Biochem/physiol Actions

SA4503 is a high affinity, orally active non-opioid intracellular receptor sigma-1 (σ1R) selective agonist (IC50 = 17.4 nM against 200 nM (+)-pentazocine for binding σ1R), exhibiting ~100-fold less affinity for the sigma 2 receptor subtype (σ2R) and little or no affinity toward 36 other receptors, ion channels and second messenger systems. Oral administration is reported to elicit cerebral acetylcholine (ACh) release in rat frontal cortex and hippocampus (5-20 mg/kg p.o.) and reduce immobility time in a mouse forced swimming test (Immobility time = 214.8 s without vs. 111.6 s with 1.0 mg/kg oral dosage).

We found that 1-(3,4-dimethoxyphenethyl)-4-(3-phenylpropyl) piperazine dihydrochloride (SA4503), a potent and selective sigma 1 receptor agonist, significantly enhanced the cerebral acetylcholine (ACh) release in the rat using in vivo brain microdialysis technique. Interestingly, the significant enhancement of ACh release elicited by

Two series of novel ether analogs of the sigma (σ) receptor ligand 1-[2-(3,4-dimethoxyphenyl)ethyl]-4-(3-phenylpropyl)piperazine (SA4503) have been prepared. In one series, the alkyl portion of the 4-methoxy group was replaced with allyl, propyl, bromoethyl, benzyl, phenethyl, and phenylpropyl moieties. In the

Haloperidol is an antipsychotic drug that inhibits the dopamine D2 receptor among others. Haloperidol also binds the sigma-1 receptor (σ1R) and inhibits it irreversibly. A serious outcome of haloperidol treatment of schizophrenia patients is death due to sudden cardiac failure.

Cardiovascular diseases are risk factors for depression in humans. We recently proposed that σ1 receptor (σ1R) stimulation rescued cardiac hypertrophy and heart failure induced by transverse aortic constriction (TAC) in mice. Importantly, σ1R stimulation reportedly ameliorates depression-like behaviors in rodents.

This study examined the effect of the N-phenylpropyl-N'-substituted piperazine ligands SA4503 (3.4-dimethoxyphenethyl), YZ-067 (4-methoxyphenethyl), YZ-185 (3-methoxyphenethyl) and Nahas-3h (4-methoxybenzyl) on methamphetamine-induced hyperactivity in mice. In a previous study in rats, SA4503 increased methamphetamine-induced hyperactivity at a lower ligand dose and
