Minimalist Natural ORPphilin Macarangin B Delineates OSBP Biological Function.

OSBP ligands from the ORPphilin family are chemically complex natural products with promising anticancer properties. Here, we describe macarangin B, a natural racemic flavonoid selective for OSBP, which stands out from other ORPphilins due to its structural simplicity and distinct biological activity. Using a bioinspired strategy, we synthesized both (,,) and (,,)-macarangin B enantiomers, enabling us to study their interaction with OSBP based on their unique optical properties.

Restorative Just Culture: An Exploration of the Enabling Conditions for Successful Implementation.

Background/objectives: Restorative responses to staff involved in incidents are becoming recognized as a rigorous and constructive alternative to retributive forms of 'just culture'. However, actually achieving restoration in mostly retributive working environments can be quite difficult. The conditions for the fair and successful application of restorative practices have not yet been established.

SUPPRESSOR OF MAX2 1-LIKE (SMXL) homologs are MAX2-dependent repressors of Physcomitrium patens growth.

SUPPRESSOR OF MAX2 (SMAX)1-LIKE (SMXL) proteins are a plant-specific clade of type I HSP100/Clp-ATPases. SMXL genes are present in virtually all land plant genomes. However, they have mainly been studied in angiosperms.

How the nature and charge of metal cations affect vibrations in acetone solvent molecules.

Vibrational spectra of a series of gas-phase metal 1+ and 2+ ions solvated by acetone molecules are collected to investigate how the metal charge, number of solvent molecules and nature of the metal affect the acetone. The spectra of Cu(Ace)(N), Cu(Ace), and M(Ace), where M = Co, Ni, Cu, and Zn are measured photodissociation by monitoring fragment ion signal as a function of IR wavenumber. The spectra show a red shift of the CO stretch and a blue shift of the C-C antisymmetric stretch.

"CinNapht" dyes: a new cinnoline/naphthalimide fused hybrid fluorophore. Synthesis, photo-physical study and use for bio-imaging.

Six-membered-diaza ring of cinnoline has been fused on naphthalimide dye to give a donor-acceptor system called CinNapht. This red shifted fluorophore, that can be synthesised in gram scale, exhibits a large Stoke shift and a fluorescence quantum yield up to 0.33.
