From: Quantitative prediction of selectivity between the A1 and A2A adenosine receptors
Chemical similarity of compounds of the selectivity classes A1AR-selective, A2AAR-selective, dual, and non-binders. The chemical similarity is visualized with t-SNE [20] based on FCFP4 fingerprints. a The used chemical clusters of the compounds: A1AR-selective, A2AAR-selective, dual binders, and non-binders. b Clusters based on chemical similarity; each color-symbol combination represents a unique cluster (136 clusters in total)
