Abstract (sommario):

AbstractThe CdSe quantum dots (QDs) with bidentate ligands: a-diimine (NN) and dihydrolipoic acid (DHLA) were synthesized and characterized by UV-Vis, particle size and capillary electrophoretic techniques. Two systems were analyzed: CdSe with one ligand (CdSe/ligand) and CdSe with two different ligands (CdSe//ligand1/ligand2), where ligand = α-diimine or DHLA. Hydrodynamic features of functionalized QDs were characterized by zone capillary electrophoretic (CZE), and particle size techniques and these methods were consistent. It was established that CZE, micellar (MEKC) and microemulsion (MEEK

Abstract (sommario):

The carbonyl-ene reaction is one of the most well-known reactions for C–C bond formation. Based on frontier molecular orbitals (FMO), carbonyl-ene reactions occur between the highest occupied molecular orbital (HOMO) of the ene compound bearing an active hydrogen atom at the allylic center and the lowest unoccupied molecular orbital (LUMO) of the electron-deficient enophile, which is a carbonyl compound. A high activation barrier enforces the concerted ene reaction rather than a Diels–Alder reaction at high temperature. Employing a catalytic system can eliminate defects in the ene reaction, an

Abstract (sommario):

Weakly interacting ligands including three Gemini surfactants, didodecyldimethylammonium bromide (DDAB), and amines (RNH2, R2NH, and R3N) were used to prepare Au nanoparticles (NPs). Aqueous Au NPs capped with DDAB and Gemini surfactants showed similar sizes (3–4 nm), whereas toluene-based NPs stabilized with DDAB, amines, and their mixtures range from 2.5 to 9.3 nm. Ligand effect on Au–Pd NP structure was also studied with EXAFS. These findings were consistently accounted for by considering the ligand’s electronic/steric effects and mixed ligands coadsorption, and suggest useful ways to contr

Abstract (sommario):

The complexation behavior of lanthanide(III) ions with terephthalic acid (1,4-benzene-dicarboxylic acid) in 0.01 M KNO3 aqueous solutions was studied across a broad pH range and at two metal-to-ligand ratios using potentiometric titration combined with photoluminescence spectroscopy. Chemometric analysis of titration curves enabled the determination of relative molar fractions, stability constants, and probable stoichiometry of the formed complexes. In solutions with a 1:2 metal-to-ligand ratio, bis-complexes (two terephthalate ligands per lanthanide ion) predominated, while ligand-rich condit

Abstract (sommario):

The equilibrium distribution of small molecules (ligands) between binding agents in heterogeneous media is an important property that determines their activity. Heterogeneous systems containing proteins and lipid membranes are particularly relevant due to their prevalence in biological systems, and their importance to ligand distribution, which, in turn, is crucial to ligand’s availability and biological activity. In this work, we review several approaches and formalisms for the analysis of the equilibrium distribution of ligands in the presence of proteins, lipid membranes, or both. Special a

Abstract (sommario):

It is highly desirable, while still challenging, to obtain noble metal nanocrystals with custom capping ligands, because their colloidal synthesis relies on specific capping ligands for the shape control while conventional ligand exchange processes suffer from “the strong replaces the weak” limitation, which greatly hinders their applications. Herein, we report a general and effective ligand exchange approach that can replace the native capping ligands of noble metal nanocrystals with virtually any type of ligands, producing flexibly tailored surface properties. The key is to use diethylamine

Abstract Influenza is a highly communicative viral pathogen that infects 9–35 million individuals and results in 12,000–56,000 deaths in the US annually. For the most commonly used seasonal influenza vaccine, historical efficacy rates range from 10–60% thus improvements to the current vaccine are needed. We identified a novel series of synthetic TLR7/8 ligands that improve influenza vaccine efficacy when used alone or in combination with our synthetic TLR4 ligand. In human PBMCs, TLR7/8 ligands elicited secretion of the inflammatory cytokines TNFα, IL-6, and IL-1β as well as the Th1-polarizing

Designing potent and subtype-selective ligands with therapeutic value requires knowledge about how ligands interact with their binding sites. y-Aminobutyric acid (GABA) is the predominant inhibitory neurotransmitter in the mammalian CNS and its binding modes at GABA r

Nuclear receptors are ligand activated transcription factors, where upon binding with small molecule ligands, these proteins are involved in the regulation of gene expression. To date there are approximately 48 human nuclear receptors known, involved in multiple biological and cellular processes, ranging from differentiation to maintenance of homeostasis. Due to their critical role in transcriptional regulation, these receptors are implicated in several diseases. Currently, 13% of prescribed drugs in the market are NR ligands for diseases such as cancer, diabetes and osteoporosis. In addition

The results of our study showcase the efficacy of PoLiGenX in ligand design.

Cells communicate with one another through a huge variety of extracellular soluble signaling molecules. A common method in biology to investigate the signaling pathways is to inactivate the gene coding the interested ligand or receptor from cells using modern DNA technology, known as gene knockout. Even though very effective, however, gene knockout is a time-consuming and cost-prohibitive process and requires huge amount of efforts to conduct. Here we present a simple method to probe the extracellular signaling pathways through engineering a semi-permeable barrier between two cell populations.

Abstract (sommario):

Abstract Recently, there has been an increasing interest in measuring the interaction forces between cell adhesion receptors and their ligands [1–3]. These molecules are either anchored on the membrane of a cell or coated on the surface of a substratum. The two surfaces are joined together as a result of the formation of non-covalent bonds between the receptors and ligands. The forces are measured when the two surfaces are separated. In a theoretical paper published nineteen years ago, George Bell estimated the force required to break a receptor-ligand bond and that required to uproot the rece

Abstract (sommario):

Detailed kinetic studies of the urokinase catalysed conversion of Lys-77- and Val-440-plasminogens in the presence and absence of ligands binding to the AH-site of the plasminogens shows that the effects of such ligand-binding correspond with a model of the activation reaction in which the effective Km and kc decreases, but kc/Km increases when the ligands bind. Apparently plasminogen with a free AH-site is a less specific substrate for urokinase, than is plasminogen with an AH-site-bound ligand.The AH-site is a weak lysine binding site of plasminogen located in the mini plasminogen part (Val-

Abstract (sommario):

In this work, using the in-silico experiment modeling method, the receptor and its ligands were docked in order to obtain the data necessary to study the possibility of using machine learning and hard intermolecular docking methods to predict potential ligands for various receptors. The protein TRPM8 was chosen, which is a member of the TRP superfamily of proteins and its classic agonist menthol as a ligand. It is known that menthol is able to bind to tyrosine 745 of the B chain. To carry out all the manipulations, we used the Autodock software and a special set of graphic tools designed to wo

Abstract (sommario):

To facilitate analysis of nanoscale heat transfer in nanoparticle systems the thermal properties of ligand layers must be understood. To this end, we use an optical pump-probe technique to study the thermal transport across ligands on gold nanorods and into the solvent. We find that varying properties of the ligand can have large impacts on the thermal decay of a nanorod after exposure to a laser pulse. By raising the concentration of free CTAB from 1 mM and 10 mM in solutions, the CTAB layer’s effective thermal interface conductance increases three fold. The transition occurs near the CTAB cr
