In Vitro and In Vivo Anti-Inflammatory Potential of Cannabichromene Isolated from Hemp

/by

Cannabichromene (CBC), a non-psychoactive cannabinoid found in Cannabis sativa, has recently been shown to possess several medicinal properties. However, how CBC produces anti-inflammatory effects and the mechanisms of this remain poorly studied. Therefore, we extracted and purified the CBC from the Cannabis sativa cv. pink pepper (hemp cultivar). The efficacy of CBC in reducing inflammation in RAW 264.7 macrophages and a λ-carrageenan-induced mouse model was then evaluated. CBC had no cytotoxicity up to a concentration of 20 μM and inhibited nitric oxide production by approximately 50% at a concentration of 20 μM.

Is it the Ideal Time to Start Prescribing Cannabis Derivatives to Treat Endometriosis-associated Pain?

/by

Endometriosis affects 5%-10% of women of reproductive age and is often associated with painful symptoms like dysmenorrhea, dyschezia, dyspareunia, and even non cyclical pain. The disease is diagnosed in at least 20% of women with dysmenorrhea and/or non-menstrual pelvic pain, reaching a prevalence of 50% pain among adolescents. There is an alignment among international societies3,4 that the pre- sumed diagnosis of this disease is enough to start clinical treatment. Moreover, there seems to be a consensus that first-line treatment should be hormonal contraceptives since the efficacy is similar to that of surgery but with lower complication rates and costs. However, these drugs are
effective in only approximately two-thirds of patients, have limited long-term efficacy and may occasionally lead to undesirable side effects. Additionally, there are serious limitations in the interpretation of clinical trials.

Anticancer properties of cannabidiol and Δ9-tetrahydrocannabinol and synergistic effects with gemcitabine and cisplatin in bladder cancer cell lines

/by

With the legalization of cannabis in multiple jurisdictions throughout the world, a larger proportion of the population consumes cannabis. Several studies have demonstrated anti-tumor effects of components present in cannabis in different models. Unfortunately, little is known about the potential anti-tumoral effects of cannabinoids in bladder cancer, and how cannabinoids could potentially synergize with chemotherapeutic agents. Our study aims to identify whether a combination of cannabinoids, like cannabidiol and Δ9-tetrahydrocannabinol with agents commonly used to treat bladder cancer, such as gemcitabine and cisplatin, is able to produce desirable synergistic effects. We also evaluated whether co-treatment of different cannabinoids also generated synergistic effects.

Phytocannabinoids: Origins and Biosynthesis

/by

hytocannabinoids are bioactive terpenoids that were thought to be exclusive to Cannabis sativa, but have now also been discovered in Rhododendron species, some legumes, the liverwort genus Radula, and some fungi.

Many cannabinoids display promising non-hallucinogenic bioactivities that are determined by the variable nature of the side chain and prenyl group defined by the enzymes involved in their synthesis.
