Mercurobutol is an antiseptic and disinfectant. Mercurobutol exhibits fungistatic and fungicidal activities.

Afeletecan (Bay 38-3441) is a camptothecin glycoconjugate which stabilizes the active lactone form of camptothecin and allows selective uptake into tumor cells. Afeletecan is a topoisomerase inhibitor. Afeletecan was in phase I clinical trials with Bayer for the treatment of cancer; however, development appears to have been discontinued.

Coumazoline is a vasoconstrictor developed as a nasal decongestant by a French corporation Labez. Intravenous administration of the compound to dogs lead to a marked and prolonged drop in the temperature of the gingival mucosa. In rats, coumazoline caused slowing of the dye diffusion on the surface of the skin. The compound did not influence the ciliary motility, as was measured on an isolated guinea pig trachea.

Sabarubicin (previously known as MEN-10755), a disaccharide analog of doxorubicin that was developed by Menarini Pharmaceuticals for the treatment of solid tumors, including small cell lung cancer and prostate cancer. Sabarubicin exhibits a superior antitumor efficacy, presumably related to the activation of p53-independent apoptosis. The drug participated in phase II clinical trials to study its effectiveness in treating patients who have progressive prostate cancer that has not responded to hormone therapy and in chemotherapy-naive patients with extensive stage small cell lung cancer. On 21 December 2004, the European Commission granted the orphan designation to Menarini for sabarubicin for the treatment of small cell lung cancer.

Homocysteine, an amino acid synthesized intracellularly by removal of the N-methyl group from the essential amino acid methionine. High plasma level of homocysteine is called hyperhomocysteinemia is a clinical biomarker for increased risk of cardiovascular disease, thromboembolic diseases, and myocardial infarction. It was shown, that hyperhomocysteinemia could be an independent risk factor for dementia and Alzheimer's disease. The falling of homocysteine concentrations in response to increasing B-group-vitamin status, have the hope that mental decline, or Alzheimer's disease, could be prevented by dietary modification or food fortification. Besides, homocysteine can behave as an anti-oxidant agent by increasing the antioxidant capacity of the tumor and endothelial cells.

Ioxabrolic Acid is triiodobenzoic acid derivative and iodine-containing radiopharmaceutical

Norleucine (L-norleucine) is a 2-aminohexanoic acid is an alpha-amino acid that is caproic acid substituted by an amino group at position 2. It derives from a hexanoic acid. It is used experimentally to study protein structure and function. Norleucine appears to inhibit bacterial growth due to incorporation into proteins in place of methionine, as the analogue inhibits methionine incorporation but does not significantly reduce its synthesis. L-norleucine had antiviral activity in thermophile. In vitro and in vivo assays revealed that L-norleucine significantly suppressed metastasis of gastric and breast cancer cells. L-norleucine interacted with hnRNPA2/B1 protein to inhibit the expressions of Twist1 and Snail, two inhibitors of E-cadherin, and promote the E-cadherin expression, leading to the inhibition of tumor metastasis.

Cinaproxen is naproxen derivative developed by Nicox S.A. for oxidative stress prevention and treatment.

Inicarone is benzofuryl derivative with potent antifibrinolytic activity.

Racemethorphan is racemic mixture of Dextromethorphan and Levomethorphan. Racemethorphan is listed under the Single Convention on Narcotic Drugs 1961 and is therefore listed in the United States as a Controlled Substance, specifically as a Narcotic in Schedule II. Dextromethorphan is a non-narcotic morphine derivative widely used as an antitussive. Dextromethorphan is a cough suppressant in many over-the-counter cold and cough medicines. In 2010, the FDA approved the combination product dextromethorphan/quinidine for the treatment of pseudobulbar affect. Dextromethorphan suppresses the cough reflex by a direct action on the cough center in the medulla of the brain. Levomethorphan is an opioid analgesic of the morphinan family that has never been marketed.
