Miroprofen, an imidazopyridine derivative, possesses anti-inflammatory properties. It was shown that this compound could be effective in suppressing pain responses and acute inflammation accompanied by increased vascular permeability. Analgesic effect of this compound was studied in post-extraction pain. However, information about the current study of this agent is not available.

Dicloralurea is a herbicide and veterinary food additive that inhibits methane production in herbicide ruminants. It acts as a growth stimulant and now superseded.

Norleucine (L-norleucine) is a 2-aminohexanoic acid is an alpha-amino acid that is caproic acid substituted by an amino group at position 2. It derives from a hexanoic acid. It is used experimentally to study protein structure and function. Norleucine appears to inhibit bacterial growth due to incorporation into proteins in place of methionine, as the analogue inhibits methionine incorporation but does not significantly reduce its synthesis. L-norleucine had antiviral activity in thermophile. In vitro and in vivo assays revealed that L-norleucine significantly suppressed metastasis of gastric and breast cancer cells. L-norleucine interacted with hnRNPA2/B1 protein to inhibit the expressions of Twist1 and Snail, two inhibitors of E-cadherin, and promote the E-cadherin expression, leading to the inhibition of tumor metastasis.

Inicarone is benzofuryl derivative with potent antifibrinolytic activity.

GTS-21 (also known as DMBX-A), a selective alpha-7 nicotinic acetylcholine receptor agonist that has demonstrated memory and cognition enhancement activity in human clinical trials. GTS-21 has been studied in Phase II in patients with schizophrenia and in patients with Alzheimer disease. However, these studies were discontinued. GTS-21 was also involved in phase II to reduce negative affect, improve cognition and/or reduce smoking relapse in healthy adult men and women who are chronic cigarette smokers. However, this study was withdrawn. Besides, GTS-21 has participated in phase II to investigate safety and efficacy in adults with attention-deficit hyperactivity disorder.

Esorubicin (4'-deoxydoxorubicin, NSC 267469) is a synthetic derivative of the anthracycline antineoplastic antibiotic doxorubicin with potential antineoplastic activity. Esorubicin intercalates into DNA and inhibits topoisomerase II, thereby inhibiting DNA replication and ultimately, interfering with RNA and protein synthesis. This agent exhibits less cardiotoxicity than the parent antibiotic doxorubicin, but may cause more severe myelosupression compared to other compounds within the anthracycline class. Esorubicin was being clinically tested for the treatment of solid tumors as well as lymphomas an leukemias. Esorubicin development has been discontinued.

Bepafant (also known as WEB-2170), an inverse agonist of platelet-activating factor receptor that has been preclinical studied in asthma, Ischemic heart disorder and in reperfusion injury after orthotopic liver transplantation. However, these studies were discontinued. Besides, several experiments have shown that bepafant induced apoptosis in human acute myelogenous leukemia and thus could be the powerful antileukemic agent.

Tinisulpride is a sulfamoylbenzoic acid patented by Fabre, Pierre, S. A. as an antiemetic agent.

Camphramine is biologically active salt of N-methylcoramine and 2-oxo-3-Bornanesulfonic acid. N-methylcoramine is a potent stimulant of gastrin release present in alcoholic beverages produced by alcoholic fermentation, but not by distillation.

Butinoline (also known as azulone) was used as an antispasmodic drug to treat gastritis.
