Abstract The sigma (σ) receptor and its agonists have been implicated in a myriad of cellular functions, biological processes and diseases. Whereas the precise molecular mechanism(s) of σ receptors and their involvement in cancer cell biology have not been elucidated, recent work has started to shed some light on these issues.

There is a critical need for new analgesics acting through new mechanisms of action, which could increase the efficacy respect to existing therapies and/or reduce their unwanted effects. Current preclinical evidence supports the modulatory role of the sigma-1 receptor (σ1R) in nociception, mainly based on the pain-attenuated phenotype of σ1R knockout ...

Sigma-2 Receptor Ligands: Neurobiological Effects
Current Medicinal Chemistry, 2015Sigma-2 receptor is a widely distributed protein, which can modulate cell proliferation and involved in the pathogenesis of tumor. Photoaffinity labelling techniques testified that its molecular size is about 18 kDa. Recent studies indicated that sigma-2 receptor modulates the cytosolic Ca2+ concentration, dopaminergic transmission, and cocaine-induced

(Aminoalkoxy)chromones. Selective .sigma. receptor ligands
Journal of Medicinal Chemistry, 1992A series of (aminoalkoxy)chromones has been prepared, members of which bind potently (16-100 nM) at the sigma binding site and bind weakly (greater than 1000 nM) at the dopamine D2 receptor and 33 other receptors, second messenger systems, and ion channels.

Sigma receptors in schizophrenic cerebral cortices
Neurochemical Research, 1992Antipsychotics represent high affinity for sigma receptors and sigma-like drugs often have the psychotomimetic properties. Besides, the receptors are unevenly distributed in human brain. These findings suggest that sigma receptors might be involved in the pathophysiology of schizophrenia. Sigma receptors in rat and human brain were measured with [3H]-1,

[Sigma (sigma) receptor and neurosteroids].
Nihon yakurigaku zasshi. Folia pharmacologica Japonica, 2000Studies on the sigma receptor and related compounds are becoming more attractive since they were found to be closely related to higher brain functions such as memory, learning, depression, anxiety, schizophrenia and neuroprotection. Along with these pharmacological findings, the single transmembrane-type, non-metabotropic sigma binding protein has been

Sigma opioid receptor; SKF-10,047 update
Neuropeptides, 1985We found that (-)-SKF-10,047 blocks EEG and behavioral effects of morphine in the naive rat, precipitates withdrawal in morphine-dependent rats, produces physical dependence as evidenced by naloxone-induced withdrawal, and displaces [3H] dihydromorphine from brain homogenates. (+)-SKF-10,047 did not produce dependence upon chronic treatment, and it did

Sigma-1 receptor and inflammatory pain
Inflammation Research, 2015The sigma-1 receptor (Sig-1R) is a unique ligand-regulated molecular chaperone that interacts with several protein targets such as G protein-coupled receptors and ion channels to modulate their activity. Sig-1R is located in areas of the central and peripheral nervous system that are key to pain control.

Sigma receptor modulators: a patent review
Expert Opinion on Therapeutic Patents, 2013Sigma receptors are involved in several central nervous system (CNS) disorders, including mood disorders (depression and anxiety), psychosis, schizophrenia, movement disorders (i.e., Parkinson's disease) and memory deficits (i.e., Alzheimer's disease).

Analogues of the decahydrobenzoquinolin-5-one class of sigma (σ) receptor ligands were used to probe the structure-activity relationship trends for this recently discovered series of σ ligands. In all, 29 representatives were tested for σ and opioid receptor affinity, leading to the identification of compounds possessing improved σ1 selectivity and ...
