Oxidosqualene cyclase (OSC) is a microsomal enzyme that catalyzes the cyclization of monooxidosqualene to lanosterol in the cholesterol synthetic pathway. Ro 48-8071 is an inhibitor of oxidosqualene cyclase (OSC) that has low-density lipoprotein (LDL) cholesterol lowering activity similar to the 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) inhibitor simvastatin. It inhibits OSC from human liver microsomes and HepG2 cells with IC₅₀ values of approximately 6.5 nM and 1.5 nM, respectively. Ro 48-8071 lowered LDL cholesterol ~40% in hamsters at a dose of 150 μg/kg without affecting high-density lipoprotein levels and with no sign of liver toxicity. Ro 48-8071 increases cytochrome P3A mRNA and protein levels in primary rat and murine hepatocyte cultures with a maximal effect at 30 μM.

Ro 48-8071 is an inhibitor of oxidosqualene cyclase.

ChEBI: An aromatic ketone that is 2-fluoro-4'-bromobenzophenone in which the hydrogen at position 4 (meta to the fluoro group) is replaced by a 6-[methyl(prop-2-en-1-yl)amino]hexyl}oxy group. An inhibitor of lanosterol synthase.
