Cannabis-derived substances in cancer therapy–an emerging anti-inflammatory role for the cannabinoids.

“Cannabinoids, the active components of the cannabis plant, have some clinical merit both as an anti-emetic and appetite stimulant in cachexic patients. Recently, interest in developing cannabinoids as therapies has increased following reports that they possess anti-tumour properties.

 Research into cannabinoids as anti-cancer agents is in its infancy, and has mainly focussed on the pro-apoptotic effects of this class of agent. Impressive anti-cancer activities have been reported; actions that are mediated in large part by disruptions to ubiquitous signalling pathways such as ERK and PI3-K. However, recent developments have highlighted a putative role for cannabinoids as anti-inflammatory agents. Chronic inflammation has been associated with neoplasia for sometime, and as a consequence, reducing inflammation as a way of impacting cancer presents a new role for these compounds.

 This article reviews the ever-changing relationship between cannabinoids and cancer, and updates our understanding of this class of agent. Furthermore, the relationship between chronic inflammation and cancer, and how cannabinoids can impact this relationship will be described.”

Abstract

“There are at least two types of cannabinoid receptors, CB1 also named CNR1 and CB2 also named CNR2, both coupled to G proteins. CB1 receptors exist primarily on central and peripheral neurons. CB2 receptors are present mainly on immune cells. Endogenous agonists for cannabinoid receptors (endocannabinoids) have also been discovered, the most important being arachidonoyl ethanolamide (anandamide), 2-arachidonoyl glycerol (2-AG), and 2-archidonyl glyceryl ether. Following their release, endocannabinoids are removed from the extracellular space and then degraded by intracellular enzymic hydrolysis. CB1/CB2 agonists are already used clinically as antiemetic or to stimulate appetite. Potential therapeutic uses of cannabinoid receptor agonists include the management of multiple sclerosis, spinal cord injury, pain, inflammatory disorders, glaucoma, bronchial asthma, vasodilatation that accompanies advanced cirrhosis, and cancer.”
