Synthesis, biochemical evaluation and molecular modeling studies of nonpeptidic nitrile-based fluorinated compounds

Aim: Compounds that block enzyme activity can kill pathogens and help develop effective and safe drugs for Chagas disease and leishmaniasis. Materials & methods: A library of nonpeptidic nitrile-based compounds was synthesized and had their inhibitory affinity tested against cruzain, Leishmania mexicana cysteine protease B and cathepsin L. Isothermal titration calorimetry experiments and molecular simulations were performed for selected compounds to obtain thermodynamic fingerprints and identify main interactions and putative modes of binding with cruzain. Results: The derivatives provided increased affinity against all enzymes compared with the lead, and thermodynamic and computational studies showed improved thermodynamic properties and a possible different mode of binding. Conclusion: Our studies culminated in 1b, a compound 60-fold more potent in cruzain than its lead that also showed entropic and enthalpic contributions favorable to Gibbs binding energy.

Novel polyamide amidine anthraquinone platinum(II) complexes: cytotoxicity, cellular accumulation, and fluorescence distributions in 2D and 3D cell culture models

1- and 1,5-Aminoalkylamine substituted anthraquinones (AAQs, 1C3 and 1,5C3) were peptide coupled to 1-, 2-, and 3-pyrrole lexitropsins to generate compounds that incorporated both DNA minor groove and intercalating moieties. The corresponding platinum(II) amidine complexes were synthesized through a synthetically facile amine-to-platinum mediated nitrile ‘Click’ reaction. The precursors as well as the corresponding platinum(II) complexes were biologically evaluated in 2D monolayer cells and 3D tumour cell models. Despite having cellular accumulation levels that were up to five-fold lower than that of cisplatin, the platinum complexes had cytotoxicities that were only three-fold lower. Accumulation was lowest for the complexes with two or three pyrrole groups, but the latter was the most active of the complexes exceeding the activity of cisplatin in the MDA-MB-231 cell line. All compounds showed moderate to good penetration into spheroids of DLD-1 cells with the distributions being consistent with active uptake of the pyrrole containing complexes in regions of the spheroids starved of nutrients.

A Degradable and Self-Healable Vitrimer Based on Non-isocyanate Polyurethane

Developing degradable and self-healable elastomers composed of reusable resources is of great value but is rarely reported because of the undegradable molecular chains. Herein, we report a class of degradable and self-healable vitrimers based on non-isocyanate polyurethane elastomer. Such vitrimers are fabricated by copolymerizing bis(6-membered cyclic carbonate) and amino-terminated liquid nitrile rubber. The networks topologies can rearrange by transcarbonation exchange reactions between hydroxyl and carbonate groups at elevated temperatures; as such, vitrimers after reprocessing can recover 82.9-95.6% of initial tensile strength and 59-131% of initial storage modulus. Interestingly, the networks can be hydrolyzed and decarbonated in the strong acid solution to recover 75% of the pure di(trimethylolpropane) monomer. Additionally, the elastomer exhibits excellent self-healing efficiency (similar to 88%) and fracture strain (similar to 1,200%) by tuning the monomer feeding ratio. Therefore, this work provides a novel strategy to fabricate the sustainable elastomers with minimum environmental impact.

Functional Group Interconversion of Alkylidenemalononitriles to Primary Alcohols by a Cooperative Redox Operation

Functional group interconversions are essential chemical processes enabling synthesis. In this report, we describe a strategy to convert alkylidenemalononitriles into primary alcohols in one step. The reaction relies on a choreographed redox process involving alkylidene reduction, malononitrile oxidation, and acylcyanide reduction where molecular oxygen and NaBH(4)work cooperatively. The method was applied to a variety of carbon skeletons and was utilized to synthesize complex terpenoid architectures.

Understanding the Mechanism between Antisolvent Dripping and Additive Doping Strategies on the Passivation Effects in Perovskite Solar Cells

Perovskite polycrystalline films contain numerous intrinsic and interfacial defects ascribed to the solution preparation process, which are harmful to both the photovoltaic performance and the stability of perovskite solar cells (PVSCs). Although various passivators have been proved to be promising materials for passivating perovskite films, there is still a lack of deeper understanding of the effectiveness of the different passivation methods. Here, the mechanism between antisolvent dripping and additive doping strategies on the passivation effects in PVSCs is systematically investigated with a nonfullerene small molecule (F8IC). Such a passivated effect of F8IC is realized via coordination interactions between the carbonyl (C=O) and nitrile (C-N) groups of F8IC with Pb2+ ion of MAPbI(3). Interestingly, F8IC antisolvent dripping can effectively passivate the surface defects and thus inhibit the nonradiative charge recombination on the upper part of the perovskite layer, whereas F8IC additive doping significantly reduces the surface and bulk defects and produces a compact perovskite film with denser crystal grains, thus facilitating charge transmission and extraction. Therefore, these benefits are translated into significant improvements in the short-circuit current density (J(sc)) to 21.86 mA cm(-2) and a champion power conversion efficiency of 18.40%. The selection of an optimal passivation strategy should also be considered according to the energy level matching between the passivators and the perovskite. The large energetic disparity is unsuitable for additive doping, whereas it is expected in antisolvent dripping.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 123-06-8 is helpful to your research. SDS of cas: 123-06-8.

Palladium-catalyzed cascade reactions in aqueous media: synthesis and photophysical properties of pyrazino-fused quinazolinones

Heterocycle-fused quinazolinone derivatives have attracted great attention due to their diversified biological and optical activities. In this study, a novel one-pot palladium-catalyzed cascade C-C coupling/cyclization/aromatization of 2-(4-oxoquinazolin-3(4H)-yl)acetonitrile derivatives with arylboronic acids has been disclosed to synthesize 1,3-diaryl-6H-pyrazino[2,1-b]quinazolin-6-one in water. This protocol provides an efficient access to valuable pyrazino-fused quinazolinones in a green solvent (i.e., water) with yields ranging from moderate to excellent. Furthermore, the photophysical properties of these molecules were investigated. The resultant pyrazino-fused quinazolinones exhibit tunable fluorescence, and 3e displays the aggregation induced emission properties with a large Stokes shift. This study provides a useful approach to the development of pyrazino-fused quinazolinones, which have potential applications in chemistry, biology, and materials science.
