Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/16915381 | https://www.ncbi.nlm.nih.gov/pubmed/8566121 | https://www.ncbi.nlm.nih.gov/pubmed/8768719 | http://link.springer.com/chapter/10.1007%2F978-94-011-0429-6_9

WAY-100635 is an achiral phenylpiperazine derivative that originally discovered as an antagotist of 5-HT1A receptor. Later WAY-100635 was described as a potent dopamine D4 receptor agonist. WAY-100635 was in preclinical studies for the treatment of Diabetes mellitus, Anxiety and Cognition disorders, howevere the development was discontinued. Isotope labeled WAY-100635 could be used for the study of central 5-HT 1A receptors with potential for application to the study of neuropsychiatric disorders and to the human pharmacology of psychoactive drugs.

CNS Activity

Curator's Comment: WAY-100635 is CNS active in animals. Isotope labeled WAY-100635 could be used for the qualitative and quantitative study of 5-HT1A receptors in the human brain.

Sample Use Guides

mice: 3.0 mg/kg, i.p. rats: 200 ng, injected in the median raphé nucleus cats: 0.025-0.5 mg/kg i.v.
Route of Administration: Other
Exposure of h5-HT(1A) CHO cells to WAY-100635 decreased the cell-surface h5-HT(1A) receptor density in a way that was both time (24-72 h) and concentration (1-100 nM) dependent. In dorsal raphe nucleus slices superfused with WAY 100635 (10 nM), the majority of putative 5-HT neurons increased their firing rate. In addition, WAY 100635 completely prevented the decrease in firing rate produced by 5-HT (3-15 microM), 8-OH-DPAT (10 nM), 5-carboxamidotryptamine (20 nM) and lesopitron (100 nM).
