PHA-543613 was discovered by Pfizer and has been under development primarily as a potential treatment of schizophrenia. PHA-543613 acts as an agonist to the Neuronal acetylcholine receptor protein alpha-7 subunit. A single human trial was conducted in healthy human volunteers, but the compound has been studied extensively in rat models for schizophrenia as well as Parkinson's disease and Alzheimer's disease.

Propylnorapomorphine is a potent and selective D2 receptor agonist. Propylnorapomorphine is used as a tool compound to label dopamine receptors in rodent brain, and elicits dopaminergic behavioural effects. It stimulates motor activity, induces stereotypic behaviour and sexual stimulation. Propylnorapomorphine was investigated in clinical trial against Parkinson's disease and schizophrenia

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.

Carfenazine (brand name Proketazine) is an antipsychotic and tranquilizer of the phenothiazine group. It is used in the treatment of acute or chronic schizophrenic reactions in hospitalized patients. Proketazine blocks postsynaptic mesolimbic dopaminergic D1 and D2 receptors in the brain; depresses the release of hypothalamic and hypophyseal hormones and is believed to depress the reticular activating system thus affecting basal metabolism, body temperature, wakefulness, vasomotor tone, and emesis. The following is a list of possible side effects that may occur from all constituting ingredients of Proketazine: akathisia, tardive dyskinesia, extrapyramidal symptoms, allergic purpura.

LEVAMFETAMINE the levorotatory form of amphetamine. L-amphetamine, is a central nervous system (CNS) stimulant known to increase wakefulness and concentration in association with decreased appetite and fatigue. Pharmaceuticals that contain levoamphetamine are currently indicated and prescribed for the treatment of attention deficit hyperactivity disorder (ADHD), obesity, and narcolepsy in some countries. L-Amphetamine succinate was sold in Hungary between 1952 and 1955 under the brand name Cydril.

Pregnenolone is an endogenous steroid and precursor the biosynthesis of most of the steroid hormones, including the progestogens, androgens, estrogens, glucocorticoids, and mineralocorticoids. In addition, pregnenolone is a precursor of neurosteroid pregnenolone sulfate, which is positive modulator of NMDA receptors and negative modulator of GABAA. Pregnenolone itself is a negative allosteric modulator of cannabinoid receptors. Pregnenolone is available as a dietary supplement, and is being investigated in clinical trials agains schizophrenia, bipolar disorder, major depressive disorder, marijuana dependency and other conditions.

Butyric acid (butanoic acid) belongs to a group of short-chain fatty acids and is thought to play several beneficial roles in the gastrointestinal tract. The butyric anion is easily absorbed by enteric cells and used as a main source of energy. Moreover, butyric acid is an important regulator of colonocyte proliferation and apoptosis, gastrointestinal tract motility and bacterial microflora composition in addition to its involvement in many other processes including immunoregulation and anti-inflammatory activity. Butyric acid shows a protective effect in inflammatory response secondary to inflammatory bowel diseases. A beneficial effect of butyric acid as one constituent of a multifaceted mechanism modulating gastrointestinal function has also been stressed in patients with the stoma and coexisting constipation. Butyric acid supplementation combined with the use of probiotics should be adopted as one of the basic therapeutic strategies in this patient group, preceding treatment with laxatives. Sodium butyrate in the form of enemas (combined in a mixture with A-300 silicon dioxide) may be a successful method of therapeutic management in patients with radiation proctitis. Sodium butyrate may also prevent diarrhea through an increased passive absorption of water in the colon and its effects on the gut microflora.
