Daylight Toolkits

The compact textual coding requires no graphical input and additionally permits a fast transmission. These are important advantages of using SMILES in chemical applications via the Internet and in online services. SMILES is also used for the input of structures in the Daylight Toolkit [22].

More recently, Hajduk and Sauer analyzed the molecular transformations in Abbott Laboratories in-house data (84 000 structures) and their effect on the potency against 30 proteins [23]. They generated the matched molecular pairs using an algorithm based on the MCS function provided by the Daylight Toolkit Their analysis was limited to chemically sensible transformations, such as group additions (i.e., H 3> Y) and multiple region-specific phenyl substitutions. The results illustrated that no transformation seemed to consistently favor potency increase.

A second eccentricity is that atom labels are drawn smaller when in rings. Additionally, whereas it is customary to omit the C atom label for carbon atoms, DEPICT provides them everywhere except in aromatic rings. Aromatic atoms, in turn, are written in lowercase, betraying a kinship to SMILES notation. These peculiarities detract somewhat from the diagram s aesthetic appearance however, they probably reflect the defaults used to visualize SMILES. Reportedly, the defaults can be replaced by adjustable parameters within the Daylight Toolkit.

Scheme 10.7. Systematic search for novel MCRs by using the Daylight reaction toolkit on a reaction database.

Scheme 10.8. The application of a chemistry reaction knowledge base, using the Daylight reaction toolkit, provides new proposals for novel scaffolds.

DEPICT has been rewritten several times over the years, though the basic approach remains the same. " From this and as a result of numerous extensions by Daylight and its user group, made possible by the Toolkit s open architecture, have appeared many new features, albeit scattered among various versions. These features are listed as follows.
