Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 / dopamine D2 blocking activity. It is not available in the US but marketed in other countries for prophylaxis of a migraine, occlusive peripheral vascular disease, the vertigo of central and peripheral origin, motion sickness and as an adjuvant in the therapy of epilepsy. The drug is also investigated for the treatment of schizophrenia.

Peplomycin has been developed as novel analog of bleomycin, which has less pulmonary toxicity than bleomycin. Peplomycin has been the subject of extensive studies in Japan and Europe. It is indicated for the treatment of malignant lymphoma, head and neck cancer, lung cancer, prostate cancer and skin cancer. General side effects are: digestive symptoms such as stomatitis, anorexia, nausea/vomiting, general malaise, depilation, fever, chills etc.

Zofenopril is an inhibitor of Angiotensin Converting Enzyme (ACE), which is approved in Europe for the treatment of hypertension and acute myocardial infarction.

Cilazapril (Vascace and Dynorm are brand names in a number of European countries) is an angiotensin converting enzyme (ACE; kininase II) inhibitor. It competes with angiotensin I for binding at the angiotensin-converting enzyme, blocking the conversion of angiotensin I to angiotensin II. Cilazapril is a prodrug that is hydrolyzed after absorption to its main metabolite cilazaprilat. The half-life (30–50 hours) of cilazapril allows for once daily dosing unless the hypertension is severe. Cilazapril is used for the treatment of hypertension, congestive heart failure, post-myocardial infarction, and some other indications. Adverse events were mostly observed within the first 8-16 weeks of treatment, with headache, dizziness, fatigue, nausea, cough and chest pain being the most frequent.

Fosfonet sodium (or phosphonoacetate sodium), an organophosphorus compound, was found to be a specific inhibitor of the virus-induced DNA polymerases and thus could inhibit specifically the replication of herpes-viruses.

Melitracen (HCl) is a tricyclic antidepressant with actions and effects similar to amitriptyline.Melitracen (HCl) is given orally in the treatment of depression. It should be withdrawn gradually to reduce the risk of withdrawl symptoms. Melitracen (HCl) is primarily indicated in conditions like Anxiety, Asthenia, Depression, gastro-intestinal disorders associated with anxiety and agitation. Melitracen is marketed in Europe and Japan by Lundbeck and Takeda, respectively, for the treatment of depression and anxiety. In addition to single drug preparations, it is also available as Deanxit, a combination product containing both melitracen and flupentixol. The way this drug works hasn’t been thoroughly researched, but some hypothesize that it may work similarly to the drugs Imipramine and Amitriptyline. In comparison to older TCAs, this drug is thought to work more quickly with more favorable side effects.

Adinazolam, a benzodiazepine agonist, is an effective anxiolytic agent with antidepressant properties. It was shown, that adinazolam by itself had relatively weak benzodiazepine agonist activity, and much of the pharmacological activity belonged to its active metabolite N-desmethyladinazolam (NDMAD). Adinazolam has never been FDA approved, but it is sold as a research chemical.

Reproterol is a short-acting β2 adrenoreceptor agonist used in the treatment of asthma. Reproterol increases the generation of cAMP in isolated peripheral blood monocytes in vitro more effectively than does orciprenaline. In the presence of the highly potent but nonselective ß-antagonist, propranolol, the cAMP-generating action of reproterol was inhibited only partially. Reproterol has gained wide use when it was licensed as a fixed combination therapy with cromoglycate. Until today, the bronchodilator effects of reproterol and the bronchoprotective and anti-inflammatory actions of cromoglycate combined in one inhaler remain the successful fixed combination of a disease-modifying and symptomatic drug for the treatment of asthma.

Carumonam is a monobactam antibacterial agent. It was highly active in vitro against members of the family Enterobacteriaceae, Pseudomonas aeruginosa, and Haemophilus influenzae and weakly active against Streptococcus pneumoniae, but it was not active against Staphylococcus aureus. The excellent activity of carumonam against Gram-negative bacteria is related to its high affinity for their penicillin-binding proteins. It is indicated for the treatment of urinary tract infections, chronic respiratory infections, biliary tract infections, peritonitis, sepsis. Another factor that contributes to the excellent activity of carumonam against Gram-negative bacteria is its resistance to beta-lactamases. Adverse effects of the carumonam were limited to phlebitis at the intravenous infusion site; bloody diarrhea.

Stibogluconic acid (Sodium stibogluconate) is the pentavalent antimonial compound used to treat leishmaniasis and is only available for administration by injection. Sodium stibogluconate is sold in the UK as Pentostam (manufactured by GlaxoSmithKline). Sodium stibogluconate was granted orphan drug designation for the treatment of cutaneous leishmaniasis by the US FDA in January 2007. It is available in the United States only through the Centers for Disease Control. Sodium stibogluconate is indicated for the treatment of various types of a protozoal infection called leishmaniasis, which may result from sandfly bites in tropical and temperate parts of the world. It is also investigated for use/treatment in cancer. The mode of action of sodium stibogluconate is not clearly understood. In vitro exposure of amastigotes to 500 mg pentavalent antimony/ml results in a greater than 50% decrease in parasite DNA, RNA protein and purine nucleoside triphosphate levels. It has been postulated that the reduction in ATP (adenosine triphosphate) and GTP (guanosine triphosphate) synthesis contributes to decreased macromolecular synthesis. Sodium stibogluconate was shown to specifically inhibit type I DNA topoisomerase from Leishmania donovani through the inhibition of the unwinding and cleavage of the supercoiled plasmid pBR322, and to stabilize topoisomerase and DNA covalent complexes but not calf-thymus topoisomerase I and Escherichia coli DNA gyrase. Sodium stibogluconate is also a potent inhibitor of PTPases Src homology PTPase1 (SHP-1), SHP-2, and PTP1B but not the dual-specificity phosphatase mitogen-activated protein kinase phosphatase 1. Sodium stibogluconate combined with IFN-alpha-2b (IFN-α) inhibited solid tumor cell line growth in vitro, in vivo it was well tolerated and augmented cellular immune parameters.
