PURPOSE Cannabinoids have been recently proposed as a new family of potential antitumor agents. The present study was undertaken to investigate the expression of the two cannabinoid receptors, CB1 and CB2, in colorectal cancer and to provide new insight into the molecular pathways underlying the apoptotic activity induced by their activation. EXPERIMENTAL DESIGN Cannabinoid receptor expressio...
Several derivatives of cannabinol and the 1,1-dimethylheptyl homolog (DMH) of cannabinol were prepared and assayed for binding to the brain and the peripheral cannabinoid receptors (CB1 and CB2), as well as for activation of CB1- and CB2-mediated inhibition of adenylylcyclase. The DMH derivatives were much more potent than the pentyl (i.e., cannabinol) derivatives. 11-Hydroxycannabinol (4a) was...
Noladin ether (NE) is a putative endogenously occurring cannabinoid demonstrating agonist activity at CB1 receptors. Because of reported selective affinity for CB1 receptors, the pharmacological actions of NE at CB2 receptors have not been examined. Therefore, the purpose of this study was to characterize the binding and functional properties of NE at human CB2 receptors stably expressed in Chi...
Two cannabinoid (CB) receptor subtypes, CB1 and CB2, have been cloned and characterized. Among other activities, receptor activation by cannabinoid ligands may result in pro- or antifibrogenic effects depending on their interaction with CB1 or CB2, respectively. In the current study, we investigated whether selective activation of hepatic CB2 modifies collagen abundance in cirrhotic rats with a...
In light of the adverse side-effects of opioids, cannabinoid receptor agonists may provide an effective alternative for the treatment of cancer pain. This study examined the potency and efficacy of synthetic CB1 and CB2 receptor agonists in a murine model of tumor pain. Intraplantar injection of the CB1 receptor agonist arachidonylcyclopropylamide (ED(50) of 18.4 μg) reduced tumor-related mecha...

Am J Physiol Gastrointest Liver Physiol (November 8, 2012). doi:10.1152/ajpgi.00133.2012 Copyright © 2012 by the American Physiological Society. 2 The endocannabinoid system has been shown to mediate beneficial effects on 25 gastrointestinal inflammation via Cannabinoid receptor 1 (CB1) and 2 (CB2). These 26 receptors have also been reported to activate the MAP-kinases p38...
(-)-Delta9-Tetrahydrocannabinol ((-)-Delta9-THC) is the major active psychotropic component of the marijuana plant, Cannabis sativa. The membrane proteins that have been found to bind this material or its derivatives have been called the cannabinoid receptors. Two GTP-binding protein-coupled cannabinoid receptors have been cloned. CB1 or the neuronal cannabinoid receptor is found mostly in neur...
In the current study, we examined whether ligation of CB2 receptors would lead to induction of apoptosis in tumors of immune origin and whether CB2 agonist could be used to treat such cancers. Exposure of murine tumors EL-4, LSA, and P815 to delta-9-tetrahydrocannabinol (THC) in vitro led to a significant reduction in cell viability and an increase in apoptosis. Exposure of EL-4 tumor cells to ...
