Potassium Trihydrogen Dioxalate is a Potassium salt used in photography, marble grinding, and in metal polishing. Potassium Trihydrogen Dioxalate is strongly irritating to eyes, mucous and gastrointestinal tract. Potassium Trihydrogen Dioxalate may cause cardiac failure and death after oral administration

The phthalidyl thiazolidine carboxylic ester of ampicillin, talampicillin (Talpen, Beecham), has been introduced recently to improve absorption and to reduce these side effects. After oral administration talampicillin is rapidly absorbed and hydrolysed by tissue esterases in the intestinal wall to release into the circulation ampicillin and the ester moiety, mainly 2-hydroxymethyl-benzoic acid. No unchanged talampicillin is detectable in the peripheral blood. It is not approved by the FDA for use in the United States

Bietaserpine is a derivative of a Rauwolfia alkaloid reserpine. It was used as an antihypertensive agent and marketed in the 1960s in France and Italy. Bietaserpine is believed to act by inhibiting VMAT receptors.

Glafenine is a non-steroidal anti-inflammatory drug (NSAID). Glafenine was withdrawn due to the risk of anaphylaxis and acute kidney failure.

Oxaflumazine acid disuccinate, a neuroleptic drug, was studied in the treatment of psychotic children in a pedopsychiatric environment.

Fluoroethylcholine ion F-18 is ethylcholine labeled with fluorine F 18, a positron-emitting isotope. Fluorine F18 fluoroethylcholine incorporates into tumor cells through an active, carrier-mediated transport mechanism for choline and then is phosphorylated intracellularly by choline kinase, yielding a phosphoryl derivative, and finally is integrated into cellular phospholipids, probably primarily into a phosphatidyl derivative; concentration of this agent in tumor cells as various fluorine F 18 fluoroethylcholine derivatives enables tumor imaging using positron emission tomography (PET). Choline kinase, the enzyme responsible for the phosphorylation of choline, is frequently up-regulated in human tumor cell lines. F18-fluoroethylcholine is used for imaging of prostate cancer and brain tumors, mainly in Europe and Japan.

Octotiamine is an analogue of vitamin B1. As a component of vitamin complex used for the treatment of vitamin B1 deficiency; vitamin B1 supplement.

Potassium tellurate is used as anhidrotic. It is toxic to most living organisms. Gram-negative bacteria are among the microorganisms most sensitive to this oxyanion.

Butedronic acid is used for diagnostic purposes. Tetrasodium salt of butedronic acid is bone imaging agent.

(R)-3'-hydroxybutyl (R)-3'-hydroxybutyrate or D-β-hydroxybutyrate ester is a is an effective and palatable precursor to the ketone body. Ketone bodies are the most energy-efficient fuel and yield more ATP per mole of substrate than pyruvate and increase the free energy released from ATP hydrolysis. Ketone diet containing (R)-3-hydroxybutyl (R)-3-hydroxybutyrate, improved physical performance and cognitive function in rats, and its energy-sparing properties suggest that it may help to treat a range of human conditions with metabolic abnormalities. It may be used to treat a condition which is caused by, exacerbated by or associated with elevated plasma levels of free fatty acids in a human or animal subject, for instance a condition where weight loss or weight gain is implicated, or to promote alertness or improve cognitive function, or to treat, prevent or reduce the effects of, neurodegeneration, free radical toxicity, hypoxic conditions or hyperglycaemia. It has been approved by the FDA as “Generally Regarded as Safe (GRAS)”.
