Vergelli, Claudia;Khlebnikov, Andrei I.;Crocetti, Letizia;Guerrini, Gabriella;Cantini, Niccolo;Kirpotina, Liliya N.;Schepetkin, Igor A.;Cilibrizzi, Agostino;Quinn, Mark T.;Rossi, Patrizia;Paoli, Paola;Giovannoni, Maria Paola research published 《 Synthesis, biological evaluation, molecular modeling, and structural analysis of new pyrazole and pyrazolone derivatives as N-formyl peptide receptors agonists》, the research content is summarized as follows. N-formyl peptide receptors (FPR1, FPR2, and FPR3) play key roles in the regulation of inflammatory processes, and recently, it was demonstrated that FPR1 and FPR2 have a dual role in the progression/suppression of some cancers. Therefore, FPRs represent an important therapeutic target for the treatment of both cancer and inflammatory diseases. Previously, we identified selective or mixed FPR agonists with pyridazinone or pyridinone scaffolds showing a common 4-(bromophenyl)acetamide fragment, which was essential for activity. We report here new pyrazole and pyrazolone derivatives as restricted analogs of the above 6-membered compounds, all exhibiting the same 4-bromophenylacetamide side chain. Most new products had low or absent FPR agonist activity, suggesting that the pyrazole nucleus was not appropriate for FPR agonists. This hypothesis was confirmed by mol. modeling studies, which highlighted that the five-membered scaffold was responsible for a worse arrangement of the mols. in the receptor binding site.

Venkatesan, Kumar;Haider, Nazima;Yusuf, Mohammad;Hussain, Afzal;Afzal, Obaid;Yasmin, Sabina;Altamimi, Abdulmalik S. A. research published 《 Water/transcutol/lecithin/M-812 green cationic nanoemulsion to treat oxytetracycline contaminated aqueous bulk solution》, the research content is summarized as follows. Oxytetracycline (OXT) has been recognized as the most common veterinary medicine discharge responsible to cause water contamination and subsequent health issues in aquatic animals and human health. The study addressed the use of cationic (water/transcutol/lecithin/M-812) green nanoemulsion as an efficient, effective, and cost effective approach. Components were selected based on the drug solubility and HSP (Hansen solubility parameter) software (HSPiP software). Several batches of green cationic nanoemulsions (GNE1-GNE5) were tailored using medium chain triglyceride, transcutol, and lecithin as dictated in pseudoternary phase diagrams followed by thermodn. stability study. These were characterized for globular size and size distribution, zeta potential, refractive index (RI), viscosity, and pH. Moreover, removal efficiency (%) and the impact of exposure time (5, 10, and 20 min) on removal efficiency were investigated. Finally, the treated water was assessed to ensure free from OXT using SEM-EDX (SEM- energy dispersive X-ray anal. mode) and ICP-OES (inductively coupled plasma-optical emission spectrometry). Result showed that removal efficiency was significantly dependent upon (a) globular size, (b) water content, (c) oil content, and (d) viscosity. However, the exposure time for emulsification had no considerable impact. The most optimized cationic GNE5 was characterized with low size (38 nm), optimal zeta potential (+26 mV), low viscosity (316.5 cP), and the highest removal efficiency (90.3% at 20 min) as compared to resp. anionic nanoemulsion. SEM-EDX and ICP-OES results corroborated the absence of OXT in the treated water. Hence, this approach is promising to decontaminate anionic OXT present in wastewater using cationic GNE5 (to get OXT loaded ONE5 after dispersion).

Vastl, Julian;Kartika, Rendy;Park, Kichul;Cho, Art E.;Spiegel, David A. research published 《 Peptidines: glycine-amidine-based oligomers for solution- and solid-phase synthesis》, the research content is summarized as follows. Efforts to emulate biol. oligomers have given rise to a host of useful technologies, ranging from solid-phase peptide and nucleic acid synthesis to various peptidomimetic platforms. Herein, the authors introduce a novel class of peptide-like oligomers called “peptidines” wherein each carbonyl O-atom within poly-N-alkyl glycine oligomers is replaced with a functionalized N-atom. Compared to peptoids or peptides, the presence of this amidine N-substituent in peptidines effectively doubles the number of diversification sites per monomeric unit, and can decrease their overall conformational flexibility. The authors have developed iterative solution- and solid-phase protocols for the straightforward assembly of peptidines containing diverse backbone and amidine substituents, derived from readily available primary and secondary amines. The authors have also performed crystallog. and computational studies, which demonstrate a strong preference for the trans (E) amidine geometry. Given their straightforward synthetic preparation and high functional group d., peptidines have the potential to serve as useful tools for library generation, peptide mimicry, and the identification of biol. active small mols.

