quinone/cannabis

Several quinones have been found to be effective in the treatment of some forms of cancer; however, their cumulative heart toxicity limits their use. The cannabinoid quinone HU-331 [3S,4R-p-benzoquinone-3-hydroxy-2-p-mentha-(1,8)-dien-3-yl-5-pentyl] is highly effective against tumor xenografts in

Chromenopyrazolediones have been designed and synthesized as anticancer agents using the multi-biological target concept that involves quinone cytotoxicity and cannabinoid antitumor properties. In cell cytotoxicity assays, these chromenopyrazolediones have antiproliferative activity against human

Recent findings on the inhibition of angiogenesis and vascular endothelial cell proliferation by anthracycline antibiotics, which contain a quinone moiety, make this type of compound a very promising lead in cancer research/therapy. We have reported that a new cannabinoid anticancer quinone,

The oxidation of cannabis constituents has given rise to their corresponding quinones, which have been identified as cytotoxic agents. Out of these molecules the quinone of cannabidiol--the most abundant non-psychoactive cannabinoid in Cannabis sativa--has shown the highest cytotoxicity. This

Triple-negative breast cancer (TNBC) represents a subtype of breast cancer characterized by high aggressiveness. There is no current targeted therapy for these patients whose prognosis, as a group, is very poor. Here, we report the synthesis and evaluation of a potent antitumor agent in vivo for

The main psychoactive constituent of marijuana, (-)-Delta(9)-tetrahydrocannabinol, produces most of its physiological effects by interacting with the CB1 cannabinoid receptor, a membrane protein belonging to the large superfamily of G-protein coupled receptors. The 3-D structure of the receptor

Photooxygenation of Δ8 tetrahydrocannabinol (Δ8-THC), Δ9 tetrahydrocannabinol (Δ9-THC), Δ9 tetrahydrocannabinolic acid (Δ9-THCA) and some derivatives (acetate, tosylate and methyl ether) yielded 24 oxygenated derivatives, 18 of which were new and 6 were previously reported, including allyl alcohols,

Three cannabis constituents, cannabidiol (1), Delta(8)-tetrahydrocannabinol (3), and cannabinol (5), were oxidized to their respective para-quinones 2, 4, and 6. In the 1960s, the oxidized product 4 had been assigned a para-quinone structure, which was later modified to an ortho-quinone. To

Recently, it has been estimated that nearly 200 million people use marijuana with growing usage being attributed to the legalization and decriminalization of the drug around the world. A concerning implication of increased marijuana use is the alarming number of individuals who report driving under

The activation of the transcription factor Nrf2 inhibits neuropathy and modulates the activity of delta-opioid receptors (DOR) in type 2 diabetic mice but the impact of Nrf2/HO-1 pathway on the antinociceptive actions of cannabinoid 2 receptors (CB2R) has not been assessed. Using male mice

Anthracyclines, a large group of quinonoid compounds, are used to treat some forms of cancer. Although highly effective in cancer therapy, the mechanism of action of these compounds is not specific; they act on cancer and other cells by numerous mechanisms. A new anticancer quinone (HU-331) was

Prostate cancer is a major cause of death among men worldwide. Recent preclinical evidence implicates cannabinoids as powerful regulators of cell growth and differentiation, as well as potential anti-cancer agents. The aim of this review was to evaluate the effect of cannabinoids on in vivo prostate

The analgesic and anti-hyperalgesic effects of cannabinoid- and vanilloid-like compounds, plus the fatty acid amide hydrolase (FAAH) inhibitor Cyclohexylcarbamic acid 3'-carbamoyl-biphenyl-3-yl ester (URB597), and acetaminophen, were evaluated in the phenyl-p-quinone (PPQ) pain model, using
