Property Insights of Avermectin A1b

The XLogP value of 5.6414 indicates that Avermectin A1b is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 159.06 Ų indicates high polarity, suggesting Avermectin A1b may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Avermectin A1b has 2 hydrogen bond donor(s) and 14 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
