WebNov 28, 2024 · RDKit is an open-source cheminformatics software that can convert molecule structures into vectors. Then, the vectors are stored in Milvus and Milvus can perform similarity search on vectors. Milvus also automatically generates a unique ID for each vector. The mapping of vector IDs and structure of molecules are stored in MySQL. WebMay 18, 2024 · The goal here is to systematically come up with some guidelines that can be used for fingerprints supported within the RDKit. We will do that by looking a similarities between random “drug-like” (MW<600) molecules picked from ChEMBL. For the analysis, the 25K similarity values are sorted and the values at particular threshold are examined.
