Immunological Abnormalities and Hydantoins [PDF]
BMJ, 1972 Various immunological features were measured in 20 patients with epilepsy who had received prolonged treatment with hydantoins. Immunoglobulin A (IgA) was shown to be absent or low in five patients, β 1 C/A was low in 10 patients. Five patients showed negative reactions to skin tests, and two

The Pyroglutamate Hydantoin Rearrangement [PDF]
European Journal of Organic Chemistry, 2006 Abstract When a mixture of a pyroglutamate and an isocyanate in THF is treated with NaH, a ring transformation occurs leading to functionalised hydantoins. The novel reaction involves a ring‐closing ring‐opening sequence providing a new and straightforward access to an interesting class of heterocyclic compounds. Furthermore, starting

Angewandte Chemie, EarlyView.A coumarin‐based dual‐emission fluorophore was designed to visualize the maturation of protein liquid droplets. Upon covalent conjugation to droplet‐forming proteins, ratiometric fluorescence imaging allowed real time monitoring of droplet maturation. This probe is applicable to the analysis of droplet formation and maturation mechanisms, as well as to
