Perspectives in biomedicine: Superfoods and antioxidant power classification
The Canadian Journal of Chemical Engineering, EarlyView.Abstract The market value of natural food antioxidants will double to 8 billion USD by 2033, driven by a global consumer demand for ‘clean label’ products and proactive wellness solutions. However, the industrial application and health labelling (commercial brands) of these compounds remain severely constrained by inconsistent analytical methods.

Isoform Specificity of a Compound Targeting Actin Filaments Containing Tropomyosin Tpm1.8/1.9
Cytoskeleton, EarlyView.ABSTRACT The unbranched actin filaments in mammalian cells are usually composed of co‐polymers of a specific tropomyosin isoform with actin. Genetic manipulation has revealed that the tropomyosins largely define the functional properties of actin filaments in an isoform‐specific, non‐redundant manner.

Ullmann‐Type N‐Heteroarylation of Nitrogen Heterocycles Catalyzed by Heterogeneous CuNPs/HKUST‐1
EcoEnergy, EarlyView.A practical strategy for the direct synthesis of CuNPs/HKUST‐1 heterogeneous catalyst was developed and used for the catalyzing Ullmann‐type N‐arylation of N‐heterocycles with high yields, excellent recyclability, and low copper leaching. ABSTRACT Ullmann‐type C–N coupling is an essential reaction to construct functional nitrogen heterocycles, whereas ...

European Journal of Organic Chemistry, EarlyView.Quinine‐catalyzed enantioselective conjugate addition of malononitrile derivatives to enynes provides trisubstituted chiral allenes in good to excellent yields and high enantiopurities under mild conditions. Broad substrate scope, easy scalability, and versatile post‐synthetic transformations into enantioenriched pyrazoles and furans highlight the ...

Antiplasmodial Bis-Indole Alkaloids from the Bark of Flindersia pimenteliana
, 2020 Three new (1-3) and 2 known (4-5) bis-indole alkaloids were identified from the bark of Flindersia pimenteliana (Rutaceae). The structures of 1-3 were elucidated on the basis of their (+)-HRESESIMS and 2D NMR spectroscopic data.
