Silicon-based Tetrahydrocannabinol Derivatives and Compositions Thereof

open access: yes, 2022
Silicon-based tetrahydrocannabinol derivatives and methods for their synthesis are provided, in which the derivatives contain a tetrahydrocannabinol molecule and at least one silicon-based group containing Si--O--Si bonds.

The tetrahydrocannabinol and tetrahydrocannabinolic acid content of cannabis products

open access: yesJournal of Pharmacy and Pharmacology, 1981
Abstract Cannabinoid acids readily decarboxylate to the corresponding cannabinoid. Methods are available for the determination of Δ9-tetrahydrocannabinol (THC) and its acids (THCA) and published data on the levels of these compounds in cannabis are summarized.

Investigating the cumulative effects of Δ9-tetrahydrocannabinol and repetitive mild traumatic brain injury on adolescent rats [PDF]

open access: yes, 2020
The prevalence of mild traumatic brain injury is highest amongst the adolescent population and can lead to complications including neuroinflammation and excitotoxicity. Also pervasive in adolescents is recreational cannabis use.

Screening microbially produced Δ9-tetrahydrocannabinol using a yeast biosensor workflow. [PDF]

open access: yes, 2022
Microbial production of cannabinoids promises to provide a consistent, cheaper, and more sustainable supply of these important therapeutic molecules. However, scaling production to compete with traditional plant-based sources is challenging.

Hippocampal differential expression underlying the neuroprotective effect of delta-9-tetrahydrocannabinol microdose on old mice

open access: yesFrontiers in Neuroscience, 2023
Delta-9-tetrahydrocannabinol (THC) is the primary psychoactive compound of the cannabis plant and an exogenous ligand of the endocannabinoid system. In previous studies, we demonstrated that a single microdose of THC (0.002 mg/kg, 3–4 orders of magnitude

The Diels‐Alder Approach towards Cannabinoid Derivatives and Formal Synthesis of Tetrahydrocannabinol (THC) [PDF]

open access: yes, 2021
Based on the Diels-Alder reaction of vinylchromenes with electron-poor dienophiles, we developed a strategy for the synthesis of tetrahydrocannabinol derivatives.

Effect of harvest time on the compositional changes in essential oils, cannabinoids, and waxes of hemp (Cannabis sativa L.)

open access: yesRoyal Society Open Science, 2022
Demand for cannabinoid is growing, with the global market expected to reach $9.69 billion by 2025. Understanding how chemical composition changes in hemp at different harvest times is crucial to maximizing this industrial crop value.

Determination of the Cross-Reactivity of the Biological Metabolite (-)-trans-Δ9-Tetrahydrocannabinol-Carboxylic Acid-Glucuronide (THC-COOH-Gluc) for Cannabinoid Immunoassays. [PDF]

open access: yes, 2021
The highest concentrated metabolite of (-)-trans-Δ9-tetrahydrocannabinol (THC) in urine, the main psychoactive constituent of Cannabis sativa, is 11-nor-9-carboxy-(-)-trans-Δ9-tetrahydrocannabinol-β-D-glucuronide [(-)-trans-THC-COOH-Gluc].

Isothiazologuanosine (tzG) as Environmentally Sensitive Fluorescent Reporter in RNA

open access: yesAngewandte Chemie, EarlyView.
The emissive isothiazologuanosine analog tzG is synthesized for the first time as RNA phosphoramidite building block for solid‐phase synthesis. Due to its isomorphic and isofunctional characteristics, tzG forms Watson–Crick base pairs and can be used as fluorescent probe to monitor (deoxy)ribozyme activity.
