Sobetirome (3,5-dimethyl-4[(4'-hydroxy-3'-isopropylbenzyl)-phenoxy] acetic acid, also known as GC-1 and QRX-431, is a member of a class of compounds known as selective thyromimetics. It was firstly developed by Thomas Scanlan’s group at the University of California-San Francisco (UCSF) in 1995. Sobetirome binds selectively to the main hepatic form of thyroid hormone (TH) receptor, TRβ1, compared to TRα1, which is principally responsible for thyrotoxic effects on heart, muscle and bone. Sobetirome also preferentially accumulates in liver. It was originally envisaged that sobetirome could be used to stimulate hepatic pathways that lower cholesterol without harmful side effects and might be used in conjunction with statins. Indeed, sobetirome progressed through preclinical animal studies and Phase I human clinical trials with excellent results and without obvious harmful side effects. Sobetirome had been in phase I clinical trials for the treatment of lipid metabolism disorders and obesity. However, this research has been discontinued.

Oxepinac was developed as an anti-inflammatory drug. Results of clinical trials have revealed that oxepinac was an effective and well-tolerated drug in the treatment of painful osteoarthritis. Experiments on animal have shown that oxepinac had no teratogenic effect on fetuses in mice and rabbits. Information about the current use of this drug is not available.

Trethocanic acid is a beta-hydroxy acid. It exerts a similar effect on the skin as salicylic acid. Trethocanic acid was used as antihypercholesterolaemic agent.

Aleglitazar is a dual agonist of PPARalpha/PPARgamma which was developed by Hoffmann-La Roche for the treatment of type 2 diabetes. Aleglitazar activates PPAR receptors with EC50 in nanomolar range and exerts a cardioprotective effect in vitro. The drug is currently in phase III of clinical trials.

Fenclorac is a potent nonsteroidal anti-inflammatory agent with significant analgesic and antipyretic activity. It inhibits prostaglandin synthesis both in vitro and in vivo.

Vebufloxacin (OPC-7241) is a nalidixic acid analog. It exhibited potent antibacterial activity against gram-positive and -negative bacteria, including Staphylococcus aureus and Pseudomonas aeruginosa.

Procymate is a cyclohexylpropyl derivative patented by Compagnie Francaise des Matieres Colorantes as a non-hypnogenic depressor of the nervous system.

Lysergide (LSD) is a semi-synthetic hallucinogen and is one of the most potent drugs known. Recreational use became popular between the 1960s to 1980s, but is now less common. LSD was first synthesized by Albert Hoffman while working for Sandoz Laboratories in Basel in 1938. Some years later, during a re-evaluation of the compound, he accidentally ingested a small amount and described the first ‘trip’. During the 1950s and 1960s, Sandoz evaluated the drug for therapeutic purposes and marketed it under the name Delysid®. It was used for research into the chemical origins of mental illness. Recreational use started in the 1960s and is associated with the ‘psychedelic period’. LSD possesses a complex pharmacological profile that includes direct activation of serotonin, dopamine and norepinephrine receptors. In addition, one of its chief sites of action is that of compound-specific (“allosteric”) alterations in secondary messengers associated with 5HT2A and 5HT2C receptor activation and changes in gene expression. The hallucinogenic effects of LSD are likely due to agonism at 5HT2A and 5HT2C receptors. LSD is also an agonist at the majority of known serotonin receptors, including 5HT1A, 5HT1B, 5HT1D, 5HT5A, 5HT6 and 5HT7 receptors. During the 1960s, LSD was investigated for a variety of psychiatric indications, including the following: as an aid in treatment of schizophrenia; as a means of creating a "model psychosis"; as a direct antidepressant; and as an adjunct to psychotherapy. LSD is listed in Schedule I of the United Nations 1971 Convention on Psychotropic Substances.

Nocodazole is an anti-mitotic drug that has long been used as an experimental tool in cell biology. Nocodazole is known to bind with high affinity to tubulin and to inhibit microtubule assembly. The tubulin molecule is a α/β heterodimer; both α and β exist as various isotypes whose distribution and drug-binding properties are significantly different. Nocodazole has the highest affinity for αβIV and the lowest affinity for αβIII. In addition, nocodazole was investigated as an anticancer drug on xenografts model and it was revealed, that nocodazole possessed a high-affinity for the cancer-related kinases ABL, c-KIT, BRAF, and MEK, and inhibited Abl, Abl(E255K) and Abl(T315I).

Brobactam is a synthetic inhibitor of beta-lactamases produced by both gram-positive and gram-negative bacteria. Brobactam potentiates the antibacterial activity of ampicillin against a wide range of clinically important bacterial strains which produce beta-lactamase. No resistant sub-population was observed amongst the strain s of staphylococci studied, and the development of resistance in vitro was not recorded in individual strains of Staphylococcus aureus and Escherichia coli exposed to subinhibitory concentrations of ampicillin/brobactam. Reduced sensitivity was observed in the case of one strain of M. morganii, which was known to produce an inducible chromosomal cephalosporinase.
