Property Insights of Gestrinone

The XLogP value of 2.2 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Gestrinone. With a topological polar surface area (TPSA) of 37.3 Ų, Gestrinone exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Gestrinone has 1 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
