Vanadium-based catalysts have shown activity and selectivity in ring-opening metathesis polymerization of strained cyclic olefins comparable to those of Ru, Mo, and W catalysts. However, the application of V alkylidenes in routine organic synthesis is limited. Here, we present the first example of ring-closing olefin metathesis catalyzed by well-defined V chloride alkylidene phosphine complexes. The developed catalysts exhibit tolerance to various functional groups, such as an ether, an ester, a tertiary amide, a tertiary amine, and a sulfonamide. The size and electron-donating properties of the imido group and the phosphine play a crucial role in the stability of active intermediates. Reactions with ethylene and olefins suggest that both beta-hydride elimination of the metallacyclobutene and bimolecular decomposition are responsible for catalyst degradation.

Chemistry, like all the natural sciences, Safety of tert-Butyl (4-bromobutyl)carbamate, begins with the direct observation of nature— in this case, of matter.164365-88-2, Name is tert-Butyl (4-bromobutyl)carbamate, SMILES is CC(C)(C)OC(=O)NCCCCBr, belongs to amides-buliding-blocks compound. In a document, author is Faig-Marti, Jordi, introduce the new discover.

Three-dimensional (3D) metal-semiconductor nanostructures as surface-enhanced Raman scattering (SERS) substrates were designed by in situ electrodeposition of gold nanoparticles (AuNPs) or in situ photodeposition of silver nanoparticles (AgNPs) on gallium nitride (GaN) nanoflowers (NFs) supports fabricated by metal-assisted photochemical etching of single crystalline GaN. 3D AuNPs/GaN NFs and AgNPs/GaN NFs substrates exhibit excellent enhancement effect for Rhodamine 6G (R6G) due to more hot spots in the same probing volume compared to 2D GaN based substrates. The enhancement factors of the AuNPs/GaN NFs and AgNPs/GaN NFs substrates are up to 2.1 x 10(7) and 5.9 x 10(7), respectively, and the corresponding detection limits of R6G are 10(-8) and 10(-10) M, respectively. Moreover, further study reveals both substrates have good reproducibility and long-term stability. The performance of the prepared substrates for biological application was demonstrated by the detection of bovine serum albumin (BSA). A series of characteristic bands of amides suggest BSA can be well adsorbed on the surface of the AuNPs/GaN NFs and AgNPs/GaN NFs substrates, which demonstrates our substrates have good biocompatibility and are promising candidates for SERS biosensors.

Herein, we describe an approach to cage metallasilsesquioxanes by self-assembly with 1,2-bis(diphenylphosphino)ethane as a key reactant. This approach allowed us to achieve a unique family of complexes that includes anionic tetra- and nonanuclear cage copper(II) sodium silsesquioxane and cationic copper(I) 1,2-bis(diphenylphosphino)ethane components. Additional representatives of this intriguing metallasilsesquioxane family (Cu9Na6 and Cu9Na3Cs3) were obtained through the replacement of the original ethanol-based reaction medium by DMSO. The fascinating structural peculiarities of all products were established by using XRD and topological studies. Initial tests for the application of the synthesized complexes as catalysts revealed their very high activity in the homogeneous oxidation of alkanes and alcohols to produce alkyl hydroperoxides, ketones, and amides.

The area of covalent inhibitors is gaining momentum due to recently introduced clinical drugs, but libraries of these compounds are scarce. Multicomponent reaction (MCR) chemistry is well known for its easy access to a very large and diverse chemical space. Here, we show that MCRs are highly suitable to generate libraries of electrophiles based on different scaffolds and three-dimensional shapes and highly compatible with multiple functional groups. According to the building block principle of MCR, acrylamide, acrylic acid ester, sulfurylfluoride, chloroacetic acid amide, nitrile, and alpha,beta-unsaturated sulfonamide warheads can be easily incorporated into many different scaffolds. We show examples of each electrophile on 10 different scaffolds on a preparative scale as well as in a high-throughput synthesis mode on a nanoscale to produce libraries of potential covalent binders in a resource-and time-saving manner. Our operational procedure is simple, mild, and step economical to facilitate future covalent library synthesis.

A naphthalimide-derived fluorescent sensor termed L2 was designed and synthesized. This sensor showed a highly selective, sensitive, and reversible turn-on response to Cd2+ over other metal ions in a wide pH range with a detection limit of 2.35 x 10(-10) M. The amide/di-2-picolylamine receptor binds Cd2+ in the imidic acid tautomeric form but other metal ions in the amide tautomeric form. Moreover, the sensor can be used to distinguish Cd2+ and Zn2+ with the naked eye. The Cd2+-binding mode and the recognition mechanism of the sensor were investigated using Job’s plot, H-1 NMR, HRMS, IR and DFT calculations. Furthermore, the sensor was successfully applied as the active component of indicator papers for on-site detection of Cd2+ in pure water and in fluorescence imaging of Cd2+ in HeLa cells.

