Although most applications were of the cherry-picking type design, the combinatorial design of new chemical libraries should also be feasible. In this case, the scores obtained with the various models can be used to sort the virtual library, followed by building block frequency analysis cf. Focus2D) to determine which reagents should be used in chemical synthesis. Alternatively, combinatorial optimization approaches, such as those in described in ref. 4, can be applied where the model-predicted scores are used as the objective function for optimization. 

In place of the previously recommended Available File Item statement, APA now recommends a statement identifying the date of retrieval (omit for CD-ROM) and the source (e.g., Electric Library), followed in parentheses by the name of the database and any additional information that helps locate the material. For Web sources, a URL should cite the entry page for the database. 

Curran et alls work informs us that construction of stereoisomer libraries followed by thorough studies on their NMR and enantioselective HPLC behaviors is an especially reliable way of elucidating the stereostructure of natural products. This type of thorough stereochemical analysis is likely to become more popular in the future in connection with the advances in parallel synthesis. 

The synthetic advantages of preparing mixtures instead of individual compounds are offset by the need to deconvolute mixture libraries following bioassay. Deconvolution shortcuts, such as synthesis of multiple libraries containing orthogonal pools (36), are sometimes useful but can only be relied on when the activity of the mixture results from a single highly active compound.

To select for increased thermal stability in an error-prone library, follow the protocol in Subheading 3.2.5, steps 1-3. Next, proceed as follows ... 

The design of lead-finding libraries follows the same molecular mimicry principles and makes the best use of the substantial medicinal chemistry... 

The design of enzyme inhibitors has included random screening of synthetic chemical agents, natural products, and combinatorial libraries followed by molecular optimization or structure-activity relationships of so-called lead structures as well as bio-isosteric analogues of the enzyme substrates themselves. Drugs (e.g., finasteride) also have been developed for one indication but, based on observed side effects, have lead to other uses. 

Following the destruction of alchemical works by Diocletian, the famous Library of Alexandria was itself burnt to the ground by a Christian mob in 390CE. This loss of the Library, followed by the gruesome murder of the beautiful mathematician Hypatia by a gang of monks twenty-five years later, ushered in Europe s Dark Ages. 

Combinatorial chemistry and combinatorial technologies fall into a new interdisciplinary field joining combinatorial informatics with automated synthesis of chemical "libraries" followed by automated screening, with the main output in medicinal chemistry and drug discovery. This nascent technology has produced more new compormds in just a few years than the pharmaceutical industry did in its entire previous history. 

FENDL is a Fusion Reactor Technology Evaluated Nuclear Data Library Project coordinated by the IAEA Nuclear Data Section specifically for the ITER Fusion Project. Files are selected fi-om the available libraries following validation studies. 

The number of good soup recipes would, literally speaking, stretch around the world. Usually the soup is named after the ingredients, but there are some world-famous soups with which everyone should become acquainted, unless they are already old friends. Some of these, the recipes for which can be found in the local cookbook library, follow ...
