Amineptine is a selective inhibitor of dopamine reuptake. The drug was developed in France and was marketed for the treatment of depressive disorders under the name Survector among the others. Amineptine was withdrawn from the French market in 1999 because of abuse and drug dependence and because of its hepatic (cholestatic injuries) and cutaneous (acne) adverse effects.

Satraplatin is a fourth-generation platinum-based anticancer drug developed by GPC Biotech, Inc. Unlike its predecessors cisplatin and carboplatin, which were administered intravenously, satraplatin was developed for oral administration. Satraplatin mediates its action through the formation of DNA adducts and inter- and intra-strand crosslinks. These adducts distort the DNA template with a deceleration of cells in S phase followed with G2 phase arrest. Satraplatin also inhibits DNA replication and transcription and induces signal transduction pathway, leading to cell cycle arrest and apoptosis. Satraplatin was investigated in phase III clinical trials against metastatic castrate-resistant prostate cancer. Despite the improvement in progression-free survival and palliation, overall survival was not improved with satraplatin therapy. The median survival was 61.3 weeks in the satraplatin group and 61.4 weeks in the prednisone and placebo group. In July 2007, GPC Biotech announced the withdrawal of the New Drug Application (NDA) for satraplatin, and the development of the drug was discontinued.

Zipeprol is disubstituted piperazine that is marketed as a non-opioid antitussive in Europe, Asia, and South America. Zipeprol is not available in the United States or Canada and has been discontinued in Europe. Zipeprol is still available in some countries in Asia and South America. Zipeprol was demonstrated to have anticough effects in animal models, to be active as a blocker of histamine and cholinergic function, to be a potent local anesthetic and to possess bronchiospasmolytic actions. it had no remarkable cardiovascular or gastrointestinal actions in the rat or dog in comparison to codeine.

Pleconaril (Picovir) is an antiviral drug that was being developed by Schering-Plough for prevention of asthma exacerbations and common cold symptoms in patients exposed to picornavirus respiratory infections. Pleconaril binds to a hydrophobic pocket in viral protein 1, the major protein which comprises the capsid (the outer "shell") of picornaviruses. In enteroviruses, this prevents the virus from exposing its RNA, and in rhinoviruses, it also prevents the virus from attaching itself to the host cell. The results of two randomized, double-blind, placebo studies found Pleconaril treatment could benefit patients suffering from colds due to picornaviruses. Participants in the studies were healthy adults from Canada and the United States, with self-diagnosed colds that had occurred within 24 hours of trial enrollment. Participants were randomly given a placebo or two 200 mg tablets to take three times daily for five days. To increase absorption it was recommended to be taken after a meal. To monitor the effectiveness of Pleconaril, Participants recorded the severity of their symptoms and nasal mucosal samples were obtained at enrollment, day 3, day 6 and day 18. The two studies had a total of 2096 participates and more than 90% (1945) completed the trial. The most common reason for a participant not finishing the trial was an adverse event. Pleconaril treatment showed a reduction in nose blowing, sleep disturbance, and less cold medication used. The U.S. Food and Drug Administration rejected pleconaril in 2002 due to the side effects. The most commonly reported side effects were mild to a moderate headache, diarrhea, and nausea.

Raltitrexed belongs to a group of medicines known as antimetabolites. It is used to treat cancer of the colon and rectum. It may also be used to treat other kinds of cancer, as determined by your doctor. Raltitrexed blocks an enzyme needed by the cell to live. This interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by raltitrexed, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Raltitrexed inhibits thymidylate synthase (TS) leading to DNA fragmentation and cell death. It is transported into cells via a reduced folate carrier. Inside the cell Raltitrexed is extensively polyglutamated, which enhances thymidylate synthase inhibitory power and duration. Inhibition of this enzyme results in decreased synthesis of thymidine triphosphate which is required for DNA synthesis. Raltitrexed is used for the treatment of malignant neoplasm of colon and rectum. Although raltitrexed is not approved by the US FDA, the drug was licensed in Canada and some European countries.
