Zimelidine Dihydrochloride, is a selective 5-HT uptake inhibitor. It modulates nociception and induces hyperglycemia in vivo, and is an orally active antidepressant.
Zimeldine is a serotonin uptake inhibitor. Antidepressant.
ChEBI: Zimeldine is a member of styrenes.
To 9 g of n-butyl lithium in 200 ml of dry ether 20 g of 3-bromopyridine is
added as quickly as possible at -40°C without raising the temperature. When the addition is finished the mixture is stirred for another 30 minutes.
Thereafter 32.5 g of ω-dimethylamino-4'-bromopropiophenone is added in
such a way that the temperature does not exceed -40°C. The cooling is
discontinued and the mixture is stirred during the night whereupon the
reaction mixture is poured onto ice and diluted HCl, which is washed with
ether and is extracted with 20 ml of methylene dichloride. The methylene
dichloride is dried and evaporated. The crystals are dissolved in water, which
then is made alkaline with a solution of Na 2 CO 3 , is extracted with ether, dried,
and evaporated and recrystallized from isopropyl ether, petroleum ether 1:1.
Yield 4 g of 1-(4'-bromophenyl)-3-(N,N-dimethylamino)-1-(3''-pyridyl)-
propanol. Melting point 67°C.
3.6 g of 1-(4'-bromophenyl)-3-(N,N-dimethylamino)-1-(3''-pyridyl)-propanol
are dissolved in 15 ml of 85% H 2 SO 4 and heated at 170°C for 10 minutes.
The reaction mixture is poured into 60 ml of water, which is then made
alkaline with 10 N NaOH, and is extracted with 2 x 25 ml of ether. The ether
is dried with Na 2 SO 4 , treated with active carbon and evaporated. The residue
is dissolved in 25 ml of acetone and an equivalent amount of oxalic acid
dissolved in 25 ml of acetone is added. The precipitate obtained is filtered off,
is dissolved in 50 ml of water, which is made alkaline with 10 N NaOH and is
extracted with 2 x 25 ml of ether. The ether solution is dried with Na 2 SO 4 and
is filtered, whereupon dry HCl is introduced. The precipitate obtained is
filtered off. Yield 1.2 g of 3-(4'-bromophenyl)-3-(3''-pyridyl)-
dimethylallylamine dihydrochloride (H 102/09). Melting point 193°C.

Zimeldine, an inhibitor of serotonin uptake, was introduced in
1982 for the treatment of depressive illness. By 1983 its use had been associated
with incidences of hypersensitivity of varying severity and serious neurological
side effects including the Guillain-Barr, syndrome. Following discussions with the
National Board of Health and Welfare of Sweden, the major manufacturer decided
to withdraw the drug on a worldwide basis.
5-HT re-uptake inhibitor; selective over noradrenalin and dopamine uptake (IC 50 values are 0.33, 8.2 and 12 μ M respectively). Modulates nociception and induces hyperglycemia in vivo , and is an orally active antidepressant.
