Fosfocreatinine, a cardioprotectant that was used for the treatment of cardiac disorders. Information about the current use of this drug is not available.

Nicoclonate is a nicotinic acid derivative. It is an antilipidemic drug.

Doxpicomine is the hydrochloride salt of l-3[(dimethylamino)-(m-dioxan-5-yl)methyl]pyridine, a derivative of substituted 1,3 dioxanes. Its analgesic effect appears to be mediated centrally through opiate-like receptors. Preclinical animal studies revealed analgesic activity and duration of action of the same order as that of meperidine and codeine when administered subcutaneously and of codeine but of shorter duration when administered orally. The analgesic effects were reversed by naloxone. The drug did not reduce or antagonize the analgesic effect of morphine. Drowsiness is an expected response to effective analgesics. It was the foremost side effect observed but was of short duration and minimal intensity and did not interfere with the postoperative regimen of coughing, deep breathing, and early ambulation. Nausea and vomiting were not reported after doxpicomine.

Osmadizone was investigated as a uricosuric agent. Information about the current use of this compound is not available.

FLUMEXADOL is a non-opioid analgesic. Its prodrug OXAFLOZANE was used as an antidepressant in France till 2004.

Ragaglitazar (DRF 2725, NNC 61-0029) is phenoxazine analog of phenyl propanoic acid having dual (PPARα and PPARγ) agonist property intended to restore insulin sensitivity and correct diabetic dyslipidemia. PPAR-α is highly expressed in liver and muscle and upon activation leads to decreases in plasma triglycerides and increases in HDL cholesterol levels. PPAR-γ activation leads to enhancement of glucose uptake in skeletal muscles and adipose tissue. Ragaglitazar provided the glycemic control that was comparable with that of pioglitazone and, compared with placebo, provided a significant improvement in the lipid profile.

Oxetacillin was developed as an antibacterial drug that has never been marketed.

Salirasib or S-trans,trans-Farnesylthiosalicylic acid (FTS) is a salicylic acid derivative with potential antineoplastic activity. It acts as a potent competitive inhibitor of the enzyme prenylated protein methyltransferase (PPMTase), which methylates the carboxyl-terminal S-prenylcysteine in a large number of prenylated proteins including Ras. In such systems, Salirasib inhibits Ras methylation but not Ras farnesylation. Salirasib selectively disrupts the association of chronically active Ras proteins with the plasma membrane. Salirasib competes with Ras for binding to Ras-escort proteins, which possess putative farnesyl-binding domains and interact only with the activated form of Ras proteins, thereby promoting Ras nanoclusterization in the plasma membrane and robust signals. Salirasib was studied in the clinical trials in patients with solid tumors, however its development was discontinued.

Butafosfan is a phosphororganic supplement that is given, most commonly with cyanocobalamin, to cattle, swine, horses, and poultry for the prevention or treatment of phosphorus deficiencies. Butafosfan also plays a vital role in hepatic carbohydrate metabolism. In addition, butafosfan has been regarded as an antistress agent in combination with vitamin B12. Studies with butafosfan in different animals have shown that it improved general health status by stimulating feed intake, immune system, and digestive function. Butafosfan has been reported for the treatment of metabolic disorders caused by stress or nutrition problems in various species.
