Drug-likeness

Descriptor-based ADME screening flags from SMILES. These are not experimental toxicity results.

Permeability proxy Check

Estimated from TPSA and LogP only: TPSA ≤ 90 Ų and −1 ≤ LogP ≤ 5 are treated as a favorable small-molecule permeability screen.

  • TPSA ≤ 90 Ų 94.7
  • −1 ≤ LogP ≤ 5 4.09
Lipinski's Rule of Five Pass 1 violation
  • MW ≤ 500 Da 508.7
  • LogP ≤ 5 4.09
  • H-bond donors ≤ 5 2
  • H-bond acceptors ≤ 10 4
Veber's rules Pass
  • Rotatable bonds ≤ 10 7
  • TPSA ≤ 140 Ų 94.7
PAINS Alert

Matches PAINS filter: indol_3yl_alk(461). May be a frequent false positive in HTS — review carefully.