Vasdev, Nupur;Handa, Mayank;Kesharwani, Prashant;Shukla, Rahul research published 《 Rosemary oil low energy nanoemulsion: optimization, μrheology, in silico, in vitro, and ex vivo characterization》, the research content is summarized as follows. Acetylcholine imbalance in the human brain causes dementia-related symptoms of Alzheimer′s disease. Acetylcholinesterase (AChE) inhibitors prevent the lysis of acetylcholine in the brain and prevent dementia. Therefore, the present study aims to investigate the in silico and in vitro AChE potential of rosemary oil and then formulate it into nanoemulsion as an adjuvant with co-administration of Donepezil (Dz) with a thought for futuristic target for Alzheimer′s diseases via the intranasal route. The aim for preparing this formulation was to add the AChE inhibition effect of the rosemary oil to the effect that acts as an additive effect along with Dz. The docking score of rosemary oil components on human cholinesterase 1GQR protein was found to be >-5 kcal/mol. In vitro AChE activity of rosemary oil confirms the prominent IC50 of oil at 0.001 μL/min. Nanoemulsion was prepared by low energy emulsification technique using Tween 80 as surfactant and ethanol or diethylene glycol monoethyl ether as cosurfactant. Droplet size, polydisperity index, and zeta potential of stable nanoemulsion was ∼16 nm, 0.1, and -6.05 mV for stable batch. High-resolution transmission electron microscopy microscopic studies depicted the spherical shape of the droplet. Micro rheol. investigation of nanoemulsion clearly attributes to gel-sol-gel behavior of formulated nanoemulsion. Thermal evaluation of nanoemulsion depicts the phase transition behavior of ethanol-based nanoemulsion at 60 °C. Ex vivo nasal ciliotoxicity and permeation studies of formulation establish the safety of ethanol-based rosemary oil-loaded nanoemulsion and permeation mechanism of Dz from the nanoemulsion. In vitro permeation studies showed more drug penetration from the nanoemulsion as compared to the plain drug. The prepared nanoemulsion was found to be stable for 3 mo at 4, 25, and 45 °C of storage. This low energy preparation method can be advantageous for the preparation of scalable nanoemulsion and can be a futuristic therapeutic for Alzheimer′s disease.

Tyrikos-Ergas, Theodore;Gim, Soeun;Huang, Jhih-Yi;Pinzon Martin, Sandra;Varon Silva, Daniel;Seeberger, Peter H.;Delbianco, Martina research published 《 Synthetic phosphoethanolamine-modified oligosaccharides reveal the importance of glycan length and substitution in biofilm-inspired assemblies》, the research content is summarized as follows. Bacterial biofilm matrixes are nanocomposites of proteins and polysaccharides with remarkable mech. properties. Efforts understanding and tuning the protein component have been extensive, whereas the polysaccharide part remained mostly overlooked. The discovery of phosphoethanolamine (pEtN) modified cellulose in E. coli biofilms revealed that polysaccharide functionalization alters the biofilm properties. To date, the pattern of pEtN cellulose and its mode of interactions with proteins remains elusive. Herein, we report a model system based on synthetic epitomes to explore the role of pEtN in biofilm-inspired assemblies. Nine pEtN-modified oligosaccharides were synthesized with full control over the length, degree and pattern of pEtN substitution. The oligomers were co-assembled with a representative peptide, triggering the formation of fibers in a length dependent manner. We discovered that the pEtN pattern modulates the adhesion of biofilm-inspired matrixes, while the peptide component controls its stiffness. Unnatural oligosaccharides tune or disrupt the assembly morphol., revealing interesting targets for polysaccharide engineering to develop tunable bio-inspired materials.

Trzepizur, Damian;Brodzka, Anna;Koszelewski, Dominik;Wilk, Monika;Ostaszewski, Ryszard research published 《 Selective Palladium-Catalyzed α,β-Homodiarylation of Vinyl Esters in Aqueous Medium》, the research content is summarized as follows. A palladium-catalyzed 1,2-diarylation of vinyl esters RC(O)OCH=CH₂ (R = Me, Ph, CH₂Cl, etc.) with arylboronic acids R¹B(OH)₂ (R¹ = Ph, 3,4-dimethoxyphenyl, 2-bromophenyl, etc.) in water has been developed. This newly elaborated protocol features a good functional group tolerance and provides one-step access to 1,2-diarylethanol derivatives R¹CH₂CH(R¹)OC(O)R under mild reaction conditions. The presented reaction can be carried out in the water at ambient temperature without the addition of any ligands, making this procedure environmentally benign. The transformation occurs within a single catalytic cycle and is feasible due to the modification of transition metal catalytic activity through the influence of π-acceptor olefin (benzoquinone) as well as water as a medium. Moreover, this protocol allows to generate entire compound libraries (highly profitable in medicinal chem.) and utilizes sustainable arylboronic acids as coupling partners under mild conditions. It is also noted that the structure of boron moiety has a great impact on the reaction selectivity, the usage of sterically hindered esters of arylboronic acids influence the reaction course towards stilbenes.
