Permeability proxy Check

Estimated from TPSA and LogP only: TPSA ≤ 90 Å² and −1 ≤ LogP ≤ 5 are treated as a favorable small-molecule permeability screen.

Lipinski's Rule of Five Fail 2 violations

MW ≤ 500 Da 474.5
LogP ≤ 5 -4.00
H-bond donors ≤ 5 6
H-bond acceptors ≤ 10 14

Veber's rules Fail

Rotatable bonds ≤ 10 9
