Sources of Diversity

Many in the potato industry may be familiar only with solanine and chaconine, but estimates have been made that the potato family, including wild species, may contain about 90 GAs (Friedman and McDonald, 1997). In the course of LCMS characterization of small molecule diversity in tubers from diverse potato germplasm, we observed that GAs constituted a major source of diversity.

Recently, combinatorial technologies and libraries have somewhat replaced NPs as a source of diversity in pharmaceutical research. A comparison of combinatorial technologies with the fermentation of an NP-producing organism show that they both produce a library of compounds. While the former library is structurally determined a priori either by the selected synthetic scheme or by recombinant genetic information in the case of biosynthetic peptide and ON libraries, the latter is the result of the metabolic complexity of the producing strain and has to be deconvoluted in order to... 

The next issue in the drug discovery process following definition of target and sources of diversity is the definition of a lead structure. Lead structures can arise from biochemical or cell-based screens or through structure-based design. Broach and Thorner provide a more exhaustive description of screening strategies than is possible here (14). 

Three important issues need to be addressed for the successful implementation of combinatorial asymmetric catalyst design (i) sources of diversity, (ii) high throughput synthesis of catalysts, and (iii) high throughput catalyst screening. 

The reagents used and the products liberated are depicted in Table 5.1. From a single anchor structure and synthesis, different products can be generated with the use of different cleavage reagents providing a further source of diversity (e.g., with hydroxymethyl-benzoic acid as linker — five carboxylic acid derivatives). 

Figure 19.9. The ARCoEdit module. Operations are sample-specifically stored in a sample table, meaning that in each sample each operational step can tracked and edited by the user. Such a step comprises what is called a method , containing the requisite experimental procedures for a synthesis or purification step. This permits methods to be defined whose parameters can still be varied from sample to sample as a source of diversity. The pipetting volumes are calculated by the ARCoEdit module from the operant stoichiometries, as well as from the substance data stored in the substance database.

The preparation of indoles by the benzyne route is illustrated by the base-induced cyclization of the amino-alcohols (171 R = H or Me) to indole and 3-methylin-dole, respectively/ The photochemical reaction of o-bromo- or o-iodo-aniline with the enolates (172 R = H, Me, or PrO leads to indoles (173)/ The salt (174), generated by the action of lithium di-isopropylamide on o-tolyl isocyanide, serves as a source of diverse indole derivatives (i) it cyclizes spontaneously to 1-lithioindole, which forms 3-alkyl-indoles on treatment with alkyl halides in the presence of magnesium iodide, (ii) it reacts with allyl esters RC02CH2CH=CH2 (R = alkyl or aryl) to give the ketones (175), which cyclize... 

Sea lettuces are rich in nutrients with medicinal and health-promoting effect. From a nutritional standpoint, the main properties of sea lettuces are their richness in polysaccharides, protein and amino adds, fatty adds, minerals, and vitamins. Therefore, their nutritional value makes them valuable food supplements. Further, sea lettuces may be used to fortify processed foods. Food preparations from sea lettuces worldwide maybe studied to increase sea lettuce utilization. Moreover, recognition of sea lettuces as sources of diverse bioactive principles may open medicinal potential of sea lettuces and there is a great potential to be used in pharmaceuticals. Therefore, combination between culinary use and research on bioactive compounds may revitalize the use of sea lettuces in the newly health conscious consumers. Sea lettuce products could be used for food fortification, enrichment, and multipurpose applications. 

It is to be emphasized that the diverse topics presented in this book are integrated in such a fashion as to yield a coherent source of diverse but interrelated information for use by scientists, engineers, and clinicians who are interested in the use of A/BP in pharmaceutical and biomedical applications. The clinical components of the book are prepared by clinicians who are also well-versed scientists to maximize the effectiveness of integrating clinical with preclinical information.
