Behavioral effects of 2,5-dimethoxy-4-methylamphetamine ( DOM) in rats and mice.
The characteristics of the behavioral effects of 2,5-dimethoxy-4-methylamphetamine ( DOM or STP) were compared with those of mescaline and methamphetamine in rats and mice. DOM significantly increased locomotor activity in an open-field situation at 0.5-1.0 mg/kg i.p., but at doses above 5 mg/kg i.p. caused biphasic changes, i.e. an initial decrease followed by an increase in motility and exploratory behavior. This hyperactivity was not accompanied by simultaneous increase in rearing. Besides, DOM induced head twitches in rats as well as in mice at doses above 0.1 mg/kg i.p., and marked backward locomotion only in rats at doses larger than 5 mg/kg i.p. The occurrence of backward locomotion might be attributable to the initial decrease in general activity. Behavioral effects of DOM were different from those of either mescaline or methamphetamine although they resembled those of mescaline in some respects.[1]References
