Enhanced Catalytic Activity of Crystalline Phosphorus Nanosheets Fabricated Solvothermal Phase Transformation.

The newly reported crystalline phosphorus nanosheets (cryst-P NSs) exhibit promising features for industrial applications, including outstanding air-water stability and facile large-scale production. However, their complex crystallization impedes tailoring. Herein, the temporal evolution of cryst-P NSs was investigated with the optimized synthesis parameters.

Structures and biochemical evaluation of silver(I) 5,5-diethylbarbiturate complexes with bis(diphenylphosphino)alkanes as potential antimicrobial and anticancer agents.

New silver(I) 5,5-diethylbarbiturate (barb) complexes with a series of bis(diphenylphosphino)alkanes such as 1,1-bis(diphenylphosphino)methane (dppm), 1,2-bis(diphenylphosphino)ethane (dppe), 1,3-bis(diphenylphosphino)propane (dppp) and 1,4-bis(diphenylphosphino)butane (dppb) were synthesized and characterized. [Ag(barb)(μ-dppm)] (1), [Ag(barb)(μ-dppe)(DMSO)] (2) and [Ag(barb)(μ-dppp)] (3) were binuclear, while [Ag(barb)(μ-dppb)] (4) was a coordination polymer. 1-4 effectively bind to the G/C rich region of the major groove of DNA and interact with BSA via hydrophobic interactions in accordance with molecular docking studies.

Synthesis, structures and biomolecular interactions of new silver(i) 5,5-diethylbarbiturate complexes of monophosphines targeting Gram-positive bacteria and breast cancer cells.

A series of new silver(i) 5,5-diethylbarbiturate (barb) complexes with the formulas [Ag(μ-barb)(PPh)] (1), [Ag(barb)(PPhCy)] (2), [Ag(barb)(PPhCy)] (3) and [Ag(barb)(PCy)] (4) (PPh = triphenylphosphine, PPhCy = diphenylcyclohexylphosphine, PPhCy = dicyclohexylphenylphosphine and PCy = tricyclohexylphosphine) were synthesized and fully characterized by elemental analysis, IR, NMR, ESI-MS and X-ray crystallography. All the complexes display a significant affinity towards DNA with a groove binding mode and also strongly bind to BSA via hydrophobic interactions. Lipophilicity increases from 1 to 4 with an increasing number of Cy groups in the phosphine ligands.
