Alizapride (Litican, Plitican, Superan, Vergentan) is a dopamine antagonist with prokinetic and antiemetic effects used in the treatment of nausea and vomiting, including postoperative nausea and vomiting. It is structurally related to metoclopramide and other benzamides.[1]

Mechanism

Alizapride blocks D2 dopamine receptors in the vomiting center.[2]

Since alizapride is able to cross the blood-brain barrier, adverse effects may include temporary extrapyramidal motor disorders such as acute dystonia and dyskinesia.[3]

It has a plasma half-life of 3 hours.[3]

Synthesis

The synthesis of Alizapride happens in multiple steps:[4]

Synthesis of Alacepril
Synthesis of Alacepril

4-Aminosalicylic acid is first methylated using dimethyl sulfate. A nitro group is then introduced that is reduced using Raney nickel to afford an amino group. The two amino groups are then closed to a triazole ring using sodium nitrite and hydrochloric acid. This is then condensed with 1-allyl-2-aminomethylpyrrolidine to afford Alizapride.
