Watanidipine (AE0047) had been NDA filed for the treatment of hypertension in Japan. Watanidipine (as Calbren®) was awaiting registration with Mitsubishi Pharma Corporation in Japan. However, Mitsubishi Pharma Corporation has discontinued the development of this drug. Watanidipine had also been in phase II clinical trials for the treatment of stroke and preclinical trials for atherosclerosis. However, no recent development has been reported. Watanidipine (AE0047) has being shown to be a calcium antagonist with protective effects against cerebral ischaemia and the occurrence of stroke in several animal models.

Phenibut (beta-phenyl-gamma-aminobutyric acid or 4-amino-3-phenylbutyric acid) is a neuropsychotropic drug that was discovered and introduced into clinical practice in Russia in the 1960s. It has anxiolytic and nootropic (cognition enhancing) effects. It acts as a GABA-mimetic, primarily at GABA(B) receptors. Pharmacological activity of racemic phenibut relies on R-phenibut and this correlates to the binding affinity of enantiomers of phenibut to the GABAB receptor. In addition R-phenibut binds to the α2-δ subunit of voltage-dependent calcium channels. It is highly effective in treating anxiety, post-traumatic stress disorder, depression, asthenia, insomnia, alcoholism, stuttering, and vestibular disorders. It also improves mental performance (attention, memory, speed and accuracy of sensory-motor reactions), physical performance, reduces sleep disorders as well as movement and speech disorders.

Hexoprenaline is a selective beta2-adrenoreceptor agonist indicated for use in the treatment of bronchospasm associated with obstructive airways diseases, including asthma, bronchitis and emphysema. In many countries the drug is used as tocolytic agent (under the trade name gynipral).

Enilconazole is a synthetic broad-spectrum antimycotic with a high activity against most of the common dermatophytes and various other fungi and yeasts. It is a selective inhibitor of ergosterol biosynthesis, an essential component of the cell membrane of fungi and yeasts. This results in irreversible changes which are the origin of the fungicidal effect. Enilconazole is marketed under the brand name Imaverol among others. Imaverol concentrated solution is a synthetic antimycotic with a potent antifungal action against dermatophytes such as: Trichophyton verrucosum, Trichophyton mentagrophytes, Trichophyton equinum, and Microsporum canis in horses and dogs.

Methaniazide (metaniazide) is the methanesulfonate derivative of isoniazid with antibacterial properties. It is used used primarily as a tuberculostatic. It remains the treatment of choice for tuberculosis.

Isoniazid glucuronate is a less toxic derivative the antibacterial drug isoniazid. Isoniazid is recommended for all forms of tuberculosis in which organisms are susceptible. Isoniazid itself is a prodrug and must be activated by bacterial catalase. Isoniazid inhibits InhA, the enoyl reductase from Mycobacterium tuberculosis, by forming a covalent adduct with the NAD cofactor.

Sucrosofate (sucrose octasulfate) is a class of organic compounds known as disaccharide sulfates carrying one or more sulfate group on a sugar unit. It is used to encapsulate some anticancer drugs in liposomes allowing for highly active formulations against solid tumors and immunotargeting to cancer-overexpressing cell surface receptors. ONIVYDE (liposomal irinotecan) for intravenous use encapsulates an aqueous space containing irinotecan in a gelated or precipitated state as the sucrose octasulfate salt was initially approved by FDA in 1996 for treatment of pancreatic cancer. Sucrose octasulfate (SOS), a chemical analogue of heparin, has been demonstrated to activate fibroblast growth factors signalling pathways and SOS-mediated dimerization of FGF1 was observed. SOS can suppress thrombin generation in plasma that suggests a potential for oversulfated disaccharides in controlling heparin cofactor II -regulated thrombin generation.

Ethybenzatropine (Ponalid) is an anticholinergic and antihistaminergic drug. It was used as an antiparkinsonian agent. A significant increase in the duration of action of levodopa-induced improvement in parkinsonian symptoms was observed following the administration of ethybenzatropine. Ethybenzatropine also improved, or tended to improve the duration and seventy of onset and end-of-dose levodopa-induced dyskinesias. Thus when levodopa is administered together with etybenzatropine, its length of action on parkinsonian symptoms is prolonged.

Mitoguazone is a guanylhydrazone derivative with potential antineoplastic activity. Mitoguazone inhibits S-adenosyl-L-methionine decarboxylase (SAMD), an enzyme involved in the synthesis of polyamines, resulting in a decreased proliferation of tumor cells, antimitochondrial effects, and p53-independent apoptosis. In the 1960s the drug was investigated in clinical trials. Despite the responses in acute leukemia, chronic myelogenous leukemia, lymphoma, multiple myeloma, head and neck cancer, esophageal cancer and other types of cancer, the development of the drug was discontinued because of marked myelosuppression and mucositis. Using a weekly schedule of administration, mitoguazone had minimal toxicity and showed limited activity in patients with lymphoma, esophageal cancer, prostate cancer, and other types of tumors.
