Composing Markush structures

From a list of compounds, you can automatically generate an initial Markush structure. All generalizations and modifications can be done in an intuitive editor using the clear and easy-to-use hierarchical R-group representation. During manual modifications, the automatic analysis identifies any mistakes or inconsistencies, and gives instant feedback about the coverage of your Markush structure.

Furthermore, exporting to claim text format saves hours of time by automatic generation of the backbone of your claims and also avoids mistakes in the description of the R-groups. Markush Editor features exclusive and efficient tools for all Markush-related tasks.

Creating a Markush structure based on a list of compounds is the first step in your Markush claim drafting process. Markush Editor can find the optimal scaffold and generate all R-group definitions automatically. Even for hundreds of structures, the automatic generation takes only seconds. Various Markush features and the main parameters of the generation process can easily be configured according to your requirements or preference.

Hierarchic R-group representation

Markush Editor offers unique, hierarchical 'tree-like' visualization of R-group relationships in Markush structures, making navigating through R-groups and understanding a Markush structure much easier. All the nodes of the 'tree' are editable, making any modification in this way safe and intuitive.

Interactive Markush analysis

During the drafting process, it is essential to know whether your compounds are covered by the Markush structure or not. To achieve this, compound lists can be loaded into Markush Editor, and they are continuously validated against the Markush structure. The search follows all modifications, so the editor will show real-time feedback about whether and how the compounds match the Markush structure. Advanced hit and non-hit visualization of compounds makes it straightforward to see the matching parts of them, and also highlights the differences. Any logical errors, like missing R-groups or circular references are also indicated.

Generating Markush claims text

At the end of the day, you want to see your claim in the form of a scaffold image followed by the text description of your R-groups. Markush Editor can automatically generate you the group definition lists and help avoid any manual errors. Instead of writing endless lists of substituents, you can focus on the perfect legal wording of your claims.
