Polydiacetylene vesicles functionalized with N-heterocyclic ligands for metal cation binding

Self assembled poly diacetylene (PDA) based blue vesicles LS-Terpy, LS-DPA, LS-DP and LS-DEA with metal chelating sites have been prepared and characterized. Their response to the presence of metal cations in buffered aqueous solution has been investigated by monitoring changes of colour, UV-Vis absorption and emission. The addition of zinc, manganese, cadmium, mercury or silver salts to solutions of the vesicles induces a colour change from blue to red observable by the naked eye, while the addition of other metal salts, containing ions like Li+, Na+, K+, Mg 2+, Ca2+, Cr2+, Ni2+, Fe 2+, Co2+, Cu2+ or Pb2+, failed to show any changes. The metal ion coordination selectivity of the ligands is slightly different for the vesicle surface immobilized ligands compared to the reported metal cation binding of the corresponding ligands in solution, which may be due to the special environment at the lipid-solution interface. The vesicles aggregate upon metal ion coordination to the embedded ligands as shown by dynamic light scattering (DLS) particle size analysis. The functionalized PDA vesicles retain their response to the presence of aqueous solutions of metal ions if immobilized in transparent polyvinyl alcohol films or on paper.

A novel series of imidazoisoindoles were identified as potent indoleamine-2,3-dioxygenase (IDO) inhibitors. Lead optimization toward improving potency and eliminating CYP inhibition resulted in the discovery of lead compound 25, a highly potent IDO inhibitor with favorable pharmacokinetic properties. In the MC38 xenograft model in hPD-1 transgenic mice, 25 in combination with the anti-PD-1 monoclonal antibody (SHR-1210) achieved a synergistic antitumor effect superior to each single agent.

Synthesis of a tetrapyrazinoporphyrazine-based fluorescent sensor for detection of Cu2+ ion

In this study, a novel tetrapyrazinoporphyrazine-based fluorescent sensor for Cu2+ ion was synthesized and fully characterized by 1H NMR, MALDI-TOF MS, and elemental analysis. A tetrapyrazinoporphyrazine substituent was used as the reporting group and a 2,2?-dipyridylamine moiety was employed as the recognition group. The effects of various metal ions on the absorption and emission spectra of the designed molecule were investigated, demonstrating that this compound shows selectivity and sensitivity toward the Cu2+ ion. Upon addition of Cu2+ ion, a fluorescent intensity of the tetrapyrazinoporphyrazine-based sensor decreased gradually at 655?nm. To confirm a selective binding ability of 2,2?-dipyridylamine moiety toward Cu2+ ion, a comparative study was performed using tetrapyrazinoporphyrazine derivative with bromine instead of 2,2?-dipyridylamine moiety. Furthermore, association constant and detection limit value of the synthesized compound toward Cu2+ ion were derived from a repetitive titration experiment. Also, a reversibility of the prepared sensor was confirmed through additional test using compound and ethylenediaminetetraacetic acid.

Foundational techniques for catalyst design in the upgrading of biomass-derived multifunctional molecules

The production of fuels and chemicals from renewable lignocellulosic biomass resources has been a major research focus in the last few decades. The most efficient method for synthesizing value-added chemical products from sustainable feedstocks is direct catalytic conversion, however, the multifunctional and highly oxygenated biomass-derived substrates are significantly different from petroleum-based feedstocks. Thus, systematic development of new catalytic materials is required to take advantage of the only substantial source of renewable carbon. In this review, we discuss the foundational methodologies that enable rational catalyst design through the investigation of surface-adsorbate interactions and the elucidation of descriptors for selectivity control. Molecular spectroscopies, efficient and predictive computational modeling, rigorous kinetic investigations, and highly controlled materials synthesis have generated fundamental insights leading to general catalyst design principles in biomass upgrading processes. The application of each technique in biomass research is discussed in the context of several case studies, with a focus on the unique insights available from each technique. Moreover, the interplay among multiple techniques, particularly between experimental and computational methods, is also highlighted. Despite the impressive progress made in the biomass field, major roadblocks still exist due to the complexity in the composition and structure of both substrates and catalysts. We share our perspectives regarding future needs in selective catalytic conversions of multifunctional substrates and methods for accelerating catalyst development.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2081-44-9, help many people in the next few years., Electric Literature of 2081-44-9

Imidazopyridinium and pyridopyrimidium bromides: Synthesis and hydrolysis

The reactions of symmetrical and unsymmetrical 2,2?-dipyridylamines with 1,2-dibromoethane and 1,3-dibromopropane give imidazopyridinium and pyridopyrimidium bromides, respectively. These acetone/CH2Cl2 -insoluble, highly fluorescent quaternary ammonium salts undergo addition/ring opening upon treatment with methanolic KOH to give pyridin-2-one derivatives. A sequential N,N-dialkylation/ring-opening hydrolysis/N,N-dialkylation/ring-opening hydrolysis strategy was developed for the construction of unsymmetrical bis(pyridin-2-ones).

Total Synthesis of a Densely Functionalized Plesiomonas shigelloides Serotype 51 Aminoglycoside Trisaccharide Antigen

Plesiomonas shigelloides, a pathogen responsible for frequent outbreaks of severe travelers’ diarrhea, causes grave extraintestinal infections. Sepsis and meningitis due to P. shigelloides are associated with a high mortality rate as antibiotic resistance increases and vaccines are not available. Carbohydrate antigens expressed by pathogens are often structurally unique and are targets for developing vaccines and diagnostics. Here, we report a total synthesis of the highly functionalized trisaccharide repeating unit 2 from P. shigelloides serotype 51 from three monosaccharides. A judicious choice of building blocks and reaction conditions allowed for the four amino groups adorning the sugar rings to be installed with two N-acetyl (Ac) groups, rare acetamidino (Am), and d-3-hydroxybutyryl (Hb) groups. The strategy for the differentiation of amino groups in trisaccharide 2 will serve well for the syntheses of other complex glycans.
