Identification of Staphylococcus aureus Cellular Pathways Affected by the Stilbenoid Lead Drug SK-03-92 Using a Microarray

Antibiotics, 2017
The mechanism of action for a new lead stilbene compound coded SK-03-92 with bactericidal activity against methicillin-resistant Staphylococcus aureus (MRSA) is unknown. To gain insight into the killing process, transcriptional profiling was performed on

Combination of carbon nanotubes and two-photon absorbers for broadband optical limiting [PDF]

, 2004
New systems are required for optical limiting against broadband laser pulses. We demonstrate that the association of non-linear scattering from single-wall carbon nanotubes (SWNT) and multiphoton absorption (MPA) from organic chromophores is a promising ...

Switching behaviour of stilbene molecular device: a first-principles study

Condensed Matter Physics, 2018
The switching behaviour of stilbene molecular system (SMS) device is investigated with the help of non-equilibrium Green’s function (NEGF) approach using first principles calculation. The transmission spectrum of cis-isomers confirmed that more electrons

Could Polyphenols Help in the Control of Rheumatoid Arthritis?

Molecules, 2019
Rheumatoid arthritis (RA) is a chronic, systemic, joint-invading, autoimmune inflammatory disease, which causes joint cartilage breakdown and bone damage, resulting in functional impairment and deformation of the joints. The percentage of RA patients has

Cyclization vs. Cyclization/Dimerization in o-Amidostilbene Radical Cation Cascade Reactions: The Amide Question

Molecules, 2011
The n-butyramido, isobutyramido, benzamido, and furancarboxamido functions profoundly modulate the electronics of the stilbene olefinic and NH groups and the corresponding radical cations in ways that influence the efficiency of the cyclization due ...

Two-photon absorption and broadband optical limiting with bis-donor stilbenes [PDF]

, 1997
Large two-photon absorptivities are reported for symmetrical bis-donor stilbene derivatives with dialkylamino or diphenylamino groups. These molecules exhibit strong optical limiting of nanosecond pulses over a broad spectral range in the visible ...
