Cinecromen is benzopyranone derivative useful as coronary dilators. Cinecromen increases dog coronary blood flow two times after i.v. administration.

Ceftioxide is broad-spectrum , beta-lactam antibiotic patented by German pharmaceutical company Hoechst A.-G.

Cefuroxime Pivoxetil is an ester prodrug of cefuroxime, a semisynthetic, broad-spectrum, beta-lactamase-resistant, second-generation cephalosporin with antibacterial activity. Cefuroxime binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

Dimenoxadol is an opioid analgesic which produces typical opioid effects such as analgesia and sedation. It is structurally similar to methadone and is a benzilic acid derivative. In the United States it is classified as a Schedule I controlled drug.

The new chemical entity KC12615 is a potent f neutral endopeptidase inhibitor with additional endothelin-converting enzyme (ECE)–inhibitory activity.2 KC12615 is the hydrolyzed form of the oral prodrug SLV306 (daglutril). In plasma, the compound increases natriuretic peptide levels and prevents the formation of endothelin-1 by inhibiting the degradation of its precursor, big endothelin. It is investigated for use/treatment in congestive heart failure and hypertension.

Proxicromil is substituted chromone patented in the late 1970s by Fisons Ltd. for the treatment of allergic asthma. Proxicromil acts on to FcεRIreceptor in mast cells, thereby inhibiting the production of histamines. Proxicromil is tested through a variety of independent studies for its beneficial effect as an anti-allergen, its efficacy against migraine, asthma and tumor enhancement. It shows no effect as a prophylactic against migraine. The reported side effects during this study related mainly to transient gastrointestinal troubles and were generally of a mild nature. For asthma and exercise-induced bronchospasm, Proxicromil was found to be mildly effective. But the investigation was discontinued when malignancies occurred in long-term animal studies.

Dexetozoline is a safe and effective diuretic agent in the treatment of acute cardiac failure. In isolated rings of guinea-pig aorta not responding to acetylcholine, the diuretic dexetozoline did not influence basal vascular tone but inhibited noradrenaline- and histamine-induced contractions. Dexetozoline has a very high bioavailability after oral administration and is fairly lipohilic. The half-life of etozolin is 2.5 h. Dexetozoline accumulates in cirrhosis.

Danegaptide (GAP-134) is a small dipeptide gap junction modifier, developed by Wyeth and Zealand Pharma. Danegaptide works by re-establishing of gap junction intercellular communications in adjacent cardiomyocytes, thus reversing cardiac conduction slowing and electrical heterogeneity thought to be responsible for arrhythmias. In a canine model of acute sterile pericarditis, Danegaptide significantly reduced AF duration and overall AF burden. Danegaptide was investigated in phase 2 clinical trial in patients with ST-segment elevation myocardial infarction (STEMI). It was found that administrations danegaptide to patients with STEMI did not improve myocardial salvage, and development of the drug was discontinued.
