Pirogliride is the antidiabetic agent. It has been found to produce a hypoglycemic effect in nondiabetic rats, dogs, mice, and monkeys. To being three to four times more potent than tolbutamide, pirogliride also differs from the sulfonylureas in lowering blood glucose concentrations of streptozotocin-diabetic rats and db/db mice, and, moreover, oral administration to normal fasted dogs did not produce the characteristic rise in insulin concentrations observed with tolbutamide. Pirogliride potentiates glucose-induced insulin secretion from isolated islets. This effect is accompanied by a facilitated glucose metabolism. Pirogliride partially prevents the known inhibitory effects of mannoheptulose on glucose-induced secretion and utilization. Pirogliride was found to produce a concentration-dependent inhibition of gluconeogenesis in rat kidney cortex slices. hepatocytes and perfused liver. Pirogliride was metabolized in man to a small extent by oxidation of the 4-position of the phenyl ring.

Tametraline (also known as CP-24,441) is a norepinephrine-dopamine reuptake inhibitor that was developed as an Antidepressant agent. Information about the current use of this drug is not available.

Cypenamine (2-phenylcyclopentylamine) is a psychostimulant and antidepressant drug developed at William S. Merrell Chemical Company.

Sulisatin (also known as DAN-603) is an indolinone derivative patented by Andreu, Dr., S. A. as a laxative. In preclinical models, Sulisatin increases selectively the colon motility without modifying the speed of gastric, intestinal (small intestine) and caecal emptying in rats. Sulisatin is unable to inhibit water absorption in rat colon while small amounts of Sulisatin may inhibit it significantly.

Asulacrine, also known as CI-921, an inhibitor of topoisomerase II, participated in clinical trials phase II for the treatment of cancer. In spite of the positive and promising results, this drug showed the toxicity, phlebitis that blocks its implementation in the future.

Asoprisnil (J867) is a novel selective steroid receptor modulator that shows unique pharmacodynamic effects in animal models and humans. Asoprisnil, its major metabolite J912, and other structurally related compounds represent a new class of progesterone receptor (PR) ligands that exhibit partial agonist and antagonist activities in vivo. Asoprisnil demonstrates a high degree of receptor and tissue selectivity, with a high-binding affinity for PR, moderate affinity for glucocorticoid receptor (GR), low affinity for androgen receptor (AR), and no binding affinity for estrogen or mineralocorticoid receptors. This compound was recently in clinical trials for the treatment of uterine fibroids and endometriosis, but those studies were discontinued.

Flavodic acid is a synthetic hydrosoluble derivative of natural flavonoids. It has been shown to reduce capiliary fragility and permeability. Sodium flavodate was marketed by the Italian pharmaceutical company Farmaceutici under tradename Pericel.

Roxifiban (also known as DMP754), a potent antiplatelet agent in inhibiting platelet aggregation, and has a high specificity and affinity for human platelet glycoprotein IIb/IIIa complex (GPIIb/IIIa) receptors. Roxifiban participated in clinical trials phase III for the treatment of peripheral arterial disorders. This drug was also well tolerated in patients with chronic stable angina pectoris and was studied in the treatment of heparin-induced thrombocytopenia, and thrombosis. However, the development of this drug appears to have been discontinued.

Butinoline (also known as azulone) was used as an antispasmodic drug to treat gastritis.

Temanogrel (also known as APD791) is an oral small molecule inverse agonist of the serotonin 2A (5-HT2A) receptor with potent activity on platelets and vascular smooth muscle. Temanogrel has been studied in phase I clinical trials in healthy subjects to assess its pharmacokinetics, pharmacodynamics, and safety. However, these studies were terminated because of the sponsor’s decision.
