  • Publication number: 20130197032
    Abstract: The present invention relates to a novel use of both enantiomers of the phenylpiperidine derivative OSU6162, i.e. (?) and (+)-OSU6162 as partial agonists on 5-hydroxytryptamine (5hHT) receptors. As a result, both (?) OSU6162 and (+)-OSU6162 may be used for the treatment and/or prevention of one or more diseases associated with a need for modulation of monoaminergic neurotransmitter receptors, wherein at least one of the monoaminergic neurotransmitter receptors is a 5-hydroxytryptamine receptor (5-HT receptor). Thus, said compounds act as stabilizers not only on dopaminergic, but also on serotonergic brain signaling and will act as partial agonists on such monoaminergic neurotransmitter receptors.
