Non-viral gene therapy based on gene silencing with small interfering RNA (siRNA) has attracted great interest over recent years. Among various types of cationic complexation agents, amino acid-based surfactants have been recently explored for nucleic acid delivery due to their low toxicity and high biocompatibility. Monoolein (MO), in turn, has been used as helper lipid in liposomal systems due to its ability to form inverted nonbilayer structures that enhance fusogenicity, thus contributing to higher transfection efficiency. In this work, we focused on the development of nanovectors for siRNA delivery based on three gemini amino acid-based surfactants derived from serine – (12Ser)(2)N12, amine derivative; (12Ser)(2)COO12, ester derivative; and (12Ser)(2)CON12, amide derivative – individually combined with MO as helper lipid. The inclusion of MO in the cationic surfactant system influences the morphology and size of the mixed aggregates. Furthermore, the gemini surfactant:MO systems showed the ability to efficiently complex siRNA, forming stable lipoplexes, in some cases clearly depending on the MO content, without inducing significant levels of cytotoxicity. High levels of gene silencing were achieved in comparison with a commercially available standard indicating that these gemini:MO systems are promising candidates as lipofection vectors for RNA interference (RNAi)-based therapies.

An efficient method for preparation of secondary amides from primary amides and aldehydes using rhodium on carbon matrix as catalyst was developed. The method does not require any external hydrogen source and carbon monoxide is used as a reducing agent. The most active rhodium catalysts were characterized by BET, TEM and XPS techniques. Unexpectedly, it was found that heterogeneous rhodium on carbon matrix works as precatalyst for homogenous active species due to leaching of rhodium to the solution. Various secondary amides were synthesized and checked for antifungal activity. 4-Methoxy-N-(4-methoxybenzyl)benzamide demonstrated promising activity against Rhizoctonia Solani.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 71-00-1, Name is H-His-OH. In a document, author is Nazarova, A. A., introducing its new discovery. Category: amides-buliding-blocks.

Many cytoplasmic proteins contain a hydrophobic acyl chain, which facilitates protein binding to cell membranes. Hydrophobic interactions between the exposed acyl chain of the protein and hydrocarbon chains of lipids in the cell membrane are the driving force for this specific lipid- protein interaction. Recent studies point out that in addition to hydrophobic interactions the charge-charge and charge-dipole interactions between the polar head groups and basic amino acids contribute significantly to the binding process. Recoverin possesses a myristoyl chain at the N-terminus. In the presence of Ca2+ ions, the protein undergoes structural rearrangements, leading to the extrusion of the myristoyl chain, facilitating the protein binding to the membrane. In this work, we investigate the impact of interactions between the polar head group region of lipid molecules and recoverin which binds to the model membrane. The interaction with a planar lipid bilayer composed of phosphatidylcholine and cholesterol with myristoylated and nonmyristoylated recoverin is studied by in situ polarization modulation infrared reflection absorption spectroscopy. The binding of recoverin to the lipid bilayer depends on the transmembrane potential, indicating that the orientation of the permanent surface dipole in the supramolecular assembly of the lipid membrane influences the protein attachment to the membrane surface. Analysis of the amide I’ mode indicates that the orientation of recoverin bound to the lipid bilayer is independent of the presence of myristoyl chain in the protein and of the folding of the protein into the tense or relaxed state. In contrast, it changes as a function of the membrane potential. At positive transmembrane potentials, the alpha-helical fragments of recoverin are oriented predominantly parallel to the bilayer surface. This orientation facilitates the insertion of the acyl chain of the protein into the hydrophobic region of the bilayer. At negative transmembrane potentials, the a-helical fragments of recoverin change their orientation with respect to the membrane surface, which is followed by the removal of the myristoyl chain from the membrane.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 617-45-8, Name is DL-Aspartic Acid, molecular formula is C4H7NO4, belongs to amides-buliding-blocks compound, is a common compound. In a patnet, author is Aguilar-Galindo, Fernando, once mentioned the new application about 617-45-8, Safety of DL-Aspartic Acid.

