Scaffold-based Classification Approach

In addition, there have also been a number of efforts to find more efficient ways to categorise and enumerate compounds. One approach to defining the relationship of compounds to each other uses a chemical space defined by a set of 500 compounds described with 60 molecular descriptors onto which novel compounds can then be mapped.116 Another approach that has been described uses a rule-based classification scheme to define the common scaffold or core of compounds.117 This approach has been taken further to develop a scoring function to allow the prioritisation of compound libraries for testing.118...
