ACTIVE MOIETY
A new selective radioligand, (11C)SB207145, for positron emission tomography (PET) was used to quantify brain 5-HT4 receptors in sixteen healthy subjects (2045 years, 8 males) using the simplified reference tissue model. Bmax was in accordance with post-mortem brain studies (Spearman's r = 0.83, p = 0.04), and the regional binding potentials, BPND, were on average 2.6 in striatum, 0.42 in prefrontal cortex, and 0.91 in hippocampus. We found no effect of sex but a decreased binding with age (p = 0.046). A power analysis showed that, given the low inter-and intrasubject variation, use of the present method will enable detection of a 15% difference in striatum with only 713 subjects in a 2-sample test and with only 45 subjects in a paired test.
