Property Insights of Quinoline

The XLogP value of 2.0 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Quinoline. With a topological polar surface area (TPSA) of 12.9 Ų, Quinoline exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Quinoline has 0 hydrogen bond donor(s) and 1 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
