5.4 Mechanism of Action

Lonidamine is an orally administered small molecule that inhibits glycolysis by the inactivation of hexokinase. Hexokinase is an enzyme that catalyzes glucose, the first step in glycolysis. The inhibition of hexokinase by lonidamine is well established. In addition, there is evidence that lonidamine may increase programmed cell death. This stems from the observation that mitochondria and mitochondria-bound hexokinase are crucial for induction of apoptosis; agents that directly effect mitochondria may, therefore, trigger apoptosis. Indeed, in vitro models with lonidamine exhibit the hallmarks of apoptosis, including mitochondrial membrane depolarization, release of cytochrome C, phosphatidylserine externalization, and DNA fragmentation.
