LY303870 (LY) is a non-peptide neurokinin-1 receptor antagonist that has effects on the brain after peripheral administration. We determined whether LY given by intravenous (iv) injection can cross the blood-brain barrier (BBB). Multiple-time regression analysis showed the unidirectional influx rate (Ki) from blood to brain for LY labeled with tritium to be 6.41+/-0.85 microl/g-min and influx was inhibited by unlabeled LY. HPLC and mass spectrometry showed LY was stable in blood and brain. LY reached a brain/serum ratio of 190+/-12 microl/g with about 0.07% of the injected dose entering each gram of brain. These results show that LY is transported across the BBB from serum into brain by a saturable system.
