Ofornine is a vasodilator with antihypertensive activity. Experiments on rats have shown that ofornine reduced spontaneously hypertensive (SH) blood pressure through vasodilating and presynaptic adrenolytic activities, and that a dopaminergic mechanism may be involved. Information about the current use of this drug is not available.

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.

Oxarbazole was developed as an antiasthmatic agent that inhibited the only bronchoconstriction induced by immune complexes. This drug has never been marketed.

Edatrexate (10-ethyl-10-deazaaminopterin or 10-EDAM) is an analog of methotrexate with improved pre-clinical antitumor activity, more selective cellular uptake, and with the more extensive formation of intracellular polyglutamate metabolites. This drug is a new dihydrofolate reductase inhibitor, which was studied in phase II clinical trial for the patients with different cancers. The studies were discontinued, for example, in advanced renal cell carcinoma edatrexate in the investigated dose and schedule had minimal activity and was toxic. In case of non-small-cell lung cancer, the dosing schedule of edatrexate did not appear to be improved compared to other chemotherapeutic regimens. In addition, edatrexate was involved in the experiment for the treatemnt of rheumatoid arthritis, but this study was also discontinued.
