PRIMARY ((11)C)GSK931145 showed good brain penetration and a heterogeneous distribution in agreement with reported GlyT1 localization. Following pretreatment with GSK565710, uptake of ((11)C)GSK931145 was reduced to homogeneous levels. Although ((11)C)GSK565710 also showed good brain penetration and a heterogeneous distribution, the apparent level of specific binding was reduced compared to ((11)C)GSK931145. In contrast, ((11)C)GSK991022 showed a much lower brain penetration and resultant signal following pretreatment with GSK565710. Based on these findings ((11)C)GSK931145 was identified as the most promising ligand for imaging GlyT1 in the porcine brain, possessing good brain penetration, specific signal, and reversible kinetics. ((11)C)GSK931145 is now being progressed into higher species.

ACTIVE MOIETY
We report on (11C)GSK931145 as a novel GlyT-1 imaging probe in primate and man. While the distribution and binding potential values were similar across species, both the plasma free fraction (fP: 0.8 vs. 8%) and delivery (K1: 0.025 vs. 0.126 ml cm23 min21) were significantly lower in humans. Test retest reproducibility in humans calculated using a two tissue compartmental model was poor (VAR(VT): 2938%), but was improved using a pseudo reference tissue model (VAR(BPND): 1623%). GSK1018921 EC50 estimates were 22.5 and 45.7 ng/ml in primates and humans, respectively.
