Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/23735322 | https://www.ncbi.nlm.nih.gov/pubmed/24517902 | https://www.ncbi.nlm.nih.gov/pubmed/22785385 | https://www.ncbi.nlm.nih.gov/pubmed/26826431

SB-699551 is the first selective serotonin 5A receptor antagonist. SB-699551 showed an anxiolytic-like property in animal model. It demostrated efficacy against schizophrenia-like cognitive deficits and negative symptoms in rats. Blockade of 5-HT5A receptor with SB-699551 appear to be able to impair the consolidation of memory in rodents. In addition, 5-HT-induced spinal antinociception in the capsaicin and acetic acid tests was blocked by SB-699551.

In Vitro Use Guide
In guinea pig dorsal raphe slices, SB-699551-A (1 uM) did not alter neuronal firing per se but attenuated the 5-carboxamidotryptamine-induced depression in serotonergic neuronal firing in a subpopulation of cells insensitive to the 5-HT1A receptor-selective antagonist WAY-100635 (100 nM).
