Publications
Development of a cell-based high-throughput assay to screen for inhibitors of organic anion transporting polypeptides 1B1 and 1B3.

Current chemical genomics

Gui C, Obaidat A, Chaguturu R, Hagenbuch B
Current chemical genomics - vol. 4 1-8 (2010)

The two organic anion transporting polypeptides (OATPs) 1B1 and 1B3 are expressed at the sinusoidal membrane of hepatocytes. They have a broad and overlapping substrate specificity and transport many endobiotics and drugs. Specific inhibitors are required to determine the contribution of each OATP to the hepatocellular uptake of common substrates. We have developed a cell-based […]

Pharmacological targeting of the mitochondrial phosphatase PTPMT1.

The Journal of pharmacology and experimental therapeutics

Doughty-Shenton D, Joseph JD, Zhang J, Pagliarini DJ, Kim Y, Lu D, Dixon JE, Casey PJ
The Journal of pharmacology and experimental therapeutics - vol. 333 584-92 (2010)

The dual-specificity protein tyrosine phosphatases (PTPs) play integral roles in the regulation of cell signaling. There is a need for new tools to study these phosphatases, and the identification of inhibitors potentially affords not only new means for their study, but also possible therapeutics for the treatment of diseases caused by their dysregulation. However, the […]

Drug reprofiling using zebrafish identifies novel compounds with potential pro-myelination effects

Neuropharmacology

Buckley CE, Marguerie A, Roach AG, Goldsmith P, Fleming A, Alderton WK, Franklin RJM
Neuropharmacology - vol. 59 149-159 (2010)

Treatment of the autoimmune demyelinating disease multiple sclerosis (MS) requires therapies that both limit and repair damage. While several immunomodulatory treatments exist to limit damage there are currently no treatments that promote the regenerative process of remyelination. A rapid way of screening potential pro-remyelination compounds is therefore required. The use of larval zebrafish in a […]

Journal of biomolecular screening - vol. 15 1051-62 (2010)

Cyclophilin A (CypA) is an overexpressed protein in lung cancer tumors and as a result is a potential therapeutic and diagnostic target. Described here is use of an H/D exchange- and a matrix assisted laser desorption/ionization (MALDI) mass spectrometry-based assay, termed single-point SUPREX (Stability of Unpurified Proteins from Rates of H/D Exchange), to screen 2 […]

The Biochemical journal - vol. 432 21-33 (2010)

The propensity of human embryonic stem cells to die upon enzymatic disaggregation or low-density plating is an obstacle to their isolation and routine use in drug discovery and basic research. Equally, the very low rate of establishment of implanted cells hinders cell therapy. In the present study we have developed a high-content assay for human […]

Schistosomiasis is a major tropical parasitic disease. For its treatment, praziquantel remains the only effective drug available and the dependence on this sole chemotherapy emphasizes the urgent need for new drugs to control this neglected disease. In this context, the newly characterized Schistosoma mansoni NAD+ catabolizing enzyme (SmNACE) represents a potentially attractive drug target. This […]

Prostate cancer is a leading cause of death among men due to the limited number of treatment strategies available for advanced disease. Discovery of effective chemotherapeutics involves the identification of agents that inhibit cancer cell growth. Increases in intracellular granularity have been observed during physiological processes that include senescence, apoptosis, and autophagy, making this phenotypic […]

Bioorganic and Medicinal Chemistry - vol. 17 7031-7041 (2009)

The sirtuin proteins are broadly conserved NAD+-dependent deacetylases that are implicated in diverse biological processes including DNA recombination and repair, transcriptional silencing, longevity, apoptosis, axonal protection, insulin signaling, and fat mobilization. Because of these associations, the identification of small molecule sirtuin modulators has been of significant interest. Here we report on high throughput screening against […]
