Background

Ki: 2.2 and 13091 nM for σ1 and σ2 receptors respectively.

PRE-084 hydrochloride is a selective σ1 agonist with high affinity, rather than over PCP receptors (IC50 > 100000 nM) and several other receptor systems. It was reported that sigma (s) receptor ligands to alleviate learning and memory impairments on several pharmacological and pathological rodent models of amnesia, involving the s1 subtype of s receptor.

In vitro: PRE-084 had an IC50 of 44 nM in the receptor assay and an IC50 of more than 100,000 nM for PCP receptors and an IC50 higher than 1 0,000 nM in many other receptor systems. In general, hydroxy-substituted phenyl groups in these compounds like PRE-084 tended to have attenuated potency at a receptors, whereas methylphenyl and chlorophenyl substitutions enhanced potencies. Reduction of cycloalkyl ring size lowered potencies for a receptors and quatemized amine groups invariably decreased the compound’s potencies. [1]. The Sig-1R agonist PRE084 not only increases cell survival, but also counteracts the deleterious effects caused by NMHP in neuronal PC6.3 cells. Particularly, PRE084 stimulates the NF-kB pathway that is compromised by the expression of mutant huntingtin proteins, increasing the levels of cellular antioxidants. These data show that the Sig-1R agonist beneficially effects on models of HD and that compounds binding the Sig-1R may be potent targets for future drug development in HD [2].

In vivo: After exposure to CO or 14 days after intoxication with trimethyltin, the spontaneous alternation deficits was reversed significantly by the selective sigma1 ligand PRE-084 (1 mg kg-1) [3]. Administration of Pre-084 (5 mg/kg, i.p.) inhibited citric-acid-induced cough in guinea-pigs. In addition, when administered by aerosol, sigma agonist Pre-084 (1 mg/ml) inhibited cough [4].

Clinical trial: So far, no clinical study has been conducted.
