Rhodamine inhibitors of P-glycoprotein: an amide/thioamide "switch" for ATPase activity.
TLDR
In MDCKII-MDR1 cells, the tertiary thioamide- containing derivatives promote uptake of calcein AM and have very slow passive, absorptive, and secretory rates of transport relative to transport rates for tertiary amide-containing derivatives.

Barnacle settlement and the adhesion of protein and diatom microfouling to xerogel films with varying surface energy and water wettability
TLDR
Modifications of chemistry were investigated with respect to their resistance to marine slimes and to settlement of barnacle cyprids to find hydrophilic xerogels should prove useful as coatings for boats in regions where fouling is dominated by microfouling.

The ATPase Activity of the P-glycoprotein Drug Pump Is Highly Activated When the N-terminal and Central Regions of the Nucleotide-binding Domains Are Linked Closely Together*
TLDR
The results suggest that trapping P-gp in a conformation in which the NBDs are closely associated likely mimics the structural rearrangements caused by binding of drug substrates that stimulate ATPase activity.

Antifouling character of ‘active’ hybrid xerogel coatings with sequestered catalysts for the activation of hydrogen peroxide
TLDR
Scanning electron microscopy and XPS data suggest that exposure to H2O2 does not lead to chemical or morphological changes on the xerogel surface.

Through tissue imaging of a live breast cancer tumour model using handheld surface enhanced spatially offset resonance Raman spectroscopy (SESORRS)† †Electronic supplementary information (ESI)…
TLDR
Detection of a live 3D tumour model through 15 mm of tissue using SESORRS shows good response to laser-spot assisted angiogenesis in patients with central giant cell granuloma.

GPx-Like activity of selenides and selenoxides: experimental evidence for the involvement of hydroxy perhydroxy selenane as the active species.
TLDR
While electronic substituent effects have minimal impact on the catalytic performance of selenoxides, chelating groups increase the rate of catalysis.

Isoselenazolones as catalysts for the activation of bromine: bromolactonization of alkenoic acids and oxidation of alcohols.
TLDR
Steric effects from an N-phenylethyl group on the amide of the isoselenazolone and electron-withdrawing fluoro substituents on the benzo fused-ring appear to enhance the stability of theIsoselenzolone as a catalyst for the bromination reaction.

Tellurium Analogues of Rosamine and Rhodamine Dyes: Synthesis, Structure, 125Te NMR, and Heteroatom Contributions to Excitation Energies
The first tellurium-containing analogues of the rosamine and rhodamine dyes were prepared by the addition of Grignard or organolithium reagents to telluroxanthone precursors. The 125Te spectra of…
