Gadocoletic acid (also Gadoletic acid trisodium salt, or B22956/1) is a magnetic resonance contrast agent. Based on results from animal imaging experiments and pharmacokinetic data it was suggested that gadocoletic acid trisodium salt has strong potential for clinical use in Magnetic Resonance Coronary Angiography and Myocardial Perfusion Imaging. The small molecules of gadocoletic acid are bound after injection to large human serum albumin molecules in coronary vessels with the result of high vessel/muscle contrast. The ability of B229563− (anion) to bind to more than one site on the albumin molecule allows a positive correlation between dose and blood relaxation rate enhancement at doses higher than 0.05 mmol/kg, the dose that produces roughly a total plasma concentration equimolar to the albumin concentration at equilibrium distribution. Gadocoletic acid is thought to be highly efficacious in inversion recovery-prepared 3D gradient-recalled echo, navigator echo-gated coronary angiography in humans already at doses below 0.1 mmol/kg.

Cevipabulin is a synthetic, water-soluble tubulin-binding agent with potential antineoplastic activity. Cevipabulin appears to bind at the vinca-binding site on tubulin but seems to act more similar to taxane-site binding agents in that it enhances tubulin polymerization and does not induce tubulin depolymerization. The disruption in microtubule dynamics may eventually inhibit cell division and reduce cellular growth.

Febuverine is a spasmolytic and local anesthetic.

Patamostat (E-3123) is a protease inhibitor in vivo and in vitro. Inhibitory activity was shown toward trypsin, thrombin, plasmin, cathepsin-B and kallikrein. Patamostat is effective toward experimental pancreatitis and disseminated intravascular coagulation (animal models).

Temiverine was developed as an antimuscarinic and calcium-antagonist agent for the treatment of overactive bladder. Temiverine participated in clinical trials; however, the development of the drug was discontinued on the pre-registration stage.

Tifurac is a benzofuranacetic acid derivative patented by Syntex, Inc. as an analgesic, anti-inflammatory, and antipyretic agent. In preclinical models, Tifurac can exert anti-inflammatory and analgesic activity in rat paw edema assay and mouse writhing assay.

Atropine-N-oxide hydrochloride is an alkaloid of the belladonna plants. It is the major metabolite of atropine. It is a competitive nonselective antagonist at central and peripheral muscarinic acetylcholine receptors.

Heidelberg Pharma Research developed fosalvudine tidoxil, a prodrug derived from the nucleoside reverse transcriptase inhibitor alovudine, for the treatment of HIV infections. This drug had reached phase II clinical trials before its development was discontinued.
