Icopezil (previously known as CP-118,954) was developed as a selective acetylcholinesterase inhibitor for the treatment of cognitive disorders. Phase II trials of icopezil were underway in Japan and in the USA for the treatment of patients with Alzheimer's disease. However, Pfizer has discontinued these studies.

Bensuldazic acid was used in veterinary as an antifungal agent.

Edonentan (BMS 207940) is a highly selective biphenylsulfonamide endothelin A receptor antagonist. (11)C- and (18)F-labeled analogs of edonentan were evaluated of novel PET radioligands for imaging the endothelin-A receptor. Edonentan was in clinical trials for the treatment of heart failure however its development has been discontinued.

Benzindopyrine belongs to anticholinergic agents. It was studied as an antipsychotic drug.

Remogliflozin is the active component of the pro-drug remogliflozin etabonate, which is used the treatment of non-alcoholic steatohepatitis ("NASH") and type 2 diabetes. Remogliflozin inhibits the sodium-glucose transport proteins (SGLT), is selective for SGLT2, which is responsible for glucose reabsorption in the kidney. Blocking this transporter causes blood glucose to be eliminated through the urine.

Tecarfarin (also known as ATI-5923), an anticoagulant, is a vitamin K reductase antagonist. Tecarfarin is participating in phase III clinical trials for the treatment of thromboembolism and thrombosis. On March 11, 2019, Espero BioPharma Inc. announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) for tecarfarin for the prevention of systemic thromboembolism of cardiac origin. Tecarfarin is metabolized by esterases, escaping metabolism by the cytochrome P450 system and thereby avoiding cytochrome P450-mediated drug-drug or drug-food interactions as well as genetic variations found in the cytochrome P450 system.

Sulfinalol is a hydroxyphenylalkanolamine derivative patented by Sterling Drug Inc. as the antiarrhythmic, antihypertensive, vasodilating, and adrenergic agent. Oral administration of sulfinalol reduces the pressure of conscious spontaneously hypertensive rats. Antihypertensive action of sulfinalol was inhibited by propranolol pretreatment. Sulfinalol demonstrates effective beta-adrenergic blockade at the antihypertensive dose tested as judged by inhibition of the chronotropic responses to sympathetic stimulation and isoproterenol in pithed rats. In the renal hypertensive dog. sulfinalol lowered both systolic and diastolic blood pressure to normal values with an only slight change in heart rate.

Metalkonium is an antiseptic and disinfectant.

Pyrroliphene is a dialkylaminodiphenylbutanol ester with antitussive and analgesic activities. In clinical trials the major side effect of Pyrroliphene was sedation, and the other side effect liabilities were similar to those of morphine.

Deterenol is a beta-adrenoceptor agonist. It is an effective nonmydriatic and nonmiotic hypotensive agent, which can be used in antiglaucoma treatment.
