Esculamine is a hemostatic, vasodilator and anti-inflammatory agent.

Tarenflurbil (Flurizan or R-flurbiprofen) is the single enantiomer of the racemate NSAID flurbiprofen. Tarenflurbil is a first in class, selective amyloid-beta42 (A42) lowering agent (SALA), which acts by modulating the activity of gamma-secretase, an enzyme that converts amyloid precursor protein to amyloid-beta. The reduction of A42 may prevent the development of the amyloid plaques thought to be a key pathological process associated with Alzheimer’s disease. For several years, research and trials for the drug were conducted by Myriad Genetics, to investigate its potential as a treatment for Alzheimer's disease. In a brief statement issued June 30, Myriad Genetics reports that tarenflurbil (Flurizan) failed to have a significant effect in a phase 3 trial of patients with mild Alzheimer's disease (AD). The failure of Flurizan™ is generally attributed to its insufficient pharmacodynamics, i.e., inadequate ability to penetrate the brain and engage its target protein at doses sufficient to yield an effect. Two additional Phase 3 trials were terminated and further development of Flurizan™ was discontinued. Separate clinical development of Flurizan™ for prostate cancer has also been discontinued following negative Phase 2 results. Tarenflurbil activates c-Jun N terminal kinase, increases AP-1 binding to DNA, and downregulates cyclin D1 expression, resulting in the arrest of tumour cells in the G1 phase of the cell cycle and apoptosis. This agent also affects the expression of nuclear factor kappa B, a rapid response transcription factor that stimulates the immune response to tumour cells. Tarenflurbil does not inhibit the enzyme cyclooxygenase. The Fraunhofer Institute for Molecular Biology and Applied Ecology is currently developing tarenflurbil for the treatment of relapsing, remitting multiple sclerosis.

Ethoxazene (2,4-diamino-4-ethoxyazobenzene) is an analgesic compound. It may be used as an indicator of acidity in an examination of gastric function.

Fenamifuril is an antiinflammatory and antirheumatic agent.

Naproxol is an aromatic ether in which the substituents on oxygen are 6-[(2S)-1-hydroxypropan-2-yl]-2-naphthyl and methyl. It has a role as a non-steroidal anti-inflammatory drug, a non-narcotic analgesic and an antipyretic.

Raxofelast (IRFI 016) is a hydrophilic vitamin E-like antioxidant, that was developed to maximize the antioxidant potency of phenols related to vitamin E. It has been investigated as a mucoactive drug, a type of drug that is used for treatment of respiratory diseases. Also, in diabetic mice, raxofelast was shown to improve wound healing to a level close to that seen in healthy mice, and in another study it improved clinical outcomes in experimental burn wounds. In a rat model of myocardial damage, raxofelast was found to be a useful drug to reduce heart attacks. This compound has good bioavailability and physicochemical properties. No clinical trials have been conducted.

Clamidoxic acid is a derivative of phenoxyacetic acid developed in the late 1950s by Smith and Nephew Research Ltd. Clamidoxic acid has been shown to have anti-inflammatory activity and low toxicity in animal tests. The compound was investigated in the clinical trials in patients suffering from rheumatoid arthritis and painful uncomplicated osteoarthritis of the hip, however, no further clinical development was reported.

Salethamide was developed as an anti-inflammatory agent to use as an analgesic. However, information about the further study of this compound is not available.

Bimosiamose, discovered by Encysive Pharmaceutical and presently being developed by Revotar Biopharmaceuticals, is an 863 g/mol molecular weight dimer with minimal carbohydrate content and is, to date, the leading selectin inhibitor in clinical development. It was developed as anti-inflammatory drug fir the treatment of acute chronic inflammatory disorders including COPD. This compound has shown promise in a phase IIa 'proof of concept' trial in patients with asthma, reducing airway recruitment of eosinophils after intravenous administration. In acute lung injury, neutrophils (a type of white blood cells, thus belonging to the group of cells of the body’s defence system-the immune system) are drawn to the small lung bloodvessels and migrate into the air sacs (alveoli). There they release substances, which cause the inflammation leading to further destruction of the lung tissue. Bimosiamose disodium is expected to hinder the migration of these neutrophils into the alveoli.

Ciproquazone (SL-573) is a non-steroidal anti-inflammatory drug, a derivative of quinazolinone, discovered by Sumimoto Chemical Co. in the late 1970s. Ciproquazone acts as a reversible inhibitor of prostaglandin synthetase. In animal models, ciproquazone demonstrated antipyretic, analgesic and anti-inflammatory activity. The drug was evaluated in a clinical in acute purulent diseases in the field of orodental surgery.
