Ritanserin (INN, USAN, BAN) is a serotonin receptor antagonist which was never marketed for clinical use but has been used in scientific research. In humans, ritanserin increases deep slow-wave sleep, improved liveliness in a variety of psychiatric disorders and facilitated participation in behaviour therapy. During clinical trials, unexpected observations indicated that ritanserin may be of value in treating obsessive-compulsive disorder, acute mania, negative symptoms of schizophrenia, drug addicts, etc. Clinical observations confirmed the efficacy of ritanserin in the chronic withdrawal phase after detoxification from ethanol. Ritanserin had been in phase III clinical trials by Janssen L.P. for the treatment of anxiety disorder and major depressive disorder. However, the clinical development of ritanserin was discontinued.

HeLa and human glioblastoma cells, U87 and U251, were treated as follows: 4 and 40 mkM of R59022 and ritanserin, 40 mkM ketanserin, and 100 nM PMA for 30 min with and without pretreatment with 500 nM bisindolylmaleimide II for 1 h. For additional PKC activation experiments, HeLa cells were treated with 10 mkM TCB-2 for 6 h with and without co-treatment with 40 mkM ketanserin, 40 mkM ketanserin alone, and 500 nM bisindolylmaleimide II for 1 h. The cells were lysed in IPBB, 20 mM Tris-HCl pH 7.5, 150 mM NaCl, 1% Triton X-100 and protease inhibitors and the cell lysate was cleared by centrifugation at 16,000g for 10 min.