The present study evaluates the effect of molecular mobility and molecular interactions in the physical stability of rivaroxaban (RIV) – soluplus (R) (SOL) amorphous solid dispersions (ASDs). Initially, the use of Adam-Gibbs approach revealed that RIV’s molecular mobility (below its glass transition temperature) is significantly reduced in the presence of SOL, while the use of ATR-FTIR spectroscopy showed the formation of hydrogen bonds (HBs) between the two ASD components, indicating that these two mechanisms can be considered as responsible for system’s physical stability. Contrary to previously published reports, the utilization of ATR-FTIR spectroscopy in the present study was able to clarify, for the first time, the type of intermolecular interactions formed within the examined ASD system, while the presence of a separate drug-rich amorphous phase (significantly increasing as the content of the drug increases) was also identified. Furthermore, in order to gain an insight into the intermolecular interactions responsible for drug’s amorphous phase separation, molecular dynamics (MD) simulation models were utilized as realistic representations of the actual systems. Analysis of the obtained trajectories showed that the formation of strong intermolecular HBs between RIV’s secondary amide proton and its three carbonyl oxygens (originating from the oxazolidone, oxomorpholin and carboxamide part of the drug molecule) as well as the significant reduction of the available HB acceptors in SOL due to copolymer’s chain shrinkage, were responsible for the formation of a separate drug-rich amorphous phase within the ASD.

We report a unique fluorescence sensor based on an axially chiral unnatural triazolyl aromatic amino acid scaffold ((Ar)TAA) for discrimination of methanol from ethanol via a switch on fluorescence response. All three sensors, the simple scaffold ((Ar)TAA), and the mono-(PyAm-(Ar)TAA) and bis-pyrenyl-(Py2Am-(Ar)TAA) amides, show similar sensitivity and detection limit ranging from 0.5-2.1 v/v% of ethanol. The solid films of these sensors are also found to be effective in sensing ethanol vapour via generation of a distinct and enhanced fluorescence signal. All our experimental results suggest the role of axial chirality of the hairpin-shaped scaffold in differential solvation guided H-bonding interaction and discriminating between ethanol and methanol with a switch-on fluorescence response.

Structural variations of the benzylphenoxyacetamide (BPA) molecular skeleton were explored as a viable starting point for designing new anti-glioblastoma drug candidates. Hand-to-hand computational evaluation, chemical modifications, and cell viability testing were performed to explore the importance of some of the structural properties in order to generate, retain, and improve desired anti-glioblastoma characteristics. It was demonstrated that several structural features are required to retain the anti-glioblastoma activity, including a carbonyl group of the benzophenone moiety, as well as 4′-chloro and 2,2-dimethy substituents. In addition, the structure of the amide moiety can be modified in such a way that desirable anti-glioblastoma and physical properties can be improved. Via these structural modifications, more than 50 compounds were prepared and tested for anti-glioblastoma activity. Four compounds were identified (HR28, HR32, HR37, and HR46) that in addition to HR40 (PP1) from our previous study, have been determined to have desirable physical and biological properties. These include high glioblastoma cytotoxicity at low mu M concentrations, improved water solubility, and the ability to penetrate the blood brain barrier (BBB), which indicate a potential for becoming a new class of anti-glioblastoma drugs.

Reversible covalent inhibitors have many clinical advantages over noncovalent or irreversible covalent drugs. However, apart from selecting a warhead, substantial efforts in design and synthesis are needed to optimize noncovalent interactions to improve target selective binding. Computational prediction of binding affinity for reversible covalent inhibitors presents a unique challenge since the binding process consists of multiple steps, which are not necessarily independent of each other. In this study, we lay out the relation between relative binding free energy and the overall reversible covalent binding affinity using a two-state binding model. To prove the concept, we employed free energy perturbation (FEP) coupled with lambda-exchange molecular dynamics method to calculate the binding free energy of a series of alpha-ketoamide analogues relative to a common warhead scaffold, in both noncovalent and covalent binding states, and for two highly homologous proteases, calpain-1 and calpain-2. We conclude that covalent binding state alone, in general, can be used to predict reversible covalent binding selectivity. However, exceptions may exist. Therefore, we also discuss the conditions under which the noncovalent binding step is no longer negligible and propose to combine the relative FEP calculations with a single QM/MM calculation of warhead to predict the binding affinity and binding kinetics. Our FEP calculations also revealed that covalent and noncovalent binding states of an inhibitor do not necessarily exhibit the same selectivity. Thus, investigating both binding states, as well as the kinetics will provide extremely useful information for optimizing reversible covalent inhibitors.
