Property Insights of Avermectin B2A

The XLogP value of 4.5722 indicates that Avermectin B2A is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 190.29 Ų indicates high polarity, suggesting Avermectin B2A may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Avermectin B2A has 4 hydrogen bond donor(s) and 15 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
