Abstrakt: The comprehensive anti-cancer activities of cannabinoid acids and non-cannabinoids are not fully explored. Herein we report simple extraction, faster bioassay-guided fractionation, and HPLC-assisted purification of bioactive secondary metabolite and their identification. Anti-proliferative activity of six cannabinoid acids and eleven non-cannabinoids from the leaves of Cannabis sativa was evaluated. HPLC- assisted purification from the bioactive fractions leads to isolate one new compound Methoxy Canniprene (methoxy isoprenyl bibenzyl), including all six CBDA's eleven non-cannabinoids in a single step, and NMR, HR-ESI-MS studies, and comparison with the literature data authenticated their structures. The crude extract (IC50 range: 18.0–37.2 μg/mL), Fraction A to D (11.9–222 μg/mL), and purified different cannabinoid and non cannabinoids (IC50 range: 0.5–100 μM) displayed potent anti-proliferative activities against almost all the tested five human cancer cell lines. Computational analysis based on molecular docking studies and absolute binding free energy calculation have identified targets for various cancer-associated proteins, including Aldehyde dehydrogenase 1 A1, Topoisomerase I, GSK-3 Beta, Protein Kinase C beta II, and Neurotrophic Tyrosine Kinase receptor type 1.
