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.

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.

The combination of multistage mass spectrometry experiments employing the distonic radical approach together with DFT calculations are used to examine addition of the N-methyl-pyridinium-4-yl radical cation (gamma-NMP) to iso(thio)cyanates in the gas-phase. The type of products formed depend on the nature of the iso(thio)cyanate: (1) hydrogen atom abstraction occurs for alkyl isocyanates; (2) aryl isocyanates undergo radical-ipso substitution; (3) radical attack occurs at the C=C bond of allyl isocyanate; (4) radical attack occurs at the C=S bond of isothiocyanates to generate S adducts of gamma-NMP and isonitriles. DFT calculations provide insight into the reactivity differences of these heterocumulenes towards the electrophilic C-centered gamma-distonic radical cations. Translation of these gas phase results to the solution phase were hampered by dominating radical recombination reactions which appear to be favoured over the radical-iso(thio)cyanate reactions.

Struvite crystallization has been so far proved to be a potential technology for nitrogen and phosphorus recovery from nutrient-rich wastewater. However, humic acid (HA) among organic matters in nutrient-rich wastewaters would inevitably exert an adverse impact on the crystallization. Therefore, in the present study, we innovatively propose a process monitor chart to accurately differentiate and quantify the nucleation and crystal growth of struvite crystallization by means of constant composition technique, thereby probing the effect of HA on the nucleation and growth kinetics of struvite. Moreover, the mechanism underlying the interaction between HA and struvite crystals was also explored by FTIR and XPS analysis. The results indicated that HA not only significantly prolonged the induction time, but also decreased the growth rate of struvite crystals. This can be explained by the fact that HA is prone to complex with the reactant, and its subsequent adsorption on the surface of struvite crystals performs during the crystallization process. Consequently, the crystal morphology initially varied from rod-like shape to trapezoidal prism, and ultimately to triangular prism, as HA concentration gradually increased from 0 to 100 mg/L. Interestingly, the interaction between HA and struvite crystals is likely to be triggered by the formation of amide, HA-Mg2+ complex and phosphate ester on the crystal surface. These findings herein put forward an innovate method to elucidate the inhibitory effect of organic matter on the nucleation and growth kinetics of struvite, which can provide a theoretical basis for understanding the interference of organic pollutants with struvite crystallization.

On the basis of the data of infrared spectroscopy with synchrotron radiation, the secondary structure of proteins of the dentinal and gingival fluids during the development of cariosity in deep dentin tissues is studied. It is shown that the change in the shape of the profile of the amide I band in the region of 1700-1605 cm(-1) is associated both with a change in the ratio of the integrated absorption intensities of the alpha-helix and beta-sheet secondary structures and with the position of the beta-coil and beta-sheet components in the spectrum. It is established that the alpha-helix/beta-sheet ratio for both dentinal and gingival fluids is below the threshold level, at which significant changes in the secondary structure of proteins of biological fluids are observed, unequivocally indicating the development of pathology in hard dental tissues. The features that we discovered in the profile of the amide I band of biological fluids of the oral cavity, together with the spectral markers of the development of cariosity in dentin, are reliable spectroscopic signatures of the pathology and can be detected using the gingival fluid.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 600-21-5. COA of Formula: https://www.ambeed.com/products/600-21-5.html.

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.

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 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.

Purpose: To achieve the combination therapy of acute myocardial ischemia, arginyl-glycyl-aspartic acid (RGD) conjugated lipid was synthesized and RGD modified, salvianolic acid B (Sal B) and panax notoginsenoside (PNS) co-loaded lipid-polymer hybrid nanoparticles (RGD-S/P-LPNs) was fabricated an evaluated. Methods: RGD was conjugated to distearoyl phosphatidylethanolamine-polyethylene glycol (DSPE-PEG-NH2) through amide linkage. Lipid-polymer hybrid nanoparticles (LPNs) were fabricated by nanoprecipitation method. RGD-S/P-LPNs was characterized in terms of morphology, size, charge, drug loading, entrapment, stability, drug release and cytotoxicity in vitro. Cardiac distribution, pharmacokinetics study and infarct therapy effect were evaluated in vivo. Results: The LPNs are generally spherical in shape with uniform size distribution, have sizes of 100-200 nm and zeta potentials range from -30.7 similar to -39.8. In vitro release behaviors of drugs loaded LPNs are in a sustained release manner, which does not exhibit obviously cytotoxicity against H9c2 cardiomyocytes. RGD-S/P-LPNs group shows the most significant cardiac distribution and infarct therapy effect in vivo. Conclusion: The results illustrated that RGD modified dual drugs co-loaded LPNs are stable, sustained release carriers. Cardiac distribution, pharmacokinetics, and infarct therapy effect results suggested that the RGD-S/P-LPNs could improve the in vivo therapeutic efficacy of the double drugs.
