Property Insights of TSAO-a3T

The XLogP value of 3.71292 indicates that TSAO-a3T is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 146.0 Ų indicates high polarity, suggesting TSAO-a3T may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, TSAO-a3T has 1 hydrogen bond donor(s) and 9 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
