An open problem of the lipid lowering agent ciprofibrate (rac-2-[4-(2,2-dichlorocyclopropyl)-phenoxy]-2-methylpropanoic acid, CAS 52214-84-3) is its metabolism concerning the conjugation with amino acids and glucuronic acid. It could be solved by syntheses of the needed reference compounds--unknown up to now--and administration of ciprofibrate to volunteers and rats. Unexpectedly the conjugation compounds with amino acids are stable in vitro and in metabolism.
