Iomorinic Acid is triiodobenzamide derivative patented by Lentia G.m.b.H. as a radiographic contrast medium for liver imaging.

Octazamide an analgesic that was studied as an anti-inflammatory agent. Information about the current development of this compound is not available.

Melizame is a sugar substitute for sweetening caloric or noncaloric materials.

Cinperene is an investigational compound proposed for clinical use as a strong and long-acting peripheral central anticholinergic. In animal models, cinperene inhibited mydriasis, pilocarpine-induced salivation, and lacrimation, scratching, hunching and other symptoms.

Spirotriazine is a dihydrotriazine derivative patented by Burroughs Wellcome & Co. (U.S.A.) Inc. as the anthelmintic agent. In preclinical models, Spirotriazine shows potent activity against intestinal parasites and negligible microbiological activity.

Efipladib is an inhibitor of cytosolic phospholipase A2 alpha both in vitro and in vivo. It is able to relieve inflammatory pain in animal model. Additionally, efipladib exerts antitumor potential. Efipladib was in clinical trials for the treatment of asthma and arthritis however its development has been discontinued.

Evobrutinib is a highly selective, irreversible inhibitor of Bruton's tyrosine kinase (BTK). It potently inhibits BCR- and Fc receptor-mediated signaling and, thus, subsequent activation and function of B cells and innate immune cells such as monocytes and basophils. Evobrutinib demonstrated effectivity in autoimmune disease preclinical models. Evobrutinib is being developed by Merck Serono for the treatment of various autoimmune disorders.

Namitecan (ST1968) is a camptothecin analogue being developed by sigma-tau (a subsidiary of Alfasigma) in Switzerland for the treatment of cancer. Namitecan, a novel hydrophilic camptothecin analog of the 7-oxyiminomethyl series, was selected for clinical development on the basis of its promising preclinical efficacy. Namitecan is a topoisomerase I inhibitor. Namitecan exhibited an acceptable toxicity profile, with neutropenia being the dose-limiting toxic effect, and clinical benefit was appreciable in patients with different tumor types, particularly bladder and endometrium carcinomas.

Oxamisole (previously known as PR 879-317A), a selective immunomodulatory agent that was studied for the treatment of viral infections. Experiments on mice have shown that antiviral properties of oxamisole were mediated through the immunomodulatory effects of this compound on the immune system. However, further development of this drug was discontinued.

Zaurategrast (CDP323) is an ethyl ester prodrug of CT7758, a potent carboxylic acid antagonist of integrin alpha4-beta1 (α4β1) or very late antigen 4 (VLA4). CDP323 was under development with UCB and Biogen Idec for the treatment of multiple sclerosis. Its development was discontinued in 2009 based on inadequate interim efficacy data in a phase II clinical trial.
