AZD0530 in human cerebrospinal fluid at different doses. (A) Each point represents fasting trough cerebrospinal fluid (CSF) AZD0530 level from a different human subject for the left three columns. The mouse trough CSF values are derived from brain levels at the 5 mg/kg per day dose that rescued memory deficits . **
P < 0.001, one-way analysis of variance with Tukey post-hoc comparisons. (B) Relationship between CSF and plasma AZD0530 levels. Each point is from a different individual, and different dose groups are illustrated with different colors. There is a tight correlation of plasma and CSF level as indicated (R2 = 0.97, Pearson correlation coefficient). Bars represent mean ± standard error of the mean. n.s, Not significant.
