Development and Validation of an Ultra-Fast and Sensitive Microflow
Drug Testing Research article and Analysis Received: 6 June 2016 Revised: 9 July 2016 Accepted: 10 July 2016 Published online in Wiley Online Library: 10 August 2016 (www.drugtestinganalysis.com) DOI 10.1002/dta.2042 Development and validation of an ultra-fast and sensitive microflow liquid chromatography- tandem mass spectrometry (MFLC-MS/MS) method for quantification of LSD and its metabolites in plasma and application to a controlled LSD administration study in humans Andrea E. Steuer,a* Michael Poetzsch,a Lorena Stock,a Lisa Eisenbeiss,a Yasmin Schmid,b Matthias E. Liechtib and Thomas Kraemera Lysergic acid diethylamide (LSD) is a semi-synthetic hallucinogen that has gained popularity as a recreational drug and has been investigated as an adjunct to psychotherapy. Analysis of LSD represents a major challenge in forensic toxicology due to its insta- bility, low drug concentrations, and short detection windows in biological samples. A new, fast, and sensitive microflow liquid chromatography (MFLC) tandem mass spectrometry method for the validated quantification of LSD, iso-LSD, 2-oxo 3-hydroxy- LSD (oxo-HO-LSD), and N-desmethyl-LSD (nor-LSD) was developed in plasma and applied to a controlled pharmacokinetic (PK) study in humans to test whether LSD metabolites would offer for longer detection windows. Five hundred microlitres of plasma were extracted by solid phase extraction. Analysis was performed on a Sciex Eksigent MFLC system coupled to a Sciex 5500 QTrap. The method was validated according to (inter)-national guidelines. MFLC allowed for separation of the mentioned analytes within 3 minutes and limits of quantification of 0.01 ng/mL. -

Email: [email protected] Received: 01 March 2016, Revised and Accepted: 29 January 2018 ABSTRACT Plants in the genus Tabernaemontana have been using in Thai and Chinese traditional medicine for the treatment several diseases. The great majority constituents of Tabernaemontana species have already been subjected to isolation and identification of monoterpene indole alkaloids present in their several parts. Many of monoterpene indole alkaloids exhibited a wide array of several activities. The biogenesis, classification, and biological activities of these alkaloids which found in Tabernaemontana plants were discussed in this review and its brings the research up-to-date on the bioactive compounds produced by Tabernaemontana species, directly or indirectly related to human health.

The aim of the present study was to investigate the chemical stability of cannabidiol (CBD) in the form of a solid powder (hereinafter referred to as CBD powder) and also dissolved in sunflower oil. We performed stress studies in accordance with the International Conference on Harmonization (ICH) guidelines, where 5 mg of marketed CBD in the form of a solid powder and in form of oil solution were exposed for 7 and 14, 30, 60, 90, 180, 270, and 365 days to precisely defined temperature and humidity conditions, 25 ◦C ± 2 ◦C/60% RH ± 5% and 40 ◦C ± 2 ◦C/75% RH ± 5% in both open and closed vials in the dark. CBD powder was significantly more stable than CBD in oil solution. Such finding is important because CBD is often administered dissolved in oil matrix in practice due to Citation: Kosovi´c,E.; Sýkora, D.; very good bioavailability. -

The capsules were clear, hard gelatin, standard shape size No. o. Average weight was 114 milligrams. Each capsule had a white crystalline coating on inner surface of capsule body. Apparently a measu~ed amount of solution had been placedin the cap·sule body, after which it was rotated to spread the solution on the inner surface. The substance contained 8. 7 milli grams STP (DOM)HCl per ca·psule. · These were the first STP capsules of this type seen by our laboratory. A few years ago, capsules were ob tained in the U.S. similarly coated with LSD. STP (Free Base) on laboratory filter paper, also from Germany, was seen for the first time in our laboratory. The STP spots, containing approxi mately 8 miliigrams STP base each, were 5/8 to 3/4 inch in diameter. The paper was 1\ inches square. Phencyclidine (Free Base) was recently analyzed on parsley leaves. Called "Angel DUst, 11 the phencyclidine on two samples of leaves was 2.6% and 3.6%. Approximately thirty pounds of 94% pure powder was also analyzed. (For identification of phencyclidine base, see Microgram, II, 1, p.3 (Jan 1969). IMITATIONSof well-known drug products are examined frequently in our Special Testing and Research Laboratory. Many of these are well made preparations and closely resemble the imitated product. -
Endocannabinoid Stimulated Release of Nitric Oxide and Its Mitochondrial
A tica nal eu yt c ic a a m A r a c t Stefano et al., Pharm Anal Acta 2015, 6:6 h a P Pharmaceutica Analytica Acta DOI: 10.4172/2153-2435.1000378 ISSN: 2153-2435 Review Article Open Access Endocannabinoid Stimulated Release of Nitric Oxide and its Mitochondrial Influence Triggering Vascular Pathology George B Stefano*, Erin Quinn and Richard M Kream MitoGenetics LLC, 3 Bioscience Park Drive, Suite 307, Farmingdale, NY 11735, USA Abstract Endocannabinoids, and their respective receptors, are involved in a host of cellular regulatory activities. In part, some of these mediated effects occur by way of stimulating constitutive nitric oxide release. This occurs in endothelia, certain white blood cells, microglia, and in similar invertebrate tissues, demonstrating that this is a conserved chemical messenger system. This endocannabinoid chemical messenger system, coupled to constitutive nitric oxide release, also appears to exert regulatory effects on mitochondrial energy associated processes, further substantiating its primordial history. In this regard, it appears to offer some beneficial actions in the occurrence of reperfusion injury and stroke. The mechanism envisioned is one initiated via a hypoxic event, which does not restore normalcy, then progresses to a pro-inflammatory state, and the resultant chronic condition manifests itself in a specific disorder. This fits nicely into a vascular-associated origin for Alzheimer’s Disease, whereby the pro- inflammatory state encompasses vessels that have endothelial gaps, providing for a compromised blood brain barrier, beta amyloid deposition, and enhanced white blood cell trafficking. In time, due to the physical progression of the events, Alzheimer’s Disease occurs. -
