- Cannabis. X. The isolation and structures of four new propyl cannabinoid acids, tetrahydrocannabivarinic acid, cannabidivarinic acid, cannabichromevarinic acid and cannabigerovarinic acid, from Thai cannabis, Meao Variant
-
Four new cannabinoids acids, tetrahydrocannabivarinic acid, cannabidivarinic acid, cannabichromevarinic acid and cannabigerovarinic acid were isolated from Thai Cannabis 'Meao variant' and these structures were elucidated on the basis of chemical and spectral data. This is the first example of the isolation of propyl cannabinoid acid from Cannabis.

- A Novel and Practical Continuous Flow Chemical Synthesis of Cannabidiol (CBD) and its CBDV and CBDB Analogues
-
Cannabidiol is one of the main non-psychoactive cannabinoids present in Cannabis sativa and, in the last decade, it is gaining great interest among the scientific community for its pharmaceutical, nutraceutical, and cosmetic applications. Herein, we report the first continuous flow chemical synthesis of cannabidiol (CBD) and its analogues cannabidivarin (CBDV) and cannabidibutol (CBDB). This approach permits to synthesize products in very good yields (55–59 %), limiting the formation of psychoactive and illegal cannabinoids such as tetrahydrocannabinol (THC).

- Design of Negative and Positive Allosteric Modulators of the Cannabinoid CB2Receptor Derived from the Natural Product Cannabidiol
-
Cannabidiol (CBD), the second most abundant of the active compounds found in the Cannabis sativa plant, is of increasing interest because it is approved for human use and is neither euphorizing nor addictive. Here, we design and synthesize novel compounds taking into account that CBD is both a partial agonist, when it binds to the orthosteric site, and a negative allosteric modulator, when it binds to the allosteric site of the cannabinoid CB2 receptor. Molecular dynamic simulations and site-directed mutagenesis studies have identified the allosteric site near the receptor entrance. This knowledge has permitted to perform structure-guided design of negative and positive allosteric modulators of the CB2 receptor with potential therapeutic utility.

- Synthesis of CBD and Its Derivatives Bearing Various C4′-Side Chains with a Late-Stage Diversification Method
-
A novel synthetic route for making (-)-CBD and its derivatives bearing various C4′-side chains is developed by a late-stage diversification method. Starting from commercially available phloroglucinol, the key intermediate (-)-CBD-2OPiv-OTf is efficiently and regioselectively prepared and further undergoes Negishi cross-coupling to furnish (-)-CBD. This approach allowed an efficient synthesis of (-)-CBD in a five-step total 52% yield on a 10 g scale. Furthermore, diversification on the C4′-side chain with this method can be realized in a wide range.
