High-throughput screening in larval zebrafish identifies novel potent sedative-hypnotics [PDF]

, 2018
BACKGROUND: Many general anesthetics were discovered empirically, but primary screens to find new sedative-hypnotics in drug libraries have not used animals, limiting the types of drugs discovered.

Anxiolytic Effects of Indole Alkaloids From Rauvolfia ligustrina in Adult Zebrafish: Involvement of the GABAergic and 5‐HT Systems

Chemistry &Biodiversity, EarlyView.
ABSTRACT Benzodiazepines are widely used in the treatment of anxiety, but their use may be interrupted due to side effects. This study evaluated the indole alkaloids isocarapanaubine (indole alkaloid 1 [AIN1]) and 18‐β‐hydroxy‐3‐epi‐α‐yohimbine (indole alkaloid 2 [AIN2]), extracted from Rauvolfia ligustrina, in adult zebrafish.

The effect of Midazolam and Propranolol on fear memory reconsolidation in ethanol-withdrawn rats: Influence of D-cycloserine [PDF]

, 2014
Background: Withdrawal from chronic ethanol facilitates the formation of contextual fear memory and delays the onset to extinction, with its retrieval promoting an increase in ethanol consumption.

Stereoselective Synthesis of Cannabidiol and its Unnatural Enantiomer to Evaluate Anxiolytic‐Like Properties and Memory Interactions

ChemBioChem, EarlyView.
Both (−)‐ and (+)‐cannabidiol (CBD and ent‐CBD, respectively) are synthesized via a highly diastereoselective CSA‐catalyzed Friedel–Crafts reaction. ent‐CBD exhibits anxiolytic‐like effects in aged male mice without impairing long‐term memory formation.

Interaction of GABA and Excitatory Amino Acids in the Basolateral Amygdala: Role in Cardiovascular Regulation [PDF]

, 1997
Activation of the amygdala in rats produces cardiovascular changes that include increases in heart rate and arterial pressure as well as behavioral changes characteristic of emotional arousal.

NSAIDS AS MODULATORS OF CATION CHANNELS: FENAMATES REPURPOSING IN CHANNELOPATHIES

ChemMedChem, Accepted Article.
Cationic ion channels are transmembrane proteins that regulate the flux of cations (potassium, sodium, and calcium) across cell membrane, playing a pivotal role in many cellular functions. Disruptions of their activity can lead to the so‐called genetic or acquired channelopathies, a heterogeneous group of diseases that affect multiple human systems ...

GABA\u3csub\u3eA\u3c/sub\u3e and excitatory amino acid receptors in dorsomedial hypothalamus and heart rate in rats [PDF]

, 1991
We have previously shown that microinjection of drugs that interfere with the function of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) into the hypothalamus produces cardiorespiratory and behavioral changes resembling those seen in ...

A head start: The relationship of placental factors to craniofacial and brain development

Developmental Dynamics, EarlyView.
Abstract In recent years, the importance of placental function for fetal neurodevelopment has become increasingly studied. This field, known as neuroplacentology, has greatly expanded possible etiologies of neurodevelopmental disorders by exploring the influence of placental function on brain development.

GABAA receptor plasticity in Jurkat T cells

Biochimie, 2013
GABAA receptors (GABAAR) mediate inhibitory neurotransmission in the human brain. Neurons modify subunit expression, cellular distribution and function of GABAAR in response to different stimuli, a process named plasticity. Human lymphocytes have a functional neuronal-like GABAergic system with GABAAR acting as inhibitors of proliferation.

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.
