The Uses of cycrimine

Cycrimine is a cholinolytic anti-Parkinson drug which can cause neuromuscular blockades in isolated rat diaphragms.

Indications

For treatment and management of Parkinson's disease.

Background

Cycrimine is a drug used to reduce levels of acetylcholine to return a balance with dopamine in the treatment and management of Parkinson's disease.

Definition

ChEBI: A member of the class of piperidines that is 3-(piperidin-1-yl)propan-1-ol in which one of the hydrogen atoms at the 1-position is substituted by cyclopentyl, and the other is substituted by phenyl. A central anticholinergic, it is used as its hydrochlorid salt in the management and treatment of Parkinson's disease.

Manufacturing Process

The manufacture of the cyclohexyl analog is as follows. Phenyl magnesium bromide was prepared from 48.5 g (0.308 mol) of bromobenzene, 7 g (0.29 mol) of magnesium, and 125 ml of dry ether. To it was added at 5°C over a period of ? hour 40 g (0.18 mol) of cyclohexyl β-(N-piperidyl)-ethyl ketone (BP 115° to 117°C/1 mm) in 125 ml of dry ether. The mixture was allowed slowly to come to room temperature, refluxed for one hour, and then poured into ice containing 80 ml of concentrated hydrochloric acid. Ammonium chloride (100 g) and 200 ml of concentrated ammonium hydroxide were added and the organic layer was separated. After drying and removing the solvent, the residue was distilled under reduced pressure. The base distilled at 158° to 170°C (1 mm) and solidified. Upon recrystallization from methanol it melted at 112° to 113°C.

brand name

Pagitane (Lilly).

Therapeutic Function

Muscle relaxant, Antiparkinsonian

Pharmacokinetics

Cycrimine is a central anticholenergic used in the treatment of the symptoms of Parkinson's disease. It is a drug used to reduce levels of acetylcholine. Acetylcholine is usually in balance with dopamine neurotransmitters, however lower levels of dopamine are present in the brain of patients suffering from Parkinson's disease. By lowering levels of acetylcholine, it is thought that this balance may be restored.
