GSK-2269557 (nemiralisib), a PI3Kδ inhibitor, is in development as an anti-inflammatory drug for the treatment of inflammatory airways disease. Studies in moderate or severe stable COPD patients have shown an acceptable safety and tolerability profile when GSK-2269557 was administered via inhalation. Cough was the most commonly reported adverse event.

GSK-1482160 is being evaluated for treatment of inflammatory pain (such as arthritis). This compound acts on P2X7 receptors, expressed by cells of innate and adaptive immunity. P2X7 receptors are involved in the production of pro-inflammatory cytokines that are thought to be an important mediator of inflammation. By blocking P2X7 receptors, less inflammatory chemicals are released, which possibly results in less inflammatory pain. Because of its ability to target P2X7R with high selectivity and to be radiolabelled with 11C, GSK-1482160 was suggested to be a useful biomarker for neuroinflammation via positron emission tomography (PET).

LY2811376 is a non-peptide inhibitor of BACE1 selective over BACE2. It showed robust central reduction of amyloid-β in humans.

GLPG0187 is a compound that belongs to the class of organic compounds known as naphthyridines, and has been studied as a potential drug in the treatment of solid tumors. GLPG0187 is a broad spectrum integrin receptor antagonist that inhibits αvβ1 integrin. In vitro, this compound was found to diminish the size of the aldehyde dehydrogenase high subpopulation of prostate cancer cells dose-dependently. It also significantly reduced tumor cell migration and cell proliferation. In vivo, it reduced metastatic tumor growth, and inhibited the progression of bone metastases as well as the formation of new bone metastases. Phase I studies have been completed to study safety and drug tolerance of GLPG0187. The drug was well tolerated, but continuous infusion of GLPG0187 did not show signs of monotherapy efficacy.

13-deoxyadriamycin hydrochloride (13-Deoxydoxorubicin hydrochloride, GPX-100) is an anthracycline similar to doxorubicin. GPX-100 is unique among anthracyclines because it is not converted to doxorubicinol during metabolism in the body. This metabolite has been shown to be a major cause of damage to the heart (cardiotoxicity) in laboratory studies. GPX-100 belongs to the class of reactive oxygen species stimulants; RNA synthesis inhibitors and Type II DNA topoisomerase inhibitors. It was in phase II clinical trial for the treatment of cancer.

F-901318 (Olorofim) is an orotomide antifungal drug. An investigation into the mechanism of action of F-901318 found that it acts via inhibition of the pyrimidine biosynthesis enzyme dihydroorotate dehydrogenase (DHODH) in a fungal-specific manner. Olorofim is being developed by F2G for the treatment of mycoses.
