Background: Salvia officinalis has been used successfully for the treatment of hot flushes and excessive sweating during menopause. However, modes of actions have not been elucidated conclusively. We explored its pharmacology beyond any hormonal activity with a focus on neurologic impulse transmission.

Methods: We evaluated plasma and brain extra-cellular fluid (ECF) concentration of MTEP at behaviourally active dose (5mg/kg) using in vivo microdialysis. These values were compared it to the affinity in vitro (receptor binding and FLIPR) and to receptor occupancy in vivo.

Sarizotan 1-[(2R)-3,4-dihydro-2H-chromen-2-yl]-N-[[5-(4-fluorophenyl) pyridin-3-yl]methyl] methenamine, showed an in vivo pharmaco-EEG profile resembling that of methylphenidate which is used in attention deficit/hyperactivity disorder (ADHD). In turn, we tested sarizotan against impulsivity in juvenile rats measuring the choice for large delayed vs. a small immediate reward in a T-maze and obtained encouraging results starting at 0.

We investigated balance and bilateral coordination skills in 33 internationally adopted postinstitutionalized children (16 males, 17 females; age range 8 y 5 mo-15 y 10 mo; mean age 10 y 9 mo; SD 2 y 2 mo) and compared them with 34 non-institutionalized children (21 males, 13 females; age range 8 y 3 mo-14 y 10 mo; mean age 11 y 2 mo; SD 2 y 1 mo) being raised in their birth families.
Method: The children were individually administered the balance and bilateral coordination subtests of the Bruininks-Oseretsky Test of Motor Proficiency in a research laboratory.
Subtype 5 metabotropic glutamate receptors (mGluR5) are abundant in the basal ganglia, amygdala, septum, hippocampus, peripheral sensory neurones and dorsal horn of the spinal cord. Thus, mGluR5 has been implicated in central processes underlying movement control, emotion, learning, and nociception. Different negative allosteric modulators (NAMs) of mGluR5 were repeatedly shown to be efficacious in models of L: -DOPA-induced dyskinesia (LID), anxiety, and some forms of pain.
