Comparing compounds 28 and 28a–e to the groups of mice given scopolamine, the compounds showed different effects on swim speed (a), escape latency (b), platform crossing time (c), and TSTQ (d). Values are presented as Mean ± SD, with n = 6. ^####p < 0.0001 compares the positive control to the normal control; ****p < 0.0001 compares the treatment groups to the positive control; ***p < 0.001 compares the treatment groups to the positive control; **p < 0.01 compares the treatment groups to the positive control; *p < 0.01 compares the treatment groups to the positive control
