Interaction of aromatic isocyanates with n-acetyl-lcysteine under physiological conditions [PDF]
, 2006 Isocyanates are of toxicological relevance since they are considered to cause occupational asthma. The majority of polyurethanes is based on aromatic diisocyanates (e.g., TDI and MDI), they are used for foams, elastomers, adhesives and coatings ...

Low‐Temperature Initiation Enhances HCN and NH3 Formation From Methane and NO Over Pt/Al2O3
Chemistry – A European Journal, EarlyView.Hydrogen cyanide (HCN) was formed from CH4 and NO over Pt/Al2O3 at low temperatures. Increasing NO concentration and optimizing reaction‐start conditions significantly enhanced HCN yield. In situ FTIR and DXAFS measurements revealed that dynamically balancing Pt‑CO and Pt‑CN surface species, particularly their desorption under temperature‑swing ...

A class of carbonic anhydrase I – selective activators
Journal of Enzyme Inhibition and Medicinal Chemistry, 2017 A series of ureido and bis-ureido derivatives were prepared by reacting histamine with alkyl/aryl-isocyanates or di-isocyanates. The obtained derivatives were assayed as activators of the enzyme carbonic anhydrase (CA, EC 4.2.1.1), due to the fact that ...
