receptor antagonist (pIC50
= 7.4 for chimeric OX2
values are 5.9 and 8.5 for OX1
receptors respectively). Shows no significant activity in a panel of over 50 other neurotransmitters and neuropeptide receptors. Achieves high level of OX2
receptor occupancy in the rat brain; exhibits sleep-promoting effects in rats.
