Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Rapid screening of melamine in dried milk without destroying the samples by Raman spectroscopy [PDF]

open access: yes, 2009
Melamine is a raw ingredient for plastics, but it is frequently misused by adding it to food to give the false impression of a high protein content, since the molecule has a very high nitrogen content. Samples of dried milk obtained from 5 manufacturers

Bis(trifluoromethyl)disulfide and the EtP4 Phosphazene Base—Formation of a Bench‐Stable [EtP4SCF3]+[SCF3]− Salt

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of a bench‐stable trifluoromethylthiolate‐substituted phosphazenium salt is reported. Reaction of bis(trifluoromethyl)disulfide with the EtP4 phosphazene base furnishes this salt in quantitative yield. The compound features a unique trifluoromethylthiolate‐iminium motif and allows for functionalization of both trifluoromethylthiolate ...

Reduction of Moisture Effects During the Cure of Epoxy Adhesives Used in Composite Repair [PDF]

open access: yes, 1985
The requirements for repair work on Naval aircraft composite wing skins that can be performed under depot conditions (or still worse, under field conditions) are quite restrictive.

State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...

Transmembrane potential polarization, calcium influx, and receptor conformational state modulate the sensitivity of the imidacloprid-insensitive neuronal insect nicotinic acetylcholine receptor to neonicotinoid insecticides [PDF]

open access: yes, 2012
Neonicotinoid insecticides act selectively on insect nicotinic acetylcholine receptors (nAChRs). Recent studies revealed that their efficiency was altered by the phosphorylation/dephosphorylation process and the intracellular signaling pathway involved ...

Hydroquinone Oxidation by Redox‐active Guanidines and Thioguanidines: Faster Conversion to High‐Potential Than to Low‐Potential Quinones

open access: yesChemistry – A European Journal, EarlyView.
New redox‐active oligothioguanidines are developed and used in dehydrogenative P–P coupling reactions and hydroquinone oxidations. Tetrathioguanidino‐ and tetraguanidinobenzenes oxidize high‐potential halogenated hydroquinones faster than relatively low‐potential hydroquinone.

Photochemistry of N-(selenoalkyl)-phthalimides. Formation of N, Se-heterocyclic systems [PDF]

open access: yes, 2015
A variety of N-(selenomethyl)alkyl-phthalimides (alkyl = -(CH2)n-; n = 2-5, 1a, b, d, e) and N-(selenobenzyl)propyl phthalimide (1c) were synthesized and their photochemistry was studied at λ = 300 nm.
