title: [Antilipolytic activity in vitro of various analogs of nicotinic acid. Structure-activity relationship].
abstract: The antilipolytic activity of a series of N aryl-nicotinamides and of alpha picolinic acid, has been tested in vitro. Lipolysis was stimulated by epinephrine (20 micrograms/ml of incubation medium) using rat's epididymal adipose tissue slices. Only N(2-carboxy methyl phenyl) nicotinamide showed antilipolytic effect comparable to that of nicotinic acid at similar concentrations (2 X 10(-5) M). Picolinic acid (10(-4) M) showed no antilipolytic effect. These results, together with those of the literature, are discussed in regard to the relations between structure and antilipolytic activity.
