Talnetant hydrochloride  (Synonyms: SB 223412 hydrochloride; SB 223412-A)

Cat. No.: HY-14552A
Handling Instructions

Talnetant (SB 223412) hydrochloride is a selective, competitive, brain-permeable NK3 receptor antagonist with a Ki of 1.4 nM in hNK-3-CHO cells. Talnetant hydrochloride is 100-fold more selective for hNK-3 relative to the hNK-2 receptor and has no affinity for hNK-1. Talnetant hydrochloride can be used in schizophrenia-related studies.

Description

Talnetant (SB 223412) hydrochloride is a selective, competitive, brain-permeable NK3 receptor antagonist with a Ki of 1.4 nM in hNK-3-CHO cells. Talnetant hydrochloride is 100-fold more selective for hNK-3 relative to the hNK-2 receptor and has no affinity for hNK-1. Talnetant hydrochloride can be used in schizophrenia-related studies[1][2][3].

In Vitro

Talnetant (SB 223412) (0.1-1 μM) hydrochloride can reduce the accumulation of NKB-induced IP in U-2OS cells expressing the human NK3 receptor[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Talnetant (SB 223412) hydrochloride (0.5-2 mg/kg iv, 2min pretreatment) can inhibit the miosis induced by senktide (25µg, iv) in a dose-dependent manner with an ED50 of 0.44mg/kg in conscious rabbits[1].
Talnetant (SB 223412) hydrochloride (i.p., 1-100 mg/kg, 1 h) can significantly attenuate senktide-induced "wet dog wagging" behavior in a dose-dependent manner, significantly increase extracellular dopamine and norepinephrine in the medial prefrontal cortex and reduce haloperidol-induced increases in dopamine levels in the vomeronasal nucleus of freely moving guinea pigs[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Dunkin-Hartley guinea pig[3]
Dosage: 1, 3, 10, 30 or 100 mg/kg
Administration: Intraperitoneal injection; 1 h
Result: Showed a significant attenuation of wet dog shake (WDS) behavior from 31.1 to 16.7 at 30 mg/kg.
Significantly increased extracellular DA levels to 238% and NE levels to 227.1%, without affecting 5-HT levels.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
