Pulsed and Cyclic Voltammetric Studies of Phenols and Naphthols in Dimethylformamide in Presence of Sodium 4-Vinylbenzenesulfonate

Chemistry
The influence of sodium 4-vinylbenzenesulfonate on the electrooxidation of phenols and naphthols was studied in dimethylformamide (DMF). The usually observed deactivation of phenol in non-aqueous environments was suppressed upon addition of sodium 4 ...

Chiral phosphoric acid catalyzed aminative dearomatization of α-naphthols/Michael addition sequence

Nature Communications, 2019
Catalytic asymmetric dearomatization (CADA) reactions readily convert common aromatic compounds to diverse 3D chiral, polycyclic molecules. Here, the authors report an intermolecular asymmetric dearomatization of nucleophile-tethered α-naphthols ...

2,4-Dinitro-1-naphthol

Acta Crystallographica Section E Structure Reports Online, 2010
In the title compound, C(10)H(6)N(2)O(5), the two fused rings are almost co-planar, with an r.m.s. deviation of 0.0163 Å. The nitro groups are oriented at dihedral angles of 2.62 (11) and 44.69 (11)° with respect to the plane of the parent fused rings. Intra-molecular O-H⋯O and C-H⋯O hydrogen bonds complete S(6) ring motifs.

Gentamicin‐Loaded Carbonate Apatite with Dual Antibacterial and Osteogenic Functions for Combating Surgical Site Infections

Advanced Healthcare Materials, EarlyView.
A bone substitute with gentamicin physically precipitated onto the surface of carbonate apatite exhibits prompt drug release, high bactericidal activity, and osteogenic capacity. Efficient antibacterial activity mitigates early postoperative neutrophil accumulation, the status of which may serve as a potential parameter for evaluating the antibacterial
