R (−)‐2,5‐Dimethoxy‐4‐iodoamphetamine (DOI) and other compounds with agonist affinity for serotonergic 5‐HT2A receptors are hallucinogenic drugs of abuse, but also have therapeutic potential in numerous neuropsychiatric conditions, including major depressive disorder, post‐traumatic stress disorder, and in the treatment of migraine and cluster headaches. Thus, commonly abused hallucinogens...

Only recently has the full therapeutic value of serotonin [5‐hydroxytryptophan (5‐HT)] receptor activation begun to be explored. Currently there are two 5‐HT 2A receptor agonists in human clinical trials for the treatment of depression and obesity. An exciting new therapeutic avenue in which 5‐HT 2A agonists might be employed is the modulation of inflammation in allergic airways disease. Our...

Spiritual retreats are a commonly used intensive program of meditation and prayer, along with other elements, designed to provide participants with opportunities for spiritual and psychological growth. While individual elements of such retreats have been studied, there have been no reports in the literature regarding the neurophysiological effects of these retreats. This preliminary study...

A core aspect of the human self is the attribution of personal relevance to everyday stimuli enabling us to experience our environment as meaningful [1]. However, abnormalities in the attribution of personal relevance to sensory experiences are also critical features of many psychiatric disorders [2, 3]. Despite their clinical relevance, the neurochemical and anatomical substrates enabling...

SUMMARY The prototypical hallucinogen LSD acts via serotonin receptors, and here we describe the crystal structure of LSD in complex with the human serotonin receptor 5-HT2B. The complex reveals conformational rearrangements to accommodate LSD, providing a structural explanation for the conformational selectivity of LSD’s key diethylamide moiety. LSD dissociates exceptionally slowly from both...

Growing evidence indicates that serotonergic neurons play a crucial role in brain function and dysfunction, such as in major depressive disorder. However, the complexity of serotonergic projections severely hampers the elucidation of their precise mechanisms. Here we summarize our recent studies on the effects of ketamine and olanzapine, which have been reported to be effective in...

he trend of drug use has changed tremendously in this millennium (Adnan et al., 2014). Over the past decade, opioids are among the primary drug of abuse in worldwide. However the trend towards using amphetamine-type stimulant (ATS) is notably increasing lately. Amphetamine-type stimulants are a group of drugs consisting mainly of amphetamine and metamphetamine; these include methcathinone,...

Unlike classic serotonergic antidepressant drugs, ketamine, an NMDA receptor antagonist, exhibits a rapid and persistent antidepressant (AD) activity, at sub-anaesthetic doses in treatment-resistant depressed patients and in preclinical studies in rodents. The mechanisms mediating this activity are unclear. Here, we assessed the role of the brain serotonergic system in the AD-like activity of...

Two low-molecular-weight compounds were isolated from the parotid gland secret of the toad Bufo bufo, which by absorption spectra and HPLC-MS/MS chromatography data correspond to di- and trimethyl derivatives of serotonin (5-hydorxytryptamine): bufotenine (confirmed by counter synthesis) and bufotenidine (5-HTQ). In experiments on competitive radioligand binding, these compounds showed a higher...

As is the case with other drugs of abuse, a proportion of ecstasy users develop symptoms consistent with a substance use disorder (SUD). In this paper, we propose that the pharmacology of MDMA, the primary psychoactive component of ecstasy tablets, changes markedly with repeated exposure and that neuroadaptations in dopamine and serotonin brain systems underlie the shift from MDMA use to MDMA...
