Nucleophilic substitution of a phthalimidyl group with morpholine in an N1‐methyl‐1,2,3‐triazole: crystallographic evidence for migration of the methylene bridge

open access: yesActa Crystallographica Section C, EarlyView.
X‐ray crystallography revealed that the reaction of 2‐{[4‐(4‐bromophenyl)‐1H‐1,2,3‐triazol‐1‐yl]methyl}phthalimide with morpholine led to substitution of the phthalimide group, including migration of the substituent from N1 to N2 on the 1,2,3‐triazole ring.2‐{[4‐(4‐Bromophenyl)‐1H‐1,2,3‐triazol‐1‐yl]methyl}phthalimide, C17H11BrN4O, was synthesized by ...

Sites of action of sleep and wake drugs: insights from model organisms [PDF]

open access: yes, 2013
Small molecules have been used since antiquity to regulate our sleep. Despite the explosion of diverse drugs to treat problems of too much or too little sleep, the detailed mechanisms of action and especially the neuronal targets by which these compounds

Diversity and noise effects in a model of homeostatic regulation of the sleep-wake cycle [PDF]

open access: yes, 2012
Recent advances in sleep neurobiology have allowed development of physiologically based mathematical models of sleep regulation that account for the neuronal dynamics responsible for the regulation of sleep-wake cycles and allow detailed examination of ...

The DNA/RNA autophagy protein SIDT2 as a novel neuropathological hallmark in Huntington disease

open access: yesBrain Pathology, EarlyView.
SIDT2‐immunoreactive inclusions are observed in the striatum, cerebral cortex, and hypothalamus in HD cases with different Vonsattel grades, and the frequency of SIDT2‐immunoreactive inclusions is associated with longer CAG repeats in the huntingtin gene.

Merkel cells, a new localization of prepro‐orexin and orexin receptors [PDF]

open access: yesJournal of Anatomy, 2004
AbstractOrexins (OXA and OXB) are peptides derived from a common precursor called prepro‐orexin. They act through G‐protein receptors named orexin 1 receptor (OX1R) and orexin 2 receptor (OX2R). Orexins were first demonstrated in neurons of the lateral hypothalamus and found to be related to the control of food intake.

Temperament and arousal systems: A new synthesis of differential psychology and functional neurochemistry. [PDF]

open access: yes, 2016
This paper critically reviews the unidimensional construct of General Arousal as utilised by models of temperament in differential psychology for example, to underlie 'Extraversion'. Evidence suggests that specialization within monoamine neurotransmitter

Psychedelics, entactogens and psychoplastogens for depression and related disorders

open access: yesBritish Journal of Pharmacology, EarlyView.
Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N‐dimethyltryptamine, ayahuasca; non‐hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g.

Expression of orexin B and its receptor 2 in rat testis [PDF]

open access: yes, 2017
The peptides orexin A (OxA) and orexin B (OxB) deriving from a common precursor molecule, prepro-orexin, by proteolytic cleavage, bind the two G-coupled OX1 and OX2 receptors.
