“Delta-9 tetrahydrocannabinol (Delta(9)-THC) and (-)-cannabidiol ((-)-CBD) are major constituents of the Cannabis sativa plant with different pharmacological profiles…
We tested a series of (+)- and (-)-CBD derivatives for central and peripheral effects in mice…
We suggest that (+)-CBD analogues have mixed agonist/antagonist activity in the brain.
Second, (-)-CBD analogues which are devoid of cannabinoid receptor affinity but which inhibit intestinal motility, suggest the existence of a non-CB(1), non-CB(2) receptor.
Therefore, such analogues should be further developed as antidiarrheal and/or antiinflammatory drugs.
We propose to study the therapeutic potential of (-)- and (+)-CBD derivatives for complex conditions such as inflammatory bowel disease and cystic fibrosis.”
