Library biological

The last library position remains physically determined by the last splitting, simplifying the deconvolution of the library. Biological screening of the final pools A B Ci, A B C2 and A B C3 (Figure 8.3) identifies the best monomer of... 

The World Wide Web Virtual Library Biosciences points to virtual library pages for Biological Molecules, and Biochemistry and Molecular Biology. Each of these pages presents a long list of Web resources. The World Wide Web Virtual Library Biological Molecules covers molecular sequence and structure databases, metabolic pathway databases, and other lists of Web resources. The World Wide Web Virtual library Biochemistry and Molecular Biology is a list of resources, listed by provider. 

In essence only two approaches exist to generate combinatorial peptide libraries biologic and synthetic library approaches. According to the different techniques used, the synthetic library approach can be divided additionally into five methods 1) the spatially addressable parallel library method (1, 4, 8),...

Diverse libraries can be used for lead finding by screening against several different targets. The selected compounds should cover the biological activity space well.

Chemoinformatics (or cheminformatics) deals with the storage, retrieval, and analysis of chemical and biological data. Specifically, it involves the development and application of software systems for the management of combinatorial chemical projects, rational design of chemical libraries, and analysis of the obtained chemical and biological data. The major research topics of chemoinformatics involve QSAR and diversity analysis. The researchers should address several important issues. First, chemical structures should be characterized by calculable molecular descriptors that provide quantitative representation of chemical structures. Second, special measures should be developed on the basis of these descriptors in order to quantify structural similarities between pairs of molecules. Finally, adequate computational methods should be established for the efficient sampling of the huge combinatorial structural space of chemical libraries.

Combinatorial chemistry (Section 27.18) A method for carrying out a large number of reactions on a small scale in the solid phase so as to generate a library of related compounds for further study, such as biological testing. 

In addition to the development of the powerful chiral additive, this study also demonstrated that the often tedious deconvolution process can be accelerated using HPLC separation. As a result, only 15 libraries had to be synthesized instead of 64 libraries that would be required for the full-scale deconvolution. A somewhat similar approach also involving HPLC fractionations has recently been demonstrated by Griffey for the deconvolution of libraries screened for biological activity [76]. Although demonstrated only for CE, the cyclic hexapeptides might also be useful selectors for the preparation of chiral stationary phases for HPLC. However, this would require the development of non-trivial additional chemistry to appropriately link the peptide to a porous solid support. 

The challenge in the synthesis of chemical libraries is the vast number of different, potentially drug-like small molecules which is estimated to be as high as 1060. As all of these molecules can never be synthesized and tested, it is essential to define criteria for the composition of libraries spanning the biologically relevant areas of the chemical space most efficiently. An important criterion of a compound library is its chemical diversity, a term describing the similarity or dissimilarity of all library components. Thus, chemical diversity expresses how well a library represents all theoretical possibilities within the chemical property space. A library with low...
