Markush Enumeration Plugin

A Markush structure is a description of a compound class by generic notations, primarily used in patent claims and the description of combinatorial libraries. The library of a Markush structure is the total set of specific molecules that are described by the Markush structure.

The Markush enumeration plugin can be used to generate a whole or a subset of the library of a generic Markush structure. It is also capable of calculating the total number of specific structures present in a Markush library.

The plugin handles the following combinatorial Markush features: R-groups, atom and bond lists and link nodes.

Markush Search

Markush Search is an add-on to JChem Base and Instant JChem and allows the registration of generic structures into the database as well as substructure and exact structure searching in their enumerated libraries (without enumeration of library members). More information.
