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

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.

Flutiazin was studied as an anti-inflammatory agent to use in veterinary. Information about the current use of this agent is not available.

Talaglumetad (also known as LY-544344) is a bicyclohexane derivative patented by Eli Lilly and Company as modulators of metabotropic glutamate receptor. Talaglumetad acts as a prodrug of Eglumegad, a selective agonist of metabotropic glutamate receptors (mGluR2/3) and metabolized to release active compound by both human jejunal homogenates and rat liver homogenates. In experiments on mice, Talaglumetad was found to be as effective as diazepam for treating anxiety symptoms in several standard tests, but without producing any of the negative side effects of diazepam such as sedation and memory impairment.

Kythera Biopharmaceuticals (a subsidiary of Allergan) is developing setipiprant, an oral prostaglandin D2 (PGD2/CRTH2) receptor antagonist, for the treatment of alopecia. Setipiprant was initially developed as a treatment for allergic rhinitis, but recent hair loss-related discoveries have made it a better candidate for hair loss reversal. As CRTH2 antagonist, setipiprant, blocks the effects of prostaglandin D2 (PGD2) role in inflammation and, in consequence, the amplification and maintenance of allergic reactions. It targets the allergic inflammation at the beginning of the cascade. In clinical trials for allergic rhinitis and asthma, the drug performed quite well in the treatment of allergen-induced airway responses in asthmatic patients. It was also well tolerated by participants. However, its results were similar to those of drugs already on the market, so further trials were discontinued. In 2012, researchers discovered a link between the PGD2 receptor and hair loss. More specifically, this receptor is seen at high levels in the scalps of men diagnosed with Androgenetic Alopecia (AGA). setipiprant steps in before PGD2 attaches to the receptors, and therefore prevents receptor activation and, as a result, hair loss. With the discovery of the possible link to PGD2 receptors, Kythera acquired the drug, and trials began to test the effects of setipiprant on hair loss.

Lemuteporfin is a newly introduced, light-sensitive drug for use in combination photodynamic therapy (PDT). It acts on mitochrondria to initiate the apoptotic cascade resulting in cell death (apoptosis). The photosensitizer was highly potent, killing cells at low nanomolar concentrations upon exposure to activating light. The cellular uptake of lemuteporfin was rapid with maximum levels reached within 20 min. Mitogen-activated lymphoid cells accumulated more of the lemuteporfin than their quiescent equivalents, supporting selectivity. Lemuteporfin had been in phase II clinical trials for the treatment of benign prostatic hypertrophy. It is in phase I clinical trials for the treatment of acne rosacea.

Picenadol is a 4-phenylpiperidine derivative and a racemic mixture whose mixed agonist-antagonist properties are a consequence of the d-isomer being a potent opiate agonist, whereas the I-isomer is an opioid antagonist. In the mouse writhing and rat tail heat tests, the analgesic potency of picenadol is estimated to be 1/3 that of morphine. Picenadol itself has weak antagonist activity, whereas the antagonist potency of the l-isomer is approx. 1/10 that of nalorphine. Picenadol has high affinity for both the mu and delta receptors but a markedly lower affinity for the kappa receptor. Extensive pharmacological investigations show picenadol to have a low potential to produce opiate-like side effects, including a low liability for abuse and physical dependence. Antinociceptive properties of picenadol arise from mu agonist actions of the dextrorotatory isomer and that the levorotatory isomer acts to limit the efficacy of the racemate.
