Import SMILES

If the SMILES does not display after clicking 'Import SMILES' try importing directly on the MarvinJS sketch tool. Click the second from left icon on the top row (or use ctrl-O). Importing in this way will give an error if the SMILES is invalid.

To return all relevant hits please ensure that your input structure does not include chiral specification.

2. Choose type of search to perform Exact (Isomorph) Substructure Similarity: high (>85%) Similarity: moderate (>70%) Similarity: low (>50%) SMARTS
