The use of phenethylamines in the dance scene is now well established. Apart from amphetamine, the commonest phenethylamine encountered in clinical and forensic settings is 3,4-methylenedioxymethamphetamine (MDMA) commonly known as ecstasy. Other phenethylamines, which have similar effects are encountered, such as 3,4-methylenedioxyethylamphetamine (MDEA) and their use has resulted in death. We...

In an attempt to increase the selectivity of drug discrimination, rats were trained to discriminate LSD (0.08 mg/kg) from a group of "other" compounds consisting of cocaine (10 mg/kg), pentobarbital (5 mg/kg), and saline. Acquisition of this LSD-other discrimination was rapid (31 days) in chambers equipped with retractable levers and did not differ significantly from that of a group of animals...

The 3,4-methylenedioxy analogues of amphetamine [MDMA ("Ecstasy", "Adam"), MDA ("Love") and MDE ("Eve")] are recreational drugs that produce feelings of euphoria and energy and a desire to socialize, which go far to explain their current popularity as "rave drugs". In addition to these positive effects, the drugs are relatively inexpensive to purchase and have the reputation of being safe...

A literature review on 3,4 methylenedioxymethanphetaneine (MDMA), known as ecstasy, a drug with increased use among youngsters is presented. The history from its synthesis, up to its use as an adjunct to psychotherapy and, more recently, as a drug of abuse, is described. The possible pattern of abuse in several countries is reviewed with the objective of predicting what might happen in Brazil,...

Synaptopathies (Fall, 2022) Synaptic neurotransmission lies at the heart of nervous system's functioning. Clearly then, alterations in synaptic signal transduction can lead to a variety of neural disorders. Perhaps the most widely known of these disorders include certain movement disorders and myasthenia gravis. More recent interest in synaptic dysfunction has focused on neurodevelopmental and...

The acute effects of amphetamine derivatives on extracellular concentration of serotonin (5-HT) and dopamine in the nucleus accumbens were studied with in vivo microdialysis using conscious, freely moving rats. 5-HT, dopamine, and their major metabolites were measured by HPLC with electrochemical detection. Amphetamine (1.0-9.0 mg/kg) elevated dopamine levels considerably, but failed to affect...

Structurally, methcathinone is to cathinone what methamphetamine is to amphetamine. Due to increased interest in the abuse of such agents we wished to determine if certain derivatives of cathinone would behave in a manner consistent with what is known about their amphetamine counterparts; that is, can amphetamine structure-activity relationships be extrapolated to cathinone analogs? As expected...

Religious experience is brain-based, like all human experience. Clues to the neural substrates of religious-numinous experience may be gleaned from temporolimbic epilepsy, near-death experiences, and hallucinogen ingestion. These brain disorders and conditions may produce depersonalization, derealization, ecstasy, a sense of timelessness and spacelessness, and other experiences that foster...

The interaction of fifteen amphetamine analogs with the genetically polymorphic enzyme CYP2D6 was examined. All fourteen phenylisopropylamines tested were competitive inhibitors of CYP2D6 in human liver microsomes. The presence of a methylenedioxy group in the 3,4-positions of both amphetamine (Ki = 26.5 microM) and methamphetamine (Ki = 25 microM) increased the affinity for CYP2D6 to 1.8 and...

Ten male N/Nih rats were trained to discriminate between the interoceptive cues produced by the purportedly dopaminergically-mediated drug d-amphetamine at 0.4 mg/kg intraperitoneally administered 20 min prior to training and those produced by the purportedly serotonergically-active agent norfenfluramine at 0.7 mg/kg. Once this discrimination was successfully acquired, the rats were tested with...
