N-Phenethylaminopropiophenones as lipogenesis inhibitors

A method of inhibiting lipogenesis in a mammal, which comprises administering, to a mammal in need of such treatment, orally or parenterally a lipogenesis inhibiting amount of a compound of the formula:

• ##STR2## wherein R is hydrogen or hydroxyl;
• R.sup.1 is hydrogen or methyl;
• R.sup.2 is hydrogen or methyl;
• n is zero, one or two;
• X is hydroxyl, with the proviso that when n is one, the hydroxyl moiety is bonded to the carbon atom at the 4-position in the phenyl ring, and when n is two, the hydroxyl moieties are bonded to the carbon atoms in the 3- and 4-positions of the phenyl ring;
• m is one;
• Y is one of
• nitro;
• hydroxyl;
• alkyl;
• alkoxy;
• alkylthio;
• alkanoylamino;
• alkenoylamino;
• 3-(dialkylamino)alkyleneoxy;
• 2-(dialkenylamino)alkyleneoxy, and their pharmacologically acceptable acid addition salts.
