Antilipidemic drugs. Part 2: Experimental study of a new potent hypolipidemic drug, isopropyl-[4'-(p-chlorobenzoyl)-2-phenoxy-2-methyl]-propionate (LF178).

Pharmacological investigations have been carried out on a new p-chlorobenzoyl substituted phenoxy-isobutyric acid derivate with potent antilipidemic activity, isopropyl-[4'-(p-chlorobenzoyl)-2-phenoxy-2-methyl]propionate (LF 178; procetofene; Lipanthyl¿). The compound depressed total lipids and total cholesterol significantly in the normal rat from 15-20 mg/kg upwards. At 100 mg/kg, the drug-induced depression of total lipids was twice the effect observed with 300 mg/kg of clofibrate.

A systematic antilipidemic structure-activity relationship study was carried out on a series of alcoyl- and benzoyl-phenoxy-carboxylic acids.

A systematic antilipidemic structure-activity relationship study was carried out on a series of alcoyl- and benzoyl-phenoxy-carboxylic acids. The introduction of a p-chlorobenzoyl moiety into the original phenoxy-isobutyric acid enhanced antilipidemic activity significantly. Chlorine meta substitution or chlorine disubstitution abolished activity.

Atilipidemic drugs. Part 5: Evaluation of the hypolipidemic effect of LF 178 in 191 patients affected by the atherogenic form of endogenous hyperlipoproteinemia (types IIa, IIb and IV).

The effect of isopropyl-[4'-(p-chlorobenzoyl)-2-phenoxy-2-methyl]-propionate (LF 178; procetofene; Lipanthyl), a new hypolipidemic agent, has been evaluated in 191 patients affected by endogenous hyperlipoproteinemia (IIa, IIb and IV). Data were collected from patients on active drug trial from 1 to 18 months. The daily administered dose varied from 200 to 400 mg according to pretreatment dietary stabilized lipid values.
