Screening of Hallucinogenic Compounds and Genomic Characterisation of 40 Anatolian Salvia Species

July 19, 2017 / Papers, Pharmacology & Chemistry, Salvia / Salvinorin A / By / , , , , ,

Abstract

Introduction
Salvia, an important and widely available member of Lamiaceae family. Although comparative analysis on secondary metabolites in several Salvia species from Turkey has been reported, their hallucinogenic chemicals have not been screened thoroughly.
Objective
This study provides LC–MS/MS analysis of 40 Salvia species for screening their psychoactive constituents of salvinorin A and salvinorin B. 5S–rRNA gene non-coding region of Salvia plants was sequenced, aligned and compared with that sequence of Salvia divinorum plant.
Methodology
Targeted molecules of salvinorin A and salvinorin B were quantified, using LC–MS/MS, from all aerial parts of 40 Salvia species, collected from different parts of Turkey. Regions of 5S–rRNA gene from different species were amplified by polymerase chain reaction and DNA sequences were aligned with Salvia divinorum DNA sequences.
Results
Very few of the Salvia species (S. recognita, S. cryptantha and S. glutinosa) contained relatively high levels of salvinorin A (212.86 ± 20.46 μg/g, 51.50 ± 4.95 μg/g and 38.92 ± 3.74 μg/g, respectively). Salvinorin B was also found in Salvia species of S. potentillifolia, S. adenocaulon and S. cryptantha as 2351.99 ± 232.22 μg/g, 768.78 ± 75.90 μg/g and 402.24 ± 39.71 μg/g, respectively. The sequences of 5S–rRNA gene of 40 different Salvia species were presented and it was found that none of the Salvia species in Turkey had similar DNA sequence to Salvia divinorum plant.
Conclusion
This is the first report of screening 40 Salvia species in Turkey according to their psychoactive constituents, salvinorin A and salvinorin B and their genomic structures. It is possible that some of these Salvia species may exhibit some psycho activity. Thus, they need to be screened further.

Mushroom-Derived Indole Alkaloids

July 19, 2017 / Biology & Ethnobotany, Mushrooms / Psilocybin, Papers / By / ,

Abstract

Mushrooms are known to produce over 140 natural products bearing an indole heterocycle. In this review, the isolation of these mushroom-derived indole alkaloids is discussed, along with their associated biological activities.

First time view on human metabolome changes after a single intake of 3,4 methylenedioxymethamphetamine (MDMA) in healthy placebo-controlled subjects

July 19, 2017 / MDMA, Papers, Psychiatry & Medicine / By / , , , ,

Abstract

3,4-Methylenedioxymethamphetamine (MDMA; “ecstasy”) is widely consumed recreationally. Little is known about its effects on the human metabolome. Mapping biochemical changes after drug exposure can complement traditional approaches by revealing potential biomarkers of organ toxicity or discovering new metabolomic features in a time- and dose-dependent manner. We aimed to analyze for the first time plasma samples from a randomized, double-blind, placebo-controlled crossover study in healthy adults to explore changes in endogenous plasma metabolites following a single intake of MDMA. Plasma samples from 15 subjects taken at four different time points were analyzed with the commercially available AbsoluteIDQ kit (Biocrates). Time series analysis revealed a total of nine metabolites, which showed a significant concentration change after MDMA administration compared with placebo. Paired t tests of the single time points showed statistically significant concentration changes mainly of glycerophospholipids and the metabolic ratio of methionine-sulfoxide over methionine. Changes of this metabolic ratio may be indicative for changes in systemic oxidative stress levels, and the increased amount of glycerophospholipids could be interpreted as an upregulation of energy production. Baseline samples within the experimental study design were crucial for evaluation of metabolomics data as interday individuality within subjects was high otherwise resulting in overestimations of the findings.
