FIG. 3.

Synthetic cannabinoid compounds reduce the viability of CRC cell lines. Cell viability was assessed with MTS assay 48 h after treatment with selected cannabinoid compounds at a concentration of 10 μM: (A) 5-epi CP 55,940, (B) HU-331, (C) PTI-1, (D) 3-epi CP 47,497 C-8 homolog, (E) CBD, and (F) THC. The DMSO control bar is included as a general reference as viability for each of the cell lines was normalized to its own vehicle (DMSO) treatment (conducted in triplicate). Error bars are SEM; *p≤0.05, **p≤0.01, ***p≤0.001.
