A series of highly dispersed cobalt-based catalysts on N-doped ordered porous carbon (Co-NOPC) were synthesized using the sacrificiallate method. MCM-41, ZSM-5 and SBA-15 were employed as hard templates with 2,2′-bipyridine as the ligand. The physical and

Two catalysts, based on gold on zirconia and prepared in the same way, except for the different thermal treatment in air after the addition of gold (0.4% wt), show a quite different behavior in furfural oxidative esterification, particularly in the select

It is an attractive and challenging topic to endow non-noble metal catalysts with high efficiency via a nitrogen-doping approach. In this study, a nitrogen-doped carbon catalyst with high nitrogen content encapsulating cobalt NPs (CoOx@N-C(g))

The tunable transformation of renewable furfural with aliphatic alcohols in the presence of O2 is developed. Based on a nano Au catalyst and potassium carbonate, a 91.8% yield of methyl 2-furoate with 98.7% selectivity is obtained via the oxidative esterification in a furfural-methanol-O2 system; while a 91.4% yield of 3-(furan-2-yl-)-2-methylacrylaldehyde with 97.2% selectivity is attained via the oxidative condensation in a furfural-n-propanol-O2 system. This journal is

Visible irradiation of a methanolic solution of furfural containing dilute aqueous H2O2 and PF6 (1: R=H, Cl or CH3) as catalyst yields methyl 2-furoate quantitatively.After photodecomplexation, the inorganic FeII,III catalyst can b

The direct esterification of alcohols with non-noble metal-based catalytic systems faces great challenges. Here, we report a new chrome-based catalyst stabilized by a single pentaerythritol decorated Anderson-type polyoxometalate, [N(C4H9)4]3[CrMo6O18(OH)3C{(OCH2)3CH2OH}], which can realize the efficient transformation from alcohols to esters by H2O2oxidation in good yields and high selectivity without extra organic ligands. A variety of alcohols with different functionalities including some natural products and pharmaceutical intermediates are tolerated in this system. The chrome-based catalyst can be recycled several times and still keep the original configuration and catalytic activity. We also propose a reasonable catalytic mechanism and prove the potential for industrial applications.

The expression of β-lactamases, especially metallo-β-lactamases (MβLs) in bacteria is one of the main causes of drug resistance. In this work, an effective N-acylhydrazone scaffold as MβL inhibitor was constructed and characterized. The biological activity assays indicated that the synthesized N-acylhydrazones 1–11 preferentially inhibited MβL NDM-1, and 1 was found to be the most effective inhibitor with an IC50 of 1.2 μM. Analysis of IC50 data revealed a structure–activity relationship, which is that the pyridine and hydroxylbenzene substituents at 2-position improved inhibition of the compounds on NDM-1. ITC and enzyme kinetics assays suggested that it reversibly and competitively inhibited NDM-1 (Ki = 0.29 ± 0.05 μM). The synthesized N-acylhydrazones showed synergistic antibacterial activities with meropenem, reduced 4–16-fold MIC of meropenem on NDM-1- producing E. coli BL21 (DE3), while 1 restored 4-fold activity of meropenem on K. pneumonia expressing NDM-1 (NDM-K. pneumoniae). The mice experiments suggested that 1 combined meropenem to fight against NDM-K. pneumoniae infection in the spleen and liver. Cytotoxicity assays showed that 1 and 2 have low cytotoxicity. This study offered a new framework for the development of NDM-1 inhibitors.