Oligonucleotide (ON) conjugates are increasingly important tools for various molecular diagnostics, nanotechnological applications, and for the development of nucleic acid-based therapies. Multiple labeling of ONs can further equip ON-conjugates and provide improved or additional tailored properties. Typically, the preparation of ON multiconjugates involves additional synthetic steps and/or manipulations in post-ON assembly. This report describes the simplified methodology allowing for multiple labeling of ONs on a solid support and is compatible with phosphodiester as well as phosphorothioate (PS) ONs. The current approach utilizes two novel alkyne-and amino-functionalized linker phosphoramidites that can be readily synthesized from a common aminodiol intermediate in three steps. The combination of new linkers provides orthogonal functionalities, which allow for multiple attachments of similar or varied moieties. The linkers are incorporated into ONs during automated solid-phase ON synthesis, and the conjugation with functional entities is achieved by either amide bond formation or by copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC). The versatility of the approach is demonstrated by the synthesis of 5′-site ON multiconjugates with small molecules, peptides, and fatty acids as well as in the preparation of an internal peptide-ON conjugate.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 617-45-8. The above is the message from the blog manager. Safety of DL-Aspartic Acid.

Potential of zero charge (PZC) is essential in electrochemistry to understand physical and chemical phenomena at the interface between an electrode and a solution. A negative potential shift from the work function to the PZC has been experimentally observed in a metal/ionic liquid (IL) system, but the mechanism remains unclear and controversial. In this paper we provide valuable insight into the mechanism on the potential shift in the Au/IL (1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide: [BMIM][TFSA]) system using a computational approach combining classical molecular dynamics simulations and first-principles calculations. By separately estimating some contributions to the potential shift, the shift is calculated in an easy-to-understand manner. The resultant PZC is shown to be in good agreement with the experimental one. Among the contributions, the electron redistribution at the Au/IL interface is found to provide the largest negative potential change. This indicates that the redistribution plays a crucial role in determining the potential shift of the Au electrode immersed in the IL. Detailed analyses suggest that the redistribution corresponds to the electron transfer not only from the anionic TFSA but also from the cationic BMIM molecules to the Au electrode surface. This unique observation is understood to originate from the interfacial structure where the IL molecules are in very close proximity to the electrode surface via dispersion interaction.

Synthetic cross-linked collagen-related peptide (CRP-XL) is a glycoprotein VI (GPVI) receptor activator for platelet activation. This triple helical peptide, widely used in platelet function tests, is synthesized and cross-linked through cysteine residues at its N-terminus and C-terminus. Currently, there is only one laboratory, which is capable to produce this valuable peptide for clinical applications. In an attempt to provide a standardized alternative for CRP-XL, we developed a synthetic triple helical collagen peptide (STH-CP) with the same primary sequence as CRP-XL (GPC-(GPO) (10) -GPCG-amide) (3) , which was both on the C-terminus and on the N-terminus fixed on a scaffold with a binding side for each of the three peptides. The performance of STH-CP on platelet function was studied using flow cytometry and compared with CRP-XL. We found that platelet activation pattern in response to STH-CP and CRP-XL is similar, although the STH-CP requires sixfold higher concentrations to activate platelets to the same state. The intra-assay percent coefficient of variation of STH-CP and CRP-XL were both < 5% and the interindividual variation measured in 118 individuals for both peptides was around 23 and 21% for alpha IIb beta 3 activation and P-selectin expression, respectively. The STH-CP in ready-to-use reaction mix has lower variation than CRP-XL over 1-year storage. In reference values and seasonal variation study, the platelet activation response showed a strong correlation between STH-CP and CRP-XL. Our findings show that this new STH-CP is a stable and potent platelet GPVI agonist which can induce the same reproducible platelet activation as CRP-XL and that STH-CP can be considered as a good alternative for CRP-XL. Application of 14433-76-2, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about 14433-76-2 is helpful to your research.

The mechanical stability of conventional single-channel capillary fibres can be improved in a multi-channel geometry, which has previously found application in ultrafiltration. In this work, multi-channel polyethersulfone (PES) capillary membranes comprising seven feed channels were successfully fabricated in an enhanced steam-dry-wet spinning process and coated on the inner surface with a thin polyamide (PA) layer via interfacial polymerization (IP). The coating procedure consisted of impregnating the support multi-channel capillary membranes (MCM) with an aqueous piperazine solution, flushing with nitrogen gas to remove excess droplets, and pumping an organic trimesoylchloride solution through the channels. Insights into the interfacial polymerization process were gained through the investigation of various parameters, including monomer ratio, contact time, and drying time. Membranes were characterised via scanning electron microscopy (SEM), atomic force microscopy (AFM), and filtration experiments. The optimisation of both the PES support membrane and IP process parameters allowed for the fabrication of composite MCM with an MgSO4 rejection of 91.4% and a solute flux of 68.8 L m(-2) h(-1) at an applied pressure of 3 bar. The fabricated composite MCM demonstrates that a favourable multi-channel arrangement can be upgraded with a PA layer for application in low-pressure nanofiltration.
