Specify your query (either by drawing or by providing a chemical identifier such as mcule ID, SMILES, InChI or InChIKey)
If you want to keep a particular substructure in all resulting analogs, modify your query accordingly (delete unnecessary parts) and select “Substructure” search type. Note: you can block substituents at particular positions of the molecule by placing explicit hydrogen atoms.
If you simply want the overall most similar analogs of your compound, select “Similarity” search type
Click on “SEARCH”
After the search was finished and the most similar compounds were displayed, click on the orange “QUOTE” button in the top right corner
