Encyprate (MO-1255) is a unique drug in being inactive as an MAO inhibitor in vitro but very active in vivo. It most probably is converted by the body to ethyl-N-benzyl-N-cyclopropylcarbamate which is an active MAOI in vitro. I was studying in the treatment of depression.

Tasuldine is as an orally active bronchosecretolytic agent that was clinically effective in human. However, information about the further development and use of this drug is not available.

Pelitrexol (also known as AG2037) was developed by Pfizer as a glycinamide ribonucleotide formyltransferase inhibitor. This drug was studied in phase II clinical trials in patients with metastatic non-small cell lung cancer and in patients with metastatic colorectal cancer who failed treatment. In addition, the drug participated in a phase I clinical trial in treating patients who have advanced, metastatic, or recurrent solid tumors. Information about the further development of pelitrexol is not available.

Nonaperone, a butyrophenone, is a neuroleptic agent. It is antipsychotic in schizophrenics at doses which do not elicit extrapyridal side effects.

Alazanine triclofenate is a mixture of one molecule of 3-ethyl-2-(3-(3-ethyl-2-benzothiazolinylidene)propenyl)benzothiazolium 2,4,5-trichlorophenate and two molecules of 2,4,5-trichlorophenol. It is an antiparasitic agent. It is antimalarial drug, highly active against multiple Plasmodium falciparum isolates with IC50 value of 2.36E-07 M.

Nuclomedone (TEI-3096), a thiazolopyrimidine compound has been shown to suppress adjuvant arthritis in rats without any effect on conventional inflammation. TEI-3096 also enhanced the delayed type hypersensitivity in mice and rats. These results suggests that TEI-3096 restores the abnormal immune response. Nuclomedone was discovered by Teijin and investigated as a potential treatment for rheumatoid arthritis and inflammatory disorders.

L-Arabinose is a monosaccharide extracted from plant gums, corn fiber and beet pulps. It is a poorly-absorbed, readily-available sweet-tasting pentose. L-Arabinose is known to suppress obesity by regulating the fasting blood glucose level and the insulin resistance index. L-arabinose is a non-caloric sugar. L-arabinose may inhibit intestinal sucrase activity and thereby delay sucrose digestion.
