Pharmaceuticals industrial applications

Although this book focuses on high-throughput analyses in the pharmaceutical industry, applications in environmental analysis are closely related. The same technologies are applicable to both fields. Pharmaceuticals have been monitored as pollutants in surface water, soil, food, and human plasma. In environmental applications, as many as 30 to 40 analytes have been monitored simultaneously. 

Unlike other methods currently employed for quantitative transcript measurements, including cDNA microarrays and real-time RT-PCR, competitive RT-PCR is amenable to quality control, which is critical for clinical diagnostic and pharmaceutical industry applications. Furthermore, microarray approaches are limited to generating snap-shot like profiles, but they do not control for differences in hybridization efficiencies of different gene probes with their corresponding cDNAs. That is, cross comparisons are relative and not absolute. Real-time PCR has gained acceptance recently largely due to the reduced cost associated... 

All the optically active terpenes mentioned in this chapter are commercially available in bulk (>kg) quantities and are fairly inexpensive. Although many of them are isolated from natural sources, they can also be produced economically by synthetic methods. Actually, two thirds of these monoterpenes sold in the market today are manufactured by synthetic or semi-synthetic routes. These optically active molecules usually possess simple carbocyclic rings with one or two stereo-genic centers and have modest functionality for convenient structural manipulations. These unique features render them attractive as chiral pool materials for synthesis of optically active fine chemicals or pharmaceuticals. Industrial applications of these terpenes as chiral auxiliaries, chiral synthons, and chiral reagents have increased significantly in recent years. The expansion of the chiral pool into terpenes will continue with the increase in complexity and chirality of new drug candidates in the research and development pipeline of pharmaceutical companies. 

Notably, however, despite the enthusiastic results evidenced by several research groups working in ILs chemistry, and the fact that the growing awareness of the pressing need for greener, more sustainable technologies has focused attention on the manufacture of fine chemicals and pharmaceutics, industrial applications are generally related to the production of bulk chemicals. ... 

There are a number of chemistry books available related to computational materials science and to modeling of molecular solid state, but none of the books cover current pharmaceutical industry applications. The intention of this book is to highlight the importance of the computational pharmaceutical solid-state chemistry and to fiU the gap in the current hterature. The book examines the state-of-the-art computational approaches to guide and analysis of solid form experiments and to optimize the physical and chemical properties of active pharmaceutical ingredient (API) related to its stability, bioavailability, and formulatability. While aU methods and approaches described in the book appear to be state of the art, the book is...

Food industry applications are confectionery, baking, fruit processing, composed foods, alcoholic beverages, soft drinks.The per-capita consumption of g in the USA (1997/98) was 9.4 kg. Pharmaceutical industry applications are medicated confectioneries, carriers and soft sweeteners for liquid medicines, coatings and binders for pills. The world production of g. in x 10 mt (1997/98) was 9.4 (USA 5.85, EU 1.9, Japan 0.85, others 0.8). There is generally a rising trend, caused by nonfood uses, mainly for antibiotics and chemicals via biotechnology.

Supercritical fluid extraction (SFE) has been widely used to the extraction processes in pharmaceutical industries. Besides application of SFE in phannaceuticals, it has been applied on a wide spectmm of natural products and food industries such as natural pesticides, antioxidants, vegetable oil, flavors, perfumes and etc [1-2]. 

The second method for mixture analysis is the use of specialized software together with spectral databases. We have developed a mixture analysis program AMIX for one- and multidimensional spectra. The most important present applications are the field of combinatorial chemistry and toxicity screening of medical preparations in the pharmaceutical industry. An important medical application is screening of newborn infants for inborn metabolic errors. 

The precious metals are many times the cost of the base metals and, therefore, are limited to specialized applications or to those in which process conditions are highly demanding (e.g., where conditions are too corrosive for base metals and temperatures too high for plastics where base metal contamination must be avoided, as in the food and pharmaceutical industries or where plastics cannot be used because of heat transfer requirements and for special applications such as bursting discs in pressure vessels). The physical and mechanical properties of precious metals and their alloys used in process plants are given in Table 3.38. 

Examples of Synthesis Routes Inherently Safer Than Others As summarized by Bodor (1995), the ethyl ester of DDT is highly effective as a pesticide and is not as toxic. The ester is hydrolytically sensitive and metabolizes to nontoxic products. The deliberate introduction of a structure into the molecule which facilitates hydrolytic deactivation of the molecule to a safer form can be a key to creating a chemical product with the desired pesticide effects but without the undesired environmental effects. This technique is being used extensively in the pharmaceutical industry. It is applicable to other chemical industries as well. 

The Kolbe-Schmitt reaction is limited to phenol, substituted phenols and certain heteroaromatics. The classical procedure is carried out by application of high pressure using carbon dioxide without solvent yields are often only moderate. In contrast to the minor importance on laboratory scale, the large scale process for the synthesis of salicylic acid is of great importance in the pharmaceutical industry. 

Combinatorial chemistry, a new chapter of organic synthesis, is now developing rapidly. This new approach to synthesizing large designed or random chemical libraries through application of solid phase synthetic methods, promises to revolutionize the process of drug discovery in the pharmaceutical industry.24... 

In a catalytic asymmetric reaction, a small amount of an enantio-merically pure catalyst, either an enzyme or a synthetic, soluble transition metal complex, is used to produce large quantities of an optically active compound from a precursor that may be chiral or achiral. In recent years, synthetic chemists have developed numerous catalytic asymmetric reaction processes that transform prochiral substrates into chiral products with impressive margins of enantio-selectivity, feats that were once the exclusive domain of enzymes.56 These developments have had an enormous impact on academic and industrial organic synthesis. In the pharmaceutical industry, where there is a great emphasis on the production of enantiomeri-cally pure compounds, effective catalytic asymmetric reactions are particularly valuable because one molecule of an enantiomerically pure catalyst can, in principle, direct the stereoselective formation of millions of chiral product molecules. Such reactions are thus highly productive and economical, and, when applicable, they make the wasteful practice of racemate resolution obsolete.

Notwithstanding the chemical differences (alcohol groups in guaran, carboxyl groups in xanthan, and partially esterified carboxyl groups in pectin) these three polysaccharides in combination with chitosan in the microspheres appear to be able to bring chitosan into solution. This is particularly interesting if one considers the solubility of these three polysaccharides in water and their important applications in the food and pharmaceutical industries. 

Of major concern are the health and environmental impacts of the abundant chlorinated and brominated hydrocarbons (ref. 2). These materials have numerous industrial applications as pesticides, solvents, propellants, refrigerants, plastics, fire retardants and extinguishers, disinfectants for drinking water, pharmaceuticals and electronic chemicals. Many chemical manufacturers utilize chlorinated and brominated organics as intermediates. It is estimated, for instance, that almost 85 % of the pharmaceuticals produced in the world require chlorine at some stage of synthesis.
