LXR-623 is a is a highly selective and orally bioavailable synthetic agonist of Liver X receptors (LXR) alpha and beta that has shown promise in animal models of atherosclerosis. In nonhuman primates with normal lipid levels, LXR-623 significantly reduced total (50-55%) and LDL-cholesterol (LDLc) (70-77%) in a time- and dose-dependent manner and increased expression of the target genes ABCA1 and ABCG1 in peripheral blood cells of rats, mice and monkeys. LXR-623 demonstrated efficacy for reducing lesion progression in the murine LDLR(-/-) atherosclerosis model with no associated increase in hepatic lipogenesis either in this model or Syrian hamsters and displayed a unique and favorable pharmacological profile suggesting it may be suitable for evaluation in patients with atherosclerotic dyslipidemia. Results from a single ascending-dose study of the safety, pharmacokinetics, and pharmacodynamics of LXR-623 in healthy humans confirmed the effect of LXR-623 concentration on ABCA1 and ABCG1 expression. LXR-623 was absorbed rapidly with peak concentrations (Cmax) achieved at about 2 hours and increased Cmax and area under the concentration-time curve in a dose-proportional manner. The mean terminal disposition half-life was between 41 and 43 hours independently of dose. Central nervous system—related adverse events were observed at the 2 top doses tested. LXR-623 showed brain penetration and caused tumor regression in a glioblastoma (GBM) mouse model which characterize it as a potentially potent, highly-specific anti-GBM therapy.

Gadocoletic acid (also Gadoletic acid trisodium salt, or B22956/1) is a magnetic resonance contrast agent. Based on results from animal imaging experiments and pharmacokinetic data it was suggested that gadocoletic acid trisodium salt has strong potential for clinical use in Magnetic Resonance Coronary Angiography and Myocardial Perfusion Imaging. The small molecules of gadocoletic acid are bound after injection to large human serum albumin molecules in coronary vessels with the result of high vessel/muscle contrast. The ability of B229563− (anion) to bind to more than one site on the albumin molecule allows a positive correlation between dose and blood relaxation rate enhancement at doses higher than 0.05 mmol/kg, the dose that produces roughly a total plasma concentration equimolar to the albumin concentration at equilibrium distribution. Gadocoletic acid is thought to be highly efficacious in inversion recovery-prepared 3D gradient-recalled echo, navigator echo-gated coronary angiography in humans already at doses below 0.1 mmol/kg.

Sodium aceneuramate is a sodium salt of aceneuramic acid (sialic acid). It is an effective inhalant expectorant. Inhalation of sodium aceneuramate repaired inflammation in the airway, and caused bronchitic rabbits to produce sputa with a low viscosity, similar to normal air-way secretions. Sodium aceneuramate protected the mucociliary transport impaired bycigarette smoke in a dose-dependent manner. The results suggest that sodium aceneuramate may participate in the defense mechanism in the airway against irritant gases. Sodium aceneuramate inhibited bronchial anaphylaxis and the release of histamine into bronchoalveolar lavages. Sodium aceneuramate has an action which elevates the viscoelasticity of secretions in the respiratory tract.

Lobucavir is a new anti-cytomegalovirus infection agent, manufactered by Bristol Myers Squibb, Inc. Lobucavir is a cyclobutyl analog of guanine with broad spectrum antiviral activity against most herpes viruses and Hepatitis B. Lobucavir was shown to inhibit herpes simplex virus (HSV) DNA polymerase after phosphorylation by the HSV thymidine kinase. The drug was well tolerated with few side effects. Lobucavir had been in phase III clinical trial for the treatment of Hepatitis B, Herpes simplex virus infections and in phase II for the treatment of Cytomegalovirus infections. All these studies were discontinued.

Luminespib (NVP-AUY922) is a highly potent isoxazole-based, nongeldanamycin HSP90 inhibitor that inhibits the adenosine triphosphatase activity of
HSP90. Luminespib is a highly potent HSP90 inhibitor for HSP90α/β with IC50 of 13 nM /21 nM in cell-free assays, weaker potency against the HSP90 family members GRP94 and TRAP-1, exhibits the tightest binding of any small-molecule HSP90 ligand. Luminespib potently inhibited in vitro growth in all 41 NSCLC cell lines evaluated with IC50 less than 100 nM. IC100 value less than 40 nM was seen in 36 of 41 lines. Luminespib (NVP-AUY922) has greater potency, reduced hepatotoxicity, and lower dependence on DT-diaphorase than the first-generation HSP90 inhibitors. Luminespib was discovered in a multiparameter lead optimization program based on a high-throughput screening hit methodology developed jointly by The Institute of Cancer Research, UK and the pharmaceutical company Vernalis. It has been licensed to Novartis. Luminespib activity is independent of NQO1/DT-diaphorase, maintained in drug-resistant cells and under hypoxic conditions. The molecular signature of HSP90 inhibition, comprising induced HSP72 and depleted client proteins, was readily demonstrable. Pre-clinical studies proved that Luminespib acts via several processes (cytostasis, apoptosis, invasion, and angiogenesis) to inhibit tumor growth and metastasis. These results helped Luminespib to enter clinical trials for various cancers including breast cancers. From 2011 to 2014 it was in Phase II clinical trials.

Clevudine F18 is a radioconjugate comprised of the synthetic pyrimidine analog clevudine (1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)thymine, d-FMAU) labeled with the radioisotope fluorine F18. Upon administration, fluorine F18 clevudine is distributed and taken up by cells based on the rate of the cell’s DNA synthesis. The amount is then measured using positron emission tomography (PET). The compound is investigated as an imaging agent in prostate, breast cancers, and other malignant neoplasms.
