Stenbolone is an anabolic–androgenic steroid of the dihydrotestosterone group patented by Schering AG but never marketed. Ester prodrug of stenbolone is used as an anabolic–androgenic steroid for depot intramuscular injection under the brand names Anatrofin and Stenobolone.

Ibuverine was studied as an antispasmodic agent. Information about the current use of this drug is not available.

Norcodeine is the N-demethylated derivative of codeine. It has relatively little opioid activity in its own right, but is formed as a metabolite of codeine following ingestion. Codeine and its other major metabolites codeine-6-glucuronide and norcodeine have weak affinity to opioid μ-receptors.

Rostafuroxin (PST 2238) is a digitoxygenin derivative, which selectively displaces ouabain from the Na ,K -ATPase receptor. PST 2238, at concentrations up to 10−4 M, did not show any significant interaction with a- and b-adrenergic, D1, D2, D3, 5-HT1, 5-HT2, H1, H2, M1, M2, A1, A2, Ca2 , Na , or K channel–associated receptors, AT1, AT2, ETa, ETb, GABA, thromboxane, vasopressin, angiotensin II, or the steorid-hormone receptors (androgen, progestogen, estrogen and mineralocorticoid), confirming that PST 2238 is specific for Na ,K -ATPase. Rostafuroxin has been developed in an attempt to unravel the contribution of mutated adducin and endogenous ouabain in the pathogenesis of hypertension. The compound lowered blood pressure in Milan hypertensive rats and humans. Rostafuroxine had been in phase II clinical trials for the treatment of hypertension. Following adverse events in Rostafuroxin group were described: dizziness, headache, upper respiratory tract infections, high blood pressure.

Nemadectin (LL-F28249-a) is a macrocyclic lactone antibiotic demonstrating broad-spectrum endectocidal and nematocidal activity. Nemadectin, the dominant member of a class of milbemycins bearing unsaturated longer chain group at the C25 position, is commonly used as a starting material for the commercial anthelmintic moxidectin.

Misonidazole is a nitroimidazole with radiosensitizing and antineoplastic properties. Exhibiting high electron affinity, misonidazole induces the formation of free radicals and depletes radioprotective thiols, thereby sensitizing hypoxic cells to the cytotoxic effects of ionizing radiation. This single-strand breaks in DNA induced by this agent result in the inhibition of DNA synthesis. The drug also possesses a substantial cytotoxic effect, independent of radiation, which is selectively expressed in hypoxic cells. Misonidazole may be cytotoxic to the normal hypoxic tissues in the human body, making this became a major concern in the clinical application of the drug. Misonidazole leads to strand breaks in cellular DNA and those cells which fail to survive also fail to repair these strand breaks. Misonidazole depletes intracellular glutathione and is more toxic in glutathione depleted cells.

Mebolazine is an androgenic anabolic steroid.

Stevaladil is a pregnanediol derivative patented by Shionogi & Co., Ltd. as antiparasitic agent
