Abstract

LY134046, a potent, selective inhibitor of rat brain phenylethanolamine N-methyltransferase, was shown to increase activity in 18- and 19-day-old rats. The effects on day 25 were different, with LY134046 causing a decrease in activity. The effects of yohimbine, a selective antagonist of the alpha-2 adrenergic receptor, were markedly different from LY134046, causing a decrease in activity on day 19. These data suggest that epinephrine synthesis may play an inhibitory role in the regulation of activity in young rats.
