Amiprilose hydrochloride (brand name Therafectin), a novel synthetic carbohydrate with anti-inflammatory properties, which was developed for the treatment of rheumatoid arthritis. In September 1993, FDA informed that this drug could not be approved because there was not adequate data demonstrating the drug’s effectiveness.

ISAMFAZONE is a non-steroidal antiinflammatory, analgesic agent.

Ciprostene is a synthetic, chemically stable analog of prostacyclin (PGI2). In animal models, administration of ciprostene resulted in dose-dependent hypotension, tachycardia, and inhibition of ex vivo ADP-induced platelet aggregation. Ciprostene was evaluated in clinical trials in patients with peripheral vascular disease. It was found to reduce restenosis in patients with coronary artery disease undergoing therapeutic percutaneous transluminal coronary angioplasty.

Somantadine, an adamantane derivative, is an antiviral agent. Somantadine was synthesized by Pennwalt and has been undergoing tests for the treatment of herpes virus for nearly five years.

Mociprazine is a piperazinyl(propargyloxy)propanol derivative with antiemetic activity.

FEPRADINOL is an analgesic, antipyretic and anti-inflammatory agent. Its anti-inflammatory activity does not seem to be related to an inhibitory effect on prostaglandin biosynthesis.

Imoxiterol (also known as RP 58802B) is benzimidazole derivatives patented by pharmaceutical company Laboratoire Roger Bellon S. A as a long-acting β-adrenergic agonist. In preclinical models, nebulized Imoxiterol produced a rapid onset and long-lasting inhibition of histamine-induced bronchospasm in the anaesthetized guinea-pig. Given orally, Imoxiterol produced a greater than three-fold shift to the right of the dose-response curve and depressed the maximum response to histamine. Imoxiterol prevented the development of bronchial hyperreactivity. Although PAF-induced bronchial hyperreactivity was not accompanied by an increase in the number of pulmonary eosinophils, Imoxiterol reduced the numbers of eosinophils recovered by lavage. Imoxiterol significantly inhibited PAF-induced microvascular leakage into guinea-pigs lung.

Dextrofemine is the (+)-form of racefemine. It is antispasmodic agent. Dextrofemine was used as utrine spasmolytic or muscle relaxant.

Naxaprostene (CG 4305) is a prostacyclin analogue, which causes concentration dependent inhibition of thrombocyte function. Naxaprostene is more selective for IP receptors and tends towards partial agonism. Naxaprostene prevented thrombotic arterial occlusion in rabbits.

Dicirenone is an aldosterone antagonist. It is used as a hypotensive agent. Dicirenone inhibited the effects of aldosterone on urinary K(+):Na(+) ratios and the binding of [(3)H]aldosterone to renal cytoplasmic and nuclear receptors. Dicirenone blocked the action of aldosterone on Na-K ATPase. Cytoplasmic binding of [(3)H]aldosterone and dicirenone was similar in magnitude and involved the same set of sites. It had no effect on adrenal steroidogenesis.
