Addex Therapeutics Publishes Preclinical Research on ADX71743

Addex Therapeutics announced publication of new preclinical research demonstrating that ADX71743, a selective negative allosteric modulator of metabotropic glutamate receptor 7, significantly modulates sleep-wake regulation and stress-related neurochemistry in animal models. The data, published in the International Journal of Neuropsychopharmacology, expands the growing body of evidence supporting mGlu7 as an important mechanism regulating key brain functions and a promising therapeutic target across a range of central nervous system disorders, including mood disorders, anxiety disorders, post-traumatic stress disorder, and other conditions associated with dysregulated stress responses. In the study, ADX71743 increased wakefulness while reducing both REM and non-REM sleep in rats. The compound also altered stress-induced changes in key neurotransmitters, including glutamate, GABA and monoamines, across multiple brain regions in awake animals, producing neurochemical effects consistent with modulation of stress-responsive neural circuits. Together, these findings further validate the pharmacological profile of selective mGlu7 inhibition in vivo and provide additional support for the therapeutic potential of this novel mechanism. Previous studies have demonstrated that selective mGlu7 inhibition can modulate anxiety-related behaviors, disrupt maladaptive fear memory reconsolidation and influence glutamatergic signaling in both rodent and human brain tissue.
