Property Insights of Nilestriol

The XLogP value of 4.3 indicates that Nilestriol is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 49.7 Ų, Nilestriol exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Nilestriol has 2 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
