Release v2.0.0

This release extends KinFragLib by adding CustomKinFragLib which enables the filtering of the fragment library based on chemical properties, unwanted substructures, and synthesizability. We include new notebooks and the filtered CustomKinFragLib fragment library.

New Notebooks

• Custom filtering steps
  • 1_1_custom_filters_unwanted_substructures.ipynb: filters based on unwanted substructures (PAINS and Brenk et al)
  • 1_2_custom_filters_drug_likeness.ipynb: filters based on Ro3 and QED score
  • 1_3_custom_filters_synthesizability.ipynb: filters based on SYBA score and buyable building block matching
  • 1_4_custom_filters_pairwise_retrosynthesizability: filter based on retrosynthetic pathways using ASKCOS
• Custom filtering pipeline
  • 2_1_custom_filters_pipeline.ipynb: applies all filters step by step
  • 2_2_custom_filters_analysis.ipynb: analysis on custom-filtered fragment library
  • 2_3_custom_filters_papers.ipynb: generates figures used in the paper

Release v1.1.0

New release of repository containing data and notebooks for the publication KinFragLib: Exploring the Kinase Inhibitor Space Using Subpocket-Focused Fragmentation and Recombination.

New

• Added GitHub Actions CI running all notebooks with pytest (combinatorial dataset is downloaded from zenodo)
• Made the former notebooks/utils.py script pip-installable as kinfraglib (utility functions can now be used outside of notebooks folder)
• Add PR template
• New notebooks:
  • Highlight subpocket fragments in ligands based on Greg's blog post: 2_4_highlight_fragments_in_ligand.ipynb
  • Show how to generate molecules from the combinatorial library: 4_5_combinatorial_library_construct_ligands.ipynb

Updates

• Changed KLIFS queries from klifs_utils to opencadd (code moved)
• Update KLIFS Swagger URL (https://klifs.net/swagger/)
• Update KinFragLib paper citation in README

Release v1.0.0

KinFragLib: Exploring the Kinase Inhibitor Space Using Subpocket-Focused Fragmentation and Recombination.

This is the first KinFragLib release comprising the following resources as used/shown in the manuscript "Sydow, D., Schmiel, P., Mortier, J., and Volkamer, A. KinFragLib: Exploring the Kinase Inhibitor Space Using Subpocket-Focused Fragmentation and Recombination."

• Fragment library (as well as subsets of this fragment library tailored for recombination).
• Combinatorial library (due to its size, the data is NOT part of this repository but the link to its deposition at zenodo is provided: https://zenodo.org/record/3956580).
• Quick start notebook showing how to work with the fragment library.
• Notebooks covering the analyses on fragment and combinatorial libraries as shown in the associated paper.
