I used to be lucky to cross paths with Raphael Mechoulam, “the daddy of hashish analysis,” at a number of science conferences over time. Probably the most memorable event was the twenty second annual assembly of the Worldwide Cannabinoid Analysis Society (ICRS) in Freiburg, Germany, in July 2012. Mechoulam delivered a plenary speech on the symposium, addressing the way forward for cannabinoid analysis and key areas of examine that needs to be pursued.
It was precisely fifty years earlier, in 1962, when Mechoulam launched his scientific investigation into the chemistry of hashish. In 1963, he and Yuval Shvo first reported the molecular construction of cannabidiol (CBD). And the next 12 months Mechoulam coauthored a paper that elucidated the molecular construction of tetrahydrocannabinol (THC). Though he didn’t understand it on the time, Mechoulam had lit a gradual burning fuse that will detonate a revolution in medical science.
As a younger scientist, Mechoulam got down to perceive how hashish works; he ended up unlocking a treasure trove of details about how we work. Recognized affectionately as “Raphi” to most of the scientists he mentored, Mechoulam tirelessly promoted cooperation between researchers around the globe to advance the examine of the physique’s “endocannabinoid system,” which produces chemical compounds just like THC, CBD, and different plant cannabinoids, and mediates their results.
In 1992, Mechoulam’s analysis group at Hebrew College in Jerusalem found an endogenous THC-like compound that prompts receptors within the mammalian mind. He named it “anandamide,” the bliss molecule. And in 1995, Mechoulam and his workforce recognized a second endocannabinoid compound, 2-arachidonoyglycerol or 2-AG for brief. Anandamide and 2-AG are a part of an inside lipid neurotransmitter system that regulates a variety of physiological processes, together with urge for food, temper, ache notion, and immune operate.
“Planning Analysis for the Subsequent Half Century”
“It’s time to plan forward for the subsequent half a century,” Mechoulam, age 81, informed the Freiburg ICRS attendees, who had gathered to honor his 50 years as a pioneer hashish scientist. Mechoulam cited three particular areas that needs to be analysis priorities: CBD, the CB2 cannabinoid receptor, and a cluster of endogenous fatty acid compounds within the mind that he known as FAAA’s.

Needless to say this was in 2012, when CBD was just about unknown to most of the people. Nevertheless it was already a scorching matter amongst ICRS scientists who have been probing the compound’s anti-inflammatory, antioxidant, anticonvulsant, anti-tumoral, neuroprotective, and analgesic properties. The preclinical science was actually jaw-dropping, and Mechoulam envisioned a big selection of therapeutic functions for CBD and its derivatives. However medical research of plant cannabinoids have been lagging due to strict drug legal guidelines in the US and elsewhere.
THC instantly prompts each cannabinoid receptor subtypes – CB1 and CB2. Nonetheless, when THC binds to CB2, it doesn’t set off the psychoactive excessive that hashish is thought for as a result of CB2 receptors will not be concentrated within the mind. THC binding to CB1, the considerable central nervous system receptor, causes the intoxicating impact. Consequently, researchers set their sights on therapeutic with out the excessive by experimenting with medicine that stimulate the CB2 receptor – whereas bypassing CB1 within the mind.
CB2 receptors are current all through the immune system, the peripheral nervous system, metabolic tissue, pores and skin cells, and in lots of inside organs. Aberrant CB2 signaling is implicated in a raft of autoimmune, neurodegenerative, metabolic, and psychiatric problems. This makes modulating CB2 a gorgeous goal for drug improvement and therapeutic intervention.
A Cluster of FAAA’s
Mechoulam was notably excited concerning the third space of analysis – the FAAA’s – which comprise a cluster of fatty acid compounds within the mind. Little is thought about “the chemistry of the human persona” or the innate biochemical variations that that will account for particular person variations in temperament, he defined, including: “Accumulation of such data is crucial for a future biochemical foundation of psychology.”
If particular chemical variations “are the trigger, or one of many causes, of the variations in personalities,” then it’s important “to search for a big ‘catalog’ of compounds, which trigger central nervous system results,” Mechoulam asserted. “The variability of such a cluster of compounds – their ranges, their ratios and presumably their results, not solely as particular person compounds, but in addition as a gaggle” (a sort of entourage impact) might lead to “an infinite variety of particular person variations.”

Mechoulam drew consideration to the significance of a number of dozen endocannabinoid-like lipids and different FAAA’s, which embody varied fatty acid amides of amino acids (and their derivatives, comparable to ethanol amides) or fatty acid esters with glycerol and associated compounds. A partial checklist of those compounds had been recognized and analyzed by Heather Bradshaw’s group on the College of Indiana. A few of these compounds have been “evaluated for his or her organic results,” Mechoulam famous. “Amongst them are anandamide, 2-AG, NADA, palmitoyl ethanolamide (PEA), oleoyl ethanolamide (OEA), stearoyl ethanolamide, and some others,” whose particular person results range significantly, however “the joint results of teams of those elements … haven’t been evaluated.”
Mechoulam and his colleagues regarded carefully at “oleoyl serine,” which is anti-osteoporotic, however can also be discovered within the mind. “Arachidonoyl serine,” one other endogenous lipid compound of curiosity, “lowers injury attributable to closed head damage.” And he noticed that “oleoyl glycine” and PEA concentrations are enhanced after injury in a selected mind area. These research gave rise to the idea of the “endocannabinoidome” – an expanded endocannabinoid system that encompasses a plethora of fatty acid neurotransmitters along with anandamide and 2-AG.
“It’s tempting to imagine,” Mechoulam concluded, “that the large doable variability of the degrees and ratios of drugs in such a cluster of compounds could permit an infinite variety of particular person variations, the uncooked substance which in fact is sculpted by expertise. If this mental hypothesis is proven to have some factual foundation it could result in main advances in molecular psychology.”
