Research for Depression
Tetracyclic Antidepressants

Noradrenaline is a neurotransmitter transmitting excitement and it is distributed in sympathetic nerve terminals and central nervous system. It is secreted in the brain due to stress such as pain and fear and is said to induce the fight or flight response. Insufficiency of noradrenaline in the brain is considered as one of the causes for depression.
Tetracyclic antidepressants increase the concentration of noradrenaline in synaptic gaps exhibiting antidepressant activity.

1. Maprotiline hydrochloride
Maprotiline hydrochloride binds to noradrenaline transporters, thereby inhibits noradrenaline reuptake in the brain resulting in an increase in the noradrenaline concentration in the synaptic gaps.

- Assay (HPLC): 98.0+ %
- Solubility: Soluble in methanol and chloroform
- CAS No.: 10347-81-6
- C20H23N·HCl = 313.86
2. Mianserin hydrochloride
Mianserin hydrochloride blocks presynaptic α2 adrenaline autoreceptor, thereby accelerates noradrenaline release into synaptic gaps. Acceleration of metabolic turnover of noradrenaline in the brain has also been reported. It exhibits 5-HT receptor blocking activity.

- Assay (HPLC): 99.2% (measured value in the initial production lot)
- Solubility: Soluble in methanol
- CAS No.: 21535-47-7
- C18H20N2·HCl = 300.83
