Markush Enumeration CT

    The Markush functions of the Chemical Terms language operate with Markush structures that cover a set of compounds with similar chemcal structures.


    We examine the displayed Markush structure:


    The general scaffold contains three R groups, but there is also an embedded R group assigned to this structure marked as R4.

    The number of possible structures can easily be given with Chemical Terms:


    According to this function, the number of possible compounds covered by this Markush representation is 18 .

    Using Markush functions, the whole compound set can be enumerated or emphasis can be put on a subset of molecules. Here, we generate three random molecules from the example Markush structure.


    These three molecules were enumerated as a result:
