Application

Halopemide, a non-specific phospholipase D (PLD) antagonist, may be used with selective PLD antagonists (CAY10593, a PLD1 antagonist; CAY10594 or ML298, selective PLD2 antagonist) to help define the role and physiological effects regulated by phospholipase D enzymes. Halopemide may be used as the basis of the design and development of more selective PLD antagonists.

Biochem/physiol Actions

Halopemide is a dopamine receptor antagonist and a phospholipase D2 inhibitor. Halopemide may be used as a screen to identify inhibitors of human PLD2 using an in vitro biochemical assay. It is also inhibitory at benzodiazepine binding sites.

Halopemide is a new psychotropic agent, a structural analogue of the neuroleptics of the butyrophenone type but with different pharmacological and clinical properties. Preliminary clinical findings indicate that halopemide lacks the ability to induce parkinsonism and may be an effective

The resocializing and activating properties of halopemide were investigated in an open study and a double-blind study in 20 patients who had been hospitalized on account of various psychiatric disorders. The results of the open study showed a significant improvement

In vitro, animal studies and acute short-term clinical studies suggest clozapine releases prolactin but the effect is much smaller than that of typical antipsychotics. Repeated early morning trough measures of plasma clozapine and prolactin levels on each subject were studied

Oxiperomide and tiapride are dopamine receptor antagonists claimed to have "antidyskinetic" properties in animal models and the clinic. Halopemide and mezilamine are other dopamine antagonists predicted to lack extrapyramidal side effects in man on the basis of animal studies. Acute
