An Oculus to Profile and Probe Target Engagement In Vivo: How T-REX Was Born and Its Evolution into G-REX

Here we provide a personal account of innovation and design principles underpinning a method to interrogate precision electrophile signaling that has come to be known as "REX technologies". This Account is framed in the context of trying to improve methods ...

Where Electrophile Signaling and Covalent Ligand-Target Mining Converge

Yimon Aye

Interests in learning how to engineer most effective covalent ligands, identify novel functional targets, and define precise mechanism-of-action are rapidly growing in both academia and pharmaceutical industries. We here illuminate the establishment of a m ...

Hemagglutinin of Influenza A, but not of Influenza B and C viruses is acylated by ZDHHC2, 8, 15 and 20

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Mohamed Adbelalim Gadalla

Hemagglutinin (HA), a glycoprotein of Influenza A viruses and its proton channel M2 are site-specifically modified with fatty acids. Whereas two cysteines in the short cytoplasmic tail of HA contain only palmitate, stearate is exclusively attached to one c ...

Electrophile Signaling and Emerging Immuno- and Neuro-modulatory Electrophilic Pharmaceuticals

Yimon Aye, Jesse Poganik

With a lipid-rich environment and elevated oxygen consumption, the central nervous system (CNS) is subject to intricate regulation by lipid-derived electrophiles (LDEs). Investigations into oxidative damage and chronic LDE generation in neural disorders ha ...

Highly Enantioselective Rhodium(I)-Catalyzed Carbonyl Carboacylations Initiated by C-C Bond Activation

Nicolai Cramer, Laetitia Marie Mélanie Souillart

The lactone motif is ubiquitous in natural products and pharmaceuticals. The Tishchenko disproportionation of two aldehydes, a carbonyl hydroacylation, is an efficient and atom-economic access to lactones. However, these reaction types are limited to the t ...

Synthesis of C-linked Disaccharides and Analogues as Biomimetics of the TF Epitope

Maria Kolympadi

Glycoproteins and glycolipids are major components of the outer surface of mammalian cells. Their carbohydrate moieties, which are directed into the outer environment, serve as ligands for receptor proteins, such as lectins, pathogen proteins and antibodie ...

Synthesis of (E,Z)-1-Alkoxy-3-acyloxy-2-methylpenta-1,3-dienes via Danishefsky-Type Dienes or O-Acylation of Enones

Pierre Vogel, Maris Turks, Sylvain Claude Laclef, Claudia Jana Exner

1-Alkoxy-2-methyl-3-acyloxy-(E,E)-penta-1,3-dienes have been prepared applying among others a modified Danishefsky's general method, including chiral, racemic, and achiral derivatives. ...

Remote trimethylsilyl groups interfering with the ortho deprotonation of fluoroarenes and chloroarenes

Christophe Heiss

(2-Fluorophenyl)trimethylsilane (2-F) and (2-chlorophenyl)trimethylsilane (2-Cl) react with sec-butyllithium or lithium 2,2,6,6-tetramethylpiperidide under permutational hydrogen/metal interconversion (metalation) more slowly than, resp., the corresponding ...
