General description

Spiperone is a butyrophenone antipsychotic agent. It induces calcium-dependent chloride secretion in the airway and functions as a potential therapeutic target for cystic fibrosis.


Spiperone was used to study the role of dopamine receptors in facilitating the male sexual behavior in quails.6
Spiperone has been used to block the actions of 5-hydroxytryptamine (5-HT) receptor. It also has been used to study its anti tumor effects in glioblastoma (GBM) cell lines.

MS Binding Assays are a label-free alternative to radioligand binding assays. They provide basically the same capabilities as the latter, but use a non-labeled reporter ligand instead of a radioligand. In contrast to radioligand binding assays, MS Binding Assays offer-owing...

Biased agonism describes the ability of ligands to stabilize different conformations of a GPCR linked to distinct functional outcomes and offers the prospect of designing pathway-specific drugs that avoid on-target side effects. This mechanism is usually inferred from pharmacological data...

In humans intimal thickening is aprerequisite of atherosclerosis. Application of a silicone collar around the rabbit carotid artery induces an intimal thickening but in addition it increases the sensitivity to the vasoconstrictor action of serotonin (5-hydroxytryptamine, 5-HT). The 5-HT receptors...

Interneurons from the CA1 lacunosum-moleculare (L-M) region were isolated by trypsin-hyaluronidase treatment and mechanical trituration of the L-M. Interneurons isolated in this manner were multipolar with several dendritic processes and could be distinguished from CA1 pyramidal neurons. The properties of...
