Omonasteine was used in sequential peptide ligation for the synthesis of the BRD7 bromodomain.

Cefedrolor is a broad-spectrum cephalexin antibiotic patented by pharmaceutical company Bristol-Myers Co.

Vidupiprant, also known as AMG 853, is an orally bioavailable and potent dual antagonist of the D-prostanoid and chemoattractant receptor-homologous molecule expressed on T helper 2 cells receptors. Vidupiprant inhibits PGD2-induced down modulation of CRTH2 on CD16- granulocytes in human whole blood as well as PGD2-induced cAMP response in platelets. It inhibits PGD2-induced airway constriction in vivo. Also inhibits BRD4 (Kd = 170 nM). AMG 853 as an add-on to inhaled corticosteroid therapy demonstrated no associated risks but was not effective at improving asthma symptoms or lung function in patients with inadequately controlled moderate-to-severe asthma. AMG 853 has been discontinued due to poor efficacy.

Rotigaptide (previously known as ZP123) originally was developed by Zealand Pharma as a stable antiarrhythmic peptide analog, which maintains gap junction intercellular communication. Then this drug was licensed to Wyeth Pharmaceuticals where it studied in phase II clinical trials in patients with coronary artery disease and with atrial fibrillation. However, these researches have been discontinued.

Benurestat is a urease inhibitor, which as was shown in experiments on rats, could decrease in the urinary excretion of ammonia with experimental P. mirabilis genitourinary tract infection.

Actodigin is a semisynthetic cardiac glycoside compounded from digitoxigenin and one molecule of glucose. In addition, unlike the naturally occurring glycosides, the C-2 instead of the C-3 atom of the lactone ring is attached to the steroid nucleus. Actodigin is a cardiovascular agent. When injected at 30 min invervals into dogs with barbiturate-induced heart failure, actodigin caused a marked positive inotropic action of short duration. It converted arrhythmia to normal sinus rhythm. Actodigin effectively and quickly reduced the ventricular rate in patients with atrial fibrillation. Actodigin, because of its rapid onset and brief duration of action, may be useful in controlling the ventricular rate in patients with atrial fibrillation.

Amicibone is an antitussive agent.

Amicycline is an anti-bacterial agent, an antibiotic of tetracycline class.

Dextofisopam, a non-serotonergic agent currently being evaluated for the treatment of irritable bowel syndrome (IBS), is the R-enantiomer of racemic tofisopam, a molecule marketed and used safely outside the United States for over three decades for multiple indications including IBS. Dextofisopam represents a novel, first-in-class opportunity with a positive proof-of-concept study in an arena where there are few compounds with unique approaches or positive efficacy results. By structure, Dextofisopam is a member of the homophthalazine class; Dextofisopam binds to specific receptors in areas of the brain affecting autonomic function, including gastrointestinal (GI) function. Unlike the two 5-HT3 or 5-HT4 mediated IBS therapies currently available, both with significant safety concerns, Dextofisopam novel non-serotonergic activity offers a unique and innovative approach to IBS treatment. Recent studies have indicated that dextofisopam binds to a novel binding site within the central nervous system that may be responsible for mediating its actions. This receptor has been characterized as the 2,3-benzodiazepine receptor, which is distinct from the classical 1,4 or 1,5-benzodiazepine receptor. Dextofisopam has no significant binding at other receptors or ion channels

Cianopramine is a highly potent inhibitor of neuronal serotonin (5-HT) uptake developed by Hoffmann-La Roche for major depression treatment. In preclinical studies, acute and chronic treatment with Cianopramine shows clear behavioural effects Cianopramine increases neophobic reactions in the free exploration test, the avoidance reaction to a brightly illuminated chamber in the light/dark choice procedure as well as to open arms in the elevated plus-maze test. In a double-blind trial, Cianopramine effective in reducing scores on the Hamilton Psychiatric Rating Scale for Depression and on a global scale. Unfortunately, Cianopramine administrations were associated with significant adverse effects and future development was discontinued.
