Biochem/physiol Actions

NB-598 is a potent and specific inhibitor of mammalian squalene epoxidase (SQLE) that suppresses triglyceride biosynthesis through the farnesol pathway. It decreases cholesterol levels in cells. NB-598 exhibit potent cytotoxic effects in subset of f neuroendocrine tumors, such as small cell lung cancers through accumulation of toxic squalene with in sensitive cancer cells.

We recently demonstrated that squalene synthase (SQS) inhibitors reduce plasma triglyceride through an LDL receptor-independent mechanism in Watanabe heritable hyperlipidemic rabbits (Hiyoshi et al. 2001. Eur. J. Pharmacol. 431: 345-352). The present study deals with the mechanism of the inhibition
