This work examines the anticancer activity, the anti-inflammatory nature, and the cytotoxicity of the ethanol extract obtained from the female flowers of L using molecular methods , animal testing , as well as computational methods and simulations . From the GC-MS analysis, the following bioactive compounds were found: cannabidiol (CBD), tetrahydrocannabinol (THC), and humulene. The antiproliferative activities of the extract were determined on HeLa cells by using MTT, Crystal Violet, and Trypan Blue assays with an IC50 value suggesting 51%-77.6% lethality. The bioinformatics analysis of molecular docking proved significant ligand-protein interactions of CBD, THC, and humulene with cancer-associated proteins such as PD-1/PD-L1, TNF-α, and MMP-9. , breast cancer was first established in female Sprague-Dawley rats with 7,12-dimethylbenz(a)anthracene (DMBA) then treated with cannabinoids either singularly or in combination. Detailed treatment demonstrated that the use of the three cannabinoids simultaneously yielded the best anticancer and anti-inflammatory outcomes together with the best tumor reduction. The concentration of serum biomarkers of inflammation and tumor progression was substantially reduced in treated groups compared to the control group, which proves the synergistic effects of these cannabinoids in breast cancer therapy. This study emphasizes the importance of medical derivatives in cancer treatment.

Prostate cancer has garnered much importance in recent years due to its rising incidence and mortality among men worldwide. The ineffectiveness of existing therapies and adverse events associated with conventional treatment have led patients to turn towards traditional medicine for the management of prostate cancer. Cinnamomum zeylanicum bark essential oil (CZEO) possesses promising anticancer properties, yet the exact mechanism of action of CZEO for the management of prostate cancer remains unclear.

A passive sampler was used to effectively monitor trace volatile organic compound (VOC) concentrations in the atmosphere. VOCs are typically extracted from passive samplers using CS, which is a volatile and hazardous chemical that can leave residues and damage the mass spectrometry (MS) system during gas chromatography (GC)-MS. This study aims to develop and validate alternative solvent extraction methods using acetone, ethanol, n-hexane, and a solution of 99% acetone and 1% CS (ATCS) for VOCs from passive samplers using a standard GC-MS system.
