Molecular dynamics study of coil-to-globule transition in a thermo-responsive oligomer bound to various surfaces: hydrophilic surfaces stabilize the coil form

The structural and dynamical properties of 40-mer of thermo-responsive polymer PNIPAM covalently bound to different surfaces have been studied, at different temperatures, by means of molecular dynamics simulations. Evolution of the radius of gyration, R-g, of the polymer chain and radial distribution functions (RDFs) calculated for the carbon atoms of the PNIPAM backbone with water oxygens and for the hydrogen atom of the amide groups with water oxygens indicate that functionalized surfaces affect the coil-to-globule transition of PNIPAM, by means of electrostatic interactions, increasing the lower critical solution temperature (LCST) of the polymer. Such interactions, mainly represented by a H-bond, hinder the transition in the globular form while hydrophobic groups on the surface, such as -OCH3, contribute to the globular collapse. A significant alteration in the arrangement of water molecules around the polymer is testified by: (i) the absence of the second peak in the RDF between the C atoms of the PNIPAM backbone and the O atoms of water at the same temperature at which the radius of gyration decreases; (ii) the height of both the first and the second peak of the RDF between the H atom of the amide groups and water O atoms decreases when the temperature increases above the LCST. Finally, the H-bond autocorrelation function indicates that: (i) hydrogen bonds between the bound-to-surface PNIPAM acceptor groups (O?C?) and the H atoms of water molecules are less persistent than H-bonds formed between the free PNIPAM acceptor groups and water; (ii) H-bonds between the PNIPAM acceptor groups and hydroxyl groups on the quartz surface are longer lived than those formed on graphene oxide.

Solvation of Amides in DMSO and CDCl3: An Attempt at Quantitative DFT-Based Interpretation of H-1 and C-13 NMR Chemical Shifts

The study concerns N-methyl-2-pyrrolidinone, N,N-dimethylformamide, 2-pyrrolidinone, N-methylformamide, and formamide in DMSO-d(6) and CDCl3 solutions. It has been shown that the results of DFT calculations [B3LYP and/or PBEO 6-311++G(2d,p), PCM] of molecular geometries and magnetic shielding are able to reproduce very well the amide H-1 NMR and C-13 NMR chemical shifts measured in these solvents provided that the specific solvation of the solute molecules and their association are taken into account and also that comparison of the experimental and theoretical data is carefully done. Analysis of the chemical shift data points out that in CDCl3 solutions primary and secondary amides are partially associated and that their carbonyl oxygen lone electron pairs are specifically solvated by solvent molecules. At the same time, association of the amides seems to be of minor importance in DMSO, while their N-H hydrogens form strong hydrogen bonds with solvent molecules.

Diphenylsilane as a coupling reagent for amide bond formation

A simple procedure for amide bond formation using diphenylsilane as a coupling reagent is described. This methodology enables the direct coupling of carboxylic acids with primary and secondary amines, releasing only hydrogen and a siloxane as by-products. Only one equivalent of each partner is needed, providing a more sustainable amidation method producing minimal wastes. This methodology was also extended to the synthesis of peptides and lactams by addition of Hunig’s base (DIPEA) and 4-dimethyl-aminopyridine (DMAP).

Evaluating the rote of a urea-like motif in enhancing the thermal and mechanical strength of supramolecular gels

The geometry and spatial orientation of gelator molecules and the mode of various intermolecular non-covalent interactions are the key parameters that dictate the structure and properties of low molecular weight gelators (LMWGs). The effect of intermolecular non-covalent interactions in tuning the gelation properties was analysed for dipyridyl hydrazone (HL1) with an amide-like hydrogen bonding moiety and semicarbazone (HL2) with a urea-like motif. The gelation properties of the hydrazone and semicarbazone compounds were studied in a series of solvents and solvent mixtures and the SEM images of the xerogels revealed that the morphology of the HL2 gelator was more fibrous in nature compared to HL1. The mechanical and thermal stability of HL2 was higher than HL1, which was confirmed by rheology and gel-sol transition temperature experiments, respectively. The key non-covalent interactions responsible for gel formation were assigned using X-ray diffraction techniques and the results were corroborated with the gelation properties. The stimuli-responsive properties of the gelators were studied by analysing the effect of metal salts and anions on the gelation properties of HL1 and HL2 and the results indicated that metal complexation disrupted the gel network whereas the addition of anions did not alter the gelation ability of the gelators. The tuning of gelation properties by metal complexation and the comparison of intermolecular non-covalent interactions of the gelators enabled us to identify the key parameters responsible for gel-network formation in HL1 and HL2.

