2-chloro-phenothiazine is an important intermediate in the synthesis of anti-psychotic, anesthetic, anticonvulsant and other pharmaceutical drugs. 2-chlorophenothiazine exerts no effect on cellular bioenergetics and do not inhibit glioblastoma cell proliferation. In the photo-micronucleus test using V79 cells, 2-chlorophenothiazine was identified as photogenotoxin.

Mesoridazine (brand name Serentil) is a phenothiazine antipsychotic. It was marketed in the U.S. for the treatment of schizophrenia, behavioral problems in mental deficiency and chronic brain syndrome, alcoholism and psychoneurotic symptoms, such as anxiety and tension. Due to the risk of serious cardiac events the indicated use of Serentil was limited to severely ill schizophrenic patients who fail other therapies. Based upon animal studies, mesoridazine acts indirectly on reticular formation, whereby neuronal activity into reticular formation is reduced without affecting its intrinsic ability to activate the cerebral cortex. Mesoridazine shows a moderate adrenergic blocking activity in vitro and in vivo and antagonizes 5-hydroxytryptamine in vivo.
Promazine (Sparine) is a phenothiazine neuroleptic used for short-term management of moderate to severe psychomotor agitation and treatment of agitation and restlessness in the elderly. Promazine is an antagonist at types 1, 2, and 4 dopamine receptors, 5-HT receptor types 2A and 2C, muscarinic receptors 1 through 5, alpha(1)-receptors, and histamine H1-receptors. Promazine's antipsychotic effect is due to antagonism at dopamine and serotonin type 2 receptors, with greater activity at serotonin 5-HT2 receptors than at dopamine type-2 receptors. This may explain the lack of extrapyramidal effects. Promazine does not appear to block dopamine within the tuberoinfundibular tract, explaining the lower incidence of hyperprolactinemia than with typical antipsychotic agents or risperidone. Antagonism at muscarinic receptors, H1-receptors, and alpha(1)-receptors also occurs with promazine. Promazine is not approved for human use in the United States. It is available in the US for veterinary use under the names Promazine and Tranquazine.
Chlorpromazine pamoate (also known as chlorpromazine embonate) is a salt of pamoic acid and a chlorpromazine. Pamoate salts are used in pharmaceutical formulations because they show slow dissolution and are useful in formulations where extended duration of action is required. Chlorpromazine is a phenothiazine antipsychotic. It also exerts sedative and antiemetic activity. The precise mechanism whereby the therapeutic effects of chlorpromazine are produced is not known. It has a wide range of activity arising from its depressant actions on the CNS and its alpha-adrenergic blocking and antimuscarinic activities. Chlorpromazine is a dopamine inhibitor; the turnover of dopamine in the brain is also increased. There is some evidence that the antagonism of central dopaminergic function, especially at the D2-dopaminergic receptor, is related to therapeutic effect in psychotic conditions.
