Norzotepine
Norzotepine is the major human metabolite of Zotepine (HY-103093) and also a NET inhibitor (human IC50 = 4.2 nM). Norzotepine exerts antipsychotic-like and antidepressant-like effects by inhibiting Norepinephrine (HY-13715) reuptake and blocking dopamine D2 (Dopamine D2), histamine H1 (Histamine H1), and 5-HT2 receptors. Norzotepine can be used for research on schizophrenia.

In Vitro
Norzotepine (norZTP) (30 min) potently inhibits mouse and human NET with IC50 values of 11 nM and 4.2 nM, respectively, while showing weak inhibition of mouse SERT with an IC50 of 6191 nM[2].

Parmacokinetics

|---|---|---|---|
| Mice[2] | 3.2 mg/kg | i.p. | 639 ng/g |
In Vivo
Norzotepine (0.3-10 mg/kg; intraperitoneal injection) significantly inhibited MAP-induced hyperactivity, with an ED50 of 0.33 mg/kg intraperitoneal injection[2].
Norzotepine (1-10 mg/kg; intraperitoneal injection) does not induce catalepsy at doses up to 10 mg/kg, with an ED50 of > 10 mg/kg[2].
Norzotepine (1-10 mg/kg; intraperitoneal injection) inhibited APO-induced climbing with an ED50 of 3.9 mg/kg and significantly induced biting at 3 mg/kg[2].
Norzotepine (0.1-1 mg/kg; intraperitoneal injection) significantly antagonized Reserpine (HY-N0480)-induced hypothermia, with an intraperitoneal ED50 of 0.23 mg/kg[2].
Norzotepine (1-10 mg/kg; intraperitoneal injection) significantly reduced spontaneous locomotor activity at doses of 3 and 10 mg/kg, with an ED50 of 3.1 mg/kg[2].
Norzotepine (13.75 mg/kg; intraperitoneal injection; daily; 28 days) produced region-selective increases in D1, D2, and D4 receptors and 5-HT1A receptors, along with a decrease in 5-HT2A receptors[4].
