ACTIVE MOIETY
Originator: Merz Pharma; Mechanism of Action: Dopamine uptake inhibitor; Orphan Drug Status: No; On Fast track: No; New Molecular Entity: Yes; Highest Development Phase: Phase I for Fatigue Most Recent Event: 08 Jun 2014 Phase-I clinical trials in Fatigue (In volunteers) in Germany (unspecified route)
ACTIVE MOIETY
At the doses 25-100 mg/kg i.p. the drug induced dose-dependent ipsilateral rotations in rats with unilateral 6-hydroxydopamine (6-OHDA)-induced nigrostriatal system lesions. However, MRZ-9547 enhanced contralateral rotation produced by L-DOPA given at an effective (25 mg/kg i.p.), but not at a sub-effective (6.25 mg/kg i.p.) dose. Microdialysis experiments revealed that MRZ-9547 penetrated well to the brain and did not show any pharmacokinetic interaction with L-DOPA. In unilaterally 6-OHDA-lesioned rats having developed abnormal involuntary movements (AIMs, a rodent correlate of LID) after chronic L-DOPA treatment, MRZ-9547 (50 mg/kg i.p.) did not significantly affect the AIMs expression. The results indicate that MRZ-9547 may by itself have antiparkinsonian activity at early stages of the disease, when some dopaminergic terminals are still intact. It may also enhance antiparkinsonian effect of L-DOPA. MRZ-9547 does not seem to influence the expression of LID in 6-OHDA-lesioned rats. The results support the use of MRZ-9547 in PD patients treated with L-DOPA.
ACTIVE MOIETY
Results reveal that MRZ-9547 is a selective dopamine transporter (DAT) inhibitor that moderately stimulated striatal dopamine release. MRZ-9546 was a much less potent DAT inhibitor. Furthermore, MRZ-9547 dose dependently increased the tendency to work for food reinforcement both in the standard PR task and the PR/chow feeding choice task, MRZ-9546 was considerably less active. Relative to MRZ-9547, other DAT-interfering drugs had only moderate (methylphenidate) or marginal (modafinil, d-amphetamine) stimulant effects on PR responding in either task. Collectively, our data demonstrate that the DAT inhibitor MRZ-9547 can markedly stimulate PR responding and shift effort-related decision making in intact rats towards high-effort response options. An analysis of effort-related decision making in rodents could provide an animal model for motivational dysfunctions related to effort expenditure such as fatigue, e.g. in Parkinson's disease or major depression.
