Biochem/physiol Actions

m-Trifluoromethyl-diphenyl diselenide (TFDD) is a brain blood barrier penetrant organoselenium compound that exhibits antinociceptive and antidepressant effects in animal models without development of tolerance or withdrawal sighs. m-Trifluoromethyl-diphenyl diselenide acts as opioid system modulator, which attenuates morphine withdrawal signs in mice. It exhibits antioxidant and anti-inflammatory properties which might contribute to neuro protective effects.

Chronic pain and depression often coexist sharing common pathological mechanisms, and available analgesics and antidepressants have demonstrated limited clinical efficacy. Evidence has demonstrated that neuronal oxidative stress, apoptosis, and also glucocorticoid receptor dysregulation facilitate the occurrence and development of both

The opioid withdrawal syndrome is defined as a complex phenomenon involving multiple cellular adaptations, which leads to the emergence of aversive physical and affective signs. The m-trifluoromethyl-diphenyl diselenide (m-CF3-PhSe)2 elicits an antidepressant-like effect by modulating the opioid system in different
