Cell-based imaging

28 September 2006 | By Jinghai J. Xu, Ph.D., Margaret C. Dunn, Arthur R. Smith, Pfizer Global Research and Development

Traditionally, in vivo histopathological findings have been used as part of standard readouts for safety assessment of new chemical entities (NCEs). The process typically involves dosing animals with NCEs for varying amounts of time, harvesting their major organs at the end of the study, preparing tissue sections and slides and…


Identifying human toxicity potential

20 July 2006 | By Dolores Diaz, CEREP and Peter J. O’Brien, Safety Sciences Europe, Pfizer Global R&D

The statins (3-hydroxy-3-methylglutaryl coenzyme A [HMG-CoA] reductase inhibitors) are drugs that inhibit cholesterol biosynthesis by blocking the formation of the cholesterol precursor mevalonate. Statins are the most effective cholesterol-lowering agents available and are considered the first line of treatment for most patients with high serum cholesterol levels1.


The promise of pancreatic beta cells

20 May 2005 | By William Carley, Ph.D., Experimental Medicine, Pfizer Global R&D

Biomarker application during drug development is driven by the need to define disease and therapeutic efficacy/safety earlier, better and with reduced cost.


Evaluating drug safety

7 March 2005 | By Donald G. Robertson, Metabonomics Evaluation Group, Departments of Worldwide Safety Sciences and Michael D. Reily, Discovery Technologies, Pfizer Global Research and Development

Metabonomics has been defined as the “the quantitative measurement of the time-related multi-parametric metabolic response of living systems to pathophysiological stimuli or genetic modification”1. In simple terms it is a powerful tool for assessing the metabolic component of systemic response.