Relevance of Peroxisome Proliferator Activated Receptors in Multitarget Paradigm Associated with the Endocannabinoid System

Cannabinoids have shown to exert their therapeutic actions through a variety of targets. These include not only the canonical cannabinoid receptors CB1R and CB2R but also related orphan G protein-coupled receptors (GPCRs), ligand-gated ion channels, transient receptor potential (TRP) channels, metabolic enzymes, and nuclear receptors. In this review, we aim to summarize reported compounds exhibiting their therapeutic effects upon the modulation of CB1R and/or CB2R and the nuclear peroxisome proliferator-activated receptors (PPARs). Concomitant actions at CBRs and PPAR alpha or PPAR gamma subtypes have shown to mediate antiobesity, analgesic, antitumoral, or neuroprotective properties of a variety of phytogenic, endogenous, and synthetic cannabinoids. The relevance of this multitargeting mechanism of action has been analyzed in the context of diverse pathologies. Synergistic effects triggered by combinatorial treatment with ligands that modulate the aforementioned targets have also been considered. This literature overview provides structural and pharmacological insights for the further development of dual cannabinoids for specific disorders.

Hydrogen bonding elements, pi – hole functional moieties and C(3)v tripodal scaffold controlled turn-on cyanide and turn-off azide selective receptors

Here in, we are reporting electron deficient amide and sulfonamide based tripodal receptors L, L-1,L-2 and L-3. Systematic studies show a strong selectivity towards cyanide and azide anions. Detailed UV-Visible and fluorescent spectrometric investigation shows the amide based tripodal receptors Land L-3 acts as a colori metric and turn-on fluorescent chemo-sensor for cyanide, and the sulfonamide based tripodal receptors L-1 and L-2 acts as a colorirnetric and turn-off fluorescent chemo-sensor for azide. At the end we have successfully prepared tripodal receptors for a particular anion with judicious choice of recognition elements such as hydrogen bonding amide/sulfonamide moiety, electron deficient pentafluorophenyl functionality for anion-pi interaction and the well defined C(3)v symmetric tripodal backbone for perfect recognition.

Visible-Light-Induced Remote C(sp(3))-H Pyridylation of Sulfonamides and Carboxamides

Visible-light-induced site-selective C(sp(3))-H pyridylation of amides has been accomplished using N-amidopyridinium salts. The N-centered radicals generated by the single-electron reduction of N-amidopyridinium substrates undergo 1,5-hydrogen atom transfer to form alkyl radical intermediates. Excellent C4-selectivity in radical trapping with pyridinium salts is observed for the alkyl radicals to provide delta-pyridyl sulfonamides and gamma-pyridyl carboxamides. The utility is demonstrated by offering a practical approach for the late-stage functionalization of complex amide derivatives.

Determination of Zoledronic Acid and Creatinine by Hydrophilic Chromatography

We propose a version of the simultaneous determination of zoledronic acid and creatinine in serum and plasma samples by hydrophilic chromatography (HILIC). Factors affecting the determination of zoledronic acid were found: the composition and concentration of the buffer solution, the nature of the stationary phase, the presence of tartaric acid in the eluent as a complexing agent to prevent the complexation of zoledronic acid with metal ions. We determined the linear concentration ranges for zoledronic acid and creatinine and their limits of detection. The following conditions for chromatographic analysis were found: amide stationary phase; a 5 mM phosphate buffer solution, 2 mM tartaric acid (pH 7.0)/CH3CN; gradient 90-70% of CH3CN.

Processable High Electron Mobility pi-Copolymers via Mesoscale Backbone Conformational Ordering

The synthesis and experimental/theoretical characterization of a new series of electron-transporting copolymers based on the naphthalene bis(4,8-diamino-1,5-dicarboxyl)amide (NBA) building block are reported. Comonomers are designed to test the emergent effects of manipulating backbone torsional characteristics, and density functional theory (DFT) analysis reveals the key role of backbone conformation in optimizing electronic delocalization and transport. The NBA copolymer conformational and electronic properties are characterized using a broad array of molecular/macromolecular, thermal, optical, electrochemical, and charge transport techniques. All NBA copolymers exhibit strongly aggregated morphologies with significant nanoscale order. Copolymer charge transport properties are investigated in thin-film transistors and exhibit excellent electron mobilities ranging from 0.4 to 4.5 cm(2) V-1 s(-1). Importantly, the electron transport efficiency correlates with the film mesoscale order, which emerges from comonomer-dependent backbone planarity and extension. These results illuminate the key NBA building block structure-morphology-bulk property design relationships essential for processable, electronics-applicable high-performance polymeric semiconductors.

Investigation of the Factors That Dictate the Preferred Orientation of Lexitropsins in the Minor Groove of DNA

Lexitropsins are small molecules that bind to the minor groove of DNA as antiparallel dimers in a specific orientation. These molecules have shown therapeutic potential in the treatment of several diseases; however, the development of these molecules to target particular genes requires revealing the factors that dictate their preferred orientation in the minor grooves, which to date have not been investigated. In this study, a distinct structure (thzC) was carefully designed as an analog of a well-characterized lexitropsin (thzA) to reveal the factors that dictate the preferred binding orientation. Comparative evaluations of the biophysical and molecular modeling results of both compounds showed that the position of the dimethylaminopropyl group and the orientation of the amide links of the ligand with respect to the 5′-3′-ends; dictate the preferred orientation of lexitropsins in the minor grooves. These findings could be useful in the design of novel lexitropsins to selectively target specific genes.
