  • Patent number: 4261988
    Abstract: Compounds useful in the treatment of cholesterolaemia are of the general formula ##STR1## or salts thereof in which R.sup.1 and R.sup.2 independently denote radicals including hydrogen, alkyl, aryl and heterocyclic radical or together complete a carbocyclic or heterocylic ring, R.sup.3 denotes a radical ##STR2## in which R.sup.9, R.sup.10 and R.sup.11 include hydrogen, cyano, nitro, alkyl and aryl or, in pairs, complete carbocyclic rings, X denotes cyano, nitro or substituted carbonyl, sulphonyl or phosphonyl group, R.sup.4 is hydrogen or a radical defined for R.sup.1 or R.sup.3, and R.sup.5, R.sup.6, R.sup.7 and R.sup.8 include hydrogen, nitro, cyano, carboxyl, alkyl and aryl or, in pairs, complete carbocyclic rings, with the proviso that R.sup.1 and R.sup.9 are not both phenyl if X denotes CO--C.sub.6 H.sub.6. The compounds exhibit considerably higher hypocholesterolaemic activity than the known clofibrate and in addition exhibit a pronounced nutritive effect, e.g., in a medicated fodder or premix.
