WebFeb 28, 2024 · So, in RDKit, if you convert smiles_1a to mol and this mol back to SMILES again, you get c1ccc2c (c1)-c1cccc3cccc-2c13. If you search with this, you will still not find structures 3 and 5. Probably because of the defined single bonds. However, if you replace - by ~, you get smiles_1b: c1ccc2c (c1)~c1cccc3cccc~2c13. WebApr 5, 2024 · To accomplish these tasks, open source libraries like RDKit are frequently used to analyze molecular data for insights.
