The origin of 2,5-dimethoxy-4-methylamphetamine (DOM, STP).

Drug Testing and Analysis December 1, 2024 Keeper Trout, Paul F. Daley 5 citations

The story of the 1967 appearance of the powerful psychedelic 2,5-dimethoxy-4-methylamphetamine (DOM, STP) commonly omits details and often includes hyperbole and inaccuracies. It is well known how and when the drug was first distributed to the public for free by Owsley Stanley, but the role that Alexander Shulgin played in providing that material is not as well understood. In the interest of...

Synthesis and characterization of high‐purity N,N‐dimethyltryptamine hemifumarate for human clinical trials

Drug Testing and Analysis July 1, 2020 Nicholas V. Cozzi, Paul F. Daley 12 citations

Abstract Since 2006, there has been a resurgent interest in the pharmacology and therapeutics of psychedelic drugs. Psilocybin, the 4‐phosphoryl ester of N,N ‐dimethyltryptamine (DMT), has been studied most often, but DMT itself is also appealing because of its brief but profound psychological effects and its presence as an endogenous substance in mammalian brain. Although there have been a few...

Receptor binding profiles and behavioral pharmacology of ring-substituted N,N-diallyltryptamine analogs.

Neuropharmacology November 1, 2018 Landon M. Klein, Nicholas V. Cozzi, Paul F. Daley et al. 43 citations

Substantial effort has been devoted toward understanding the psychopharmacological effects of tryptamine hallucinogens, which are thought to be mediated by activation of 5-HT2A and 5-HT1A receptors. Recently, several psychoactive tryptamines based on the N,N-diallyltryptamine (DALT) scaffold have been encountered as recreational drugs. Despite the apparent widespread use of DALT derivatives in...

Receptor binding profiles and quantitative structure-affinity relationships of some 5-substituted-N,N-diallyltryptamines.

Bioorganic & Medicinal Chemistry Letters February 1, 2016 Nicholas V. Cozzi, Paul F. Daley 24 citations

N,N-Diallyltryptamine (DALT) and 5-methoxy-N,N-diallyltryptamine (5-MeO-DALT) are two tryptamines synthesized and tested by Alexander Shulgin. In self-experiments, 5-MeO-DALT was reported to be psychoactive in the 12-20mg range, while the unsubstituted compound DALT had few discernible effects in the 42-80 mg range. Recently, 5-MeO-DALT has been used in nonmedical settings for its psychoactive...

Pharmacological examination of trifluoromethyl ring-substituted methcathinone analogs.

European Journal of Pharmacology November 21, 2012 Nicholas V. Cozzi, Simon D. Brandt, Paul F. Daley et al.

Cathinones are a class of drugs used to treat various medical conditions including depression, obesity, substance abuse, and muscle spasms. Some "designer" cathinones, such as methcathinone, mephedrone, and methylone, are used nonclinically for their stimulant or entactogenic properties. Given the recent rise in nonmedical use of designer cathinones, we aimed to improve understanding of...

Synthesis and characterization of 5‐methoxy‐2‐methyl‐N,N‐dialkylated tryptamines

Drug Testing and Analysis 2012 Simon D. Brandt, Ruchanok Tearavarich, Nicola M. Dempster et al. 10 citations

The absence of reference material is a commonly experienced difficulty among medical and forensic professionals tasked with identifying new psychoactive substances that are encountered for the first time. The identification of newly emerging substances lies at the heart of forensic and clinical analysis, and a proactive public health policy calls for a thorough analysis of the properties of new...

The designer methcathinone analogs, mephedrone and methylone, are substrates for monoamine transporters in brain tissue.

Neuropsychopharmacology December 14, 2011 Michael H Baumann, Mario A Ayestas, John S. Partilla et al.

The nonmedical use of 'designer' cathinone analogs, such as 4-methylmethcathinone (mephedrone) and 3,4-methylenedioxymethcathinone (methylone), is increasing worldwide, yet little information is available regarding the mechanism of action for these drugs. Here, we employed in vitro and in vivo methods to compare neurobiological effects of mephedrone and methylone with those produced by the...

Microwave‐accelerated preparation and analytical characterization of 5‐ethoxy‐N,N‐dialkyl‐[α,α,β,β‐H4]‐ and [α,α,β,β‐D4]‐tryptamines

Drug Testing and Analysis December 29, 2010 Ruchanok Tearavarich, Viwat Hahnvajanawong, Nicola M. Dempster et al. 10 citations

The increased interest in N,N-dialkyl tryptamines is a reflection of their diverse range of biologically active properties. Deuterated derivatives are of interest for use as internal standards in bioanalytical or pharmacological assays. The present study reports on the synthesis of twelve novel 5-ethoxy-N,N-dialkyl-[α,α,β,β-H(4) ]-tryptamines and their [α,α,β,β-D(4) ]-counterparts following the...

New mescaline concentrations from 14 taxa/cultivars of Echinopsis spp. (Cactaceae) (“San Pedro”) and their relevance to shamanic practice

Journal of Ethnopharmacology July 15, 2010 Olabode Ogunbodede, Douglas Mccombs, Keeper Trout et al. 54 citations

Aim of the studyThe aim of the present study is to determine in a procedurally uniform manner the mescaline concentrations in stem tissue of 14 taxa/cultivars of the subgenus Trichocereus of the genus Echinopsis (Cactaceae) and to evaluate the relationship (if any) between mescaline concentration and actual shamanic use of these plants.Materials and methodsColumnar cacti of the genus...

Dimethyltryptamine and other hallucinogenic tryptamines exhibit substrate behavior at the serotonin uptake transporter and the vesicle monoamine transporter.

Journal of Neural Transmission September 12, 2009 Nicholas V. Cozzi, Anupama Gopalakrishnan, Lyndsey L. Anderson et al. 144 citations

N,N-dimethyltryptamine (DMT) is a potent plant hallucinogen that has also been found in human tissues. When ingested, DMT and related N,N-dialkyltryptamines produce an intense hallucinogenic state. Behavioral effects are mediated through various neurochemical mechanisms including activity at sigma-1 and serotonin receptors, modification of monoamine uptake and release, and competition for...
