Advancing high content analysis towards improving clinical efficacy

16 February 2011 | By Neil Carragher, Edinburgh Cancer Research UK Centre, Institute of Genetics and Molecular Medicine, University of Edinburgh

High-content analysis is primed to play a prominent role in a new era of drug discovery research that places greater emphasis on clinical translation at all stages of the discovery process from target identification to proof-of-concept testing. High content analysis provides a technical bridge between reductionist targetdirected drug discovery approaches…

Establishing assays and small molecule screening facilities for Drug discovery programs

16 February 2011 | By Sheraz Gul, Vice President & Head of Biology, European ScreeningPort GmbH

Although many of the marketed small molecule drugs have been discovered by research and development efforts within the pharmaceutical industry, there has been a paradigm shift with external sources increasingly being relied upon to fill their pipelines. This trend is likely to increase and the key pre-clinical activities carried out…

Authentication of medicines using Raman spectroscopy

16 February 2011 | By Sulaf Assi, University of Hertfordshire, and Robert Watt & Tony Moffat, The School of Pharmacy, University of London

Raman spectroscopy offers a rapid and non-destructive technique for the identification of counterfeit medicines. Handheld Raman instruments offer the advantages of carrying the laboratory to the sample and giving a rapid pass or fail answer for the medicine inspected. It can identify a medicine regardless of its physical form as…

Application of flow cytometry in drug discovery

16 December 2010 | By Dana Buckman, Senior Scientist, Biomarkers – Translational Research, Pfizer

Flow cytometry can be used to advance our understanding of diseases in multiple ways. Drug effects and dosages can be ascertained in vitro, along with patient selection based on mutations and antigen profiles. Within the Diagnostic Biomarkers group of Translational Research at Pfizer, we are utilising flow cytometry in conjunction…

Developing and applying recombinant antibody microarrays for high-throughput disease proteomics

16 December 2010 | By Carl A.K. Borrebaeck and Christer Wingren, Department of Immunotechnology and CREATE Health, Lund University

Deciphering crude proteomes in the quest for candidate biomarker signatures for disease diagnostics, prognostics and classifications has proven to be challenging using conventional proteomic technologies. In this context, affinity protein microarrays, and in particular recombinant antibody microarrays, have recently been established as a promising approach within high-throughput (disease) proteomics1-3. The…

Applying PAT in pharmaceutical processes

1 November 2010 | By Mario Hellings, Tom Van den Kerkhof, Jeroen Geens and Steve Mehrman, Johnson & Johnson

As cited by the FDA, “Process Analytical Technology (PAT) is a system for designing, analysing, and controlling manufacturing through timely measurements (i.e., during processing) of critical quality and performance attributes of raw and in-process materials and processes with the goal of ensuring final product quality.”1 The main goal of PAT…

Advances in two-dimensional cell migration assay technologies

1 November 2010 | By Andreas Vogt, Department of Pharmacology and Chemical Biology and the University of Pittsburgh Drug Discovery Institute, University of Pittsburgh

Cell motility plays an important role in many human diseases and normal cellular processes. Cell migration is critical for wound healing as cells of the inflammatory system and fibroblasts populate the wound and initiate re-epithelialisation1. On the other hand, unregulated cell migration contributes to cancer cell invasion and metastasis2. Agents…

Bio-mimetic chromatography to predict drug distribution in vivo

29 October 2010 | By Klara Valko, Analytical Chemistry, GlaxoSmithKline Medicines Research Centre

A major concern for the pharmaceutical industry is the high attrition rate (>90 per cent) of potential drug molecules failing during late stages of the drug discovery process. This may be due to lack of efficacy in the clinic, unexpected side effects or unfavourable pharmacokinetics. There is a need for…

MS-based clinical proteomics: biomarker discovery in men’s cancer

29 October 2010 | By Brian Flatley Dept of Chemistry, University of Reading, Reading and Harold Hopkins Dept of Urology, Royal Berkshire NHS Foundation Trust Hospital, Reading and Peter Malone Harold Hopkins Dept of Urology, Royal Berkshire NHS Foundation Trust Hospital, Reading and Rainer Cramer Dept of Chemistry, University of Reading, Reading

Each year, approximately 10,000 men in the UK die as a result of prostate cancer (PCa) making it the third most common cancer behind lung and breast cancer. Worldwide, more than 670,000 men are diagnosed every year with the disease. Current methods of diagnosis of PCa mainly rely on the…
