation. It provides options for back-exchange correction and rigorous statistical analysis of the significance of differences in exchange. Amide hydrogen-deuterium exchange mass spectrometry (HDX-MS) has become widely popular for mapping protein-ligand interfaces, for understanding protein-protein interactions, and for discovering dynamic allostery. Several platforms are now available which provide large data sets of amide hydrogen/deuterium exchange mass spectrometry (HDX-MS) data. Although many of these platforms provide some down-stream processing, a comprehensive software that provides the most commonly used down-stream processing tools such as automatic back-exchange correction options, analysis of overlapping peptides, calculations of relative deuterium uptake into regions of the protein after such corrections, rigorous statistical analysis of the significance of uptake differences, and generation of high quality figures for data presentation is not yet available. Here we describe the Deuterium Exchange Correction and Analysis (DECA) software package, which provides all these downstream processing options for data from the most popular mass spectrometry platforms. The major functions of the software are demonstrated on sample data.

Cyclobutane-based peptides/terpyridine conjugates: Their use in metal catalysis and as functional organogelators

Two new conjugates, hcptpyDP and hcptpyTP, of a terpyridine derivative incorporating artificial peptide moieties, have been synthesized and their use in the preparation of metal catalysts and organogelators has been investigated. Ru(II) complexes derived from these ligands showed electrochemical behavior and activity as catalysts in the epoxidation of olefins similar to that of Beller’s catalyst. As organogelators, these conjugates were able to gelate a variety of solvents, from toluene to methanol, with satisfactory mgc (minimum gelation concentration) values. The presence of 4′-(4-carboxy)phenylterpyridine (hcptpy) moiety allows tuning the gelling properties and also influences the supramolecular self-assembling mode to produce chiral aggregates with respect to parent peptides DP and TP. In the case of the conjugates, pi-pi interactions provided by the aromatic moieties cooperate with inter-molecular hydrogen bonding between NH and CO in the amide groups. Further properties of peptide/terpyridine conjugates are under investigation in view of future applications. (C) 2018 Elsevier Ltd. All rights reserved.

Biocalcium powder from precooked skipjack tuna bone: Production and its characteristics

Biocalcium (BC) powder from the bones of precooked skipjack tuna was produced and characterized, compared to calcined bone (CB) powder. Higher calcium (40.35%) and phosphorous (15.28%) contents were found in the CB powder, compared to BC powder (26.91 and 12.63%, respectively). Nevertheless, similar Ca/P ratio was observed (1.62-1.65). Mean particle sizes of both powders were 17.07-20.29 mu m. BC powder had higher b* (yellowness) with slightly lower L* (lightness) values than the CB counterpart (p<.05). Both samples showed a characteristic peak of hydroxyapatite in X-ray diffraction patterns, in which the crystallinities of the BC and CB powders were 45.19 and 74.69%, respectively. Amides I, II, and III peaks in Fourier transform infrared spectrum, hydroxyproline, and protein were detected only in the BC powder. BC powder had a low abundance of volatile compounds, including aldehydes, alcohols, and ketones. A negligible amount of volatiles was found in the CB powder. Practical applicationsCalcium supplementation has been increasingly used to alleviate the lack of calcium in the human body, particularly inadequate levels of calcium and poor absorption. Calcium associated with peptides or biocalcium (BC) has a higher advantage in terms of absorption than calcium alone. Precooked skipjack tuna is considered a promising source for BC production due to its abundance. BC with improved color and odor along with increased solubility in gastrointestinal tract can be used as an alternative calcium supplement to tackle the inadequate intake of dietary calcium.

Infrared Fingerprints of n(N) -> sigma*(NH) Hyperconjugation in Hydrazides

An earlier study demonstrated that hyperconjugation operates in hydrazides by analyzing the N-H stretching mode in gas phase infrared (IR) spectroscopy, and then observing two very distinct bands corresponding to isolated isomers experiencing or not the n(N) -> sigma*(N-H) electron delocalization. The present work reports a chemical method to obtain insight on the hyperconjugation in hydraiide derivatives from solution IR spectroscopy. The analogous amides did not show a v(N-H) red-shifted band, as the electron donor orbital in the above hyperconjugative interaction does not exist. In addition, the effect of electron withdrawing groups bonded to a nitrogen atom, namely the trifluoroacetyl and the methanesulfonyl groups, was analyzed on the conformational isomerism and on the ability to induce a stronger hyperconjugation in the resulting compounds.
