Probing the molecular determinants of emission enhancement in RNA aptamer–metal complex systems
Photochemistry and Photobiology, EarlyView.Light up aptamer: fluorophore pairs are widely used in sensing and imaging, with coordination complex fluorophores providing specific benefits due to their long‐lived emission. Here, we examined key structural and electronic features of these metal complexes to identify the requirements for productive engagement with an RNA aptamer.

Formation of the Imidazolinone Ring Under Mild Conditions in the Presence of Sodium Hydride
Molecules, 2004 Substituted imidazolinones containing heterocyclic carboxylic acids as substituents and possessing herbicidal properties were synthesized by cyclization of 2-amino-2,3-dimethylbutyramide with heterocyclic ethyl dicarboxylates under mild conditions.

An Investigation into the asymmetric synthesis of imidazolinones via reaction of chiral alpha-amino acid esters with nitrils [PDF]
, 1991 The objective of this investigation was to develop a new synthetic method for the asymmetric synthesis of imidazolinones. This method involved an addition-cyclization reaction of an optically pure alpha-amino acid ester and a nitrile.

Advanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.A metal‐free PIII/PV redox organocatalytic aza‐Wittig reaction enables the efficient cyclization of azide‐functionalized imides into pharmaceutically relevant amidine‐containing heterocycles. Using only 2 mol% of a methanophosphocine catalyst and a Brønsted acid additive, a broad range of substrates is converted in up to 96% yield, including ...

Scientific Opinion on waiving of the dog studies in the regulatory process of agrochemicals approval
EFSA Journal, Volume 24, Issue 7, July 2026.Abstract Commission Regulation (EU) No. 283/2013 sets out the data requirements for pesticide active substances and includes short‐term oral toxicity testing in rodents (90‐day rat study) and non‐rodents (90‐day dog study) to support human health hazard assessment for pesticide active substances in the European Union (EU). However, the relevance of the
