Dimensionality Reduction

Interactively explore your chemical space with interpretable 2D projections. Use dimensionality reduction algorithms like PCA, UMAP, and t-SNE.

Cluster Analysis
k=5 — optimal clusters

Cluster Analysis & Medoids

Group your chemical space using clustering algorithms like k-means. Identify medoid molecules - the most central structure in each cluster – as representative compounds for testing.

Applications

Navigate chemical space with confidence

Library Diversity Assessment

Visualize how well your compound library covers chemical space. Identify gaps, redundancies, and under-represented regions before committing to synthesis or screening campaigns.

Hit Expansion

Starting from a cluster of active hits, explore neighboring chemical space to find structurally related analogs. Use medoids as representative scaffolds for focused follow-up.

Compound Triage

Filter libraries to manageable sizes by selecting diverse representative molecules. Reduce thousands of candidates to manageable shortlists for testing.
