Paraoxon is an odorless, reddish-yellow oil. Paraoxon is an aryl dialkyl phosphate where both the alkyl groups are ethyl and the aryl group is 4-nitrophenyl. It is a cholinesterase or acetylcholinesterase (AChE) inhibitor. It is an organophosphate oxon, and the active metabolite of the insecticide parathion. Paraoxon is one of the most potent acetylcholinesterase-inhibiting insecticides available, around 70% as potent as the nerve agent sarin, and so is now rarely used as an insecticide due to the risk of poisoning to humans and other animals. Exposure to Paraoxon can cause rapid, severe organophosphate poisoning with headache, sweating, nausea and vomiting, diarrhea, loss of coordination, and death. Paraoxon is on the Hazardous Substance List because it is cited by DOT and EPA. Parathion is converted in the body in part to paraoxon, a strong inhibitor of the enzyme acetyl cholinesterase. Upon inhibition of this enzyme in the tissues, acetylcholine, the substance responsible for transmission of nerve impulses in much of the nervous system, accumulates, producing an initial overstimulation and subsequent blockage of nerve stimuli. Paraoxon was once used as an opthamological drug against glaucoma.

Thiocolchicoside is a muscle relaxant that has been authorised by national procedures in several EU Member States for use by mouth or injection into the muscles in the treatment of painful muscular disorders. Thiocolchicoside is marketed under the brand name Muscoril among others. Thiocolchicoside (TCC) is used clinically for its muscle relaxant, anti-inflammatory, and analgesic properties, and it has been shown to interact with gamma-aminobutyric acid (GABA) type A receptors (GABAARs) and strychnine-sensitive glycine receptors in the rat central nervous system.

Phosphocreatine (creatine phosphate, PCr, PC) is the phosphorylated form of endogenous creatine that serves as a rapidly mobilizable reserve of high-energy phosphates in skeletal muscle and the brain of vertebrates. Phosphocreatine is a key component in the intracellular system of energy buffering and transports from the site of energy production to the site of energy utilization to ensure that supply meets the high and dynamic demands of the heart. Phosphocreatine can anaerobically donate a phosphate group to ADP to form ATP during the first two to seven seconds following an intense muscular or neuronal effort. Conversely, excess ATP can be used during a period of low effort to convert creatine to phosphocreatine. The reversible phosphorylation of creatine is catalyzed by several creatine kinases. Particularly, PCr makes the energy of phosphoryl bonds of adenosine triphosphate (ATP) available at the myofibrillar creatine kinase that allows myocardium contraction. Supplementation with PCr was, therefore, suggested as potentially beneficial in patients with acute and chronic myocardial ischaemic injury. Phosphocreatine has been tried in the treatment of cardiac disorders and has been added to cardioplegic solutions. Phosphocreatine is used intravenously in hospitals in some parts of the world for cardiovascular problems under the name Neoton and also used by some professional athletes, as it is not a controlled substance.

Valnoctamide is a valproic acid derivative associated with a decreased risk for congenital abnormalities and developed by Beersheva Mental Health Center for treatment mania. Valnoctamide has been marketed as an anxiolytic and sedative in several European countries (as Nirvanil), including Italy, Holland, and Switzerland, until the year 2000 but was not actively promoted as an anticonvulsant. It was marketed in the U.S. as Axiquel by McNeil Laboratories in the 1970s. In mice, valnoctamide has been shown to be distinctly less teratogenic than valproic acid. Injection of 3 mkmol ⁄ kg at day 8 of gestation produced only 1% exencephaly (as compared to 0–1% in control mice and 53% in valproate-treated mice). Embryolethality rates showed similar results: 52% with valproate versus 5% in the controls and 2% with valnoctamide. Valnoctamide's patent is expired, and it is not the property of any major pharmaceutical company. Valnoctamide has potential as a therapy in epilepsy including status epilepticus (SE) and neuropathic pain and is currently being developed for the treatment of mania and Schizoaffective Disorder. In clinical trials, Valnoctamide was well tolerated but lacked efficacy in the treatment of symptoms in patients with acute mania.

Creatinolfosfate (or creatinol-O-phosphate, or COP) possesses anti-ischemic and anti-arrhythmic activities associated with improved ionic balance and heart performance. This compound exerts its cardioprotective effect by action on anaerobic glycolysis. The results of the toxicological studies showed that creatinolfosfate didn’t have side effects.

Choline alfoscerate (alpha-Glycerylphosphorylcholine or Alpha-GPC) is a nootropic choline-containing phospholipid. Choline alphoscerate increases the release of acetylcholine in rat hippocampus, facilitates learning and memory in experimental animals, improves brain transduction mechanisms and decreases age-dependent structural changes occurring in rat brain areas involved in learning and memory. The compound exerts neuroprotective effects in models of altered cholinergic neurotransmission and of brain vascular injury. In clinical studies choline alphoscerate improved memory and attention impairment, as well as affective and somatic symptoms in dementia disorders. In Europe alpha-GPC is a prescription medication for the treatment of Alzheimer's disease. It is available in two forms; one is taken by mouth, and the other is given as a shot. In the United States alpha-GPC is only available as a dietary supplement, mostly in products promoted to improve memory. Other uses for alpha-GPC include treatment of various kinds of dementia, stroke, and "mini-stroke" (transient ischemic attack, TIA). Alpha-GPC is also used for improving memory, thinking skills, and learning.

Meldonium (3-(2,2,2-trimethylhydrazinium)propionate; MET-88; quaterine, trade-named as Mildronate) is an antiischemic drug developed at the Latvian Institute of Organic Synthesis. It is a clinically used in the treatment of heart failure, myocardial infarction, arrhythmia, atherosclerosis, and diabetes. Mechanism of action is based on the regulation of energy metabolism pathways through l-carnitine lowering effect. L-Carnitine biosynthesis enzyme γ-butyrobetaine hydroxylase and carnitine/organic cation transporter type 2 (OCTN2) are the main known drug targets of meldonium, and through inhibition of these activities, meldonium induces adaptive changes in the cellular energy homeostasis. Since L-carnitine is involved in the metabolism of fatty acids, the decline in its levels stimulates glucose metabolism and decreases concentrations of l-carnitine related metabolites, such as long-chain acylcarnitines and trimethylamine-N-oxide. Meldonium is used in neurological clinics for the treatment of brain circulation disorders. It appears to improve patients' mood; they become more active, their motor dysfunction decreases, and asthenia, dizziness, and nausea become less pronounced. CNS effects of Meldonium could be mediated by stimulation of the nitric oxide production in the vascular endothelium by modification of the gamma-butyrobetaine and its esters pools. It is hypothesized that mildronate may increase the formation of the gamma-butyrobetaine esters. Meldonium was on the World Anti-Doping Agency’s (WADA) list of drugs being monitored until September 2015, when it was added to the list of banned substances, effective January 1, 2016.
