1-[1-(4-Chlorophenyl)cyclobutyl]-3-methylbutylamine hydrochloride

The Uses of 1-[1-(4-Chlorophenyl)cyclobutyl]-3-methylbutylamine hydrochloride

A metabolite of Sibutramine, a serotonin and noradrenaline reuptake inhibitor (SNR). Decreases calorie intake and increases energy expenditure.

Biological Activity

Potently active primary amine metabolite of sibutramine (1-(4-Chlorophenyl)-N,N-dimethyl-a-(2-methylpropyl)cyclobutanemethanamine hydrochloride ) that exhibits a similar pharmacological profile to the parent compound. Inhibits serotonin and noradrenalin reuptake more potently than sibutramine in vitro . In vivo, reduces food intake in rodents following i.c.v. administration and increases energy expenditure via thermogenesis.

in vitro

simultaneous application of bts 54-505 with 5-ht resulted in a prolongation of the recovery time from the 5-ht-mediated suppression of discharge activity. bts 54-505 also prolonged the recovery time from a na-mediated potentiation of firing. these effects on recovery time are attributed to the inhibition of uptake of both 5-ht and na by bts 54-505. the amplitude of the response to 5-ht or na was unaffected by co-ejection of bts 54-505 [1].

in vivo

the secondary (bts 54-354) and primary (bts 54-505) amine metabolites of sibutramine hcl exhibit similar in vivo pharmacological activity to the parent compound. thus, each compound displays potent activity in acute behavioural models predictive of antidepressant effects and a comparable ability to inhibit the uptake of monoamines [2].
