Nikkomycin Z is an antifungal drug that inhibits chitin synthase. It has been reported that it inhibits chitin synthases (Chs) 1 and 3, but not 2, of Saccharomyces cerevisiae. Later it was found that nikkomycin Z inhibited all three Chs isozymes of Candida albicans (CaChs). The IC(50) value for CaChs1 is 15 uM, for CaChs2 0.8 uM, and for CaChs3 13 uM. Nikkomycin Z is under development as an orphan product for treatment of coccidioidomycosis. Nikkomycin Z has been used in trials studying the treatment and basic science of Coccidioidomycosis. In February 2006, nikkomycin z was designated as an orphan drug for the treatment of Coccidioidomycosis.

ISOPROFEN is an anti-inflammatory agent with analgesic and antipyretic properties. Its anti-inflammatory potency is greater than that of phenylbutazone but lower than that of indomethacin. Its antipyretic action can be explained by an effect of this substance on the metabolism of arachidonic acid in the brain.

Pancopride (LAS 30451) is a 5-hydroxytryptamine 3 receptor antagonist and was developed against cytotoxic drug-induced emesis. Pancopride was studied in clinical trials in patients treated with highly emetogenic chemotherapy. It was found a combination of Pancopride with dexamethasone was the most effective against chemotherapy-induced vomiting. However, information about the further development of this drug is not available.

Mazipredone is a glucocorticoid exerting anti-inflammatory, anti-allergic and anti-shock properties.

Metamelfalan is an antineoplastic agent. Metamelfalan is the meta form of the levo isomer melphalan. Metamelfalan causes crosslinking of DNA, thereby preventing DNA replication and eventually cellular proliferation.

Olradipine (also known as S 11568) is a L-type Ca(2+) channel antagonist. This drug was being developed in France for the treatment of heart failure, hypertension, and ischemic heart disorder. However, all these studies were discontinued.

Pardoprunox is a partial D2/3 dopamine receptor agonist and full 5-HT1A serotonin receptor agonist. Partial D(2/3) dopamine (DA) receptor agonists provide a novel approach to the treatment of the motor symptoms of Parkinson's disease that may avoid common dopaminergic side effects, including dyskinesia and psychosis. Pardoprunox passed phase III clinical trial for the treatment of Parkinson's disease.

Febuverine is a spasmolytic and local anesthetic.
