Bronsted acidic ionic liquids (BAILs) have been used as catalyst and solvent in organic synthesis, due to their negligible volatility, remarkable solubility, good catalytic activity, and easily structurally tunable properties. In the present study, we have investigated the catalytic efficiency of economically viable ionic liquids bearing different cations pyridinium ([PyH](+) and triethylammonium [TEAH](+)) for the esterification of aromatic acid with various aliphatic alcohols and crossed aldol condensation of aromatic aldehydes with cyclohexanone under ambient condition. We also examined the effect of various process parameters on the yield of aromatic esters and alpha,alpha’-bis(arylidene)cycloalkanones.

With the infection rate of Bordetella pertussis at a 60-year high, there is an urgent need for new anti-pertussis vaccines. The lipopolysaccharide (LPS) of B. pertussis is an attractive antigen for vaccine development. With the presence of multiple rare sugars and unusual glycosyl linkages, the B. pertussis LPS is a highly challenging synthetic target. In this work, aided by molecular dynamics simulation and modeling, a pertussis-LPS-like pentasaccharide was chemically synthesized for the first time. The pentasaccharide was conjugated with a powerful carrier, bacteriophage Q beta, as a vaccine candidate. Immunization of mice with the conjugate induced robust anti-glycan IgG responses with IgG titers reaching several million enzyme-linked immunosorbent assay (ELISA) units. The antibodies generated were long lasting and boostable and could recognize multiple clinical strains of B. pertussis, highlighting the potential of Q beta-glycan as a new anti-pertussis vaccine.

Human DNA topoisomerase II is one of the major targets in anticancer therapy, however ATP-competitive inhibitors of this target have not yet reached their full potential. ATPase domain of human DNA topoisomerase II belongs to the GHKL ATPase superfamily and shares a very high 3D structural similarity with other superfamily members, including bacterial topoisomerases. In this work we report the discovery of a new chemotype of ATP-competitive inhibitors of human DNA topoisomerase II alpha that were discovered through screening of in-house library of ATP-competitive inhibitors of bacterial DNA gyrase and topoisomerase IV. Systematic screening of this library provided us with 20 hit compounds. 1,2,4-Substituted N-phenylpyrrolamides were selected for a further exploration which resulted in 13 new analogues, including 52 with potent activity in relaxation assay (IC50 = 3.2 mu M) and ATPase assay (IC50 = 0.43 mu M). Cytotoxic activity of all hits was determined in MCF-7 cancer cell line and the most potent compounds, 16 and 20, showed an IC50 value of 8.7 and 8.2 mu M, respectively.

A general and efficient method for the synthesis N-difluoroethyl imides has been developed. This copper-catalyzed four-component reaction proceeds via in-situ generated difluorodiazomethane, which does not require prior formation and transferring. The reaction is scalable, tolerant toward a range of functional groups, and also suitable for the late-stage functionalization of drugs and drug-like molecules.

Metal-organic frameworks (MOFs) have recently emerged as efficient self-sacrificial templates to fabricate porous carbon-supported metal nanoparticles (NPs). Due to observed increased activity, catalysts containing bimetallic NPs represent an active frontier for heterogeneous catalyst development. A strategy to synthesize active catalysts with highly dispersed bimetallic metal/metal oxides within a porous carbon matrixviarapid MOF decomposition using dopants is presented in this paper. A 2,4,6-trinitrotoluene (TNT) additive enhances the rapid thermolysis of the metal-doped Cu-based MOFs to minimize particle aggregation. Catalyst characterization reveals that a secondary metal increases dispersion of both metals over the carbon composite support. The catalyst preparation method influences both the metal particle size and oxidation state. Catalytic performance shows increased rates for 4-nitrophenol reduction even with <1 wt% of added secondary metal. Among the synthesized catalysts, the Ni-CuO@C bimetallic catalyst exhibits outstanding activity. This synthetic strategy is useful for creating highly efficient, robust, non-noble metal catalysts for development of sustainable chemical processes.

Eco-friendly carbocatalyst is extremely desirable in organic catalysis and wastewater treatment. Herein, we reported a one-pot synchronous hydrothermal process to synthesize a highly efficient N doped holey graphene (NHG) carbocatalyst, in which graphene oxide nanosheets are self-assembled, reduced, chemically etched, and simultaneously doped with nitrogen to form a graphene hydrogel in the presence of H2O2 and NH4OH. Benefiting from the good hydrophilicity, unique hierarchical porous structure, large specific surface area (322.1 m(2)g(-1)), and high N content (9.77 at. %), the resultant NHG carbocatalyst exhibits an excellent catalytic performance for the hydrogenation of N-containing unsaturated compounds. In 4-nitrophenol reduction reaction, the NHG carbocatalyst delivers a turnover frequency of 3.32 x 10(-2) min(-1). This catalytic activity is superior to that of the commercial Pd/C (5.0 wt%), other previously reported carbocatalysts, and many noble-metal-based catalysts. Furthermore, the molecular structure analysis combined with density functional theory calculations elucidate metal-free catalytic mechanism of hydrogenation reaction for unsaturated chromophore groups in N-containing organic dyes.

Drug-resistant strains of Mycobacterium tuberculosis are on the rise and have resulted in an urgent need to develop new tuberculosis (TB) drugs. Herein, the development of chromonyl-pyrimidines as a new TB drug scaffold is presented. A library of eleven chromonyl-pyrimidines was synthesised, from which lead compound 6-((2-amino-6-methylpyrimidin-4-yl)amino)-3-benzoyl-2-phenyl-4H-chromen-4-one (MIC=36 mu M against M. tuberculosis) was identified. A second-generation library of seven aryl-substituted chromonyl-pyrimidines was then prepared, with six chromonyl-pyrimidines exhibiting an improved M. tuberculosis growth inhibition (MIC=12.5 mu M). From this work, the potential of chromonyl-pyrimidines as therapeutics for TB is demonstrated.
