Isonicotinic acid considered to be inactive isomer of nicotinic acid. Isonicotinic acid is a metabolite of pyridine-4-carboxy hydrazide (isonicotinyl hydrazide; isoniazid) a front-line weapon in the battle against tuberculosis. Isonicotinic acid and its derivatives are used in manufacturing pharmaceuticals and agrochemicals.

Tazanolast, an anti-allergic and anti-asthmatic agent with selective mast-cell stabilising effects, was developed jointly by Wakamoto and Torii Pharmaceuticals.

Diamminedichlorodihydroxyplatinum IV is the platinum-based antineoplasticis agent. Oxaliplatin is cis, cis, trans- isomer of Diamminedichlorodihydroxyplatinum IV. Oxaliplatin show high stability and therefore can be utilized orally for outpatient care. Although oxoplatin is capable of binding directly to DNA after prolonged incubation, platinum(IV) agents are considered to be largely inert prodrugs that are converted to highly cytotoxic platinum(II) compounds by reducing substances, enzymes, or microenvironmental conditions. Reaction of oxoplatin with 0.1 M hydrogen chloride mimicking gastric acid yields cis-diammine-tetrachlorido-platinum(IV) (DATCP[IV]), which exhibits two-fold increased activity. The oxoplatin metabolite DATCP(IV) constitutes a potent cytotoxic derivative that may be produced by gastric acid or acidic areas prevailing in larger solid tumors, depending on the respective pharmaceutical formulation of oxoplatin.

Manganese gluconate is a manganese salt of gluconic acid. Manganese gluconate is sometimes used as a food additive for its texture and light pink coloring. As a food additive, manganese gluconate increases satiety, and the texture of processed foods related to mouth feel. However, in recent years, manganese gluconate has been used less and less as a food additive due to its high toxicity. Many food manufacturers have abandoned using manganese gluconate in favor of other chemical compounds that provide similar effects with a lower toxicity. According to the Food and Drug Administration, manganese gluconate is generally recognized as safe, or GRAS. However, high amounts of manganese gluconate intake, upwards of 15 mg per day, may cause potentially serious health risks. Manganese gluconate toxicity may cause a chemical imbalance in the brain, increasing your risk of developing anxiety, depression, nervousness, psychosis, and mania. Manganese gluconate is used for prevention of deficiency and osteoporosis (off-label).

Mebhydrolin (INN) or mebhydroline is a histamine H1-receptor antagonist. It is not available in the United States, but it is available in various other countries under the brand names Bexidal and Diazolin. It is used for symptomatic relief of allergic symptoms caused by histamine release, including nasal allergies and allergic dermatosis.

Sulforidazine (Imagotan (Sandoz); Inofal (Sandoz)) is a typical piperidine-type phenothiazine antipsychotic agent. It is dopamine receptor blocker. Being the second active metabolite of thioridazine (converted from mesoridazine), Sulforidazine is significantly more potent than the parent drug.

Spasmolytic drug pramiverine was used in the active treatment of labor. In addition, it participated in clinical trials for patients with colitis syndrome. It was revealed, that pramiverine had improved the conditions of patients.

Bucloxic acid, a nonsteroidal anti-inflammatory agent, which was studied to treat the chronic glomerular nephropathy.

Chloropyramine is an antagonist of H1 histamine receptors. It is indicated for the treatment of various forms of allergic reactions. Chloropyramine is a drug capable of (1) inhibiting the biochemical function of VEGFR-3 and FAK, (2) inhibiting proliferation of a diverse set of cancer cell types in vitro, and (3) reducing tumor growth in vivo.

Fazadinium (used as a bromide salt) is a muscle relaxant, which was applied in anesthesia under the name Fazadon. The current marketing status is unknown and the drug is supposed to be discontinued.
