TMC647055 is a potent and selective nonnucleoside inhibitor of NS5B binding site 1 (NNI-1) with activity against most HCV genotypes. Binding of inhibitors to NNI-1 is purported to displace the flexible λ1 loop from its thumb domain binding site, perturbing the interaction between the NS5B polymerase finger and thumb domains and thereby locking the enzyme in an open inactive conformation. Janssen R&D Ireland (formerly Tibotec Pharmaceuticals) is developing TMC 647055 as an oral once-daily treatment for chronic hepatitis C virus infections. Phase II development is underway in Belgium, Germany and the US.

LY377604 is a human β3-adrenergic receptor agonist and β1- and β2-adrenergic receptor antagonist with no sympathomimetic activity at the β1- and β2-adrenergic receptors. Combination of LY377604 and a norepinephrine-serotonin uptake inhibitor (sibutramine) was studied in the treatment of obesity. LY377604 would ameliorate side effect of sibutramine treatment (increase in blood pressure and heart rate due to activation of the sympathetic nervous system).

Fluoroacetic acid F-18 (18F-Fluoroacetate,18F-FAC) is an analog of acetate with a longer radioactive half-life (18F=110 min). Fluoroacetic acid F-18 was under investigation as a PET imaging agent. 18F-FAC was considered a promising alternative to 11C-ACE for positron tomographic imaging of prostate cancer, and possibly of other neoplasms with relatively low glucose use.

The labeled 4-IODOPHENYLALANINE I-131 is used for proteomics research. It’s also can be used for the chemoselective modification of proteins.

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.

Rigosertib sodium (ON 01910.Na) is a small molecule inhibitor of critical pathways important in the growth and survival of cancer cells, being developed by Onconova Therapeutics ("Onconova") for the treatment of hematologic malignancies and solid tumors. Rigosertib (ON-01910) is a non-ATP-competitive inhibitor of PLK1 with IC50 of 9 nM in a cell-free assay. It shows 30-fold greater selectivity against Plk2 and no activity to Plk3. Extensive Phase I and Phase II studies with rigosertib have been conducted at leading institutions in the U.S. and abroad in more than 450 patients with solid tumors and hematological cancers, including MDS and AML. MDS and AML are blood disorders widely recognized as difficult to manage, with limited therapeutic options available for patients, especially those with drug-resistant disease. The multi-site Phase III ONTIME trial in MDS patients is under a Special Protocol Assessment (SPA) from the U.S. FDA and is being supported by an award from the Therapeutics Acceleration Program (TAP) of the Leukemia and Lymphoma Society (LLS). FDA has granted Orphan Drug Designation for the use of rigosertib in MDS. The clinical program in solid tumors is also advancing with initiation of the Phase II/III combination ONTRAC trial (ON 01910.Na TRial in Patients with Advanced Pancreatic Cancer) and Phase II single agent trial in ovarian cancer. In Japan, SymBio is developing rigosertib for the treatment of refractory/relapsed HR-MDS (IV form) and first-line LR-MDS (oral form).

Apitolisib, a dual inhibitor of mTOR and phosphatidylinositol 3-kinase (PI3K), was being developed by Roche and Genentech as an orally administered therapy of cancer. Apitolisib is a selective, potent, orally bioavailable inhibitor of Class I PI3 kinase (PI3K) and mTOR kinase (TORC1/2) with excellent pharmacokinetic and pharmaceutical properties. Apitolisib displayed excellent potency against class I PI3K isoforms (IC50 PI3K-α, β, δ and γ = 4.8, 27, 6.7 and 14 nM) and mTOR kinase (IC50 = 17 nM) and selectivity against a large panel of other kinases. Apitolisib is in phase II trials by Genentech for the treatment of breast cancer, prostate cancer, endometrium cancer, kidney cancer. However, no recent development has been reported. It is also in phase I trials by Genentech for the treatment of non-Hodgkin's lymphoma.

FERMAGATE is a phosphate binder with phosphate plasma levels lowering activity. It is in Phase 3 development in the US and in Europe for the treatment of hyperphosphatemia in dialysis patients. It is made up of magnesium and ferric iron atoms held in an insoluble, rigid, crystalline-layered structure, with carbonate groups lying between the layers. Upon oral administration, the carbonate ions in FERMAGATE are exchanged for free phosphate ions released from food in the gastrointestinal tract; thereby, strongly binding phosphate. This inhibits phosphate uptake and preventing hyperphosphatemia.
