FIGURE 6.
KOPr agonists cause motor incoordination in the rotarod performance assay. Using a rotarod apparatus set to accelerate from 4 to 40 rpm over 300 s, SalA showed a significant effect at 15–30 min. (A) 16-Ethynyl showed a significant effect at 15–30 min. (B) 16-Bromo SalA had a significant impairment at 15–30 min at 1 mg/kg. Two-way repeated-measures ANOVA, **p < 0.01, ****p < 0.0001 for 2 mg/kg dose (above) or SalA (below) vs. vehicle. #p < 0.05, ###p < 0.001 for 1 mg/kg dose vs. vehicle. ∧indicates time point where SalA is more sedative than both doses of the novel analog. Values presented as mean ± SEM, n = 6.
