Cheminformatics in R โ analyse and screen small molecules with ChemmineR.
Drug Discovery & Pharmaceutical Sciences
Module-by-module breakdown of Analysis of Drug like Small Molecule using ChemmineR: A Cheminformatics Toolkit for R, from foundations to a certified capstone project.
Structures
โข SDF and SMILES formats, and importing them with ChemmineR
โข SDFset objects, validity checking and removing malformed structures
โข Standardisation: salts, tautomers and charge states before any comparison
Descriptors
โข Atom pair descriptors and fingerprints as implemented in ChemmineR
โข Physicochemical properties, and Lipinski and drug-likeness filtering
โข What a fingerprint captures and the structural information it discards
Similarity
โข Tanimoto coefficient and the threshold conventions used in practice
โข Similarity searching against a compound library
โข The similarity property principle and the activity cliffs that violate it
Clustering
โข Binning and hierarchical clustering of compound sets
โข Maximum common substructure and scaffold-based grouping
โข Visualising chemical space and the distortion any 2D projection introduces
Screening
โข Virtual screening workflows and enrichment assessment
โข Diversity selection and cherry-picking a subset for assay
โข ChemMine Tools and integration with the wider R analysis workflow
