N-[[1-(5-fluoropentyl)-1H-indazol-3-yl]carbonyl]-L-valine methyl ester (5F-AMB) is a synthetic cannabinoid that has been distributed recently. Although inhalation of 5F-AMB produces adverse effects, such as impaired memory and disturbed consciousness, in humans, the psychopharmacological effects of 5F-AMB in rodents have not been investigated. We first examined the effects of intraperitoneal...

5F-AMB is one of the synthetic cannabinoids (SCs) designed to potentiate the ability to activate cannabinoid 1 (CB1) receptors and is abused worldwide. Although inhalation of 5F-AMB elicits serious adverse effects including impaired memory and consciousness, it is not known whether and how 5F-AMB affects the activity of pyramidal neurons in the medial prefrontal cortex (mPFC), a brain region...
Several lines of evidence suggest the involvement of the raphe-serotonergic neurons in addiction to psychostimulants and some recreational drugs. In this study, we established rat organotypic mesencephalic slice cultures containing the raphe nuclei and examined the effects of sustained exposure to 3,4-methylenedioxymethamphetamine (MDMA) and methamphetamine (METH). Immunostaining for tryptophan...
Psychostimulants including amphetamines and cocaine, opioids including morphine, and some recreational drugs share the ability to cause drug dependence and addiction. Although these drugs of abuse primarily act on distinct molecular targets, such as monoamine transporters or receptors, they finally converge to common neural pathways. Several lines of evidence suggest that their chronic...
