“Background/Objectives: Cannabis sativa has been utilized for medical purposes for thousands of years. It continues to be recognized as a plant with an extensive variety of medicinal and nutraceutical uses today. In this study, a chemical investigation of the flowers of C. sativa isolated by using a variety of chromatographic techniques led to the isolation of eleven compounds. These purified compounds were evaluated for antitumor activity against SK-N-SH neuroblastoma cells.
Methods: The compounds were isolated by using chromatographic techniques. Their structures were identified by the examination of spectroscopic methods, including 1D (1H, 13C, and DEPT) and 2D (COSY, HSQC, HMBC, and NOESY) nuclear magnetic resonance (NMR) spectra and mass spectrum, together with the comparison to those reported previously in the literature. The evaluation of toxicity on SK-N-SH cells was performed by the MTT method.
Results: Eleven compounds were isolated from the flowers of C. sativa, including two new compounds, namely cannabielsoxa (1), 132-hydroxypheophorbide c ethyl ester (2), and six known cannabinoids (6–11), together with the first isolation of chlorin-type compounds: pyropheophorbide A (3), 132-hydroxypheophorbide b ethyl ester (4), and ligulariaphytin A (5) from this plant. The results also demonstrated that cannabinoid compounds had stronger inhibitory effects on neuroblastoma cells than chlorin-type compounds.
Conclusions: The evaluation of the biological activities of compounds showed that compounds 4–10 could be considered as the potential compounds for antitumor effects against neuroblastomas. This is also highlighted by using docking analysis. Additionally, the results of this study also suggest that these compounds have the potential to be developed into antineuroblastoma products.”
