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.

Dynamic (solvent generated) cation-exchange systems for the separation of drugs and main metabolites derived from butyrophenone and diphenylpiperidine (haloperidol, pimozide, halopemide) were investigated. The effect of organic modifier, detergent, counter-ion concentration and of the pH on the retention has been

Halopemide inhibits 3H-BZ binding to crude and washed rat forebrain membranes with IC50 values of 16-25 microM. Its putative metabolites are considerably less active. The actions of halopemide are probably not directly related to its ability to interfere with high-affinity

Apomorphine (0.05 mg/kg intravenously) was given to conscious dogs, and gastrin levels were measured in peripheral venous blood with a radioimmunoassay. Apomorphine induced an increase of gastrin levels which peaked at 5 min. The peripheral dopamine D-2/DA2 receptor antagonist domperidone
