TABLE I.

Composition of radioactivity in rat brain and plasma after injection of [¹¹C]MNPA

Samples	Radiochemical species	Condition
Samples	Radiochemical species	Baseline (%)	Depletion (%)
Brain	[¹¹C]MNPA	89.6 ± 0.9	92.0 ± 1.2
	Radiometabolites	10.4 ± 1.7	8.0 ± 1.8
Plasma	[¹¹C]MNPA	28.6 ± 21.6	38.7 ± 18.2
	Radiometabolites	71.4 ± 16.4	61.3 ± 19.3

Rats were euthanized 30 min after injection of [¹¹C]MNPA, and radioactivity was extracted from brain and plasma. Values are average ± SD of radioHPLC analyses (n = 4 in each condition).
