PF-04457845 is a fatty acid amide hydrolase 1 inhibitor developed by Pfizer for the treatment of inflammatory and noninflammatory pain disorders. The drug was tested in phase II in patients with osteoarthritis of the knee, but found to have the same effect as placebo. It was also assessed in phase II clinical trial for its effect on marijuana withdrawal and Tourette syndrome.

Gluceptate sodium also known as sodium glucoheptonate (H-Quest A300) is a non-toxic, a non-hazardous chelating agent, which forms stable complexes with di- and trivalent metal ions such as Ca2+, Fe2+, Fe3+, Al3+, etc. This substance is highly compatible with strong alkaline mediums and can prevent the bacterial degradation of the solution. Gluceptate sodium has various applications in water treatment, agricultural, cosmetics, textile processing and in some others fields.

LANOPEPDEN is an inhibitor of peptide deformylase, a bacterial enzyme required for protein maturation. It was in development for the treatment of complicated bacterial skin infection and hospitalized community-acquired pneumonia.

XG-102 (also known as brimapitide), a D-stereoisomer of a c-Jun-N-terminal kinase-1111 was developed in a biocompatible gel formulation for the treatment of sudden sensorineural hearing loss with a single-dose administration into the middle ear. It’s a cell-penetrating peptide which inhibits the JNK stress kinase. JNK is activated following various types of cochlear insults (stress) that cause acute inner ear hearing loss and plays a key role in apoptosis of sensory cells as well as in inflammatory responses. By blocking JNK, AM-111 protects stress-injured cochlear cells and helps to prevent or reduce chronic hearing loss. Auris Medical's otoprotective drug AM-111 has been granted orphan drug status by the U.S. Food and Drug Administration (FDA) for the treatment of acute sensorineural hearing loss (ASNHL), a condition which may occur following various inner ear injuries. In addition, XG-102 was studied in phase III clinical trials in the treatment of acute inner ear hearing loss and in the reduction of post-cataract surgery intraocular inflammation. Besides, XG-102 is advancing through pre-clinical development with programs in ocular inflammation, urology, nephrology and Alzheimer’s disease.

2,2-DIMETHYLBUTYRIC ACID (HQK-1001) is an orally administered SCFAD (Short Chain Fatty Acid Derivative), which has shown an excellent safety profile and biologic effects on fetal hemoglobin induction and red blood cell production in the laboratory, relevant animal models, and in clinical trials carried out in healthy human subjects as well as patients with sickle cell disease and beta thalassemia. The compound has received Orphan Drug Designation in the United States and Europe for both sickle cell disease and beta thalassemia. HemaQuest Pharmaceuticals was developing HQK-1001 for the oral treatment of sickle cell anaemia and beta thalassaemia. HQK-1001 has been evaluated in phase II trials for beta thalassaemia and sickle cell anaemia.

Epetraborole (AN3365 or GSK2251052) is a novel boron-containing antibiotic that inhibits bacterial leucyl tRNA synthetase. It is active against Gram-negative bacteria, including Enterobacteriaceae bearing NDM-1 and KPC carbapenemases, as well as P. aeruginosa. Epetraborole was under development for the treatment of Gram-negative bacterial infections.

TAK-875 (Fasiglifam) is the potent, selective and orally bioavailable GPR40 agonist. The drug was in Phase III clinical trials for the treatment of type 2 diabetes mellitus. Termination phase III development of TAK-875 for the potential treatment of type-2 diabetes mellitus was announced in 2013 due to concerns about liver safety.

Glutathione arsenoxide (GSAO) is a peptide trivalent arsenical that has potential anti-angiogenic capability, suggesting that it could be used for treatment in cancers where tumor metastasis relies on new blood vessel formation (angiogenesis). Endothelial cell proliferation drives new blood vessel formation. GSAO treatment causes a concentration-dependent increase in superoxide levels, ATP depletion, mitochondrial depolarization, and apoptosis in proliferating, but not endothelial cells. GSAO is able to block blood flow to solid tumors in mice, thereby inhibiting tumor growth in mice with no apparent toxicity at efficacious doses. Initial experiments have implicated GSAO in perturbing mitochondrial function. Other molecular effects of GSAO in human cells, for example on the phosphorylation of proteins, are still largely unknown. A phase I clinical trial has been terminated.

Iodohippuric acid I-125 (I-I25 Hippuran) is radioisotope that was used as a renogram probe in nefhrography in 1960s-1970s. It is an analog of I-131 labeled I(131) hippuran which has been recognized as the radiopharmaceutical standard for the measurement of effective renal plasma flow in subjects with renal failure but which use has been compromised by the suboptimal imaging characteristics of the 364-keV photon of 131I and the delivery of relatively high radiation doses to kidneys and thyroid in patients with impaired renal function. It was shown that radiation risk was rendered to a minimum with the use of the "cocktail" of 169U-EDTA and 125I-hippuran.
