Comparison of the protective capacities of CB86 and CB204 in prevention of mitochondrial membrane potential depolarization. FACS was used to evaluate the Δψm depolarization in (A) Control group, (B) cells pretreated with CB86 alone, (C) cells pretreated with CB204 alone, (D) cells exposed to 0.5 mM of CoCl2, (E) cells pretreated with CB86 and exposed to CoCl2, (F) cells pretreated with CB204 and exposed to CoCl2, (G) positive control group exposed to CCCP, and (H) representative bar graph of the raw data. Results are expressed as mean ± SEM (n = 7 replicates in each group). ### and *** p < 0.001.
