Abstract
Abstract: This dataset is a subset of the ZINC15 database, specifically filtered and processed for molecular similarity search applications using MegaMolBART embeddings. The subset focuses on drug-like molecules with specific physicochemical and purchasability properties.
Keywords: ZINC15, Molecular Similarity Search, MegaMolBART, Drug Discovery, Cheminformatics.
Background: The ZINC15 database is a comprehensive collection of commercially available compounds for virtual screening. This subset was created to facilitate the development of machine learning models for drug discovery, particularly those based on molecular embeddings.
Methodology: The ZINC15 database was queried using the following criteria:
- Molecular weight <= 500 Daltons
- LogP <= 5
- Reactivity level = "reactive"
- Purchasability = "annotated"
The resulting dataset was then processed to extract MegaMolBART embeddings for each molecule.
Data Description:
The dataset is organized into three folders:
- /data/project/ubrite/drg-depot/zinc15-similarity-search/raw-data/ (66 GB): This folder contains the raw data files obtained from the ZINC15 database after applying the filtering criteria.
- /data/project/ubrite/drg-depot/zinc15-similarity-search/processed-data/ (13 GB): This folder contains the processed data, including the extracted MegaMolBART embeddings for each molecule.
- /data/project/ubrite/drg-depot/zinc15-similarity-search/query/: This folder contains sample SMILES strings and their corresponding embeddings for performing similarity searches.
Technical Specifications:
- Format: SMILES strings, numerical data (embeddings)
- Size: 79 GB (total)
