Property Insights of Losalen

The XLogP value of 4.5311 indicates that Losalen is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 158.0 Ų indicates high polarity, suggesting Losalen may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Losalen has 4 hydrogen bond donor(s) and 11 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
