Increase of Exhaled Nitric Oxide (eNO) after Methylene Diphenyl Diisocyanate (MDI) Exposure in Isocyanate Workers with Bronchial Hyperresponsiveness

Allergology International, 2005
Background: : Isocyanates have become one of the most important causes of occupational asthma in industrialized countries. Increased exhaled nitric oxide (eNO) levels have been shown to be associated with allergic airway inflammation.

Transformative Chemie maskierter Ortho‐Chinone: Über die direkte Aktivierung von Guajacol zu Lignin‐basierten Klebstoffen

Angewandte Chemie, EarlyView.
Erneuerbare Guajacole werden durch Phenyliodid(III)diacetat rasch zu maskierten ortho‐Chinonen oxidiert und bilden eine neue Monomerklasse, die mit Multithiolen selektive Michael‐Typ‐Polyadditionen zu Polymeren mit Thiol‐Guajacol‐Verknüpfungen eingeht.

Transformative Masked Ortho‐Quinone Chemistry: From Direct Guaiacol Activation to Lignin‐Based Adhesives

Angewandte Chemie International Edition, EarlyView.
Renewable guaiacols are rapidly oxidized by phenyliodine(III)diacetate to masked ortho‐quinones, giving a new class of monomers that undergo selective Michael‐type polyaddition with multithiols to from thiol‐guaiacol connectivity‐bearing polymers. The activation applies to discrete monomers and directly to lignin, enabling two‐component adhesives that ...

Associations Between Glutathione-S-Transferase Genotypes and Bronchial Hyperreactivity Patients With Di-isocyanate Induced Asthma. A Follow-Up Study

Frontiers in Medicine, 2019
Introduction: Di-isocyanates TDI (toluene di-isocyanate), MDI (diphenylmethane di-isocyanate), and HDI (hexamethylene di-isocyanate) are the most common chemicals causing occupational asthma. Di-isocyanate inhalation has been reported to induce oxidative

Precision Chemistry for Protein Lysine Modification. [PDF]

Chemistry
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.
