Inhibition of Respiration in a Flagellate Protozoon by Hypocholesterolemic Drugs

Abstract

SEVERAL hypocholesterolemic drugs uncouple oxidative phosphorylation in rat liver mitochondria1. Also some of these drugs, for example, benzmalecene and triparanol (‘MER-29’), inhibit multiplication of Ochromonas danica, a phytoflagellate; oleic acid annuls this inhibition, but sterols or sterol precursors do not2. Do these drugs inhibit synthesis of ATP in O. danica ? It remains to be seen if there is an especially close relation between ATP synthesis and lipid synthesis.
