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.

Codoxime is a synthetic derivative of an opiate dihydrocodeinone. It differs from dihydrocodeinone by the substitution of a carboxymethyl oxime for the ketonic oxygen at carbon 6 of the dihydrocodeinone molecule. Codoxime has been proposed as an antitussive with prolonged duration of action. In a clinical trial conducted on prisoner volunteers in 1966, it was found that codoxime has a capacity to produce physical dependence of the morphine type.

Palifosfamide or ZIO-201 (isophosphoramide mustard; IPM), a bi-functional DNA alkylator, is the active metabolite of ifosfamide (IFOS). IFOS and the related drug cyclophosphamide (CPA) are widely used anti-cancer drugs. Both are pro-drugs and need to be metabolized to be active. Their clinical use is limited by the toxicity associated with some of their metabolites. Palifosfamide has shown efficacy in diverse cancer models. ZIOPHARM Oncology Inc, under license from Dekk-Tec Inc, was developing palifosfamide, a formulation of isophosphoramide mustard with tris(hydroxymethyl)aminomethane salt-stabilization (palifosfamide-tris) and previously with lysine-stabilization (palifosfamide-lys). Preclinical studies and phase I and I/II clinical trials demonstrated that palifosfamide-tris had an antitumor efficiency comparable or superior to that of ifosfamide. To date ZIO-201 is not present in ZIOPHARM pipeline.

Encyprate (MO-1255) is a unique drug in being inactive as an MAO inhibitor in vitro but very active in vivo. It most probably is converted by the body to ethyl-N-benzyl-N-cyclopropylcarbamate which is an active MAOI in vitro. I was studying in the treatment of depression.

Hoquizil, a phosphodiesterase inhibitor, was used as a bronchodilator agent. Information about the current use of this drug is not available.

Ibiglustat (GZ/SAR402671 or Genz-682452) is a small molecule inhibitor of glucosylceramide synthase. Ibiglustat has been demonstrated to effectively lower glycosphingolipid synthesis. Genzyme, a Sanofi Company is developing Ibiglustat for the treatment of Parkinson's Disease, Gaucher Disease, and Fabry Disease.

Securinine is a plant-derived alkaloid from the Securinega plant that has been used clinically as a therapeutic for primarily neurological related diseases. Securinine is well-known GABAA antagonist and recently it was found that Securinine is able to up-regulate p53 protein and to modulate the related family member p73 protein in a p53-dependent fashion, inducing p73 in the HCT116 p53(-) cells and down-regulating it in the p53(+) cells. Securinine induces G1 phase cell cycle arrest, upregulates expression of p53 and Bax, and downregulates expression of Bcl-2, PI3K, mTOR, and p70s6k in breast cancer cells and promyelocytic leukemia cells. Securinine activates p38 MAPK, enhancing monocyte antibacterial activity in vitro as well. This compound also exhibits antimicrobial activity against Alternaria, Curvularia, and Helminthosporum. Additionally, securinine decreases AChE activity and suppresses amyloid-β (Aβ)-induced glial inflammatory responses in animal models of Alzheimer’s disease, improving cognitive deficits. Securinine’s activity as a GABA antagonist, likely explains its reported clinical success in limited studies for the treatment of neurological conditions such as amyotrophic lateral sclerosis (ALS), poliomyelitis and multiple sclerosis. Securinine has not been utilized in the United States, it has been used clinically in several other countries particularly China and Russia. In China, it is considered one of the 50 fundamental Chinese herbs and is used in Chinese herbal medicine.
