StructureMoa is a chemical-structure exploration tool. Structural similarity, clustering, and SAR relationships are intended for research exploration and do not establish shared potency, selectivity, safety, efficacy, or clinical performance.

Exploration score method

StructureMoa ranks are a rule-based Exploration Score. An LLM does not predict activity or efficacy. Role, SMILES, and relation signals inside each family are summed and cut into High / Medium / Low exploration priority.

Core tab

  • scaffold / payload / linker role weights
  • family center-compound bonus
  • SMILES source (db · known · pubchem · inherited)
  • relation-edge count and derived-child count

Derivative tab

  • drug / derivative / adc candidates
  • similarity to family center via Morgan fingerprint, radius 2, 2048 bits, Tanimoto
  • approved / clinical catalog-tag bonuses
  • ADC / payload tags

Explore tab

  • sparse SAR, cross-scaffold pairs, expansion leaves
  • weakly linked nodes and approved-tag neighborhood gaps
  • relation graph + stored Morgan fingerprints
  • category filters

Exploration-priority bins

  • High (X-S): top ~12%
  • Medium (X-A/X-B): ~12–62%
  • Low (X-C): remainder (pools under 5 compounds stay Medium)

Internal exploration metric based on catalog and structural signals. Not a prediction of efficacy, safety, potency, or development success.
