Lanicemine is a low-trapping NMDA channel blocker, which was developed by Fisons Pharmaceuticals and later by AstraZeneca for the treatment of the major depressive disorder. The development was terminated in phase II as the drug did not meet the primary endpoint.

ITROCINONIDE is a synthetic corticosteroid which showed no signs of systemic activity (cortisol depression).

ilofungin is a narrow spectrum antimycotic patented by a pharmaceutical company Eli Lilly and Co in 1981. Cilofungin is particularly active against the opportunistic fungal pathogen Candida albicans. Cilofungin action is exerted through inhibition of the synthesis of (1,3)-beta-glucan, an essential cell wall component, it invades a fungus' ability to synthesize cell walls.

ISOPREDNIDENE is a synthetic glucocorticoid. It suppresses both the release and the synthesis of adrenocorticotropin by the pituitary gland.

Pleuromulin (pleuromulitin) is a natural antibiotic isolated from Basidiomycete Pleurotus. Pleuromulitin exhibits activity mainly against gram-positive bacteria including S. aureus, Klebasiella pneumoniae and Bacillus Subtilis. Pleuromulin is an organic compound which is not reported to be used in as a drug however its derivatives have been used in treatment of infections. The first pleuromulitin that was approved in 1979 for use in veterinary medicine was semi-synthetic derivative tiamulin. Semisynthetic pleuromutilin retapamulin (ALTABAX, GlaxoSmithKline) was the first approved for topical use in humans in 2007. Another derivative of pleuromulin, Lefamulin has been successfully tested in phase 1 clinical trial for systemic use in patients (Nabriva Therapeutics AG).

Diamfenetide (aka diamphenethide) is a fasiolicide used in sheep. It is effective against immature flukes but with diminishing activity as the fluke ages. It has proven an effective compound for use in prophylactic programs against Fasciola hepatica. Diamphenethide is deacetylated in the host liver to an active monoamine and diamine. The amine of diamfenetide has an action which produces an elevation of malate concentration in Fasciola. Malate is an intermediary product of glucose in this parasite. It is known that dopamine, a putative neurotransmitter in Fasciola has a protective effect against diamfenetide but the mode of action of a diamfenetide has yet to be defined in greater detail.

Enestebol is an anabolic steroid.

Metribolone, also known as methyltrienolone, an anabolic agent, binds to the androgen receptor and was studied for the treatment of advanced breast cancer. However, because of the liver toxicity, further development of this drug was discontinued. Now, this compound is used for research purpose as synthetic androgen.
