FENIMIDE, a succinimide derivative, is an antipsychotic drug. It is not found in any pharmaceutical preparations sold in the US. It was found that FENIMIDE produced a sedative effect prior to deeper central nervous system depression.

Butoprozine increased the action potential duration like amiodarone, depressed the plateau phase like verapamil and decreased the amplitude and the maximum rate of depolarization. Butoprozine injected intravenously depressed sino-atrial node function, lengthened A-V nodal conduction time and the A-V nodal refractory period, and prolonged the atrial refractory period. Thus butoprozine acted preferentially on parts of the myocardial tissue where the slow inward current seems to be particularly involved. In this respect, butoprozine was more active than amiodarone, but in contrast to this drug, butoprozine did neither prolong the ventricular monophasic action potential duration nor the ventricular refractory period.

Esorubicin (4'-deoxydoxorubicin, NSC 267469) is a synthetic derivative of the anthracycline antineoplastic antibiotic doxorubicin with potential antineoplastic activity. Esorubicin intercalates into DNA and inhibits topoisomerase II, thereby inhibiting DNA replication and ultimately, interfering with RNA and protein synthesis. This agent exhibits less cardiotoxicity than the parent antibiotic doxorubicin, but may cause more severe myelosupression compared to other compounds within the anthracycline class. Esorubicin was being clinically tested for the treatment of solid tumors as well as lymphomas an leukemias. Esorubicin development has been discontinued.

Cuprimyxin is a topical antibiotic with considerable antibacterial, anti-yeast, and antifungal activity in veterinary applications without the irritation side effects. Cuprimyxin was formulated in cream and tested in vitro against Gram-positive and Gram-negative bacterial and fungal pathogens and yeast infections, in vivo as a cream for otic and ophthalmic infections, and as a suspension with hydrocortisone acetate for the treatment of otitis. The apparent biological mechanism of action involves alteration of the invading bacterial DNA template

Betamethadol or β-methadol is an opioid analgesic under international control according to the UN Single Convention 1961. Betamethadol is an isomer of the racemic mixture of dimepheptanol.

Nuclotixene is an antidepressive agent.

Bepafant (also known as WEB-2170), an inverse agonist of platelet-activating factor receptor that has been preclinical studied in asthma, Ischemic heart disorder and in reperfusion injury after orthotopic liver transplantation. However, these studies were discontinued. Besides, several experiments have shown that bepafant induced apoptosis in human acute myelogenous leukemia and thus could be the powerful antileukemic agent.

Tinisulpride is a sulfamoylbenzoic acid patented by Fabre, Pierre, S. A. as an antiemetic agent.

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.
