Title:	Selective serotonin 2A/2C receptor inverse agonists as therapeutics for neurodegenerative diseases
Abstract:	Behavioral pharmacological data with the compound of formula (I), a novel and selective 5HT2A/2C receptor inverse agonist, demonstrate in vivo efficacy in models of psychosis and dyskinesias. This includes activity in reversing MK-801 induced locomotor behaviors, suggesting that this compound may be an efficacious anti-psychotic, and activity in an MPTP primate model of dyskinesias, suggesting efficacy as an anti-dyskinesia agent. These data support the hypothesis that 5HT2A/2C receptor inverse agonism may confer antipsychotic and anti-dyskinetic efficacy in humans, and indicate a use of the compound of formula (I) and related agents as novel therapeutics for Parkinson's Disease, related human neurodegenerative diseases, and psychosis.

Patent Claims:	1. A method of treating Parkinson's Disease psychosis in a patient, comprising administrating to a patient having Parkinson's Disease a therapeutically effective amount of N-(1-methylpiperidin-4-yl)-N-(4-flourophenylmethyl)-N'-(4-(2-methylpropyl- oxy)phenylmethyl)carbamide or a pharmaceutically acceptable salt thereof. 2. A method of treating Parkinson's Disease psychosis in a patient, composing administrating to a patient having Parkinson's Disease a pharmaceutical composition comprising from about 10 mg to about 50 mg of N-(1-methylpiperidin-4-yl)-N-(4-flourophenylmethyl)-N-'-(4-(2-methylpropy- loxy)phenylmethyl)carbamide or a pharmaceutically acceptable salt thereof. 3. Then method of claim 1, wherein about 10 mg of N-(1-methylpiperidin-4-yl)-N-(4-flourophenylmethyl)-N'-(4(2-methylpropylo- xy)phenylmethyl)carbamide of a pharmaceutically acceptable salt thereof is administered. 4. The method of claim 1, wherein about 25 mg of N-(1-methylpiperidin-4-yl)-N-(4-fluorophenylmethyl)-N'-(4-(2-methylpropyl- oxy)phenylmethyl)carbamide or a pharmaceutically acceptable salt thereof is administered. 5. The method of claim 1, wherein about 50 mg of N-(1-methylpiperidin-4-yl)-N-(4-fluorophenylmethyl)-N'-(4-(2-methylpropyl- oxy)phenylmethyl)carbamide or a pharmaceutically acceptable salt thereof is administered. 6. The method of claim 1 or 2, wherein the composition is administered once daily. 7. The method of claim 1, wherein about 0.01 mg/kg of body weight to about 1.5 mg/kg body weight of the compound is administered. 8. The method of claim 1, wherein the tartrate salt of N-(1-methylpiperidin-4-yl)-N-(4-fluorophenylmethyl)-N'-(4-(2-methylpropyl- oxy)phenylmethyl)carbamide is administered. 9. The method of claim 2, wherein the tartrate salt of N-(1-methylpiperidin-4-yl)-N-(4-fluorophenylmethyl)-N'-(4-(2-methylpropyl- oxy)phenylmethyl)carbamide is administered. 10. The method of claim 1, wherein the hydrochloride salt of N-(1-methylpiperidin-4-yl)-N-(4-fluorophenylmethyl)-N'-(4-(2-methylpropyl- oxy)phenylmethyl)carbamide is administered. 11. The method of claim 2, wherein the hydrochloride salt of N-(1-methylpiperidin-4-yl)-N-(4-fluorophenylmethyl)-N'-(4-(2-methylpropyl- oxy)phenylmethyl)carbamide is administered.
