RESUMO
Increasing pressure on the pharmaceutical industry to reduce cost and focus internal resources on "high value" activities is driving a trend to outsource traditionally "in-house" drug discovery activities. Compound collections are typically viewed as drug discovery's "crown jewels"; however, in late 2007, Johnson & Johnson Pharmaceutical Research & Development (J PRD) took a bold step to move their entire North American compound inventory and processing capability to an external third party vendor. The authors discuss the combination model implemented, that of local compound logistics site support with an outsourced centralized processing center. Some of the lessons learned over the past five years were predictable while others were unexpected. The substantial cost savings, improved local service response and flexible platform to adjust to changing business needs resulted. Continued sustainable success relies heavily upon maintaining internal headcount dedicated to vendor management, an open collaboration approach and a solid information technology infrastructure with complete transparency and visibility.

Determination of drug distribution in brain and other tissues is important in pharmaceutical research. Tissue drug levels need to be determined routinely as they are usually diagnostic for both efficacy and toxicity. Determination of tissue levels in small organ subregions is frequently performed due to important functional considerations. These measurements have traditionally been very tedious requiring extensive dissection and specimen pooling to achieve detection of analytes of interest. Direct and indirect methods utilizing mass spectrometry have been reported for detection of analytes in tissue specimens. Typically, these require very specialized MS or sampling equipment and are only partially successful due to analyte response. We have developed a novel approach for quantitation of tissue sections called Functional Tissue Microanalysis (FTM) in which small circular samples are removed from subregions of interest, extracted and analyzed by conventional LC/MS/MS utilizing electrospray ionization. This allows direct measurement of regional concentrations without dissection and homogenization of tissue specimens as many subregions can be sampled from a single mounted section. Utilization of the FTM approach for analysis of both sagittal and coronal rat brain sections is shown for quantitation of raclopride and rimonabant. Reproducibility of this approach and comparison to conventional methods is reported.
