Pharmaceutical process development background

On the other hand, the historical perspective and operation of supercritical extraction was intended to supply the background to serve as an aid in appreciating the motivation for the current activities, not just in flavors extraction and characterization but for the process development being carried out in the chemical, food, pharmaceutical, and polymer industries. 

With background information, assays, and sample preparation and extraction procedures in place the Three Phase Purification Strategy can be applied (Figure 3). This strategy is used as an aid to the development of purification processes for therapeutic proteins in the pharmaceutical industry and is equally efficient as an aid when developing purification schemes in the research laboratory. 

Numerous factors are responsible for the recent paradigm shift in the drug discovery and development process. First, and foremost, is the cost factor. The pharmaceutical industry can no longer sustain their former business model in the context of the exponential growth in costs associated with drug development as widely described by the investigators at Tufts University [1]. With this background we add the remarkable productivity of combinatorial chemistry... 

The purpose of this review is to provide the reader with a brief introduction to the background and to some of the more recently developed applications of molecular surfaces. Some of these developments are related to the concept of molecular shape, which is of fundamental importance in the analysis of similarities, regularities, and correlations among molecules and in the modeling of chemical and biochemical processes. The study of molecular surfaces has predictive value in various fields of chemistry.In particular, pharmaceutical drug design, toxicity analysis, and the development of new... 

To provide background information for the role of synthetic chemistry, some aspects of the R D process in innovative pharmaceutical companies deserve comment. The complexity of the usual multidisciplinary research process in developing an NDE is presented schematically in Fig. 1.1.
