Linarotene is arotinoid derivative. It is an antikeratolytic agent. Linarotene had been in preclinical phase by Ortho Pharmaceutical (Johnson & Johnson) and BASF Pharma for the treatment of skin disorders. However, this research was 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.

BGT 226 is an orally available, small molecule, the dual inhibitor of mammalian target of rapamycin (mTOR) and phosphatidylinositol 3'kinase (PI3K), developed by Novartis for the treatment of solid tumors, including advanced breast cancer. A phase I/II trial was completed in the US, Canada, and Spain, and a phase I trial was completed in Japan. However, development appears to have been discontinued.

PF-03654764 binds with high affinity to the human H3 receptor and with lower affinity to the rat H3 receptor, in addition to having >1000-fold selectivity versus other human histamine receptor subtypes (H1, H2, and H4). PF-03654764 displayed potent antagonist properties in functional assays measuring cAMP utilizing a reporter gene assay (β-lactamase) in HEK293 cells stably expressing full length human or rat H3 receptors. In human hepatic microsomes, PF-03654764 was metabolically stable and were predicted to have low clearance. It has low potential to inhibit activities of CYP 1A2, 2B6, 2C8, 2C9, 2C19, 2D6, and 3A4. PF-03654764 + fexofenadine failed to provide superior relief of allergic rhinitis-associated nasal symptoms upon exposure to ragweed pollen compared to fexofenadine + pseudoephedrine. Side effects in the PF-03654764-treated groups were clinically significant compared to the controls. PF-03654764 had been in phase II clinical trial for the treatment of allergic rhinitis and in phase I clinical trial for the treatment of Alzheimer's disease. However, these investigations were discontinued.

Stilbazium is a pyridinium derivative with considerable anthelminthic activity against some animal nematodes, including Syphacia obvelata, Ancylostoma caninum, Uncinaria stenocephala and Toxocara cati.

AZD-7687 is a potent inhibitor of Diacylglycerol O-acyltransferase 1 (DGAT1) which was developed by AstraZeneca for the treatment obesity and type 2 diabetes mellitus. AZD-7687 reached phase I of clinical trials, but was discontinued by unknown reasons.

Amgen was developing AMG-208, a small molecule inhibitor of c-Met, for the treatment of cancer. AMG-208 shows the potent inhibition of kinase c-Met activity with IC50 of 9 nM in a cell-free assay. Besides, AMG-208 treatment also leads to the inhibition of HGF-mediated c-Met phosphorylation in PC3 cells with IC50 of 46 nM. AMG-208 showed evidence of antitumor activity, particularly in prostate cancer. On December 1, 2014 Amgen completed a phase I trial in solid tumours.

Saroglitazar, a dual peroxisome proliferator-activated receptor PPAR-α/γ agonist, was an emerging therapeutic option on glycemic and lipid parameters. The Zydus Group has launched LipaglynTM ((Saroglitazar) in India for diabetic dyslipidemia and hypertriglyceridemia with type 2 diabetes mellitus not controlled by statin therapy. In addition, saroglitazar participated in phase II clinical trials that completed enrolment in patients with primary biliary cholangitis and in patients with non-alcoholic steatohepatitis.
