A naturally occurring serine derivative diazo compound with antineoplastic properties, Azaserine functions as a purine antagonist and glutamine analogue (glutamine amidotransferase inhibitor) that competitively inhibits pathways in which glutamine is metabolized. An antibiotic and antitumor agent, Azaserine was used in clinical studies as a potential antineoplastic agent. Azaserine is an inhibitor of glutamine: fructose-6-phosphate amidotransferase (GFAT), which is the rate-limiting enzyme in the hexosamine biosynthetic pathway. Azaserine is used to model pancreatic cancer in rodents.
Dichlorvos is a synthetic organic chemical used as an insecticide. Dichlorvos does not occur naturally in the environment, but is manufactured by industry. Dichlorvos is sold under many trade names including Vapona®, Atgard®, Nuvan®, and Task®. It is also used as an insecticide for slow release on pest-strips for pest control in homes.  Dichlorvos is used as an anthelmintic (worming agent) for dogs, swine, and horses, as a botacide (agent that kills fly larvae) for horses, and in flea collars for dogs. In 1995, EPA proposed cancellation of dichlorvos for all home uses, and for many commercial and industrial uses.

Favipiravir (originally known as T-705) is an orally administered novel anti-viral compound with a unique mechanism of action that is active against a wide range of RNA-based viruses in laboratory tests. Favipiravir has recently being approved in Japan under the brand name Avigan. Avigan is an experimental antiviral drug being developed by Toyama Chemical of Japan. It is a viral RNA polymerase inhibitor with a new mechanism of action, inhibiting viral gene replication within infected cells to prevent the propagation. Favipiravir is phosphoribosylated by cellular enzymes to its active form, favipiravir-ribofuranosyl-5′- triphosphate (RTP). Favipiravir is active against a broad range of influenza viruses, including A(H1N1)pdm09, A(H5N1) and the recently emerged A(H7N9) avian virus. It also inhibits influenza strains resistant to current antiviral drugs, and shows a synergistic effect in combination with oseltamivir, thereby expanding influenza treatment options. A Phase III clinical evaluation of favipiravir for influenza therapy has been completed in Japan and two Phase II studies have been completed in the United States. In addition to its anti-influenza activity, favipiravir blocks the replication of many other RNA viruses, including arenaviruses (Junin, Machupo and Pichinde); phleboviruses (Rift Valley fever, sandfly fever and Punta Toro); hantaviruses (Maporal, Dobrava, and Prospect Hill); flaviviruses (yellow fever and West Nile); enteroviruses (polio- and rhinoviruses); an alphavirus, Western equine encephalitis virus; a paramyxovirus, respiratory syncytial virus; and noroviruses.

TAT-59 (Miproxifene Phosphate) is a triphenylethylene analog of tamoxifen. TAT-59 is the phosphate ester prodrug of the practically insoluble parent drug DP-TAT-59. It is an antiestrogen developed in Japan for breast cancer. It is a potent antitumor agent for hormone-dependent tumors. Most of TAT-59 metabolites possessed remarkable binding affinity toward estrogenic receptors as well as fairly good antiuterotrophic activity.

Rilmenidine (brand names Albarel, Hyperium, Iterium and Tenaxum) is an imidazoline derivative used for the treatment of hypertension. Rilmenidine, an oxazoline compound with antihypertensive properties, acts on both medullary and peripheral vasomotor structures. Rilmenidine shows greater selectivity for imidazoline receptors than for cerebral alpha2-adrenergic receptors, distinguishing it from reference alpha2-agonists. Rilmenidine is as effective in monotherapy as all other first line classes of drugs, including diuretics, beta-blockers, angiotensin converting enzyme (ACE) inhibitors, and calcium antagonists. It is well tolerated and can be taken in combination for greater efficacy. Sedation and dry mouth are not prominent side effects and withdrawal hypertension is not seen when treatment is stopped abruptly. In addition to a reduction in blood pressure, Rilmenidine has been shown to improve glucose tolerance, lipid risk factors, and insulin sensitivity.

Aminopropyl racementhyl phosphate is a prodrug of menthol patented by Pacific Corporation (Korea). Upon administration, it is enzymatically decomposed into menthol and 3-aminopropylphosphoric acid, a component used for anti-aging cosmetic composition. Aminopropyl racementhyl phosphate was found to reduce the irritation of menthol while maintaining its useful effects.

Cytarabine ocfosfate (commercial name: Starasid) is a prodrug having stearyl group attached to phosphoric acid at 5' position of arabinose moiety of cytosine arabinoside (Ara-C). This drug is given orally. The mode of action is in the inhibition of DNA synthesis after conversion to Ara-CTP as in Ara-C. The drug is metabolized in the liver, producing the intermediate metabolite, C-C3PCA which is converted to Ara-C gradually. This property results in the maintenance of relatively long time the blood Ara-C levels. This was proved to be active clinically against acute leukemia and MDS.
