Organocatalytic Formal (3+2+1)‐Cycloaddition of Allenoates, Michael Acceptors, and Carbaldehydes

Chemistry – A European Journal, EarlyView.
The use of secondary amine Lewis base organocatalysts allows for the unprecedented activation of allenoates for formal (3+2+1)‐cycloadditions with Michael acceptors and aromatic carbaldehydes. ABSTRACT Employing secondary amines as covalently interacting Lewis basic organocatalysts allows for the activation of electron‐deficient allenes (allenoates ...

Increased GABA(A) receptor ε-subunit expression on ventral respiratory column neurons protects breathing during pregnancy. [PDF]

PLoS ONE, 2012
GABAergic signaling is essential for proper respiratory function. Potentiation of this signaling with allosteric modulators such as anesthetics, barbiturates, and neurosteroids can lead to respiratory arrest.

Cenobamate use in super‐refractory status epilepticus: A report of three cases

Epileptic Disorders, EarlyView.
Abstract Objectives Super‐refractory status epilepticus (SRSE) is a neurological emergency with high morbidity and mortality. Cenobamate, a novel antiseizure medication, may be helpful in managing SRSE, but evidence is limited. Methods This retrospective case series reports the use of cenobamate as add‐on therapy in the management of three cases of ...

Determination of barbiturates in hair samples by using a validated UHPLC-HRMS method: application in investigation of drug-facilitated sexual assault

Forensic Sciences Research, 2019
In recent years, benzodiazepines and benzodiazepine-like drugs are the most common substances associated with drug-facilitated sexual assaults (DFSA); however, barbiturates are also detected occasionally.
