Cannabinoid receptor activation correlates with the pro-apoptotic action of the β2-adrenergic agonist, (R,R’)-4-methoxy-1-naphthylfenoterol, in HepG2 hepatocarcinoma cells

“In the last several years, development of new CBR ligands has become an intense area in cancer research because of the role of the endocannabinoid system in the regulation of cell proliferation and apoptosis…

The therapeutic potential for synthetic small bivalent ligands holds great promise as new lead compounds in a wide range of disparate diseases.”

Anti-tumoral action of cannabinoids on hepatocellular carcinoma: role of AMPK-dependent activation of autophagy

“Hepatocellular carcinoma (HCC) is the third cause of cancer-related death worldwide… few therapeutic options are available… we investigated the effects of cannabinoids–a novel family of potential anticancer agents–on the growth of HCC. We found that Δ(9)-tetrahydrocannabinol (Δ(9)-THC, the main active component of Cannabis sativa)… reduced the viability of the human HCC cell lines…cannabinoids were also able to inhibit tumor growth… Our findings may contribute to the design of new therapeutic strategies for the management of HCC.”
